Brief Summary
The OSIRIS trial is an investigator-initiated, multicenter, multinational, open-label, randomized controlled trial with a 2:1 concealed allocation of refractory out-of-hospital cardiac arrest (OHCA) patients to the extracorporeal cardiopulmonary resuscitation (ECPR) based approach versus the conventional cardiopulmonary resuscitation (CCPR) approach.

Study Arms (2)
ECPR-based
EXPERIMENTALECPR-based approach is defined as advanced cardiac life support (ACLS) per current guidelines with aim to proceed to in-hospital or out-of-hospital veno-arterial extracorporeal membrane oxygenation (V-A ECMO) if return of spontaneous circulation (ROSC) is not achieved before the cannulation.
CCPR
ACTIVE COMPARATORCCPR is defined as conventional advanced cardiac life support (ACLS) per current guidelines without mechanical circulatory support (MCS) use until sustained return of spontaneous circulation (ROSC) is achieved or the patient pronounced dead.
Interventions
ECPR-based approach is defined as ACLS per current guidelines with aim to proceed to in-hospital or out-of-hospital V-A ECMO if ROSC is not achieved before the cannulation.
CCPR is defined as conventional ACLS per current guidelines without MCS use until sustained ROSC is achieved or the patient pronounced dead.
Eligibility Criteria
You may qualify if:
- Age ≥18 and ≤ 70 years presumed or known
- Witnessed OHCA
- Bystander CPR provided
- Presumed cardiac or unknown cause
- An initial documented shockable rhythm of VF (ventricular fibrillation) or pulseless VT (ventricular tachycardia)
- Minimum of ≥ 10 min of ACLS without ROSC or at least ≥ 3 defibrillations in ongoing VF/pulseless VT
- Body morphology able to accommodate a mechanical chest compression device
- ECPR team and intensive care unit (ICU) capacity in the receiving center available
- Estimated transfer time from the scene to the hospital ≤ 30 minutes or to the scene ≤ 30 minutes
- Eligible for intensive care without restrictions or limitations
You may not qualify if:
- ACLS ≥ 30 minutes before randomization
- Known limitations in care or a Do Not Attempt to Resuscitate (DNAR) order
- Known severe disease making 90-day survival unlikely
- Known bleeding diathesis or acute or recent intracranial bleeding
- Known, obvious or suspected pregnancy
- Known pre-arrest severe cognitive dysfunction (mRS ≥ 4)
- Known hypothermia as a cause of cardiac arrest
