Medical teams at Geisinger Medical Center successfully resuscitated an 8-year-old boy who spent at least 147 minutes submerged in a frozen pond. The child presented with asystole and a peripheral body temperature of 7 °C, the lowest ever recorded in medical literature for a surviving patient. This case challenges existing clinical assumptions about the limits of human survival during total body ischemia.

Rescuers used cardiopulmonary resuscitation during transport, but the critical intervention was venoarterial extracorporeal membrane oxygenation. This ECMO system provided artificial circulation and controlled rewarming, allowing the heart to slowly regain a sinus rhythm. Surgeons managed severe complications including pulmonary edema, coagulopathy, and necrotizing pneumonia during a prolonged hospitalization that lasted nearly two months.

Recovery required intensive neurorehabilitation to address hypoxic ischemic changes and peripheral axonal sensorimotor polyneuropathy. By the six-month mark, the patient could stand without support and ride a tricycle. These findings suggest that resuscitation efforts for pediatric hypothermia should be considered even after 2.5 hours of asystole. The case establishes a new benchmark for potential neurologic recovery after profound cold-induced arrest.
