【摘要】：目的探讨气管插管全麻术患者术后发生下呼吸道感染的危险因素及相关预防治疗措施。方法回顾性分析2010年9月-2014年11月在医院行气管插管全麻术的675例患者临床资料,其中50例患者术后发生下呼吸道感染,分析患者发生下呼吸道感染的相关因素;并进一步通过多因素logistic回归分析患者发生下呼吸道感染的危险因素。结果 675例行气管插管全麻术患者,术后发生下呼吸道感染50例,感染率7.4%;下呼吸道感染患者的痰液培养出31株病原菌,其中革兰阴性菌25株占80.6%,革兰阳性菌5株占16.2%,真菌1株占3.2%;单因素分析显示,年龄≥50岁、有吸烟史、麻醉时间3h、合并基础疾病、插管部位、插管途径、拔管时间延迟以及插管深度与下呼吸道感染的发生明显相关,且差异有统计学意义(P0.05);进一步多因素分析显示,年龄≥50岁、麻醉时间3h、插管途径、插管部位、插管深度以及拔管时间延迟是患者发生下呼吸道感染的独立危险因素(P0.05)。结论临床上应该加强对该危险因素的控制,以降低患者发生下呼吸道感染的风险。
[Abstract]:Objective to investigate the risk factors of lower respiratory tract infection in patients undergoing tracheal intubation and general anesthesia.Methods the clinical data of 675 patients undergoing general anesthesia with tracheal intubation in hospital from September 2010 to November 2014 were analyzed retrospectively. Among them, 50 cases developed lower respiratory tract infection after operation, and the related factors of lower respiratory tract infection were analyzed.The risk factors of lower respiratory tract infection were further analyzed by multivariate logistic regression analysis.Results among 675 patients undergoing tracheal intubation and general anesthesia, 50 cases of lower respiratory tract infection occurred after operation, the infection rate was 7.4%, 31 strains of pathogenic bacteria were cultured in sputum of patients with lower respiratory tract infection.Among them, 25 Gram-negative bacteria accounted for 80.6, 5 Gram-positive bacteria accounted for 16.2and 1 fungus accounted for 3.2.The univariate analysis showed that the age 鈮，
