AbstractBetween June 1986 and October 1995, 81 patients were emergently resuscitated with a portable extracorporeal life support (ECLS) system. Venoarterial perfusion was achieved using a centrifugal pump (BioMedicus; Medtronic, Anaheim, CA) and a hollow fiber oxygenator (BARD in 56 patients; Medtronic heparin-bonded MAXIMA, [MAXIMA, Medtronic, Minneapolis, MN] in the last 25 patients. The ECLS system was used at various locations in the hospital with the setup, priming, and initiation of perfusion done by ECLS trained intensive care unit nurses. Clinical data in these patients were reviewed to analyze variables influencing survival and trends that develop as the authors' experience accumulated and the technology evolved. The indication for ECLS was cardiac arrest in 68 patients and refractory cardiogenic shock in 13 patients. Thirty-five patients (43.2%) survived > 24 hrs after termination of ECLS, whereas 20 patients (24.7%) are long-term survivors (> 30 days). The ECLS system permitted an additional therapeutic surgical intervention in 45 cases. Patients who had a surgically remediable problem were more likely to survive. Prolongation of cardiopulmonary resuscitation beyond 30 mins before initiation of ECLS correlated with a decreased likelihood of survival.
