Two controlled randomized trials have shown that mild systemic hypothermia after cardiac arrest is beneficial for neurological outcome and one of the studies shows an improved survival rate. A pilot study was performed to evaluate a model of induced hypothermia after cardiac arrest, using cold intravenous fluids and surface cooling with a cold helmet and a coldwater blanket (Thermowrap). The main purpose was to evaluate our cooling method regarding efficacy, safety and usability. ⋯ There were no adverse events during treatment. We conclude that our method is reasonably fast compared to other published methods, it is easy to perform and it offers a good temperature control during cooling and rewarming. Routines for evaluating prognosis and neurological outcome after cardiac arrest and hypothermia treatment need to be revised.

Sudden, unexpected cardiac arrest is a common cause of death. Among patients who are successfully resuscitated, a majority dies without regaining consciousness. ⋯ In this review we discuss the theoretical background of hypothermic neuroprotection and therapeutic implications. We propose that victims of cardiac arrest with return of spontaneous circulation and persistent unconsciousness are considered for hypothermia treatment and that data from treated patients are collected in a common website database (see: www.scctg.org) to allow further evaluation of the use of ICU resources, efficacy of hypothermia treatment and potential risks.
