Tricyclic poisoning--successful management of ventricular fibrillation following massive overdose of imipramine.
Serious complications from tricyclic antidepressant (TCA) overdose are uncommon. We present a case of massive imipramine overdose complicated by ventricular fibrillation and a prolonged period of cardiovascular collapse. A total of 400 mmol of sodium bicarbonate, 5 mg of adrenaline and 80 mg of sotalol were given during 50 minutes of cardiac arrest. The patient made a full recovery with no apparent neurological sequelae. The highest TCA plasma level we could find in the published literature was 4873 ng/ml4; our patient's peak TCA level was 6000 ng/ml. Tricyclic antidepressant overdose is a common cause of intensive care unit admission. It has a low mortality rate.
