本文将携氧氟碳(全氟正三丙基胺,简称FTPA)冷心停波液(A组)与St Thomas冷心停液(B组)的心肌保护效果,作了兔离体心脏灌注的实验比较研究。结果证明,用FTPA配制的冷心停搏液(4℃),在主动脉根部持续灌注60分钟,心肌组织中未见有蓄积现象。作者认为,氟碳心停搏液对体外循环心肌保护属局部通过作用,并不进入全身循环,故更为安全。本实验A、B两组在心停搏期间,LDH释放活力单 In this paper, the myocardial protection effect of Oxyfluorocarbon (Perfluorotripropine) (FTPA) cold stop wave solution (Group A) and St Thomas cold stop solution (Group B) Experimental comparison study. The results show that, with the preparation of the FTPA cold cardioplegia (4 ℃), continuous aortic root perfusion 60 minutes, no accumulation of myocardial tissue. The author believes that fluorocarbon cardioplegia on cardioprotection of cardiopulmonary bypass through the role of local and does not enter the systemic circulation, it is more secure. This experiment A, B two groups during cardiac arrest, LDH release vitality alone
