摘要 目的观察同期双侧开胸手术中单肺两种通气模式应用时,病人的氧合、血流动力学变化,探讨其效果和肺保护作用。方法 96例病人分为两类,第一类53例单肺通气后采用VCV模式通气,第二类43例单肺先采用VCV模式通气,在出现气道峰压持续升高(PPEAK>40 cm H2O),改用PCV模式通气,观察病人的氧合及血流动力学变化。结果第一类病人VCV模式通气时能保证基本组织氧合;第二类病人PCV模式与VCV模式通气时相比较,气道压明显降低,PH值增大(P<0.01),PaO2增高(P<0.01),PaCO2降低(P<0.05),SpO2升高,PETCO2降低,差异有统计学意义;HR、CVP、MAP略降低(P>0.05),差异无统计学意义。未发生气压伤等机械通气并发症。结论同期双侧开胸微创手术中,灵活运用两种机械通气模式可较好的维持麻醉病人单肺通气时的呼吸循环管理,有效的避免机械通气并发症的发生,实施肺保护。
