Crystalloid and blood cardioplegia in myo-cardial protection

Thirty patients scheduled for elective coronary aı-tery hypass grafting (CABG) were randoınly al-located tü two groups foı- myocaı-dial preservation: crystalloid cardioplegia (group 1), blood car-dioplegia (group 2). In group 1 ,2.4±0.6 distal anas-tomoses for each patient were performed. In the next group (group 2), the numher of distal anastomoses was 2.4±0.7. The demographic pı-ofiles were iden-tical. Crystalloid and hlood cardioplegia were de-livered thı-ought the aortic root intermittently. The patient temperature was kept at 30°C. The study pto-tocol compı-ised recording of the following pa-rameteı-s: 1. Postoperatively positive inotropic and IABP suppoı-t 2. Postoperatively CK-MB, LDH, SGOT and CK enzyme studies 3. ECG changes (rhythm disturbances) 4. Spontaneous sinus rhythm (after removing cross-clamp). The low enzyme values in concerning injury was taken in the blood cardioplegia gı-oub. The results in this study suggest that betteı- myo-cardial pr-otection may be thought to occur hy hlood cardiopegia. We can say that blood cardiopegia is a safi. alternative way of myocaı-dial protection 1,vith good clinical r-esults and lower enzyme levels.
