摘　　要：目的探讨气管插管全麻手术后发生下呼吸道感染的麻醉相关因素,为临床提供理论依据。方法选取2012年12月-2014年1月实施全麻气管插管手术患者630例,分析发生感染的相关因素,采用SPSS 16.0软件进行统计分析。结果 340例患者发生感染,感染率53.97%;插管过深、插管不熟练、拔管指征不完全、拔管延迟且>3h为发生感染的危险因素(P<0.05);共分离出790株病原菌,以革兰阴性菌为主,共463株占58.61%。结论引发气管插管全麻手术后患者下呼吸道发生感染的相关危险因素较多,需要引起注意,针对性预防,降低感染率。OBJECTIVE To investigate the anesthesia-related factors for lower respiratory tract infection after tracheal intubation under general anesthesia,so as to provide a theoretical basis for clinical treatment.METHODS Totally 630 cases undergoing tracheal intubation during Dec.2012-Jan.2014 were selected to analyze the relevant factors.The software SPSS 16.0was used for statistical analysis.RESULTS Totally 340 patients had infections with the infection rate of 53.97%.The risk factors for infections were excessively deep intubation,unskilled intubation,incomplete indicators for intubation and intubation delay 3h（P〈0.05）.A total of 790 bacteria were isolated,mainly including gram-negative bacteria（463strains,58.61%）.CONCLUSION Various risk factors can lead to lower respiratory tract infections after tracheal intubation under general anesthesia which requires attention and targeted prevention to reduce infection rates.
