本文应用体外循环心脏手术动物模型，实验犬随机分为对照组、温血组和C93加温血组。评估主动脉阻断前、阻断60＇末和再灌注60＇期间的心肌水肿、线粒体的形态和立体定量分析，以反映心肌保护的效果。结果表明：温血灌注对心肌的保护作用优于低温灌注，而C93可以增强温血灌注的心肌保护作用。
In this paper, cardiopulmonary bypass cardiac surgery animal model, experimental dogs were randomly divided into control group, warm blood group and warm C93 group. To assess myocardial edema at the end of 60 ’and reperfusion 60’ before mitral aortic blockage, morphological and quantitative analysis of mitochondria to reflect the effect of myocardial protection. The results showed that the protective effect of warm blood perfusion on myocardium is better than that of hypothermic perfusion, while C93 can enhance the myocardial protective effect of warm perfusion.
