摘要
本文观察１３０例心内直视手术机械通气期间呼气末二氧化碳分压（ＰｅｔＣＯ２）与ＰａＣＯ２的变化，计算气管插管后１０ｍｉｎ、转流前及体外循环停机后１ｈＰｅｔＣＯ２与ＰａＣＯ２的相关性。结果：转流前法乐氏四联症病人ＰｅｔＣＯ２与ＰａＣＯ２不相关，停机后１ｈ两者之间相关性良好，存在回归关系。提示心内直视手术病人，ＰｅｔＣＯ２与ＰａＣＯ２的相关性放心肺功能正常的病人差，心内直视手术期间应根据病情分别监测ＰｅｔＣＯ２与ＰａＣＯ２，以便维持良好的通气效果。
Abstract According to the types of cardiac abnomality 130patients underwent open heart operations were divided intofour groups, and PetCO2 and PaCO2 were examined.Results show that PetCO2 and PaCO2 were correlated well be-fore bypass in groups,1,3 and 4 while group 2 not.After bypass,PetCO2 and PaCO2 were correlated in groups 1,2,and 3.In group 2(cyanotic anomalies a-ETCO2 was significantly decreased(P<0.05),but increased in the oth-er three noncyanotic groups.It is suggested that relationship of PetCO2 and PaCO2 is not similar in different cardiac disease entities before and after bypass.PetCO2 Open heart operation
