Resuscitation from cardiopulmonary arrest during accidental hypothermia due to exhaustion and exposure.

A 16-year-old boy with accidental hypothermia and cardiopulmonary arrest due to exhaustion and exposure was resuscitated after warming measures -- hot wet towels, hot water bottles, and hot water enemas and gastric lavage -- had increased his rectal temperature from 25.2 to 28.0 degrees C. Despite prolonged cardiopulmonary arrest, recovery was almost complete, with no evident cerebral damage. Cardiopulmonary resuscitation procedures should not be abandoned until the body temperature is more than 30 degrees C, because the prognosis in cases of accidental hypothermia without associated disease is excellent if cardiac function can be re-established.
