Extracorporeal membrane oxygenation (ECMO) is a supportive therapy for patients with severe cardiovascular or respiratory failure refractory to conventional medical therapy. Improvements in ECMO technology, easy access to ECMO devices, and a greater understanding of care of ECMO patients have led to increased utilization of ECMO. The Extracorporeal Life Support Organization (ELSO) registry was established in 1984, to collect data on patients receiving ECMO support to help improve outcomes of these patients. The registry has grown to include over 400 contributing centers from 60 countries with data for more than 90,000 patients. Many investigators have used the ELSO registry to answer clinical questions on outcomes and care of this vulnerable patient population. This report provides a brief summary of 16 peer-reviewed articles that have advanced the knowledge and treatment of neonates, children, and adults supported with ECMO using data from the ELSO registry.
