He was on a 3 times a week hemodialysis schedule. Routine checks prior to starting dialysis showed a weight of 74 Kg (dry weight 70 Kg), Blood pressure 160/90 mmHg, pulse rate 90/min, moderate bilateral oedema and fine bilateral basal inspiratory crackles. Blood investigations were as follows: Hb 93 g/l Platelets 300* 109/l WBC 9* 109/l Na+ 140 mmol/l K+ 5.5mmol/l Urea 32 mmol/l Creatinine 294 µmol/l Dialysis was started through an arterio-venous fistula. After 45 minutes, the patient developed nausea and sweating. Blood pressure was 100/70 mmHg and pulse rate was 105/min. Blood sugar was 6.5 mmol/l. What is the first step in management? Stop ultrafiltraion Give normal saline 200 ml (rapid infusion) Stop the dialysis machine Do an ECG and transfer to cardiac care unit Give metoclopramide The patient developed acute hypotension due to the high ultrafiltration rate of the dialysis machine. Although the amount of ultrafiltration is not mentioned in the question a candidate should always suspect this in such a scenario when the patient weight is high above his dry weight.
