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