What this Trial Is About
This research evaluates temperature control methods after extracorporeal cardiopulmonary resuscitation (ECPR) in adults who suffered out-of-hospital cardiac arrest (OHCA). The trial compares hypothermia and normothermia approaches to understand their effects on survival, neurological outcomes, and adverse events. While cooling is believed to protect the brain after cardiac arrest, recent studies question its benefits, especially in patients treated with ECPR using extracorporeal membrane oxygenation (ECMO).

Who Can Participate
Eligibility Criteria
You may qualify if you...

You will not qualify if you...
- ECMO started after sustained return of spontaneous circulation (ROSC) or sustained ROSC before ECMO
- OHCA caused by non-cardiac reasons
- Time from emergency call or witnessed arrest to hospital arrival over 60 minutes
- Time from hospital arrival to ECMO initiation over 60 minutes
- Pre-hospital ECPR
- ECMO heat exchanger not available for temperature control
- Glasgow Coma Scale score above 8 before temperature control
- Core body temperature 32°C or lower upon hospital arrival
- Surgical intervention before temperature control
- Do Not Attempt Resuscitation order before temperature control
- Limitations in intensive care before temperature control
- Known cerebral performance category of 3-4 before cardiac arrest
- Chronic obstructive pulmonary disease requiring home oxygen
- Known or suspected pregnancy
- Serious illness like cancer likely to shorten life expectancy
- Consent not obtained or withdrawn
- Other physician-decided reasons not to enroll

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 screening and enrollment visit
Duration - Approximately 3 days
Participants receive temperature control after extracorporeal cardiopulmonary resuscitation (ECPR) where they are cooled to either 33-34°C (hypothermia group) or maintained at 36°C (normothermia group) using ECMO with a heat exchanger. The target temperature is maintained for 24 hours, followed by rewarming over 24 hours, then temperature is kept between 36°C and 37.5°C for 24 hours or until the end of ECMO support.
Continuous monitoring during intensive care unit stay (average 2 weeks)
Duration - Up to 1 year after admission
Participants are monitored for survival and neurological function at discharge and at 30 days, 90 days, and 1 year after admission.
1 visit at discharge and follow-up assessments at 30 days, 90 days, and 1 year
