Time-differentiated Therapeutic Hypothermia

Not Applicable

Completed

• Conditions: Out of Hospital Cardiac Arrest

• Registration Number: NCT01689077
• Lead Sponsor: University of Aarhus

Brief Summary

The purpose of this study is to determine if 48 hours of mild therapeutic hypothermia following out of hospital cardiac arrest gives a better cerebral outcome compared to 24 hours therapeutic hypothermia.

Detailed Description

Sudden out-of-hospital cardiac arrest (OOH-CA) remains a significant cause of death. However, in 2002 it was in two clinical trials demonstrated that mild therapeutic hypothermia in comatose OOH-CA victims yields a better cerebral outcome measured by Cerebral Performance Category Score (CPC) after 6 month. The optimal mild hypothermia treatment time is however not known. The two trials from 2002 apply the treatment for 12 and 24 hours respectively. In newborns with cerebral hypoxic damage the standard treatment time is 72 hours. It is therefore relevant to investigate the influence of the treatment time on the cerebral outcome in OOH-CA victims. In the present study cerebral outcome after mild therapeutic hypothermia (target temperature 33 degrees centigrade) in OOH-CA patients for 24 is compared to outcome after 48 hours of mild hypothermia. The main outcome parameter is mortality and CPC score measured 6 month after the treatment.

Primary Outcome Measures

Name	Time	Method
CPC	6 month	CPC = Cerebral Performance Category Score. The primary outcome of the study is analyzed as the proportion of patients with good neurological outcome in the two groups, (CPC 1-2) at 6 months after CA.

Secondary Outcome Measures

Name	Time	Method
Adverse events	10 days	Adverse events are registered during the treatment and until discharge from primary hospital unit
CPC at discharge	3 month	CPC at discharge from primary hospital unit and after 28 days plus after 3 month
Mortality	6 month	CPC 5 at 6 month
