Update and outcomes in extracorporeal life support

Abstract

The Extracorporeal Life Support Organization Registry has collected outcome data of almost 56,000 patients receiving extracorporeal life support (ECLS) over the last 24 years. The use of neonatal respiratory ECLS declined from a peak of 1516 cases in 1992 to 750-865 cases from 2008 to 2012. The 26,583 cases of neonatal respiratory ECLS (75% survival) represent the largest patient population in the registry. Indicating the rapid growth in other patient populations, 2013 marks the first year where the number of neonatal respiratory ECLS cases is less than 50% of the registry. Stagnant at ~200 cases/year from 1993 to 2004, growth is occurring in the use of pediatric respiratory ECLS with 331-448 cases/year from 2008 to 2012 (58% survival). Similarly, adult respiratory ECLS use increases have been seen from ~100 cases/year from 1996 to 2007 to 480-846 cases/year from 2009 to 2012 (58% survival). Just over 15,000 cardiac ECLS patients have survival rates of 40%, 49%, and 40% for neonates, pediatric, and adults, respectively.
