摘要 目的:观察采用不同潮气量机械通气对神经外科手术患者呼吸力学的影响。方法:神经外科全麻手术的患者60例,年龄30~50岁,体重40~75 kg,均选择平卧位手术者,随机分为3组,潮气量(TV)为6 ml/kg(Ⅰ组)、潮气量(VT)为8 m L/kg(Ⅱ组)、潮气量为12 m L/kg(Ⅲ组),每组20例。分别于机械通气后1 h(T1)、3 h(T2)、5 h(T3)记录患者气道峰压、气道平台压、呼气末二氧化碳分压、动态肺顺应性。结果:在T1、T2、T3时点,Ⅰ组、Ⅱ组比Ⅲ组的气道峰压、气道平台压明显降低而呼气末二氧化碳分压升高,差异有统计学意义(P〈0.05),3组肺动态顺应性差异无统计学意义。结论:术中使用6~8 m L/kg潮气量机械通气不改变肺顺应性同时可以维持较低的气道压,是较为合理的潮气量选择。
