Extra-corporeal membrane oxygenation during the beating heart coronary artery bypass grafting for ;high risk patients-a single center experience / 中国介入心脏病学杂志

ABSTRACT

Objective To summarize clinical application, method and result of extra-corporeal membrane oxygenation ( ECMO) used during beating heart coronary artery bypass grafting ( CABG) in high risk patients. Methods Twenty one patients [ mean age ( 75. 7 ± 3. 6 ) years old ] who received beating-heart CABG surgery assisted with ECMO were included in the study. We observed the condition when ECMO weaned off, the duration on mechanical rentilato time of ICU stay and the occurance of related complications. Results Among the 21 patients, ECMO was weaned off uneventfully after surgery in 8 patients. Immediate weaning was failed in another 8 patients and required gradual weaning in 2. 0-4. 5 hrs. Five patients could not wean off the ECMO in operation room needing continuous ECMO support in CCU. ECMO was weaned off in CCU gradually with IABP support [mean IABP support time (115. 0 ± 25. 9) hrs]. Among the 5 patients admitted into CCU, 1 patient had oozing from insertion site at femoral artery/rein region and was stopped with compressive bandage. Lower limb ischemia happened in another 1 patient and was recovered after set up of by-pass circulation. All 21 patients recovered well and smoothly. Mean in-hospital stay was (17. 4 ± 2. 8) d. Conclusions ECMO is a safe and effective circulatory support during beating heart coronary artery bypass surgery for high-risk patients with severe coronary artery disease in reducing the mortality and complications.
