Therapeutic hypothermia (TH) has been demonstrated to have beneficial effects in brain injury, cardiac arrest, perinatal asphyxia, and some cardiac and intracranial surgical procedures [1]. In 2005, the Advanced Cardiovascular Life Support and the International Liaison Committee on Resuscitation (ILCOR) guidelines recommended induced hypothermia for comatose victims of cardiac arrest [2]. The recommendations included inducing TH at 32°C to 34°C for 12 to 24 hours when the initial presenting rhythm was ventricular fibrillation (class IIA recommendation) or nonventricular fibrillation (class IIb recommendation) [3].
