【摘要】 目的 观察腹腔镜手术气腹后调整呼吸参数对呼气末二氧化碳分压的影响。方法 妇科腹腔镜手术ASAⅠ～Ⅱ级患者60例，随机分成两组，A组:术中呼吸参数不变;B组:根据呼气末CO 2 分压(P ET CO 2 )随时调整呼吸参数。监测两组P ET CO 2 、气道压(Paw)、肺顺应性(Comp)。结果 两组患者气腹后P ET CO 2 与Paw都较气腹前升高，但A组P ET CO 2 与Paw升高更明显;B组P ET CO 2 基本维持在正常范围内;两组同时点比较差异有非常显著性(P<0.01);Comp两组都较气腹前降低，差异无显著性。结论 调整呼吸参数可降低腹腔镜手术因CO 2 气腹而升高的P ET CO 2 ，减少发生高碳酸血症的危险。

    【Abstract】 Objective To observe the effect of adjusting respiratory parameter on P ET CO 2 of gynecological laˉparoscopic surgical patients after carbon dioxide pneumoperitoneum.Methods 60cases，ASA gradeⅠ～Ⅱ，were randomly divided into two groups.Group A:maintaining a fixed respiratory parameter in the whole operation.Group B:adjusting respiratory parameter according to P ET CO 2 .At the same time，P ET CO 2 ，Paw and Comp of all patients were deˉtected.Resul

    ts In two groups P ET CO 2 after carbon dioxide pneumoperitoneum were significantly higher than P ET CO 2 before pneumoperitoneum.But in group A P ET CO 2 was above the normal range.Furthermore ......
