Hypothermia.

Significant hypothermia is an increasing clinical problem that requires a rapid response with properly trained personnel and techniques. Although the clinical presentation may be such that the victim appears dead, aggressive management may allow successful resuscitation in many instances. Initial management should include CPR if the victim is not breathing or is pulseless. Further core heat loss should be prevented by removing wet garments, insulating the victim, and ventilating with warm humidified air/oxygen to help stabilize core temperature. Core temperature and cardiac rhythm should be monitored in the prehospital setting, if possible, and CPR should be continued during transport. In-hospital management should consist of rapid core rewarming in the severely hypothermic victim with heated humidified oxygen, centrally administered warm IV fluids (43 C), and peritoneal dialysis until extracorporeal rewarming can be accomplished. Postresuscitation complications should be monitored; they include pneumonia, pulmonary edema, cardiac arrhythmias, myoglobinuria, disseminated intravascular thrombosis, and seizures. The decision to terminate resuscitative efforts must be individualized by the physician in charge.
