Hypotension
Usually responds to small fluid bolus (500cc) and body cooling
If no response to fluids → consider vasopressors (dopamine or dobutamine)
Avoid peripheral vasoconstriction (e.g. norepinephrine), which may redirect blood flow away from skin and diminish cooling
Electrolyte abnormalities
Variable: hypokalemia and hyper or hyponatremia may be seen
Hematologic - DIC or abnormal bleeding
Hepatic injury - almost always reversible
Renal failure
ARDS
Seizure - treat with Benzodiazepines
Neurologic deficit
Persistent in 20%, associated with high mortality
