停搏液是体外循环手术不可缺少药物之一。体外循环中对心肌保护虽然方法很多,如冠状血管动脉氧合血灌注法,心肌局部低温法等,但目前应用较多的是采用心肌降温停跳法,就是采用在4℃左右的冷停搏液快速地灌注到阻断循环的冠状血管内,借助药液内的钾、镁离子,可使心肌很快停止收缩,心肌停跳,使心肌温度大大下降,减少心肌耗氧。根据国内外许多单位报告,停搏液降温停跳效果确切,可靠。其处方组成如下:氯化钾2.0g、氯化钙
Cardioplegia is one of the indispensable drugs for cardiopulmonary bypass. Cardiopulmonary bypass cardioprotection Although there are many ways, such as coronary arterial oxygenation and blood perfusion method, such as myocardial hypothermia, but the current application of more is the use of myocardial cooling and stopping method, is the use of cold at about 4 ℃ Rapid infusion of fluid to the coronary circulation blocking the blood vessels, with the solution of potassium and magnesium ions, can quickly stop the contraction of the heart muscle, myocardial arrest, greatly reduced myocardial temperature, reduce myocardial oxygen consumption. According to many units at home and abroad report, cardioplegia cooling effect is accurate and reliable. The prescription consists of the following: potassium chloride 2.0g, calcium chloride
