AbstractThe use of extracorporeal membrane oxygenation (ECMO) in severe hypothermia associated with cardiac arrest has become a more frequent warming technique in specialized centers over the years with better survival outcomes compared to traditional rewarming methods. We show that a full recovery is possible, even after prolonged resuscitation. We report the case of a 36-year old male who survived approximately 4 hours of cardiopulmonary resuscitation following an unknown duration of asystole in the context of severe accidental hypothermia (24°C). Normal sinus rhythm was obtained using a single external electric shock during the rewarming of the patient by ECMO. After a hospital stay of 17 days, there were no neurological deficits and he achieved a full recovery. Although prolonged out-of-hospital cardiac arrest has low survival rates and asystole is not generally considered as an indication for extracorporeal cardiopulmonary resuscitation (ECCPR), associated hypothermia can be a predictor of a possible positive outcome when ECMO is used as it reduces the metabolism and protects the brain, thus leading to "miraculous" recoveries with no neurological sequelae. This case demonstrates yet again the importance of advanced rewarming techniques such as ECMO in the outcome of patients with severe accidental hypothermia, even after prolonged and refractory out-of hospital cardiac arrest and when "no-flow" time is uncertain. It also highlights the need for accidental hypothermia treatment algorithms, especially in hospitals capable of ECMO rewarming, to enable more rapid decision-making.
