Severe exposure hypothermia: a resuscitation protocol.
Although hypothermia has been described as an emergency in suspended animation, severe degrees of hypothermia mandate appropriate aggressive intervention. Because of cardiac instability with core temperature below 28 C, aggressive invasive rewarming by F-F partial bypass is often ideal in this setting. In contrast, a gentle approach in other therapeutic maneuvers is equally important to prevent iatrogenic induction of VF in nonarrested victims. If the only definite criterion for diagnosis of death in hypothermia is failure to respond to resuscitation and rewarming, successful resuscitation must carefully balance aggressive and gentle interventions. Because CPR protocols involve legal as well as medical questions, additional prospective data are especially critical for resolving controversies in the initial management of profound exposure hypothermia.
