title: Therapeutic Hypothermia After Cardiac Arrest.
abstract: Resuscitated cardiac arrest continues to carry a poor prognosis despite advances in medical care. One such advance, therapeutic hypothermia, is neuroprotective and has been demonstrated to improve clinical outcomes in patients who remain unresponsive despite return of spontaneous circulation after arrhythmogenic cardiac arrest. Two landmark randomized controlled trials, both reported in 2002, led to endorsements by major American and European guidelines for therapeutic hypothermia as a viable treatment option for the prevention of adverse outcomes related to anoxic encephalopathy. Since then, significant research has been conducted to better understand the optimum strategies to maximize the neuroprotective effects of hypothermia. However, dissemination of therapeutic hypothermia guideline recommendations into clinical practice has been slow and incomplete. In this review article, we discuss the historical background and physiologic rationale for therapeutic hypothermia, review the recent literature supporting this intervention, and outline practical considerations.
