Fulminant hepatic failure from heat stroke requiring liver transplantation.

A 16-year-old man developed heat stroke during football practice when the temperature was 33.8 degrees C (heat index, 44.4 degrees C). Resuscitation with ice water lavage, external cooling, and intravenous fluids was initially successful, but the patient again became obtunded. Liver chemistry tests and the prothrombin time and serum ammonia increased markedly, and rhabdomyolysis and renal failure became evident, necessitating hemodialysis. He underwent liver transplantation for fulminant hepatic failure approximately 72 hours after admission. Rhabdomyolysis with renal failure and severe electrolyte disturbances continued despite aggressive hemodialysis and the patient had a cardiopulmonary arrest and died 10 days after transplantation. This case shows that liver transplantation cannot always overcome the generalized toxic effects of heat stroke. More aggressive hemodialysis or combined liver/kidney transplantation might result in a positive outcome in selected cases.
