Hadaya J, Dobaria V, Aguayo E, et al. - Researchers investigated temporal trends and predictors of extracorporeal life support (ECLS) utilization and survival to discharge among inpatients with cardiac arrest in the United States. From the National Inpatient Sample, they recognized 1,624,827 patients who were admitted after out-of-hospital cardiac arrest or had experienced in-hospital cardiac arrest from 2005 to 2014. During the study period, they observed an increase in the use of ECLS from 77 to 564 per 100,000 arrests for OHCA, and 60–632 per 100,000 arrests for IHCA. The analysis revealed a substantial reduction in mortality after cardiac arrest for those on ECLS. For survival or utilization, younger age, shockable rhythm, and out-of-hospital arrest location were predictive. As ECLS use raises, it is crucial to describe selection criteria that maximize the advantages of ECLS.
