全身麻醉插管术后院内获得性肺部感染探讨

全身麻醉气管插管术后下呼吸道感染具有较高发生率。分析５２６例手术时间超过４小时普外科病例，经ｕ检验发现全身麻醉气管插管术后患者肺部感染率明显高于持续性硬膜外麻醉术后患者，影响因素主要与全麻插管用具及麻醉机消毒情况有关，也与术前存在慢性阻塞性肺部疾患和术后保留气管插管有关。降低全麻术后肺部感染应重视无菌操作，尽可能对麻醉机管道进行常规消毒。

Analysis of nosocomial pneumonia after general anesthesia

Pneumonia is still a high frequent complication in the postoperative course after intubation in general anesthesia. 526 patients their operative time more than 4 hours were analysed. Univariate analysis demonstrated that the nosocomial pneumonia was significantly higher among patients with general anesthesia than epidural anesthesia, that was related with sterilization of intubator and anesthesia machine, that was also related with chronic obstructive pulmonary disease (COPD) and intubation postoperation. The conclution is to pay attention to aseptic intubation and routine sterilization of anesthesia machine for decreasing nosocomial pneumonia.
