Keyword:  麻醉全身间歇正压通气压力控制通气;
Abstract: 目的:了解全身麻醉时间歇正压通气(IPPV)和压力控制通气(PCV)的差异.方法:选取12例神经外科手术患者.手术期间应用Dr ger Primus呼吸机行IPPV和PCV.记录呼吸力学指标,呼气末二氧化碳分压,并行动脉血气分析.计算生理无效腔(Vu).组间采用配对t检验,P<0.05为差异有显著性.结果:所有患者均顺利完成各项观察.动脉血氧分压(PaO2)在PCV时显著降低,在IPPV时又升高恢复基础水平,Vu差异无显著性.IPPV与PCV比较,PaO2显著升高.结论:在全身麻醉期间选择IPPV还是PCV,要综合考虑手术因素和患者本身的特点.对于肺换气功能异常的患者可以选用PCV,而对于心肺功能良好的成年患者使用IPPV,能更好地保证患者术中的氧合.
