Could putting a Heart-Lung machine at the scene save more cardiac arrest victims?
NCT ID NCT02527031
First seen Jun 24, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study tested whether starting ECMO (a heart-lung bypass machine) right at the location of a cardiac arrest, rather than waiting until the patient reaches the hospital, could improve survival with good brain function. Researchers enrolled 65 adults with refractory cardiac arrest. The goal was to see if early ECMO could raise survival from around 5% to 20%.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ECMO (extracorporeal membrane oxygenation)
- What this could lead to
- If pre-hospital ECMO works better, it could significantly increase survival rates for people who suffer a cardiac arrest outside the hospital.
- What could go wrong
- This is a small, completed study with only 65 participants, so results may not apply broadly. ECMO carries risks like bleeding and infection, and the benefit over standard care is not yet proven.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Eligible patients have the following combination of criteria: * Adults over 18 years of age and under 65 years of age * And Refractory cardiac arrest (defined by the failure of professionals to resuscitate at the 20th minute of cardiac arrest with a minimum of 3 Automatic External Defibrillator (AED) or equivalent analyze * And Beginning of external cardiac massage within the first 5 minutes after cardiac arrest (no flow \< 5 min.) with shockable rhythm or the presence of signs of life during resuscitation (any rhythm): spontaneous movement, absence of mydriasis and/or pupillary response, spontaneous breathing movements * And Medical cause of the cardiac arrest * And End-Tidal CO2 (ETCO2) above 10 mm Hg at the time of inclusion * And Absence of major co-morbidity. And Extra-corporeal Membrane Oxygenation (ECMO) team available and on-site before the 40th minute Exclusion Criteria: * Children under 18 years of age * Adults over 65 years of age * Period of more than 5 minutes without cardiac massage after collapsing * Known co-morbidity that compromises the prognosis for short or medium-term survival * Cardiac arrest during transportation times
