心脏停搏液灌注冠状动脉促使心脏停搏是心脏直视手术中心肌保护的主要方法。心脏停搏技术中应用最广泛的是高钾去极化停搏,目前临床上使用最多的St.Thomas液及其改良液、含血停搏液均为高钾停搏液。但大量研究证明,高钾停搏液仍有不足之处。所以,人们对心脏停搏液的研究始终没 Cardiac cardioplegia infusion of coronary artery to promote cardiac arrest is the main method of myocardial protection during open heart surgery. Cardiac arrest technology is the most widely used is the high-potassium depolarization arrest, the most currently used St.Thomas liquid and its improvement, blood cardioplegia are high-potassium cardioplegia. However, a large number of studies have shown that there are still inadequate high-potassium cardioplegia. Therefore, people’s research on cardioplegia has never been done
