Neurologic recovery from profound accidental hypothermia after 5 hours of cardiopulmonary resuscitation.

OBJECTIVE: To describe the successful neurologic recovery from profound accidental hypothermia with cardiac arrest despite the longest reported duration of cardiopulmonary resuscitation.

DESIGN: Case report.

SETTING: Mountain.

PATIENT: A 57-year-old woman experienced profound accidental hypothermia (16.9°C) in a mountainous region of Grenoble. She was unconscious and had extreme bradycardia (6 beats/min) at presentation. A cardiac arrest occurred at the mobilization that was not responsive to electrical shocks or epinephrine.

INTERVENTION: Cardiopulmonary resuscitation was continued for 307 minutes after rescue until venoarterial extracorporeal membrane oxygenation blood flow had been established at the emergency department.

MEASUREMENTS AND MAIN RESULTS: At a 3-month follow-up, the patient showed good physical and mental recovery.

CONCLUSION: With no evidence of trauma or asphyxia, profound accidental hypothermia with cardiac arrest represents a specific condition for which successful neurologic recovery is feasible despite prolonged cardiopulmonary resuscitation.
