Research, preparation, compilation, editing and layout of this book took approximately three years and more than 2,000 man hours. No one agency alone could have produced a book of this calibre. Each agency made a unique contribution to this book without which it would not have been a success. The Development Team would like to recognize and thank each agency director for making the commitment of resources to see this project through. Without their faith and trust to let this Project find its own way, this book would not exist. As new scientific information becomes available through basic and clinical research, recommended treatments and drug therapies undergo changes. The Development Team has done everything possible to make this book accurate, up–to–date and in accord with accepted standards at the time of publication. However, the reader is advised always ii to check product information regarding dose, contraindications before administering any drug. Caution is especially urged when using new or infrequently ordered drugs. This book is published under the Sunshine Act of Florida and is protected by applicable laws. Copies of this book may be purchased from any participating agency (subject to availability). This book may be cited as a source or used in its entirety with the permission of the Participating Agencies. PREFACE Preface Imagine if you will, the public outcry that would ensue if a jumbo jet filled with passengers crashed every day in the United States. Regrettably, Americans no longer need to imagine disasters that result in the tragic loss of lives. However, each day, more people die of sudden cardiac arrest than would fill a Boeing 747. The most effective way to improve the odds of survival for sudden cardiac arrest is rapid defibrillation in the pre-hospital setting. As high quality Emergency Medical Services (EMS) developed during the 1970s, cardiac arrest survival rates increased from near nothing to about 20% in a few progressive cities. However, essentially no additional progress in survival from cardiac arrest has occurred since 1980. For children, the odds of survival remain abysmal. Less than 2% of children with pre-hospital cardiac arrest survive to leave the hospital. Trauma systems developed during the 1970s to address the inadequacy of care for victims of traffic crashes. EMS began to transport patients directly to regional trauma centers, often bypassing closer community hospitals. With the establishment of these regional trauma centers the odds of survival from motor vehicle crashes improved. This reduction in mortality from injury illustrates the value of having EMS professionals who understand how to use the emergency care resources available in each community. EMS provides out-of-hospital medical care to those with perceived urgent needs. It is a component of the overall health care system. EMS delivers care as part of a system intended to attenuate the morbidity and mortality associated with sudden illnesses and injury. The positive effects of EMS care are enhanced by linkages with other community health resources and integration within the health care system. Emergency medical service is regarded as including the full spectrum of emergency care from recognition of the emergency condition, requesting emergency medical aid, provision of pre-hospital care, through definitive care in the hospital. The vast majority of patients cared for by EMS, however, are not victims of cardiac arrest or major injury. They have illnesses or injuries that are not life threatening yet require access to medical care. This textbook is a unique approach to EMS protocols because it is a regional approach that unifies the prehospital care across boundaries, additionally it was promulgated based upon sound research and evidence based medical care thereby affording the patient the best possible approach to field medicine available. The time for major advancement in the science and practice of EMS is here. Emergency Medical Service providers must be able to deliver state of the art care based on sound scientific knowledge. A number of us, our families, or our friends will at some point turn to local EMS providers for assistance; and we expect that they will provide us with the best care possible. These guidelines take into account the complexity of emergency care in today’s environment. The emergency team is afforded great latitude in treating the patient; it is difficult if not impossible to define every medical condition into a set of rules and procedures. One thing is certain though: not all the methods that we utilize today will stay the same during your career. This project is a living breathing entity that will be revisited, re-researched and updated as new technologies, procedures and treatments become standard. You as the provider of care have an obligation to not only follow these guidelines but to seek out new information that will contribute to the amassed knowledge that represents this book; some of the best ideas come from practicing Paramedics, EMTs and educators who let us know what problems they face every day in the field. This will allow the development team to keep the guidelines on the leading edge of patient care. Our goal is a High Performance EMS system that provides the patient with care that is second to none!! -Joseph V. Ferrara iii EMERGENCY MEDICAL GUIDELINES RATIONALE OF EMERGENCY MEDICAL GUIDELINES FOURTH EDITION The philosophy of the Medical Directors is to treat patients to the fullest, appropriate extent within the medical standard of care for the community. This is accomplished by focusing on the goals set forth by the American College of Emergency Physicians, the American Heart Association and other guideline setting organizations. Paramedics have the discretion to alter any treatment guideline if it is deemed inappropriate. Justification must be made in the run report and reviewed by the Medical Director. All personnel will be subject to examination of case reports. Inquiries are conducted by the Medical Director, Supervisor, Training Officer or their designee at any time during or after care is rendered. The Procedural Guidelines , Treatment Guidelines with exceptions as noted in the relevant sections are hereby authorized for use by the Emergency Medical Technicians and Paramedics in accordance with Florida Statute 401. These guidelines are intended to provide a general approach to treatment of patients by the Emergency Medical Team. It is not intended that the Emergency Medical Team blindly apply these medical guidelines to each patient. It is intended that the Emergency Medical Team use their professional and clinical judgment to determine the best course of treatment for each patient. The treatments and procedures identified as Medic Discretion are generally appropriate actions to be provided by the Emergency Medical Team without prior physician orders. The treatments and procedures identified as Physician Consult are generally appropriate actions to be provided by the Emergency Medical Team after discussion with on–line medical control and direct physician orders received. On-line medical control will be provided by the Emergency Department Physician at the receiving facility, or by the Emergency Department Physician of the base hospital should communications be hindered. Early contact should be made to the Emergency Department Physician whenever doubt exists as to proper management of any patient. Physicians who wish to direct the Emergency Medical Team in the care of a patient should be referred to the on-line medical control physician for issuance of orders to the Team. The Medical Directors authorize the Team Paramedic responsible for controlled substances to take them to the scene of a call. All responsibility for these controlled substances remain with the Paramedic. iv PREFACE v D.D.

GENERAL MEDICAL ABDOMINAL AORTIC ANEURYSMS Abdominal aortic aneurysm (AAA) is a relatively common. The Team should consider the possible etiologies of the pain: abdominal aneurysm in the elderly. perforated diverticulitis. is the rule for most patients with biliary tract disease. pancreatitis. Ruptured AAA is the 13th–leading cause of death in the US. AAA develops following degeneration of the media due to atherosclerotic changes. cardiac pain in epigastrium. Patients with a ruptured AAA may present in frank shock as evidenced by cyanosis. and proteoglycans. The clinician need not be afraid of properly palpating the abdomen because no evidence exists that aortic rupture can be precipitated by this maneuver. or groin pain for some time prior to rupture. rather than emergency care. gallbladder. mesenteric embolism or thrombosis. Establishing diagnosis in the field is usually difficult or impossible. or groin pain. This occurs with retroperitoneal expansion and pressure on either the right or left femoral nerve. flank. Expanding AAA causes sudden. It has a wide spectrum of presentations and should be considered in the differential diagnosis for a number of symptoms. survival rate drops by about 1% per minute. an AAA is even more difficult to palpate. recent trauma. vascular surgeons are unable to palpate a pulsatile mass while preparing the patient for surgery.

What gives the patient relief? If there have been previous attacks of somewhat similar pains. if the patient attempts to relieve the pain by walking the floor. or fainting can also accompany abdominal pain and furnish a rough guide to the severity of the pathologic process. i.. mesenteric arterial or venous thrombosis. the more delayed is the vomiting. careful diagnostic study. or diverticular disease are especially helpful.e. usually with appendicitis it is the initial site of pain before the pain shifts to the right lower quadrant. Vomiting is one of the most important. gastroenteritis is the probable diagnosis. Severe vomiting that precedes an intense epigastric. Vomiting usually occurs only 1 or 2 times/hour after the onset of pain with appendicitis. hematemesis. Does the pain radiate? Radiation often occurs along the distribution of the nerves of the same spinal segment (“referred pain”). Anticoagulants can increase the chances of bleeding. Some drugs (i. intestine.

Jaundice or evidence of bleeding in subcutaneous tissues is another diagnostic sign that may be present (i.9% Normal Saline – IV access is routinely established at a KVO rate. Promethazine (Phenergan) – Antiemetic/Analgesic. absent bowel sounds. (4) Pneumonia can lead to diffuse abdominal pain. Gastroenteritis is likely if family members or associates have had recent similar complaints. vomiting blood) or showing signs of impeding shock (postural hypotension) will require fluid resuscitation. Some relatively common diseases must be considered in the diffential diagnosis of acute abdominal pain. (1) Gastroenteritis: symptoms of colicky pain. volvulus of a gut with a common mesentery. which suggest the possibility of adhesions and intestinal obstruction. An ectopic pregnancy is life–threatening without emergency laparotomy. tabetic crises were a common cause of attacks of severe abdominal pain. complaints of burning pains are likely to remain unexplained. but the tenderness never becomes localized and the disease is self–limited. In the past. degree of distention and palpable masses are important. The center of attraction. Nasogastric Tube Insertion – Is indicated for the decompression of gastric distention and poisoning or overdose cases E-5 2/15/06 .

This medication can concentrate in pockets of obstructed bowel and possibly lead to rupture. imperforate anus. This patient can deteriorate rapidly. however. Use of this pain medication is preferred in abdominal pain because it provides rapid relief and is easily reversible. The most troublesome problem that occurs in young women is pelvic inflammatory disease. (10) Patients with psychogenic somatoform disorders often complain of severe attacks of abdominal pain for which no organic cause can be found. (7) Anticoagulants or severe coughing can lead to a hematoma of the abdominal wall or rupture of the deep epigastric artery or vein.

The sedative and analgesic properties of this medication may make diagnosis of abdominal pain difficult once the patient arrives at the emergency room. Dysmenorrhea may be trivial or disabling. Tenderness. (2) Inflammatory bowel disease: Crohn’s disease can mimic acute appendicitis. retroperitoneal bleeding from hemorrhagic pancreatitis or a bluish discoloration or frank ecchymosis of the costovertebral angles [Grey Turner’s sign} or around the umbilicus [Cullen’s sign}). (3) Herpes zoster: at times severe pain precedes the typical rash. In some instances symptoms are confined to the right lower quadrant so that there is great difficulty in determining whether the patient has pelvic inflammatory disease or appendicitis. Blood pressure. (11) Typhoid fever may. (6) Drug addicts may have severe colicky pains that suggest intestinal obstruction. (8) Sickle cell disease may be associated with attacks of severe abdominal pain.. patients who present with severe abdominal pain. uncontrolled vomiting. Intrauterine contraceptive devices may migrate into the peritoneal cavity and produce peritonitis and intestinal obstruction.EDUCATIONAL GUIDELINES web. Endometriosis is a common cause of pain. Therefore. Abdominal pain in women varies greatly in intensity. bloody stools. this disease must be considered. enterocolitis. Preferably it is treated with antibiotics. Tubo–ovarian abscesses require surgical treatment. High pitched peristalsis or borborygmi (bubbling in the bowels) in rushes suggest intestinal obstruction. this pain usually is chronic rather than acute. and others.e. of course. * Current research indicates the future of EMS leaning toward the use of a much higher concentration of normal saline as well as medications that allow for oxyhemoglobin enhancement. and diverticulitis can produce a similar syndrome (usually in the left lower quadrant). Severe pain combined with an absolutely silent abdomen is an indication for immediate exploration. Phenergan may be administered for prolonged. this can be confusing. Active peristalsis of normal pitch suggest a nonsurgical disease (i. Unless the patient has a peptic ulcer. (5) Acute myocardial infarction may be accompanied by diffuse abdominal pain.

NORMAL LABOR Labor consists of a series of rhythmic. urinalysis. The etiology of pre–eclampsia and eclampsia is unknown. labor usually lasts a maximum of 12 to 14 hours. since the disease process inevitably worsens at the time of delivery. Mild preeclampsia develops as borderline hypertension. One attempt at replacing the uterus may be made. which cuts off the supply of oxygenated blood from the placenta.

PROLAPSED CORD This condition refers to the situation in which the umbilical cord comes out of the vagina before the baby during delivery. LIMB PRESENTATION The presentation of an arm or leg through the vagina is an indication for immediate transport to the hospital. usually in multiparas or in patients with abnormalities of the uterus. The cause is unknown. Vaginal bleeding may be minimal. Preexisting conditions such as previous uterine surgeries can predispose a patient to this condition. Sudden.

EMS clinicians must meet the patient’s needs for pain control with the judicious use of medications. The synergistic potential of benzodiazepines and narcotics or antiemetics is significant for respiratory depression. DEFINITION Analgesia is defined as a reduced state of awareness of painful stimuli and sensation. UNDERSTANDING THE PATIENT’S NEEDS Meeting the patient’s needs for pain control can improve patient care and satisfaction during an encounter with emergency pre-hospital clinicians. However. Paramedics must continue to monitor and assess patients during pain control and be prepared to intervene in the event of a complication. Proper pain medication can decrease heart rate. Elderly and pediatric patients in particular are at increased risk during analgesia. and the paramedic must be attuned to the need for pain management even in the patient who does not verbalize pain. Furthermore. The medications used for moderate to severe pain control carry the potential for respiratory depression. padding with pillows and blankets at the point of contact. Pre-medication vital signs. Analgesia is used to minimize pain. especially if traction is applied on the cord before the placenta is completely separated. including a reduction in normal activities. vasovagal episodes.

PREMEDICATION PATIENT ASSESSMENT All patients receiving intravenous pain medication require a rapid pre-medication evaluation to determine relative risk versus benefit. hypercarbia. POTENTIAL FOR COMPLICATIONS Complications can occur in the pre-hospital environment as a result of over-sedation. The use of pain medication requires continuous intravenous access until patient care is transferred to the emergency department.24 PAIN CONTROL Opiates administered intravenously provide primary analgesia. Unrelieved acute and or moderate to severe chronic pain and poor symptom control can lead to anxiety and irritability. EKG and temperature are documented. Patients who are currently taking sedative or opioids may also be at a greater risk for over-sedation. created by medications that allow patients to tolerate unpleasant situations while maintaining adequate respiratory function.EMERGENCY MEDICAL GUIDELINES lacerations. These methods can include transport in the position of comfort. loss of self-esteem. The paramedic must have good access to the intravenous line and medication port throughout on-scene time transport.

Comfort and compassion are mainstays of medical care and their importance cannot be overemphasized. Establishing pain levels will become the fourth vital sign. Monitoring the patient’s mental status is one of the most valuable indicators of the efforts of pain management.

In other words. with up to 10% showing symptoms of schizophrenia or depressive psychoses. and with or without loss of muscle tone. so that attacks carry the risk of serious trauma. Petit mal seizures are genetically determined and occur predominantly in children: they never begin after age 20. Complex partial (psychomotor) seizures are characterized by a variety of patterns of onset.

These toxins cause peripheral vasodilatation. or toxic episodes (i. birth trauma). The presence of 2 of the following risk factors increase the probability of the first febrile seizure: family history. Partial continuous epilepsy is a form of rare focal (usually hand or face) motor seizures in which the attacks recur at intervals of a few seconds or minutes. Septic shock may develop due to the release of deadly toxins by the bacteria causing the infection. nasopharyngeal airway placement is sufficient for some patients. such as meningitis. relatively low fever at the time of seizure.

These areas of narrowing may become clinically significant and precipitate angina when myocardial demand increases.38 ACUTE CORONARY SYNDROME Initial diagnosis of acute coronary syndrome is based almost entirely on history. EDUCATIONAL GUIDELINES quently relieved with rest and without recent change in frequency or severity of activity necessary to produce symptoms is called chronic stable angina. Over time, the plaques may thicken and rupture, exposing a thrombogenic surface upon which platelets aggregate and thrombi form. The patient may note a change in symptoms of cardiac ischemia with a change in severity or of duration of symptoms. This condition is referred to as unstable angina. Other causes include arterial inflammation and secondary unstable angina. Arterial inflammation may be caused by or related to infection. Secondary unstable angina occurs when the precipitating cause is extrinsic to the coronary arterial bed, such as fever, tachycardia, thyrotoxicosis, hypotension, anemia, or hypoxemia. Most patients who experience secondary unstable angina have chronic stable angina. Irrespective of the cause of unstable angina, the result of persistent ischemia is myocardial infarction (MI). Angina becomes progressively more common, as does the underlying cardiac disease responsible, with increasing age. Typically, angina is a symptom of myocardial ischemia that appears in circumstances of increased oxygen demand. It usually is described as a sensation of chest pressure or heaviness that is reproduced by activities or conditions that increase myocardial oxygen demand. Not all patients experience chest pain. Some present with only neck, jaw, ear, arm, or epigastric discomfort. Other symptoms, such as shortness of breath or severe weakness, may represent anginal equivalent symptoms. Patients may complain of the following: palpitations, pain, which is usually described as pressure, squeezing, or a burning sensation across the precordium and may radiate to the neck, shoulder, jaw, back, upper abdomen, or either arm. Exertional dyspnea that resolves with pain or rest. Diaphoresis, nausea, and decreased exercise tolerance. Patients with diabetes and elderly patients are more likely to have atypical presentations and offer only vague complaints, such as weakness, lightheadedness, and nausea. Stable angina involves episodic pain lasting 5–15 minutes, provoked on exertion and relieved by rest or nitroglycerin. Unstable angina patients have increased risk for advance cardiac events, such as MI or death. Three clinically distinct forms exist, as follows: New–onset exertional angina, angina of increased frequency or duration or refractory to nitroglycerin, and angina at rest. Atherosclerotic plaque disease is the predominant cause. Coronary artery vasospasm is less common. Alternative causes of angina include ventricular hypertrophy due to hypertension, embolic occlusion of the coronary arteries, hypoxia, as in acute pulmonary disorders, cocaine and amphetamine use, underlying coronary artery disease, and inflammation of epicardial arteries. The immediate goal of emergency care is rapid identification of patients with AMI, and exclusion of alternative causes of nonischemic chest pain. RATIONALE The goals of treatment are to preserve patency of the coronary artery, augment blood flow through stenotic lesions, reduce myocardial oxygen demand thereby preventing major adverse cardiac events. All patients should receive antiplatelet agents, and patients with evidence of ongoing ischemia should receive aggressive medical intervention until signs of ischemia, as determined by symptoms and ECG resolve. Therapeutic benefit was seen for up to 12 hours but was the greatest when fibrinolytics were administered in the first 3 hours. Hence the cardiac alert criteria. Prehospital 12 lead ECG improves prehospital diagnosis, reduces hospital–based time to treatment, identifies patients requiring reperfusion, contributes to mortality reduction and facilitates triage to cardiac centers with interventional facilities. DRUG CATEGORY: Oxygen – Evidence suggests that breathing supplemental oxygen may limit the size of ischemic myocardial injury. DRUG CATEGORY: Anti-platelet agents – These inhibit cyclooxygenase, which in turn produces thromboxane A2, a potent platelet activator. Anti-platelet therapy has been shown to reduce mortality by reducing the risk of fatal strokes and fatal myocardial infarctions. Aspirin – Early administration of aspirin in patients with AMI may reduce cardiac mortality. After plaque rupture or erosion, a layer of platelets covers the surface of the plaque. Fibrinogen cross–links platelets, and the coagulation system is further activated by thrombin generation. At this stage the thrombus is platelet–rich. Therapy with antiplatelet agents is most effective at this time. Heparin – When Heparin is used in the presence of aspirin a reduction in mortality as well as a reduction in reinfarction has been seen. To reduce the incidence of increased intercrainial hemorrhage a lower dose of heparin is now recommended. DRUG CATEGORY: Nitrates – These agents oppose coronary artery spasm and reduce myocardial oxygen demand by reducing both preload and afterload. Nitroglycerin – (All forms) Causes relaxation of the vascular smooth muscle, causing a decrease in blood pressure. DRUG CATEGORY: Analgesics – These agents reduce pain, which decreases sympathetic stress, in addition to providing some preload reduction. Morphine Sulfate – Drug of choice (DOC) for narcotic analgesia because of its reliable and predictable effects, safety E - 39 2/15/06 EMERGENCY MEDICAL GUIDELINES profile, and ease of reversibility with naloxone. Morphine sulfate administered IV may be dosed in a number of ways and commonly titrated until desired effect is obtained. DRUG CATEGORY: Anticoagulants – These agents are used to prevent recurrence of clot after a spontaneous fibrinolysis Heparin – Augments activity of antithrombin and prevents conversion of fibrinogen to fibrin. Heparin does not actively dissolve but is able to inhibit further thrombogenesis. Parasympathetic influences during cardiopulmonary arrest have not been studied fully, and the clinical benefits of atropine have yet to be confirmed. High–dose epinephrine may improve the hemodynamics of CPR, thereby increasing the rate of return to spontaneous circulation; however, it has not been demonstrated to influence the final clinical outcome. Therefore, these doses no longer are recommended for children or adults. DRUG CATEGORY: Anticholinergic agents – The goal in using these agents is to improve conduction through the AV node by reducing vagal tone via receptor blockade. Atropine is a parasympatholytic agent used to eliminate vagal influence on the SA and AV nodes. Epinephrine (Adrenaline) Considered the single most useful drug in cardiac arrest. Used to increase coronary and cerebral blood flow during CPR. May enhance automaticity during asystole. Termination of efforts – A number of studies over the past decade observe consistantly that 1% of patients transported with continuing CPR survive to hospital discharge. It is now considered an unethical act to transport an arrest victim proven refractory to proper BLS and ACLS care. ASYSTOLE Asystole is cardiac standstill with no cardiac output and no ventricular depolarization; it eventually occurs in all dying patients. Asystole can be primary or secondary. Primary asystole occurs when the heart’s electrical system intrinsically fails to generate a ventricular depolarization. This may result from ischemia or from degeneration (i.e., sclerosis) of the sinoartial (SA) node or atrioventricular (AV) conducting system. Primary asystole usually is preceded by a bradydysrhythmia due to sinus arrest or complete heart block or both. It develops when cellular metabolic functions are no longer intact and an electrical impulse cannot be generated. Secondary asystole occurs when factors outside of the heart’s electrical system result in a failure to generate any electrical depolarization. In this case, the final common pathway is usually severe tissue hypoxia or acidosis. Asystole is associated with poor outcome regardless of its initial cause. Resuscitation is likely to be successful only if it is secondary to an event than can be corrected immediately. Prevalence of asystole as the presenting cardiac rhythm is lower in adults (25%–56%) than in children (90%–95%). Immediate diagnosis of asystole requires the recognition of full cardiac arrest and a confirmed flatline rhythm in 2 perpendicular leads. If the rhythm is truly asystole and has been present for more than several seconds, the patient will be unconscious and unresponsive. A few agonal breaths may be noted, but detectable heart sounds and palpable peripheral pulses are absent. Examples of common conditions that can result in secondary asystole include suffocation, near drowning, stroke, massive pulmonary embolus, hyperkalemia, hypothermia, and sedative–hypnotic or narcotic overdoses leading to respiratory failure. Hypothermia is a special circumstance, since asystole can be tolerated for a longer period of time under such conditions and can be reversed with rapid rewarming while cardiopulmonary resuscitation (CPR) is being performed. ATRIAL FIBRILATION Atrial fibrillation (AF) is a rhythm disturbance of the atria that results in irregular, chaotic, ventricular waveforms varying from bradyarrhythmia to tachyarrhythmia. Multiple re– entrant waveforms within the atria bombard the atrioventricular (AV) node, which becomes relatively refractive to conduction due to the frequency of upstream electrical activity. AF occurs in 3 distinct clinical circumstances: As a primary arrhythmia in the absence of identifiable structural heart disease. As a secondary arrhythmia in the absence of structural heart disease, but in the presence of a systemic abnormality that predisposes the individual to the arrhythmia. As a secondary arrhythmia associated with cardiac disease that affects the atria. Pertinent physical findings are limited to the cardiovascular system or, if embolization has occurred, the brain and/or peripheral vasculature. These include the following: Irregular pulse, with or without tachycardia, is described classically as the irregularly irregular rhythm. Hypotension and poor perfusion due to a decrease in atrial filling pressures and decrease in stroke volume. Signs of embolization, including transient ischemic attacks (TIAs) and cerebrovascular accidents (CVAs) may be identified. Congestive heart failure (CHF) Patients at the highest risk include those with long–standing hypertension, valvular heart disease (rheumatic), left ven- RATIONALE E - 40 2/15/06 EDUCATIONAL GUIDELINES tricular hypertrophy, coronary artery disease, or diabetes. CHF for any reason is a noted contributor to this disorder. Other causes may include: AMI, pulmonary embolism, cardiomyopathy, sick sinus syndrome, hyperthyroidism, ethanol use, cardiothoracic surgery, and use of over–the–counter herbs such (i.e., ephedra, ginseng) have been noted in some patients with new onset AF. When considering drug therapy for AF, remember the treatment caveat, “Electrical cardioversion is the preferred modality in the patient whose condition is unstable.” fibrillation (AF), which occurs in as many as 3% of certain populations. For the most part, morbidity and mortality are due to complications of rate (e.g., syncope, congestive heart failure – (CHF). In patients who suffer from flutter of the atria, the risk of embolic occurrences approaches that of atrial fibrillation (AF). A patient may present with a history of palpitations, fatigue or poor exercise tolerance, dyspnea, angina, or syncope. Pertinent physical findings are limited to the cardiovascular system. If embolization has occurred from intermittent AF, findings are related to brain and/or syncope. Tachycardia may or may not be present, depending on the degree of AV block that may be associated with the flutter activity. The rate may be regular or slightly irregular. Hypotension is possible but normal blood pressure is observed more commonly. CHF may be found and is usually be left ventricular dysfunction. Patients at the highest risk include those with long standing hypertension, valvular heart disease (rheumatic), left ventricular hypertrophy, coronary, coronary artery disease with or without depressed left ventricular function, or diabetes. Additionally, CHF for any reason is a noted contributor to this disorder. Additional causes include: postoperative revascularization, digitalis toxicity and pulmonary embolism. In cases of typical flutter, EKG reveals identically recurring regular saw tooth flutter waves. Flutter waves often are visualized best in leads II, III, AVF, or VI.. Flutter and fibrillation often coexist with alternating patterns (e.g., fib-flutter) in the same tracing. If the patient is unstable (e.g., hypotension, poor perfusion), synchronized cardioversion is commonly the initial treatment of choice. Cardioversion often requires low energies (<50J). If the electrical shock results in atrial fibrillation, shock at a higher energy level is used is used to restore normal sinus rhythm (NSR). To slow the ventricular response, dilitiazem may be the appropriate initial treatment. Adenosine produces transient AV block and can be used to reveal flutter waves. These drugs generally do not convert to NSR. If the flutter cannot be cardioverted, terminated by pacing, or slowed by the drugs mentioned, IV amiodarone has been shown to slow the ventricular rate and is considered as effective as digoxin. RATIONALE Rate control is the goal of medication in atrial flutter. When considering drug therapy for atrial flutter/fibrillation, electrical cardioversion is the preferred modality in the patient whose condition is unstable. Delivered energy should be syncronized with the QRS complex to reduce the possibility of inducing VF, which can occur when a shock “hits” the relative refractory portion of the cardiac cycle. Synchronized direct–current (DC) cardioversion is commonly the initial treatment of choice for the symptomatic patient. Cardioversion often requires low energeies. If the electrical shock results in atrial fibrillation, a second shock at a higher energy level is used to restore normal sinus rhythm (NSR). To slow the ventricular response, diltiazem is the appropriate initial treatment. Adenosine produces transient AV block and can be used to reveal flutter waves. This drug generally does not convert atrial flutter to NSR. DRUG CATEGORY: Calcium Channel Blocker – These agents reduce the rate of AV nodal conduction and control ventricular response. Diltiazem (Cardizem) is the DOC during depolarization. Inhibits calcium ion from entering slow channels or voltage– sensitive areas of vascular smooth muscle and myocardium. ATRIAL FLUTTER Atrial flutter is a rhythm disturbance of the atria that results in regular tachycardia ventricular waveforms. Atrial rates in atrial flutter are 240-400 beats per minutes. The QRS complexes are uniform in shape, but irregular in rate. P waves may have saw-tooth configurations. Multiple re-entrant or primarily generated (ectopic) atrial waveforms bombard the atrioventricular (AV) node. The most common form of atrial flutter involve a reentrant circuit that encircles the tricuspid annulus of the right atrium. Less commonly, atrial scars or atrial infarction may be the cause. Atrial flutter is less common than atrial CARDIAC TAMPONADE Pericarditis and cardiac tamponade are clinical problems involving the potential space surrounding the heart or pericardium. Pericarditis is one cause of fluid accumulation in this potential space; cardiac tamponade is the hemodynamic reE - 41 2/15/06 EMERGENCY MEDICAL GUIDELINES sult of the fluid accumulation. As the volume of pericardial fluid increases, the capacity of the atria and ventricles to fill is mechanically compromised, leading to reduced stroke volume and tamponade physiology. The pericardium (pericardial complex) consists of an outer fibrous layer and an inner serous layer. The fibrous pericardium is a flask–shaped, tough outer sac with attachments to the diaphragm, sternum, and costal cartilage. The serous layer is thin and is adjacent to the surface of the heart. The pericardium serves as a protective barrier from the spread of infection or inflammation from adjacent structures. The potential space produced by these layers contains approximately 20cc of fluid with electrolyte and protein profiles similar to plasma. Approximately 120cc of additional fluid can accumulate in the pericardium without an increase in pressure. Further fluid accumulation can result in marked increase in pericardial pressure, eliciting decreased cardiac output and hypotension (cardiac tamponade). The rapidity of fluid accumulation influences the hemodynamic effect. The early diagnosis of significant pericardial and cardiac injuries can prevent morbidity and enhance survival. Traumatic tamponade may present with acute dyspnea or altered mental status. Medical cardiac arrest patients may have a history of illness associated with the pericardium, particularly end–stage renal disease, severe infection, routine cardiac surgery and radiation therapy. Cardiac tamponade is influenced by volume and rate of accumulation. On physical exam a patient may present with jugular vein distention, hypotension, and muffled heart sounds (Beck’s triad). Hypotension and tachycardia without elevated jugular vein distension if associated hemorrhage is outside the pericardial sac. Pulses paradoxus is measured by careful auscultation with a blood pressure cuff. The first BP reading is recorded at the point when beats are audible during expiration and disappear with inspiration. The second reading is taken when each beat is audible during the respiratory cycle. A difference of more than 10 mm Hg defines pulses paradoxus. Cyanosis, varying degrees of consciousness may also be observed prior to cardiac arrest. Identification of any pericardial fluid in the setting of penetrating injury to the thorax or upper abdomen requires aggressive resuscitation. Hemopericardium is the most common feature of penetrating cardiac injuries. In acute massive hemopericardium, there is sufficient time for defibrillation to occur. The hemopericardium organizes and may partially clot, resulting in a pericardial hematoma. Potential causes of cardiac perforation include central line placement, pacemaker insertion, cardiac catheterization, and sternal bone marrow biopsies. A tamponade delay of hours to days has occurred secondary to catheter misplacement. E - 42 2/15/06 Cardiac arrest patients who present with traumatic injury or medical history as described require immediate treatment of the increase in pericardial pressure with pericardiocentesis. Removing as little as 30–50ml may produce dramatic hemodynamic improvement. The pericardium may have the potential of accumulating as much as 2,000 ml of fluid over time. For penetrating injuries, traumatic arrest, pulseless electrical activity (PEA), and asystole, the prognosis depends heavily upon the rapid identification of the potential for tamponade. CARDIOGENIC SHOCK Cardiogenic shock is characterized by a decreased pumping ability of the heart that causes a shock–like state with inadequate perfusion to the tissues. It most commonly occurs in association with, and as a direct result of, acute ischemic damage to the myocardium. The most common initiating event in cardiogenic shock is acute myocardial infarction (AMI). Dead myocardium does not contract, and once more than 40% of the myocardium is involved, cardiogenic shock may result. On a mechanical level, a marked decrease in contractility reduces the ejection fraction and cardiac output. These lead to increased ventricular filling pressures, cardiac chamber dilation, and ultimately, univentricular or biventricular failure that result in systemic hypotension and/or pulmonary edema. Mortality rates for medically treated patients with AMI and cardiogenic shock exceed 70%. Most patients with cardiogenic shock have an AMI and, therefore, present with the constellation of symptoms of acute cardiac ischemia (i.e., chest pain, shortness of breath, diaphoresis, nausea and vomiting). Patients experiencing cardiogenic shock also may present with pulmonary edema and presyncopal or syncopal symptoms. Physical exam often reveals that the patient is in the middle of an AMI. Patients are in frank distress, are profoundly diaphoretic, and have severe shortness of breath and chest pain. Neck examination may reveal jugular vein distention, which may be prominent. This finding is evidence of right ventricular failure. With increasing ventricular dysfunction, florid pulmonary edema and severe hypotension may develop. Auscultation of the chest may reveal varying degrees of congestive heart failure. Prehospital care is aimed at minimizing ischemia and shock. RATIONALE The goals of pharmacotherapy are to reduce morbidity and prevent complications. Early hemodynamic stabilization is beneficial and reduces mortality. DRUG CATEGORY: Vasopressors – These drugs aug- EDUCATIONAL GUIDELINES ment both coronary and cerebral blood flow present during the low–flow state associated with shock. Sympathomimetic amines with both alpha–adrenergic abd beta–adrenergic effects are indicated. Dopamine is the drug of choice to improve cardiac contractility.

Lower doses predominantly stimulate dopaminergic receptors that in turn produce renal and meseneric vasodilation. Higher doses cause cardiac stimulation and renal vasodilation. reassess patient status. The responsible clinician should stop the resuscitative effort when he or she determines with a high degree of certainty that the arrest victim will not respond to further ACLS efforts. No reliable criteria are available to determine neurological outcome during cardiac arrest. TRAUMATIC CARDIAC ARREST Treatment of patients in cardiopulmonary arrest varies as to the mechanism of the injury and whether or not they exhibit any signs of life (pulse, respirations, or reflexes) on initial evaluation. Generally, trauma patients who are found with no signs of life in the field have suffered overwhelming cardiovascular or CNS injuries, which are not amenable to surgical treatment under any circumstances. The survival rate on these patients is essentially zero and attempts at resuscitation are futile. Patient’s suffering traumatic cardiopulmonary arrest after treatment has begun should be Diverted to the closest facility. Due to the rapid response from providers to scenes, many traumatic arrest patients are not yet in asystole, but present on exam to be in Pulseless Electrical Activity (PEA). In this case the provider should follow protocol and attempt to address all of the physiologic causes of PEA while enroute to the emergency department. These patients should also be diverted to the closest facility. CESSATION OF EFFORTS Patients in cardiac arrest exhibiting asystole have a dismal rate of survival – usually as low as 1 or 2 people out of 100 cardiac arrests. As with PEA, the only hope for resuscitation of a person in asystole is to identify and treat a reversible cause. The asystole protocol outlines an approach that focuses on “not starting” and “when to stop”. Field personnel will not be required to transport every victim of cardiac arrest to the hospital emergency department. However, transportation with continuing CPR and ALS interventions is justified if there are interventions available in the ED that cannot be performed in the field (such as central core re-warming equipment) or field interventions (such as tracheal intubation) that where unsuccessful in the field, or patient’s who do not have a valid state of Florida DNRO. For nontraumatic cardiac arrest solid evidence confirms that ACLS care in the ED offers no advantage over ACLS care in the field. Children are a special case. A pulse may be difficult to find without a Doppler. In any case, you should be especially aggressive in attempting to resuscitate children with no palpable pulse. Pregnant mothers and the newly born will also be conditions in which we will continue maximum efforts including transport. Likewise, it is inappropriate for personnel to apply routine “stopping rules” without thinking about their particular situation. Cessation of efforts in the pre-hospital setting, following system-specific criteria and under direct medical control will be standard practice in your EMS system. Healthcare professionals must understand the patient, the arrest features, and the system factors that have prognostic importance for resuscitation. These include time to CPR, time to defibrillation, pre-arrest state, and initial arrest rhythm. None of these factors alone or in combination is clearly predictive of outcome. The most important factor associated with poor outcome is time of resuscitation efforts. The chance of discharge from the hospital alive and neurologically intact diminishes as resuscitation time increase. Clinicians must constantly RATIONALE Not starting & Stopping Resuscitation One goal unique to CPR is the reversal of clinical death, an outcome achieved in only a minority of patients. However, the performance of CPR, may conflict with the patient’s own desires and requests or may not be in his or her best interest. Resuscitative efforts may be inappropriate if goals of patient care cannot be achieved. Each decision must be made for the individual, with compassion, based on ethical principles and available scientific information. Medical treatment is futile if its purpose cannot be achieved. The 2 major determinants of medical futility are length of life and quality of life. An intervention that cannot establish any increase in length or quality of life is futile. In resuscitation a qualitative definition of futility must include low chance of survival and low quality of life afterward. Key factors are the underlying disease before cardiac arrest and expected state of health after resuscitation. A careful balance of the patient’s prognosis for both length of life and quality of life will determine whether CPR is appropriate. CPR is inappropriate when survival is not expected or if the patient is expected to survive without the ability to communicate. The framework for decisions about futility can be best achieved by a social consensus. Discussion and debate among E - 43 2/15/06 that is when the patient is dead.

SVT may be classified as an atrial or atrioventricular tachyarrhythmia. a common clinical condition. one study found that one third of patients with SVT experienced syncope. It is helpful to characterize SVT by comparing the RP interval to the PR interval. A 12 lead ECG allows classification of the tachyarrhythmia. ineffective cardioversion/defibrillation.

If the magnet is left on for approximately 30 seconds. particularly oversensing of the diaphragm or pectoralis muscles. exceptions include atrial fibrillation (AF) and multifocal atrial tachycardia (MAT). In the absence of manifest preexcitation (i. skin erosion. In AVRT. the P wave is found within the QRS complex or shortly after the QRS complex. When impulses travel down the accessory pathway in an anterograde manner. Following termination of the tachycardia. an ECG should be obtained during sinus rhythm to screen for WPW syndrome. It does not however. Conduction begins at the sinus node. Extremely rapid ventricular rates during AF or atrial flutter can cause deterioration to ventricular fibrillation. the risk of sudden death with PSVT is extremely PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA (PSVT) Paroxysmal supraventricular tachycardia (PSVT) is episodic with an abrupt onset and termination.

Use of a magnet over the ICD inhibits further shocks. Palpitations and dizziness are the most common symptoms reported by patients with SVT. they may be normal or abnormal depending on the mechanism of atrial depolarization. More than 90% of patients convert to sinus rhythm with adenosine 12mg. Lidocaine is the DOC in the setting of complex ectopy in the peri–MI period if the patient is symptomatic. As a result of its short half–life. With electrolyte imbalances. lidocaine shortens repolarization. DRUG CATAGORY: Calcium Channel Blocker – This drug decreases conduction velocity and prolongs the refractory period. even though about half have no clinical symptoms to suggest PE. correction of abnormalities is therapeutic. This. The net effect is to decrease firing of ectopic foci and allow a normal rhythm to reassert itself. platelets. Adenosine (Adenocard) is a first–line medical treatment for termination of PSVT. being second only to coronary artery disease as a cause E . In drug toxicity specific therapies are available. A good clinician actively seeks the diagnosis as soon as any suspicion of PE whatsoever is warranted. It also increases the refractory period via blockade of calcium influx.51 PREMATURE VENTRICULAR CONTRACTIONS (PVC) Therapy for complex ventricular ectopy depends on the setting and the underlying cause. Myocardial excitability is reduced by causing an increase in the threshold for excitation and inhibition of ectopic pacemaker activity. yet no firm evidence supports this practice. The belief that calf vein deep vein thrombosis (DVT) is only a minor threat is outdated and inaccurate. the diagnosis is missed far more often than it is made. It is effective in terminating both AVNRT and AVRT. because prompt diagnosis and treatment can dramatically reduce the mortality rate and morbidity of the disease. it is an often–fatal complication of underlying venous thrombosis. PE is the third most common cause of death in the US. It may be effective when Lidocaine has not achieved suppression. It is a short–acting agent that alters potassium conductance into cells and results in hyperpolarization of nodal cells. Unfortunately. Massive PE is one of the most common causes of unexpected death. Lidocaine suppresses ventricular arrhythmias predominatly by decreasing automaticity by reducing the slope of diastolic depolarization as seen in the QRS complex. Lidocaine seems to be more effective during AMI. Under pathological conditions. thetic properties may also help to suppress ventricular ectopy during an AMI. Furthermore. prevent complications. These arrhythmias depend on AV nodal conduction and therefore can be terminated by transiently blocking AV nodal conduction. Pulmonary thromboembolism is not a disease in and if itself. microthrombi (tiny aggregates of red cells. and reduce morbidity. in turn. 90% of tachycardia due to AVNRT or AVRT can be terminated with Adenosine.

DRUG CATEGORY – Antiarrhythmics – These agents alter the electrophysiologic mechanisms responsible for PVC’s. and fibrin) are formed and lysed continually with the venous circulatory system. DRUG CATAGORY: Antiarrhythmic agents – These drugs can be used to treat or prevent arrhythmia. Studies suggest that nearly every patient with thrombus in the upper leg or thigh will have a PE if a sensitive enough test is done to look for it. one third of the cases of massive PE have their only identified source in the veins of the calf. stops the reentrant phenomenon. It increases the refractory period of the atria and the ventricles. because PE often causes only vague and nonspecific symptoms. The toxic–to–therapeutic balance is delicate. This increases the threshold to trigger an action potential and results in sinus slowing and blockage of AV conduction.EDUCATIONAL GUIDELINES low. Its local anes- 2/15/06 . Patients who are hemodynamically unstable should be resuscitated immediately with cardioversion. PE occurs when these clots break loose and embolize to block pulmonary blood vessels. The majority of the patients who present with PSVT have AVNRT or AVRT. RATIONALE The goals of pharmacotherapy are to correct arrhythmia. Rather. microthrombi may escape the normal fibrinolytic system to grow and propagate. Procainamide may also be used to treat PVC’s. adenosine is best administered in an antecubital vein as an IV bolus followed by a rapid saline infusion. DVT of the calf is a significant source of PE and often causes severe morbidity or death. Lidocaine stabilizes cell membranes and blunts action potential. This dynamic equilibrium ensures local hemostasis in response to injury without permitting uncontrolled propagation of clot. Diltiazem (Cardizem) Decreases conduction velocity in the AV node. PULMONARY EMBOLISM (PE) Pulmonary embolism (PE) is an extremely common and highly lethal condition that is a leading cause of death in all age groups. Current techniques allow us to demonstrate PE in 60–80% of these patients. In fact. high fever. acidosis). Patients may present with recordable aortic pressures and absent peripheral pulses from weak cardiac contractions or severe peripheral vascular disease. because IV fluids may worsen the patient’s condition. new onset of wheezing. and severe CHF.

PEA is caused by the inability of cardiac muscle to generate a sufficient force despite an electrical depolarization. back pain. The overall mortality rate is high in patients in whom PEA is the initial rhythm during cardiac arrest. digitalis. any new cardiac arrhythmia. The classic triad of signs and symptoms of PE are hemoptysis. The most important clinically identifiable risk markers for DVT and PE are a prior history of the same. because the diagnosis is unsuspected until autopsy in approximately 80% of cases.

Physiologic causes of increased vagal tone include bradycardia seen in athletes. bronchial smooth muscle relaxation. dyspnea. RATIONALE Drug treatment for sinus bradycardia usually is not indicated for asymptomatic patients. atropine and pacing usually are not recommended because of myocardial irritability. Epinephrine (Adrenalin) has alpha–agonist effects that include increased peripheral vascular resistance. Sick sinus syndrome occurs most commonly in elderly patients with concomitant cardiovascular disease and follows an unpredictable course. However. few patients actually become symptomatic until their heart rate drops to less than 50 beats/minute. causing an increase in cardiac output. although it may reveal the following signs: decreased level of consciousness. where available. Main therapeutic effects are cardiac stimulation. In symptomatic patients. systemic hypotension. isoproterenol was used quite commonly in patients with bradycardia. Routine administration is discouraged because it worsens intracellular and intracerebral acidosis and is not proven to benefit mortality. TCA.

Sudden loss of cardiac output with subsequent tissue hypoperfusion creates global tissue ischemia. Atropine is used to increase heart rate through vagolytic effects. VT degenerates into VF. and is associated with sudden death due to either primary ventricular fibrillation or torsade that degenerates into ventricular fibrillation. The acquired conditions that predispose one to torsade either decrease the outward potassium current or interfere with the inward sodium and calcium currents. Because of the critical importance of early defibrillation.000 SCD cases in the US annually. Differentiating between these entities. palpitations.54 2/15/06 Ventricular fibrillation (VF) is a pulseless arrhythmia with irregular and chaotic electrical activity and ventricular contraction in which the heart immediately loses its ability to function as a pump. it generally should not be used in combination with another agent that prolongs the QT interval. therefore.000 sudden cardiac deaths occur per year. The ventricular rate can range from 150 beats per minute (bpm) to 250 bpm. VF usually develops secondary to an area of myocardial ischemia with a lowered fibrillation threshold. An often–described R–on–T extrasystole phenomenon may account for many VF cases. VF is the primary cause of sudden cardiac death (SCD). In the absence of ischemic heart disease. drive pacing may be necessary at a rate of up to 140 bpm to control the rhythm in a patient with torsade who is in extremis.

VF causes loss of oxygen to vital organ systems and brain death in minutes. it is thought to be responsible for more than 400. Ventricular tachycardia (VT) often precedes onset of VF in these cases. Other drugs that prolong the QT interval and have been implicated in cases of torsade include phenothiazines. Prolongation of the QT interval may be congenital. Interventions that impact survival and outcome of resuscitation include: early recognition of an arrest. VF has been described as the initial rhythm in almost 70% of out–of–hospital arrests. causing increase in cardiac output.

Chest pain. is an uncommon variant of ventricular tachycardia (VT). prolonged QT syndromes. conduction disturbances creating abnormal electrical propagation of the action potential. and ACLS. the single most useful drug in cardiac arrest. Bystander CPR reportedly plays a significant role in prolonging the period (up to 12 min) in which VF may respond to a defibrillator. AEDs identify VF more rapidly than manual defibrillation techniques. Epinephrine is considered the most useful drug in cardiac arrest.. AICD effectively provides early defibrillation.EDUCATIONAL GUIDELINES Automated external defibrillators (AEDs) have revolutionized prehospital VF management because they have eliminated the need for rhythm–recognition training. forcing certain institutions and prehospital provider authorities to opt to ignore the ACLS updated recommendations pertaining to the use of Amiodarone. tive is to interfere with all reentrant arrhythmia and allow any intrinsic cardiac pacemakers to assume the role of primary pacemaker. Drug therapy may consist of sympathomimetics. prognosis is poor. In addition. Their use has resulted in increased survival rates and improved prognosis for patients in VF arrest. Lidocaine is the DOC for VF refractory to defibrillation and epinephrine.e. Post–defibrillation arrhythmias (mainly atrioventricular AV blocks) have been reported in up to 24% of patients. It is a Class 11B drug by ACLS criteria. Few survive when VF lasts more than 8 minutes without intervention. This means that fair to good evidence supports its use in humans. antiarrhythmics used successfully should be continued and control any hemodynamic instability. Prognosis for survivors of VF strongly depends on the time elapsed between onset and medical intervention. CPR may increase the number of patients in VF who benefit from defibrillation by response personnel. AEDs should not be used during emergency transport because patient movement creates the risk of inadvertent defibrillation. Early defibrillation often makes the difference between long–term disability and functional recovery. Controversy surrounds the issue of Lidocaine vs Amiodarone because providers have expressed reluctance to accept the recommendations. Biphasic waveform defibrillation shocks (repeated at < or = 200j) have equivalent or higher success for eventual termination of VF than monophasic defibrillators that increase the current (200.

Recent American Heart Association (AHA) and ACLS recommendations promote amiodarone as superior to the conventional use of Lidocaine. In refractory VF additional medications such as magnesium and/or procainamide may be effective (class IIb). The medication administration treatment goals are to electrically terminate VF so that an organized electrical rhythm follows and restores cardiac output. vasopressin is used only once in pulseless VT and VF. Lidocaine is a class 1B antiarrhythmic that increases electrical stimulation threshold of the ventricle. The incidence is related to the amount of energy used for defibrillation. However.

Success rates significantly decrease as the duration of ischemia increases. 360j) with successive escalating shocks. Automated implantable defibrillators (AICDs) are used for patients at high risk for recurrent VF. suppressing automaticity of conduction through the tissue. DRUG CATEGORY: Antiarrhythmics – Alter electrophysiologic mechanisms responsible for arrhythmia. Studies indicate patients with VF arrest who receive AICDs have improved long–term survival rates compared to those receiving only medications. Without intervention. the difficulty in drawing up and storing this medication and the cost of administration of amidodarone has been restrictive. and establish the need for emergent interventions. Amiodarone – May inhibit AV conduction and sinus node function. DRUG CATEGORY: Sympathomimetics/ Vasopressors – Augment both coronary and cerebral blood flow present during low flow states associated with CPR. the rate of survival out of the hospital is not increased in patients who receive Amiodarone. Post–resuscitation death and disability after successful resuscitation directly correlate with the amount of CNS damaged during the event. hypocalcemia. VT tends to deteriorate into unstable states and more malignant dysrhythmias. wide QRS complexes (>120ms). with varying QRS complexes). This degeneration also is the usual source of mortality in VT. VT generally has a favorable short–term outcome. VT may be monomorphic (typically regular rhythm originating from a single focus with identical QRS complexes) or polymorphic (may be irregular rhythm. characterized by a rate typically greater than 120 beats per minute and wide QRS complexes. Sodium bicarbonate is used only when the patient is diagnosed with bicarbonate–responsive acidosis. rales. its role in VF is limited due to the time it takes procainamide to reach therapeutic levels when administered IV. or altered level of consciousness. Magnesium sulfate. Long–term prognosis depends upon the underlying VENTRICULAR TACHYCARDIA (VT) Ventricular tachycardia (VT) is a tachydysrhythmia originating from a ventricular ectopic focus. Magnesium supplementation is used to treat torsades de pointes. Stable VT patients do not experience symptoms of hemodynamic decompensation. Unlike other dysrhythmias. rate greater than 100 beats per minute (usually 150–200). increased automaticity (which tends to favor ectopic foci). hypoxemia. hypokalemia. with breakdown of normal conduction patterns. and hypomagnesemia. and activation of re–entrant pathways in the ventricular conduction system. Myocardiac excitibility is reduced by an increase in threshold for excitation and inhibition of ectopic pacemaker activity. which should be sought and treated aggressively. a longer duration is considered VT. VT is generally a symptom of coronary artery disease (CAD) or structural heart disease. Magnesium sulfate acts as an antiarrhythmic agent. yet it often causes severe hemodynamic compromise and may deteriorate rapidly into ventricular fibrillation (VF). and sodium bicardbonate are used in VF secondary to other medications. or severe refractory VF. presence of atrioventricular (AV) dissociation. palpitations. VT is one of the most frequently observed dysrhythmias. yet the principal morbidity comes from its tendency to degenerate spontaneously into VF. Most patients present to the emergency worker with symptoms of either ischemic heart disease or hemodynamic compromise resulting from poor perfusion. However. or Phenobarbital overdose. anxiety and diaphoresis. If treated rapidly. Symptoms may include chest pain. It moderates nerve and muscle performance by regulating the action potential excitation threshold. hypotension and an altered mental status. known or suspected hypomagnesemia. Consider all patients with VT to have active myocardial ischemia. Nonsustained VT is defined as a run of tachycardia of less than 30 seconds duration. Physical findings usually reflect the degree of hemodynamic instability such as symptoms of CHF (dyspnea. or calcium channel blocker toxicity. Calcium chloride is also useful in the treatment of hyperkalemia. and calcium chloride is used to treat VF caused by hyperkalemia.56 2/15/06 . Arrhythmia may occur with or without either myocardial ischemia or infarction. dyspnea. several factors suggest VT including a E . A distinctive variant of VT is torsade de pointes. VT can produce congestive heart failure and hemodynamic compromise. indicating rate and stroke volume are not providing adequate cardiac output. Ventricular tachycardia may develop without hemodynamic deterioration. Deficiency in magnesium sulfate is associated with cardiac death and can precipitate refractory VF. type 1a antiarrhythmics and hypomagnesemia). tricyclic antidepressant. Unstable VT is characterized by symptoms of insufficient oxygen delivery such as chest pain. Electrolyte and sympathomimetics may increase the likelihood of VT in the susceptible heart. hyperkalemia. Patients with presistant or recurrent VF following antiarrhythmic administration should be assessed for underlying electrolyte abnormalities as a a cause for their refractory dysrhythmia. and fusion beats. However. DRUG CATEGORY: Electrolytes – Are considered therapeutic alternatives for refractory VF.e. No absolute ECG criteria exist for establishing the presence of VT. Sodium bicarbonate is used as an alkalinizing agent. hypotension. VT can be triggered by electrolyte deficiencies and the use of sympathomimetic agents (from relatively benign caffeine to more potent agents such as methamphetamine or cocaine) may stimulate VT in vulnerable hearts. and jugular vein distention). Routine use is not recommended.. VT usually is a consequence of structural heart disease. Procainamide increases the refractory period of the atria and ventricles. Among electrolyte abnormalities associated with VF are hyperkalemia. It typically occurs from drugs or conditions that prolong the QT interval (i. calcium chloride. with its unusual shifting–axis QRS complexes that appear as if the heart is rotating upon an axis.EMERGENCY MEDICAL GUIDELINES tory period in the myocardium and inhibits adrenergic stimulation. Emergency workers must determine if the VT is stable or unstable. Procainamide may be effective when lidocaine is not. failure to synchronize the shock with the patient’s QRS may precipitate VF. Both procainamide and amiodarone have vasodilatory effects which WOLFF–PARKINSON–WHITE SYNDROME Preexcitation is defined as. ECG is the diagnostic modality of choice for confirming that the patient’s tachycardia is VT. This arrhythmia will recur and seldom remains stable. but it is effective in treating hemodynamically unstable VT and VF. blood pressure monitoring for hypotension is critical. verapamil. acts as an antiarrhythmic. Lidocaine will more effectively suppress ventricular arrhythmias associated with acute myocardial ischemia and infarction once they occur. the whole or some part of the ventricular muscle is activated earlier by the impulse originating from the atrium than would be expected if the impulse reached the ventricles by way of the normal specific conduction system only. can destabilize hemodynamic status. Antiarrhythmic agents that have direct effects on accessory pathway conduction and reE . thereby answering the question – is the patient’s clinical presentation so severe that immediate electrical cardioversion is required or can the patient be managed adequately with pharmacological agents. Furthermore. although an electrolyte. The net effect is to decrease firing of ectopic foci to allow a normal rhythm to reassert itself. Although lidocaine can be administered rapidly with minimal effect on blood pressure. Emergency workers should be familiar with this syndrome and the proper treatment of its associated arrhythmias to avoid unnecessary morbidity and mortality. IV amiodarone may be better tolerated than procainamide. With this in mind. if in relation to atrial events. These agents alter the electrophysiologic mechanisms responsible for arrhythmia. there is the potential for extremely rapid ventricular responses during AF with degeneration to VF. monomorphic or polymorphic VT. Procainamide slows down phase 4 (diastolic) depolarization. it is a second choice. synchronized electrical cardioversion is always indicated. the clinician should never use more than 1 agent unless absolutely necessary. and antiarrhythmic therapy. If patients are clinically unstable. and possibly intravenous μ–blockers can cause a paradoxical increase in ventricular response rates in these patients with WPW. However. Unstable VT is treated with immediate synchronized cardioversion. Proarrhythmias (torsades de pointes)are serious tachyarrhythmias or bradyarrhythmias seemingly generated by antiarrhythmic agents. Of the various preexcitation syndromes. supplemental oxygen. In some patients a conduction pathway bypasses the AV node. Procainamide is contraindicated because of it’s QT prolongation potential. DRUG CATEGORY: Vasopressor – Augment both coronary and cerebral blood flow present during low flow states. This drug can also be expected to reach therapeutic levels slightly slower than Lidocaine. when an appropriate dose of a single antiarrhythmic medication fails to terminate an arrhythmia. during pharmacological interventions and after conversion to a regular rhythm. Such a conduction pathway is called an accessory bypass tract. Magnesium Sulfate is the DOC for torsades de pointes. DRUG CATEGORY: Antiarrhythmics – Mainstay treatments for clinically stable VT are antiarrhythmic drugs.57 2/15/06 . if this drug is selected by the clinician. Digitalis. magnesium sulfate. Procainamide is another antiarrhythmic agent known to effective in treating a broad variety of arrhythmias. Most patients respond to low levels of electrical energy. studies suggest that it is relatively ineffective for termination of VT and less effective against VT than IV procainamide. Polymorphic VT of the torsade de pointes type should be treated immediately because of the frequent transition to unstable VT. Other drugs are preferred over lidocaine in each VT scenario. ECG should be obtained before. In most patients. However. however torsades may be drug induced (proarrhythmic) or the result of an underlying magnesium deficiency. Lidocaine is appropriate for stable. Simultaneous 3–channel recordings and 12–lead tracings are more helpful than rhythm strips to analyze this dysrhythmia. Amiodarone has not been studied specifically for the termination of hemodynamically stable VT. Lidocaince may be utilized. In the stable VT setting. and slows intraventricular conduction. In these instances. In a few patients who have downward conduction through this pathway. turning to electrical cardioversion rather than a second antiarrhythmic medication is now exceptable. diltiazem. followed by expeditious airway management as needed. the most common is Wolff– Parkinson–White (WPW) syndrome. vascular access.

In recent years it has become a popular recreational drug among dance clubs. GHB is synthesized from a chemical used to clean electrical circuit boards. It is available in both liquid powder forms. Often used in combination with other drugs, such as ecstasy, it is odorless and tasteless. GHB effects can be felt within 5 to 20 minutes after ingestion and the high lasts about 1.5 to 3 hours. Because it is odorless and tasteless it can be slipped into someone’s drink undetected. SIGNS AND SYMPTOMS CNS depression Nausea Respiratory depression Seizures Anticholinergic: flushing, dry mouth, dilated pupils Cardiovascular: QRS greater than 0.12 sec, bundle branch block, AV blocks, sinus tach, PVC’s, ventricular bigeminy, V– tach, V–fib, bradycardia, cardiac arrest, hypotension, pulmonary edema Worldwide, greater than 9 million natural and synthetic chemicals have been identified; fortunately, fewer than 3000 cause greater than 95% of accidental and deliberate poisonings. Identifying a poison and accurately assessing its potential toxicity are critical. Poisoning should be considered in the differential diagnosis of any unexplained symptoms or signs, especially in children less than 5. Similarly, in the young adult, any disparity between expected history and clinical findings should suggest poisoning. Recently, poisonings among the elderly (especially medication mix–ups), among hospitalized patients (drug errors), among workers exposed to occupational chemicals, and as a result of environmental pollution have been increasingly recognized. Often the type and speed of onset of the total clinical picture will confirm or refute a suspicion of poisoning. Occasionally, the absence of a specific finding will be as important as its presence. Any pertinent history should be secured and the person and premises inspected for traces of drugs; i.e., imprint identifications on solid medication forms, alcohol, etc, particularly for the unconscious patient. Specific antidotes: While not numerous, specific antidotes are remarkably effective; i.e., naloxone in opioid overdoses, atropine in organophosphate encounters, methylene blue for methemoglobinemia, acetylcysteine for acetaminophen, Digibind® for digoxin. A poison center should be contacted to determine if new specific antidotes have been developed, particularly for new drugs. Inhaled poison: The patient should be removed from the contaminated environment, his respiration supported, and other personnel protected from contamination. POISONING/OVERDOSE A relatively small percentage of the cases of poisoning and drug overdose are actually life–threatening situations when the Team arrives. Calm management of suspected poisonings include securing evidence from the scene and careful initial assessment of the patient. Suicidal patients should not be allowed to refuse care without law enforcement present to accept responsibility. Be alert for possible violent acts. Prompt consultation with the emergency room is appropriate. The Team should give special attention to neurological findings such as: level of consciousness., pupils, eye movement, gag reflex and response to pain. TRICYCLIC ANTIDEPRESSANTS (TCA) Tricyclic antidepressant overdose is probably the most common serious drug overdose encountered today. It represents an true medical emergency and is associated with approximately 20 % mortality rate. The tricyclic antidepressants remain a major cause of toxic death in the U.S. The standard of care for significant TCA overdoses includes a rapid assessment, aggressive airway management in the patient with deE - 62 2/15/06 EDUCATIONAL GUIDELINES Skin and eye contamination: Contaminated clothing (including shoes and socks) should be removed. The skin should be thoroughly washed and the eyes flushed with water. around visualization and palpation of all areas of the abdomen. This does not preclude that standard traumatic primary surveys should not be completed. In fact, this is just a small part of the overall assessment of any trauma patient. After the removal of all clothing in the region, the entire abdominal region needs to be visually assessed and manually palpated. Consideration should be given during clothing removal for the maintenance of legal evidence if it is needed (i.e., GSWs, stabbings, etc.). Following the standards put forth by BTLS International, the acronym “DCAP–BLS TIC” can be followed (deformity– contusion–abrasions–penetrations–burns–lacerations– swelling–tenderness–instability–crepitus). One also must remember that any signs of intra–abdominal trauma seen in the pre– hospital setting, typically indicates a significant underlying injury since abdominal injuries typically do not manifest themselves early. Abdominal distention or tenderness is considered to be an indication for immediate transport following a traumatic incident. Although auscultation and percussion of the abdomen are “nice” to complete during assessment, time should not be wasted in the pre–hospital setting since the benefits of such are minimal. Management of the abdominal trauma patient typically revolves around the standards impressed upon us throughout our careers, ABCs (Airway – Breathing – Circulation). After the maintenance of each of these has been achieved and assured, treatment of abdominal injuries can be addressed as part of the circulation assessment. Treatments should reflect a minimal on–scene time, as rapid transport of the patient to an awaiting OR is imperative. IVs should be considered en route to the ER and only run at a rate conducive to maintaining a systolic B/p of 90–100 mmHg. Other standard shock treatments should also be included during the transport. Since specific injury diagnosis is practically impossible in the pre–hospital setting, early recognition of a possible problem is the key to the proper management of the abdominal trauma victim. Rapid transport of all suspected abdominal injuries is imperative when you consider that no other area of the body is capable of readily hiding such large quantities of blood. Quick recognition and rapid treatments en route help to keep us “ahead of the game,” especially when considering that patients with serious intra–abdominal injuries can easily deteriorate rapidly and often without warning. TRAUMA ABDOMINAL TRAUMA Abdominal trauma is typically a difficult at best situation to assess especially in the pre–hospital setting. As with any traumatic incident, injury is delineated into two categories; blunt trauma and penetrating trauma. Penetrating trauma is obviously easy to recognize, as the integrity of the abdominal wall has been breeched. Blunt trauma on the other hand, can be subtle, which allows for the pre–hospital provider to possibly miss underlying injuries. Whether the mechanism of injury is blunt or penetrating, the two most life– threatening problems associated with abdominal trauma are hemorrhage and infection. The key to proper management of the abdominal trauma patient is rapid assessment and recognition, and proper shock management. Assessment of the traumatic abdomen causes us to remember our anatomy of the three regions within the abdomen; thoracic abdomen, true abdomen, and retroperitoneal abdomen. Each region houses both solid and hollow organs within which represent different injury patterns accordingly. The thoracic abdomen is considered to encompass all the organs which reside in the abdomen, yet are still protected anteriorly by the inferior portion of the rib cage (i.e. spleen, liver, gallbladder, stomach). Special consideration must be given, as rapid hemorrhage is very possible with injuries here. Even minor lacerations to liver or spleen can cause significant blood loss, resulting in a “shocky” patient. The true abdomen encompasses the large and small intestines, and the bladder. One also must incorporate the anatomy of the female patient since the true abdomen also holds the ovaries, uterus, and fallopian tubes. Injury to these organs typically cause infection, peritonitis, and occasionally shock (especially in females due to the vascularity of the uterus ). Finally, the retroperitoneal region lies posterior to both the thoracic and true abdomens. This region is the most difficult to assess due to its location anatomically. Organs located within this region include; kidneys, pancreas, abdominal aorta, and the inferior vena cava. Each of these present a large opportunity for massive hemorrhage with the possibility of no obvious changes to the region, so it is imperative that other signs and symptoms of shock are observed for. Proper assessment of the abdomen typically revolves BURNS Each year approximately 2 million people are burned in the United States resulting in approximately 12,000 deaths. As a result, many of the survivors of these incidents are unfortunately severely disabled and/or disfigured. Burns are classified by the cause, and, more importantly, severity, or degrees, E - 63 2/15/06 EMERGENCY MEDICAL GUIDELINES which depends upon the depth of the burn. Each burn creates a unique set of management problems while at the same time, each burn management case will follow the same treatment modalities. Burns are typically classified into one of the following causes: flame, electrical, chemical, radiation, steam, or scald. The skin, the largest organ in the human body, is the predominant reference made when talking about burns. However, its importance in temperature regulation, environmental protections, and other homeostatic functions is unsurpassed. Unfortunately, even though the skin is often the only place you actually see the effects of burns, it is the underlying structures, organs, and vessels which are the ultimate considerations treating a burn patient. The skin is divided into two layers: the epidermis, the thin outer layer seen on the surface, and the dermis, the thick connective tissue layer located just beneath the epidermis. Burns degrees are based upon the amount of tissue involvement as it pertains to the skin. First–degree burns typically involve just the outer regions of the epidermis and are commonly recognized by their red, painful skin, which usually heals within 3 to 6 days following the incident. Second– degree burns (commonly referred to as partial thickness burns) involve deeper regions of the skin including all of the epidermis and typically just the outer regions of the dermal layer. Second–degree burns are commonly seen as red, blistered skin that is very painful to touch and will typically heal within 2 to 4 weeks after the exposure. Finally, third–degree burns, which are considered the most dangerous. These are referred to as “full–thickness” burns due to the fact that all layers of the skin, including the underlying subcutaneous tissues and muscle layers are commonly involved in the burn–damaged area. Third–degree burns are commonly characterized by the white–gray, leathery, charred skin that is void of pain due to the complete destruction of the nerve endings located within that region of the skin. Third degree burns do not heal naturally due to the complete destruction of all the skin cells located within the area and long– term treatment typically includes skin grafts. Assessment of the burn patient encompasses the size and location of the affected area, as well as the cause of the burn itself, and, most importantly, the safety of the crew and patient. Scene safety must always be in the forefront of everyone’s thoughts when on any trauma call. Assessment of the burn patient follows the ABCs as we have all been taught, although special consideration must be made with regards to airway control. Inhalation burns, which account for more than half of all burn deaths, commonly cause E - 64 2/15/06 edema and swelling to the upper airways. This ultimately leads to the “closing off” of the airway. Early recognition of such a possibility must be considered and acted upon prior to the complete closure of the airway. Aggressive airway management will ultimately determine the viability of your patient. Determining the cause of the burn is also of great importance. Although flame exposure, chemical, and scald burns are easily recognizable on the surface, electrical burns may only manifest themselves as a small dot or circle on the skin, yet the damage created from the burn can be staggeringly more severe. One also must also consider the size of the affected area. The common “Rules of Nine” chart allows pre–hospital providers to approximate the percentage area affected by the burns, but this does not account for the possible areas affected when considering an electrical burn. One must believe that all areas between an entrance–burn and an exit–burn are also affected. This can drastically increase the size of your burn. One must also note the area affected by the burns. Face, hands, feet, genitals, and major joints are areas that require special attention by properly trained burn specialists. Special considerations for chemical burns are required, in such that even though you may have an easily recognizable outer burn area, you have to determine whether or not the skin has absorbed the chemical agent and is now possibly circulating it systemically. Management of the burn patient depends upon the cause and region of the burn. As a pre–hospital provider, you must realize that burn patients do not typically die rapidly from the burns themselves, rather, they die from the secondary conditions related to the burns (i.e. airway obstruction secondary to edema from an inhalation burn). Management should place the greatest emphasis on airway management and the removal of the patient from the source of the burn. Cooling of the burn site should be limited as to prevent the accidental causing of hypothermia or localized vasoconstriction. This would decrease the blood flow to an already damaged region. The long–term prognosis of the patient is increased when recognition for rapid transport is made. To minimize infection and other long–term considerations for the patient, pay attention to wound care. Remember, the most important thing you can do for your burn patient is airway management. CHEST INJURY Chest injury is often a deceptive diagnosis without the availability of X–rays. Any chest wall injury associated with difficulty breathing should be considered serious until proven otherwise. Chest injuries are the second leading cause of trauma related deaths each year. A thorough assessment is EDUCATIONAL GUIDELINES essential, as missed injuries can lead to impaired ventilation causing hypoxia, hypercarbia, and acidosis. The major types of chest injury are listed below. Rib Fractures, Flail chest, Pulmonary contusion Pneumothorax (open and closed), Tension Pneumothorax and hemothorax, Myocardial Contusion, Pericardial tamponade, Aortic, tracheal, and bronchial rupture, Traumatic asphyxia, Penetration and compromise of the diaphragm. The above can be caused by a variety of trauma: Motor Vehicle accidents, falls, sports injuries, crush injuries, stab wounds, and gunshot wounds. The goal in the treatment of these injuries is to maintain the patients ability to oxygenate blood passing through the lungs. Provide supplemental High Flow Oxygen, do a thorough assessment, and treat the injury following the appropriate procedural guideline. Chest injury may be penetrating or blunt. Penetrating injuries are caused by forces distributed over a small area as in gunshot wound, stabbing, or falls onto sharp objects. With penetrating trauma, any structure or organ in the chest cavity may be injured. With blunt trauma, the forces are distributed over a larger area, and many injuries occur from deceleration, bursting, and shearing forces. Conditions such as pneumothorax, pericardial tamponade, flail chest, pulmonary contusion, and aortic rupture should be suspected in blunt trauma or when the mechanism of injury involves rapid deceleration. Symptoms The symptoms of chest trauma include; shortness of breath, tachypnea, and chest pain. The pain is usually pleuritic, pain upon movement of the chest wall during respiration. The patient will usually try to splint the chest wall thereby limiting the movement during respiration. Conditions such as pneumothorax, and vascular injuries might not produce any symptoms initially. Repeat assessment is essential. Signs The evaluation of the chest should include observation, palpation, and auscultation. Signs to observe include, cyanosis, bruises, lacerations, puncture wounds, jugular vein distention, tracheal deviation, subcutaneous emphysema, and asymmetrical chest rise. The neck and chest should be palpated for the presence of tenderness, bony crepitus, subcutaneous emphysema, and an unstable chest segment. The chest should be auscultated for equal lung sounds, volume of inspiration, and diminished or absent breath sounds on one or both sides of the chest. Signs and Symptoms of Specific Injuries Rib Fractures: Pain on inspiration, local tenderness, bony crepitus. Flail Chest: Paradoxical Chest movement, pain, crepitus, hypoxia. Pulmonary Contusion: Usually seen with flail segment, pain, hypoventilation, hypoxia. Pneumothorax: Unequal lung sounds, difficulty breathing, tachypnea, pleuritic chest pain. Open Pneumothorax: Pain, difficulty breathing, bubbling sound as air moves in and out of the pleural space through the defect. Tension Pneumothorax: Pain, difficulty breathing, jugular vein distention, tracheal deviation, absent or diminished lung sounds, cyanosis, tachycardia, narrow pulse pressure. Hemothorax: Tachypnea, decreased breath sounds, dullness to percussion, clinical signs of Shock, difficulty breathing. Myocardial Contusion: May have no signs and symptoms other than chest pain from striking object. Arrhythmias are to be treated by ACLS protocol be alert to mechanism of injury. Pericardial Tamponade: Tachycardia, jugular vein distention, narrow pulse pressure, Pulsus Paridoxus (can be determined by noting the radial pulse diminish or even disappear with inspiration), muffled heart sounds. Aortic Rupture: Clinical signs of Shock, unequal pulses between the arms and the lower torso. (Radial and Femoral Pulses) Tracheal/Bronchial Rupture: Severe dyspnea, hemoptysis, subcutaneous emphysema. Traumatic Asphyxiation: Bluish discoloration to face and neck, jugular vein distention, conjunctival hemorrhage, difficulty breathing. Diaphragmatic Rupture: Difficult to diagnose, decreased breath sounds particularly over the left chest, sometimes bowel sounds may be heard in the left chest. If a considerable amount of abdominal contents is displaced into the chest, the abdomen may have a hollow or empty appearance. In summary serious injury to the chest can disrupt ventilation and also cause profound circulatory compromise. Maintaining the ABC’s as well as quick assessment and intervention for field treatable injuries (i.e.. Tension Pneumo, Pericardial Tamponade, Sucking Chest wound, Flail Chest) can be lifesaving. Interventions should be done enroute to the hospital if possible, as on scene times should be kept to a minimum for these trauma patients. E - 65 2/15/06 EMERGENCY MEDICAL GUIDELINES neck, and upper chest, but not below the nipple line. Associated injuries may require intubation and mechanical ventilation. All survivors in a large series were extricated within fifteen minutes of intrapment. Patient’s who survive for more than an hour will uniformly do well with 90+% chance of survival without sequelae or complications. CRUSH INJURY Crush injuries and their secondary metabolic complications are relatively uncommon, but are a significant form of trauma. The three major syndromes associated with crushing injuries are: Crush Syndrome Compartment Syndrome Traumatic Asphyxia These complex and often devastating injuries are among the most challenging types of trauma encountered by pre– hospital care providers. Early recognition and prompt therapy are essential to achieving a favorable outcome, whereas delays in diagnosis and treatment may result in permanent and severe disability. DROWNING/NEAR DROWNING Bystander CPR may be in progress. The Team should prepare for abdominal distention with vomiting. Focus on airway management and hyperventilation, with compressions if appropriate. A significant amount of drowning victims develop marked laryngospasm with airway occlusion. The Team should consider the following: head or spinal injury, aspiration of fluid, lung sounds, down time and water temperature. Near–drowning victims, because of aspiration or laryngospasm, usually sustain significant hypoxemia, with the consequent danger of respiratory failure and hypercapnia. Acute reflex laryngospasm may result in asphyxia without aspiration of water. Aspiration of fluid and particulate matter may cause chemical pneumonitis, damaging cells lining the alveoli, and may impair alveolar secretion of surfactant, resulting in patchy atelectasis. The perfusion of non–aerated, atelectatic areas of the lungs leads to intrapulmonary shunting of blood and aggravates hypoxemia; the more fluid aspirated, the greater the surfactant loss, atelectasis, and hypoxemia. Aspiration of large quantities of water may cause sizable areas of atelectasis, resulting in stiff noncompliant lungs and respiratory failure. Respiratory acidosis with hypercapnia and hypoxemia can occur. A concomitant metabolic acidosis may also result from tissue hypoxia. Hypoxemia and tissue hypoxia often result in pulmonary edema and even cerebral edema. The mammalian diving reflex in cold water allows survival after long periods of submersion. The diving reflex, first identified in seagoing mammals, slows the heartbeat and constricts the peripheral arteries, shunting oxygenated blood away from the extremities and the gut to the heart and brain. In cold water, the O2 needs of the tissues are reduced, extending the possible time of survival. Respiratory insufficiency is more critical than changes in electrolytes and blood volume, which vary in magnitude depending on the type and volume of aspirated fluid. Sea water may cause a mild elevation of sodium and Cl, but the levels are rarely life–threatening. By contrast, aspirating large quantities of fresh water can cause a sudden increase in blood volume, profound electrolyte imbalance, and hemolysis. Victims may succumb to the effects of these changes – asphyxia and possibly ventricular fibrillation – at the scene of the tragedy. Cardiac arrest, usually preceded by fibrillation, causes CRUSH SYNDROME: Following extrication, the patient frequently feels relatively little or no pain, and may have few physical complaints. Instead, emotional complaints dominate the history, as might be expected from a patient trapped or buried for hours. Multiple skin lacerations and tears are common when a direct pressure trauma occurs, such as when a car runs over an extremity. If crush syndrome develops and is untreated, Hypovolemic shock and hyperkalemia occur, followed by acidosis and acute renal failure secondary to myoglobin released from damaged tissue. COMPARTMENT SYNDROME: Compartment syndrome is caused by higher than normal pressure within a closed space, usually a muscle compartment. It occurs secondary to either a decrease in compartment size or an increase in compartment contents. The pathophysiology of compartment syndrome essentially results from too much volume in too little space leading to too much pressure. As perfusion is impaired, ischemia and tissue edema occur and are followed by more swelling. Tissue ischemia is followed by tissue necrosis. Muscle death may result in myoglobinuria, acidosis, and renal failure as well as amputation of the involved extremity, sepsis, or sepsis, or death. TRAUMATIC ASPHYXIA: Traumatic asphyxia, usually resulting from injuries that cause direct chest compression are rare. The exact pathology of this syndrome is unknown…one hypothesis is that blood forced out of the right atrium by the crushing force moves through the innominate and jugular veins toward the head. The clinical syndrome includes subjuctival and subcutaneous hemorrhages, bluish discoloration of the face, neck, and pronounced facial edema. Peleckiae is evident at the face, E - 66 2/15/06 EDUCATIONAL GUIDELINES many of the deaths attributed to drowning. However, current belief is that the pulmonary edema following near– drowning is a direct result of hypoxemia and analogous to pulmonary edema of high altitude, i.e., noncardiogenic pulmonary edema. Time should not be wasted in attempts to drain water from the lungs in a freshwater victim, because the hypotonic fluid passes rapidly into the circulation. Sea water, being hypertonic, draws plasma into the lung, and the Trendelenburg position may promote drainage. Hospitalization is mandatory for all victims. Resuscitation should continue during transport, regardless of the patient’s condition. Consciousness is not synonymous with recovery, since delayed death from hypoxia can occur. iris, cataract, dislocated lens, glaucoma, vitreous hemorrhage, orbital–floor fractures, retinal hemorrhage or detachment, and rupture of the eyeball may result. Emergency treatment may be needed before care by a specialist. It consists of alleviating pain and applying protective dressings. Traumatized lids should never be opened forcibly, since this could aggravate the injury. Rarely, after a laceration of the globe, the uninjured, contralateral eye becomes inflamed (sympathetic ophthalmia) and may lose vision to the point of blindness. Anterior chamber hemorrhage (traumatic hyphema) following blunt injury is potentially serious and requires attention by an ophthalmologist. It may be followed by recurrent bleeding, glaucoma, and blood–staining of the cornea. Although initially retinal detachment may be localized, without treatment the entire retina may detach. Rhegmatogenous detachment implies a break through and through in the retina and is seen more frequently in myopia, after cataract surgery, or following ocular trauma. Non– rhegmatogenous detachments can be produced by vitreoretinal traction (i.e. proliferative retinopathy of diabetes or sickle cell disease) or by transudation of fluid into the subretinal space (i.e., severe uveitis, especially in Vogt– Koyanagi–Harada disease, or primary or metastatic choroidal tumors). Retinal detachment is painless. Premonitory symptoms may include dark or irregular vitreous floaters, flashes of light, or blurred vision. As the detachment progresses, the patient notices a curtain or veil in the field of vision. If the macula is involved, central visual acuity fails drastically. Any patient with a suspected or established retinal detachment should be seen, on an urgent basis, by an ophthalmologist. Direct ophthalmoscopy may show retinal irregularities and a bullous retinal elevation with darkened blood vessels. Indirect ophthalmoscopy, including scleral depression, is necessary to detect peripheral breaks and detachment. If a vitreous hemorrhage obscures the fundus, especially in myopia, post–cataract extraction, or eye injury, retinal detachment should be suspected and ultrasonography performed. Subconjunctival hemorrhages may develop at any age, usually following minor trauma, straining, sneezing, or coughing; rarely, they occur spontaneously. They alarm the patient but are of no pathologic significance except when associated with blood dyscrasias, which is rare. They occur as gross extravasations of blood beneath the conjunctiva and are absorbed spontaneously, usually within two weeks with treatment. Vitreous hemorrhages, extravasations of blood into the vitreous, produce a black reflex on ophthalmoscopy. They may E - 67 2/15/06 EYE INJURIES The three principal types of eye injuries encountered by the Team are due to blunt and penetrating trauma, burns and foreign bodies (including chemicals). Chemical injury generally requires the fastest action to avoid permanent damage. Most of the field treatment of eye injuries involves only superficial care, since the majority of problems must be handled in the hospital by an opthamologist. Sudden loss of vision in one eye can be caused by thrombosis or occlusion of the retinal artery. Acute glaucoma produces pain, headache, nausea and haloes around the eye. Treatment is patching. Retinal detachment causes vision loss, flashing lights, and dark spots. Treatment is transport in supine position and patch both eyes. Trauma to the eye or adjacent structures requires meticulous examination to determine the extent of injury. Vision, range of extraocular motion, depth of anterior chamber, location of lid and conjunctival lacerations and of foreign bodies, and presence of anterior chamber or vitreous hemorrhage or cataract should be determined and recorded in detail for protection of patient, physician, and in industrial cases, employer. 1. Conjunctival and corneal foreign body injuries are the most common eye injuries. Seemingly minor trauma can be serious if ocular penetration is unrecognized or if secondary infection follows a corneal abrasion. 2. Intraoccular foreign body injuries require immediate emergency treatment, and the foreign body that has penetrated the eye must be removed by an ophthalmic surgeon. A patch and a metal shield are placed over the eye to avoid inadvertent pressure that could extrude ocular contents through the penetration site. The patient should not receive anything by mouth in preparation for urgent surgery. Trauma to the globe may severely damage internal structures. Hemorrhage into the anterior chamber, laceration of the EMERGENCY MEDICAL GUIDELINES occur in such conditions as diabetic retinopathy or hypertension or may result from trauma, retinal neovascularization, or retinal tears. Retinal hemorrhages are flame–shaped in the superficial nerve fiber layer, as in hypertension or venous occlusion, or round (dot and blot) in the deeper layers, as in diabetes mellitus or septic infarctions. Retinal hemorrhages are always significant, reflecting vascular disease that usually is systemic. Seeing floaters (spots) before one or both eyes is a frequent adult complaint. Floaters are usually most noticeable against a white homogeneous background and seem to move slowly. They result from contraction of the vitreous gel and its separation from the surface of the retina. Since the vitreous gel is denser where it attaches to the optic nerve, floaters are usually more apparent in this area. Though floaters usually are without significance, in a small number of patients they may indicate a tear in the retina. They are more prevalent in highly myopic and older persons, tending to become less noticeable with time. A minute vitreous hemorrhage may appear as a brown or red floater. Retinal detachments may be preceded by a shower of “sparks”or lightning flashes and may be accompanied by a shower of floaters. Only after the retina actually separates from its underlying structure (the retinal pigment epithelium) does a “curtain” of visual loss move across the visual field. Abnormal visual intolerance to light is common in lightly pigmented persons. Usually it is without significance and may be relieved by wearing dark glasses. It is an important, but nondiagnostic, symptom in keratitis, uveitis, acute glaucoma, and traumatic corneal epithelial abrasions. Ocular pain is important and, unless due to an obvious local cause such as a foreign body, acute lid infection, or injury, demands investigation (i.e., for uveitis, especially iridocyclitis, or glaucoma). Sinusitis occasionally causes referred eye pain. A blind spot in the field of vision is a negative scotoma. Frequently it is not noticed by the patient unless it involves central vision and interferes significantly with visual acuity. Negative scotomas noticed by the patient usually are due to hemorrhage or choroiditis. A scotoma found in the same visual field area in each eye is usually a quadrantic or hemianoptic defect resulting from a lesion in the optic pathways. A positive scotoma, perceived as a light spot or scintillating flashes, represents a response to abnormal stimulation of some portion of the visual system; i.e., as in the migraine syndrome. as simple injuries (splinting, elevation and ice). Treat long bone fractures, hip, pelvic or spinal injuries as major trauma. When the patient’s condition and time permits, the Team should establish IV and EKG monitoring prior to moving patient. The Team should consider the following: shock, assessment of painful areas, sensation and circulation tested before and after splinting and/or manipulation. Any complaint of paresthesia, weakness of motor function, diving or body surfing injuries should be treated as a spinal injury. Assess long bone fractures noting pulse and sensation. If a fractured limb is ischemic or cannot be stabilized because of deformity, apply gentle traction along the long axis of the limb to reduce and stabilize the fracture. Recheck and record neurovascular status after each movement of limb. Use of PASG is indicated for suspected pelvic fractures. HEAD INJURIES Significant head injuries, which have associated findings of disturbed consciousness, abnormal CNS exam, or significant signs of head and neck trauma, produce some of the most critical injuries attended. Assuming greater severity of injury is prudent. Treat every significant head injury as neck injury too. The Team should consider the following: CSF leaks, seizure activity, check mouth, drugs at scene, focal findings in neurological exam or Cheyne–Stokes respirations. Nasotracheal intubation is contraindicated with severe facial injuries. Head injury causes more deaths and disability than any other neurologic cause before age 50 and is the leading cause of death in men and boys less than 35 years old. Mortality in severe injury approaches 50% and is only little reduced by treatment. Damage results from skull penetration or from rapid brain acceleration or deceleration, which injures tissue at the point of impact, at its opposite pole (contrecoup), and also diffusely within the frontal and temporal lobes. Nerve tissue, blood vessels, and meninges are sheared, torn, and ruptured, resulting in neural disruption, intra– and extracerebral ischemia or hemorrhage, and cerebral edema. Hemorrhage or edema acts as an expanding intracranial lesion, causing focal neurologic deficits or increased intracranial swelling and pressure that can lead to fatal herniation of brain tissue through the tentorium or foramen magnum. Skull fractures may lacerate meningeal arteries or large venous sinuses, producing epidural or subdural hematoma. Fractures, especially at the skull base, can also lacerate the meninges, causing CSF leakage through the nose (rhinorrhea) or ear (otorrhea), or ingress of bacteria or air into the cranial vault. Infectious organisms may reach the meninges via cryptic fractures, especially when they involve the paranasal sinuses. Few head injuries occur in isolation, and most cases require simultaneous attention to other seriously traumatized parts of the body. FRACTURES The handling of fractures may dramatically alter prognosis of the injury. Minor or small bone fractures should be treated E - 68 2/15/06 Signs of primary brainstem injury (coma. red skin. and cocaine) increase susceptibility to heat illness. heat exhaustion and heat stroke. loss of oculovestibular reflexes.

Other injuries similar to AGE & occurring on rapid ascent – Mediastinal emphysema – gas is forced into the media stinum – Pericardial emphysema – gas is forced into the pericardium and presents as pericardial tamponade. muscle. The danger is that the diver will do something foolish while under the effect of nitrogen narcosis and suffer a more serious injury. rapid ascent and or flying or traveling to high altitudes within 24 hours after diving. – Patients may present with shortness of breath (chokes). The increased partial pressure of O2 at depth combined with the increased percentage of O2 results in oxygen toxicity at shallower depths . resulting in an increased bottom time. – Other important information to gather includes any history of recent upper respiratory infections. ear pain.72 2/15/06 because they often present with altered mental status or in shock. Divers should be questioned as to the method of computing bottom and ascent times with safety stops. NITROGEN NARCOSIS (RAPTURE OF THE DEEP) Nitrogen Narcosis is caused by an over–saturation of nitrogen in the bloodstream through an unknown process. 32% and 36% O2 are common mixes. Decompression sickness type I patients often have a history of recent diving followed by a flight home. and shock. or back pain that worsens over time. – Essential history to ascertain includes time since dive ended. OXYGEN TOXICITY Oxygen toxicity has rarely been seen in the past when dealing with recreational divers diving within accepted limits (less than 130 ft). There is a trade–off here and that is increased risk of oxygen toxicity.EMERGENCY MEDICAL GUIDELINES oral pain. The dive profile consists of prior dives that day. As the diver ascends the trapped air expands. – Inquires should be made specifically about previous decompression ~ injuries. altered mental status. They also may complain of dizziness or weakness. Pain is reported in only about 30% of cases. severe headache. usually within minutes of surfacing. With the increase in oxygen the percentage of nitrogen decreases. These patients often die before reaching medical facilities. Pain may range from mild t9 severe (the bends). The shoulder is the most commonly affected joint. and suddenly screaming and losing consciousness. EAN is essentially air with an increased O2 percentage.

Patients may rapidly deteriorate without emergent intervention. identification of this characteristic should be undertaken carefully. PNEUMOTHORAX Injury occurs similar to an AGE however the gas becomes trapped within the pleural space. usually around the neck and collarbones. it is believed to be somewhere between 50 and 100. children and infants being more vulnerable. The condition of the victim will seriously affect the outcome. and alert snake is deadlier. Depending on the mixture oxygen toxicity can occur in water between 90 and 100 ft. shy snake with a rather distinct pattern of red and black bands that are wider than the interspaced yellow rings. The early signs of a coral snake bite are slurred speech. This condition is similar to pericardial tamponade. The diver who is now at a normal ambient pressure will no longer be suffering from oxygen toxicity and may be treated accordingly. and so is its depth and the duration of the time of penetration of one or more fangs. There are three additional characteristics of pit vipers that aid in distinguishing them from harmless snakes. Hypertension. Palpation of the area can produce the effect of “Rice Crispies” under the skin. First. As the diver ascends the trapped air expands. Second. the treatment is fairly standard. quantity. the scales are arranged in double rows from the anal plate to the tip of the tail. restricting the pumping action of the heart.

The examination consists of assessing pupil size. the pupillary light reflex is an indirect measure of herniation or brainstem injury. hypotension. GCS scoring should occur after hypoxemia and hypotension are corrected and the patient has been resuscitated. and hypothermia are also associated with dilated pupil size and abnormal reactivity. A patent airway should be ensured and endotracheal intubation performed for patients with a GCS score less than 9 or those who are unable to maintain or protect their airway. or after these drugs have been metabolized. No studies prove the efficacy of mannitol in the pre–hospital setting. along with the GCS score.

All other treatments should be performed following the appropriate guidelines. Inter–hospital transfers of these head injury patients are known to delay the time until neurosurgical consultation and intervention. Patient treatment/transport should not be delayed for wound care in life–threatening situations. When an integrated EMS and trauma system is in place and EMS agencies transport a patient directly fro the scene of the accident to an appropriate receiving facility (trauma center).

If there is no peripheral pulse. children are somewhat less likely to have dangerous transmissible diseases and the number of children satisfying the criteria for a ventilatory trial will be relatively small. Crosscontamination is a minimal issue. secondary triage should consist of the RPM components of the JumpSTART algorithm. NOTE: Children with special health care needs are often chronically unable to ambulate.. the patient is tagged as deceased (black ribbon) and the triage officer moves on.e. although those with chronic respiratory problems may routinely have elevated respiratory rates. If the patient resumes spontaneous respirations. infants may be triaged to the minor category. If they satisfy all of the physiologic “delayed” criteria (i. using the JumpSTART algorithm. This is the pediatric “jumpstart”. the patient is tagged as immediate and the triage officer moves on without providing further ventilations. the rescuer palpates for a peripheral pulse (radial. If the ventilatory trial fails to trigger spontaneous respirations. A caregiver with knowledge of the children involved would be of invaluable assistance in this case. Also. Step 2A Nonambulatory pediatric patients are initially assessed for presence/absence of spontaneous breathing. where they will undergo secondary (more involved) triage. There is a trend favoring brief medical data cards to be stored in the driver’s area of buses and other vehicles routinely transporting children with special health care needs.

(An adult mask may be used for a child if inverted. These children can be triaged similar to infants who are developmentally unable to walk. usually in the secondary triage stage. the patient is triaged in the delayed category (yellow ribbon). This has been substituted for capillary refill (CR) because of the variation in CR with body and environmental temperature and because it is a tactile technique more adaptable to poor environmental conditions. If there are no peripheral pulses. The rescuer now performs a rapid “AVPU” assessment. or responds appropriately to pain (localizes stimulus and withdraws or pushes it away). If there are palpable peripheral pulses. If the child does not respond to voice and responds inappropriately to pain (only makes a noise or moves in a nonlocalizing fashion). If the patient is alert.

Complete paralysis is obtained within 1 minute and persists for approximately 2 minutes. It has no effects on consciousness whatsoever. INDICATIONS To facilitate intubation in patients where other efforts to obtain definitive airway control have failed. CONTRAINDICATIONS Any patients who can not be effectively ventilated with a BVM and oral airway. SIDE EFFECTS Prolonged apnea, bronchospasm, sinus arrest, tachycardia, bradycardia, PVC’s, increased ICP, muscle fasciculations. SPECIAL CONSIDERATIONS Since Succinylcholine Chloride effects only skeletal movement and not sensation, the patient should be sedated prior to administration. The use of Succinylcholine will not reduce the patients level of consciousness. The paramedic should verbally reassure the patient before intubation. If unable to intubate the patient, ventilate with BVM and oral airway until spontaneous respirations return (this should occur in approximately 5 to 7 minutes). Less than one percent of the population, and a higher percentage of the pregnant population, lack sufficient pseudocholinesterase to rapidly metabolize Succinylocholine.

INDICATIONS Long term paralysis for flight or ground transport to facilitate control of combative patients that have already been intubated. CONTRAINDICATIONS Any patient that an RSI has NOT been successful. SIDE EFFECTS Prolonged apnea, tachycardia, bradycardia, bronchospasm, muscle fasciculations. SPECIAL CONSIDERATIONS If Succinylcholine is used prior to Norcuron, the administration of Norcuron should be delayed until the patient starts recovering from the Succinylcholine-induced neuromuscular blockade. Prior administration of Succinylcholine may enhance the neuromuscular blocking effect of Norcuron and its duration of action. The effect of prior use of other nondepolarizing neuromuscular blocking agents on the activity ofNorcuron has not been studied. Norcuron should only be given to a pregnant woman if clearly needed. DOSAGE Adult: Initial dose: 0.1 mg/kg IVP Maintenance dose: 0.015 mg/kg IVP (25 – 40 min. after initial dose) Subsequent maintenance doses, if required, may be administered at 12 – 15 minute intervals.

In the vast majority of cases. paramedics or other rescue health workers in the field. or for decontamination of protective equipment. and hospital emergency department physicians and nurses.Emergency Medical Guidelines respond in a defensive fashion without actually trying to stop the release from a safe distance. However. decontaminate victims or response personnel. The protocols are intended as guidelines.” ~. “First responders at the operations level are individuals who respond to releases or potential releases of hazardous substances. and that their personnel are trained to follow it. We have evaluated the rule and recommend no less than four hours of training as being sufficient to meet the OSHA requirements for this category of responder. for controlling and containing the release. as part of the initial response to the site for the purpose of protecting nearby persons. Controversies abound in the evolving field of environmental toxicology. Given their typical daily responsibilities and training. and responsibilities at a haz-mat spill site (particularly if they are not part of the fire service) they should be trained at least at the “First Responder Awareness Level”. They may require modification depending on the resources of a particular department or the needs of a particular patient.120 regulations state that EMT’s and Paramedics cannot wear special protective gear. additional medical training to decontaminate and manage victims would probably be necessary. The federal rule does not specify how many hours of training are necessary for this level. These protocols are designed for use by Haz-Mat entry team members. Given EMS personnel’s medical duties. It is essential for the safety of health care personnel and patients that hospitals and emergency medical services agencies have a written plan for management of the contaminated victim. Again. “First responders at the awareness level are individuals who are likely to witness or discover a hazardous substance release and who have been trained to initiate an emergency response by notifying the proper authorities of the release.

HAZARDOUS MATERIALS MEDICAL MANAGEMENT PROTOCOLS INTRODUCTION The NIOSH EPA hazardous waste site operations document is helpful in defining the EMT / Paramedic’s role. The following treatment protocols provide step–by–step information on how to manage medical problems arising from the most common kinds of hazardous materials (“haz-mat”) scenes. no consensus exists on what specific protective gear. Again. Sixteen hours of training is required for this level by Federal OSHA mandates. All of this must be consistent with the haz-mat role that the local EMS agency has defined for EMS personnel. property or the environment from the effect of the release. it is prudent for providers to don the protective gear when appropriate. and telephone numbers of all personnel and victims who have been or may have been exposed at a haz-mat scene should be recorded for future notification if it is subsequently determined that medical evaluation or treatment is required. Refer to your local EMS agency medical director for guidance. If there is any doubt about the potential for secondary contamination. If victims are already properly decontaminated before they are brought to health care providers at the perimeter of the hot zone/decon area. pre–hospital health care personnel may need to repeat or continue decontamination procedures (e. patients with serious trauma or medical illness can be quickly stripped and flushed with water prior to delivery to pre–hospital health providers outside the hot zone. advance arrangements for additional training and protective equipment should be made. Consult the lists above or knowledgeable sources to determine the risk of secondary contamination. In those rare circumstances where they have been in the hot zone or have attended to a victim who was not properly decontaminated. Many toxic substances have delayed onset effects. However. obtain consultation from the Regional Poison Control Center to determine if delayed effects might be seen and for guidance on triage of asymptomatic or mildly symptomatic exposure victims. Note that some of the management protocols may exceed the paramedic scope of practice in a local area. which may appear several hours later. advice from the local environmental health department.

A contaminated appendage can be washed without wetting the whole body if that is the only part contaminated. if not most cases. health care providers will not generally need to use any specialized protective gear. after the victim has returned home. every effort should be made to decontaminate the victim at the scene if the means to do so are available. and dispose of or clean contaminated clothing and personal items.
