自从体外循环于1951年开始应用于临床以来,许多心脏病能在心内直视手术下得到矫治,但是由于心脏较长时间的缺血,缺氧引起了一系列不良后果,如心脏复苏困难,低排综合症,“石样心”等严重并发症,甚至导致病人死亡。因此近20多年来,对此进行了广泛的研究,使心肌保护技术一再得到改讲。 Since cardiopulmonary bypass was introduced into the clinic in 1951, many heart diseases have been corrected under open heart surgery. However, due to prolonged ischemia of the heart, hypoxia causes a series of adverse consequences such as difficulty in cardiac recovery and low Row syndrome, “stone heart” and other serious complications, and even lead to the death of patients. Therefore, over the past 20 years, extensive research has been carried out to make myocardial protection technology repeatedly changed.
