晶体液间断灌注和冷氧合血灌注对心肌保护作用的对比体会

目的：观察冷晶体停搏液（Thomas液）与冷氧合血停搏液对心脏直视手术缺血期间的心肌保护作用。方法：选取98例病人，分为二组，晶体组，冷血组，分别采用含钾冷血停搏液间断灌注与晶体间断灌注保护心肌，从临床效果。心肌酶谱（CK，CK-MB，LDH）等方面评价两组作用。结果：冷血组自动复跳率高于晶体组；低心排率低于晶体组；体外循环后冷血组CK，CK-MB，LDH均低于晶体组，结论：冷氧合血灌注较晶体灌注具有更好的心肌保护作用。

Compare the protection of myocardian between cold crystalloid cardioplegia and thomas solution

Objective: To observe the protection of myocardian of cold crystalloid cardioplegia, and cold blood cardioplegia during ischemia period. Method: 98 patients, who underwent cold crystalloid cardiolegia and cold blood cardioplegia reperfasion, were devided into two groups respectively. Clinical effect and cardiac isoengymes (CK,CK-MB,LDH) etc. are studied to estimare the myocardion protection of each group. Results: Compared with cold crystalloid group, in cold blood group the rate of voluntary heartre-beat is higher, the rate of (LOC) lovo. Cardiac output is lower ,and CK,CK-MB,LDH after CPB(cardio pulmonary bypass) is less. Conclusion: Cold blood cardioplegia perfasion offers a better protection of myocardion than crystalloid cardio plegia.
