Abstract:
Objective: To observe two methods of cardioplegia under intrograde and retrograde, using mixed hypothemic blood in 59 patients receiving coronary artery bypass graft (CABG). Method:During perioperation and postoperation 24 hours,hemodynamie parameters were recorded. Myocardial enzyme level,the changes of ECG on 12 leads in postoperation,the frequency of using inotrope,time of staying in ICU and automatical reovery heart beat rate after openning aortic clamp were tested. Result: Cardioplegia by mixed hypothemie blood had better protective effects to the heart function, all patients could left the ICU safely,without significant differences between the two methods of cardioplegia,but in the retrograde group,there was obvious reduce in the change of myocardial enzyme level and less change of ECG in postoperation compared with those in the intrograde group. Conclusion:Both methods of mixed hypothemic blood for cardioplegia in CABG can protect effetively myocardium, but retrograde eardiaoplegia has better effect.
