摘要

摘要: 目的:评价压力控制机械通气在小儿气道异物取出术中的通气效果。方法:拟行气道异物取出术的患儿90例,年龄10个月~3岁,体重8~16 kg,ASAⅡ~Ⅲ级。随机分为H组(30例)、P组(30例)和S组(30例):H组高频喷射通气,P组通过硬支气管镜侧孔行压力控制机械通气,S组保留自主呼吸。记录患儿术前、术毕即刻血气分析,记录术者置镜满意情况、术中缺氧发生率、异物取出情况、手术时间、麻醉苏醒时间和不良事件(屏气、呛咳、支气管或喉痉挛、躁动)的发生情况。结果:术前3组血气结果差异无统计学意义;S组术毕的动脉氧分压明显低于H组和P组(P<0.05),CO₂分压则高于H组和P组(P<0.05);与S组比较,H组与P组术者置镜满意情况、术中缺氧发生率、异物移除情况、手术时间及麻醉苏醒时间等差异有统计学意义(P<0.05),与H组比较,P组手术时间及麻醉苏醒时间、术中缺氧发生率、术毕血气结果差异无统计学意义(P>0.05)。结论:压力控制机械通气用于小儿异物取出术,与高频喷射通气效果相当,且安全可靠,操作简便。

Abstract: Objective:To evaluate the effects of pressure controlled ventilation for tracheobronchial foreign body removal in children.Method:Ninety ASA Ⅱ or Ⅲ children,aged 10 months to 3 yr,weighing 8-16 kg undergoing removal of airway foreign body were randomly divided into 3 groups(n=30 each):group Ⅰ pressure controlled ventilation(P),group Ⅱ high-frequency jet ventilation(H),and group Ⅲ, reserve spontaneously breathings.Arterial blood gas analysis of Pre-operation and the end of operation, the occurrence of hypoxia during operation, the duration of operation,anesthesia emergence time and perioperative side effects were recorded.Result:The arterial blood gas analysis (PaO₂,PaCO₂,SaO₂)and SPO₂ of Pre-operation in group P and H had no significant difference. The PaO₂ of the end of operations was significantly higher,and PaCO₂ was lower in group H.The occurrence of hypoxia during operation, the duration of operation,anesthesia emergence time and perioperative side effects in two group had no significant difference.Conclusion:The effects of pressure controlled ventilation and high-frequency jet ventilation for tracheobronchial foreign body removal in children were nearly the same,and pressure controlled ventilation can be commonly used in clinic.
