The use of IH for 24 hours in patients who remain comatose following resuscitation from out-of-hospital cardiac arrest improves outcomes. How-ever, the induction of hypothermia has several physiologic effects that need to be considered. ⋯ Hypothermia (33 degrees C) should be maintained for 24 hours, followed by rewarming over 12 hours. Particular attention must be paid to potassium and glucose levels during hypothermia.

Neuronal injury following global cerebral ischemia continues to bea central problem of patients in the postresuscitation phase following cardiocirculatory arrest. In addition to measures focusing on rapid restoration of spontaneous circulation, the most effective treatment after cardiac arrest, as shown by large randomized trials,is the use of therapeutic mild hypothermia. ⋯ At present there is no specific neuroprotective treatment available. Promising animal experimental data concerning the use of thrombolytic agents during cardiopulmonary resuscitation have led to a large European multicenter trial (TROICA trial) that will provide its data in 2006.
