title: Prolonged intensive therapy after snake bite. A probable case of envenomation by the rough-scaled snake.
abstract: A case of snake-bite envenomation, probably by the rough-scaled snake (Tropidechis carinatus), in a 9-year-old boy is reported which we believe to represent the most severe and prolonged case yet of non-fatal snake-bite envenomation in a human. The initial clinical features included loss of consciousness within minutes of the bite, followed by a period of partial recovery. The child subsequently developed total body paralysis, acute renal failure, and gross rhabdomyolysis. Artificial ventilation was maintained for 10 weeks; muscle paralysis and paresis persisted for 18 weeks before neuromuscular function returned to normal. Recovery occurred in centripetal fashion, the respiratory muscles and the palatal muscles being the last to recover. Acute renal failure persisted for 18 days and was treated by peritoneal dialysis. Some beneficial effects were seen even when antivenom was given 90 hours after the bite, but gross rhabdomyolysis caused by this species is not prevented by the administration of antivenom after 60 hours. It is concluded that if life can be sustained for 10 weeks by artificial ventilation, normal intellectual and neuromuscular recovery is possible in such cases.
