Extracorporeal cardiopulmonary resuscitation for out-of-hospital cardiac arrest: A meta-analysis of randomized controlled trials.

ECPR in OHCA patients was not associated with improved survival or long-term favorable neurological outcome but did improve favorable neurological outcome in the mid-term. However, these results are likely underpowered due to the small number of available RCTs. Large-scale confirmatory RCTs are needed to provide definitive conclusions.
