Severe heat stroke with multiorgan failure following collapse in a sauna.

Heat stroke is characterised by hyperthermia and acute encephalopathy. We describe a rare case of classical heat stroke secondary to prolonged sauna use with multiorgan sequelae including seizures, liver injury, kidney injury, disseminated intravascular coagulation, rhabdomyolysis and type 2 myocardial infarction. The patient was treated with external cooling, intravenous fluid therapy and blood products, and made a full recovery without need for advanced organ support. We discuss the evidence base surrounding the immediate treatment of heat stroke in the emergency department.
