Early Extracorporeal CPR for Refractory Out-of-Hospital Cardiac Arrest
INCEPTION trial design and results
Design
Multicentre randomised controlled trial
Treatment
Extracorporeal cardiopulmonary resuscitation
Control
Conventional cardiopulmonary resuscitation
Population
134 analysed patients with refractory out-of-hospital cardiac arrest, of 160 randomised
Follow-up
30 days
Primary endpoint
Survival with a favourable neurological outcome at 30 days
Result
70 patients were assigned to extracorporeal CPR and 64 to conventional CPR, with 26 excluded for not meeting inclusion criteria at hospital admission. Survival with favourable neurological outcome was similar between strategies.
Secondary endpoints
30-day and 6-month survival, complications
In patients with refractory out-of-hospital cardiac arrest, extracorporeal CPR and conventional CPR had similar effects on survival with a favorable neurologic outcome.

How it has aged
Pragmatic and multicentre, and therefore more representative than the single high-volume-centre series that generated enthusiasm for extracorporeal CPR. Whether the intervention fails or the logistics do — time to cannulation is everything — remains contested.
