  ABSTRACT: To describe the experience with extracorporeal membrane oxygenation (ECMO) for cardiorespiratory support of 100 patients. Retrospective analysis of the medical files of 100 patients submitted to the implant of extracorporeal membrane oxygenation system for cardiorespiratory assistance of acute and refractory cardiogenic shock from December 2004 to September 2008. There were 67 males and 33 females, age ranged from 5 d to 76 years with a mean of (28+/-26) years, body mass ranged from 3.8 to 100.0 kg with a mean of (42+/-30) kg. The inter-surface of the ECMO equipment system was completely coated by heparin-coating technique. All patients were applied veno-artery ECMO and activated clotting time was maintained between 120 and 180 s and heparin usage dose was 5 to 20 Uxkg(-1)xh(-1). Mean blood flow was 40 to 220 mlxkg(-1)min(-1) during ECMO assistant period. The shortest ECMO time was 12 to 504 h with a mean of (119+/-80) h. Sixty-one patients (61.0%) weaned off successfully from ECMO, 55 of them (90.2%) were discharged and 6 died of post-operative complications. Thirty-nine patients could not weaned off from ECMO. Total survival discharge rate was 55.0%. Mean aortic pressure before ECMO in survived patients was significantly higher than that of dead patients (P=0.038). Lactic acid concentration of artery blood before ECMO in survived patients was significantly lower than that of dead patients (P=0.005). ECMO is an effective mechanical assistant therapy method for cardiac and pulmonary failure after cardiac surgery. Earlier usage of ECMO for heart lung failure patient and avoiding the main organs from un-recovery trauma are key success.

  ABSTRACT: The purpose of this study was to retrospectively summarize and analyze the data of 99 cases with the application of consecutive extracorporeal membrane oxygenation (ECMO) from December 2004 to August 2008 in Fuwai Hospital. The intersurface of the ECMO equipment system was completely heparin coated. All patients received venoarterial ECMO, and the activated clotting time was maintained between 120 and 180 seconds. The heparin dose was 5-20 U * kg(-1) * h(-1). Mean blood flow was 40-220 ml * kg(-1) * min(-1) during ECMO assisted period. The shortest ECMO time was 12 hours, and the longest was 504 hours (mean time, 119.45 +/- 80.20 hours). Sixty patients (60.6%) weaned from ECMO successfully; 54 of them (84%) were discharged, and six died of postoperative complications. Thirty-nine patients could not wean from ECMO. Total discharge rate was 54.5%. ECMO is an effective mechanical assistant therapy for cardiac and pulmonary failure after cardiac surgery. Earlier use of ECMO for heart lung failure patients and avoidance of irreversible damage to the main organs are still the key points in the success of ECMO.
