Brief Summary:
ILCOR Recommendations "On the basis of the published evidence to date, the Advanced Life Support (ALS) Task Force of the International Liaison Committee on Resuscitation (ILCOR) made the following recommendations in October 2002: Unconscious adult patients with spontaneous circulation after out-of-hospital cardiac arrest should be cooled to 32°C to 34°C for 12 to 24 hours when the initial rhythm was ventricular fibrillation (VF).Such cooling may also be beneficial for other rhythms or in-hospital cardiac arrest" (Circulation. 2003;108:118-121). This study ist to investigate the efficacy of mild therapeutic hypothermia on mortality and neurological outcome in patients after in-hospital cardiac arrest.

Condition or disease Intervention/treatment Phase
Cardiac Arrest Procedure: Mild therapeutic hypothermia Not Applicable

Detailed Description:
This is a randomized controlled multicenter trial. Patients after in-hospital cardiac arrest are randomized either to standard therapy or to standard therapy in addition to mild therapeutic hypothermia. Mild therapeutic hypothermia is performed for 24 hours with a target temperature of 32-34°C. Inclusion criteria are: Adult patients which have been resuscitated after cardiac arrest in-hospital and who remain unconscious after restoration of spontanous circulation. Exclusion criteria are: severe cardiogenic shock, severe rhythm disorders, major surgery within the last 10 days, planned surgery within the next 24 hours afer resuscitation, active bleeding, suspicion od intracranial bleeding, severe infection, such as pneumonia or sepsis, a severe neurological deficit before cardiac arrest, an aquired immun deficency, pregnacy. The primary endpoint is mortality for all causes after six months. Secondary endpoints are neurological outcome after six months measured by the Glasgow-Pittsburgh Cerebral Performance scale, and in-hospital-mortality.
