Background: One of the 2010 Impact Goals of the Emergency Cardiac Care (ECC) Committee of the American Heart Association is to double survival from cardiac arrest. Currently, approximately 60% of adults and 50% of paediatric patients that regain spontaneous circulation following cardiac arrest die before leaving the hospital. A key piece of the "chain of survival" is this fifth link; the care of patients post-arrest. Although there are several modalities recommended for post arrest care, therapeutic hypothermia is the only in-hospital therapy that has been demonstrated in randomized clinical trials to improve patient outcome after cardiac arrest. Despite the strong evidence for its efficacy and the apparent simplicity of this intervention, recent surveys show that hypothermia is delivered inconsistently, incompletely, and with undue delay in hospitals receiving resuscitated patients; only 26% of physicians and 26% of hospitals regularly institute a hypothermia protocol.
