心肌再灌注损害是近年术中心肌保护研究中受到重视的课题,本文就其发生机理、表现特点以及预防方法作一综述.心肌再灌注损害在心脏直视手术中,为了获得安静无血的手术野,需要暂时阻断冠状循环血流.近年来,很多观察表明,心肌经过一定时间的缺血,其生化和超微结构的改变较不明显,而在解除主动脉阻断、重新恢复冠状动脉灌注后的早期,出现严重的细胞损害和顽固性 Myocardial reperfusion injury in recent years, the study of myocardial protection in the subject of attention, this article on its mechanism of occurrence, characteristics and prevention methods are reviewed. Myocardial reperfusion injury in open heart surgery, in order to obtain quiet and bloodless surgery In recent years, many observations show that after a certain period of ischemia in the myocardium, the biochemical and ultrastructural changes are less obvious, but in the lifting of the aorta block and restore the coronary artery Early after perfusion, severe cellular damage and intractable
