Emergency total ECLS vs standard ACLS with bailout ECMO for OHCA survival

Official title: Emergency Total Extracorporeal Life Support Versus Standard Advanced Cardiac Life Support With ECMO Bailout for Survival With Favorable Neurological Outcome in Refractory Out-of-Hospital Cardiac Arrest

Run by Taipei Medical University Shuang Ho Hospital · NCT06692075 · Data updated 2026-11-12

This trial tests whether starting total extracorporeal life support early helps adults with witnessed OHCA survive with good brain function better than starting standard ACLS and adding ECMO only if needed.

Is this trial a fit for you?

Likely a good fit

Adults 18-75 with witnessed OHCA, bystander CPR, initial shockable rhythm, multiple shocks, and transportation time under 30 minutes.

Probably not a fit

Patients outside age range, non-shockable rhythm, or with contraindicating conditions may not benefit and could face procedure-related risks.

What this trial studies

This is a randomized interventional study enrolling adults 18-75 with witnessed OHCA, bystander CPR, shockable rhythm, multiple defibrillations, and transport time under 30 minutes. Participants are randomized 1:1 to receive emergency total ECLS or standard ACLS with bailout ECMO, with stratification by site. All patients receive emergency coronary revascularization, intensive care, and up to 180 days of follow-up. The trial aims to determine if earlier, full ECLS improves survival with favorable neurological outcome compared with the staged approach. Informed consent is waived due to emergency research conditions in the ED setting.

Why it matters

Potential benefit: If successful, the approach could increase survival with good neurological function after OHCA by enabling earlier circulatory support.

How similar studies have gone: Previous evidence suggests potential benefit of ECLS in refractory OHCA, but the optimal timing and strategy remain unproved, making this approach exploratory.
