Objective To summarize the clinical experiences of venoarterial extracorporeal membrane oxygenation (ECMO) which provides temporary cardiopulmonary assist for critical patients, and preliminary analysis of the cause of failure. Methods From February 2005 to October 2008, 58 adult patients (male 42, female 16) undergoing cardiogenic shock required temporary ECMO support. Age was 44.8±17.6 years, and support duration of ECMO was 131.9±104.7 hours. There were 24 patients (41.4%) with coronary heart disease, 11 patients (19.0%) with cardiomyopathy, 10 patients (17.2%) with cardiac valve disease,and 9 patients (15.5%) with congenital heart disease. Results 22 patients died in hospital. 11 patients (50%) died of multisystem organ failure, 5 patients (22.7%) died of refractory heart failure despite the ECMO support. Another patients died of bleeding and severe pulmonary hypertension etc. The percentage for patients need cardiac resuscitation before ECMO support and patients with acute renal failure treated by continuous renal replacement therapy (CRRT) under ECMO support were obviously higher in dead patients than those in survivor patients (45.5% vs.19.4%, 40.9% vs. 5.6%; P=0.043，0.001). All of the discharged patients were reassessed, mean followup time were 15.6 months. Three patients died of refractory heart failure， 1 patient died of neurologic complications. The other 32 survivors were in good condition with cardiac symptom of New York Heart Association class Ⅰ or Ⅱ. Conclusion ECMO offers effective cardiopulmonary support in adults. Early intervention and control of complications could improve our results with increasing experience. Combining using CRRT during the ECMO support is associated with significantly higher mortality rate. Suffered cardiac arrest prior to ECMO also influences the survival.
