气管插管和气管切开术后并发肺部感染的相关因素分析

目的 了解气管插管和气管切开术后并发肺部感染的相关因素，探讨预防的方法。方法 对近3年我院收治的经气管插管和气管切开运用呼吸机治疗的69例病人进行回顾性调查。结果 69例病人中48例术后出现肺部感染占69．57％。致病菌主要为革兰氏阴性(G^-)菌，占79．05％，其中首位是铜绿假单胞菌，占36．59％；第二位是肺炎克雷伯氏菌和真菌，占14．63％。结论 气管插管和气管切开术后易并发肺部感染，致病菌以G^-菌为主。

A study on the correlative factors that cause complicated pneumonia after tracheal intubation and tracheotomy

Objective To understand the correlative factors that cause complicated pneumonia after tracheal intubation and tracheotomy, and explore the ways of prevention.Methods A retrospective survey had been done on 69 patients who were treated by artificial respiratory machine after tracheal intubaton and tracheotomy in our hospital in recent 3 years.Results 48 of the 69 patients complicated pneumonia, the rate was 69.57%; The major pathogens were G - bacterium, the rate was 79.05%; And the fist place was Pseudomonas aeruginasa, the rate was 36.59%; The second place was Klebsiella pneumoniae and fungi, the rate was 14.63%.Conclusions It is very easy to complicate pneumonia after tracheal intubation and tracheotomy, and the major pathogens were G - bacterium.
