全麻气管插管术后患者肺部感染的调查分析

目的 了解全麻气管插管手术后,肺部感染情况,采取控制措施.方法 对2007年1-12月全麻气管插管患者,按设计的调查表格进行登记.结果 调查手术患者2914例,全麻气管插管患者471例,肺部感染95例感染率20.17%;插管时间<24 h感染率5.38%,>24 h感染率41.67%;痰培养革兰阴件菌64株,占5.65%,革兰阳性菌32株,占28.83%,真菌15株,占13.52%.结论 插管时间越长,感染率越高,机械通气是造成感染的重要危险因素;缩短插管时间,减少机械通气,严格消毒火菌隔离管理,是控制感染的重要措施.

Investigation and Analysis of Patients with Lung Infection After Tracheal Intubation General Anesthesia

OBJECTIVE To know the risk factors about lung infection in patients after tracheal intubation general anesthesia and take control measures. METHODS All the patients with tracheal intubation general anesthesia from Jan to Dec in 2007 were investigated retrospectively. RESULTS Among 2914 operation cases, 471 cases were of tracheal intubation general anesthesia and 95 cases were infected (20.17%). The infection rate was 5.38%(<24 hours) and 41.67% (>24 hours). Sputum culture: G~- bacteria accounted for 57.65%, G~+ bacteria 28.83%,fungi (13.52%). CONCLUSIONS The infection rate increase with longer intubation time. Mechanical ventilation is a risk factor of lung infection. The measures to control infection include shortening intubation hours, reducing mechanical ventilation and strictly sterilization and isolation.
