摘要
目的调查分析本院老年手术患者全身麻醉气管插管后院内感染部位及病原体分布特点及其影响因素。方法选择2017年6月-2018年6月在本院行全身麻醉气管插管720例作为研究对象,根据患者术后是否发生院内感染分为发生院内感染120例(观察组),以及未发生院内感染600例(对照组),分析2组患者临床特点,调查记录观察组感染源、病原体分布特点,采用Logistic回归分析探讨患者院内感染的影响因素。结果观察组患者深静脉或动脉穿刺发生率为29.2%,合并有插管困难的患者占75.0%,均明显高于对照组患者,差异有统计学意义(P<0.05)。观察组患者呼吸道感染占50.0%、泌尿道感染占35.0%、切口感染占15.0%,均以革兰阴性菌为主。深静脉或动脉穿刺、插管困难是院内感染的独立危险因素。结论老年全身麻醉术后院内感染以呼吸道感染最为常见,以革兰阴性菌为主,深静脉或动脉穿刺、插管困难增加感染风险。
Objective To investigate the distribution characteristics and influencing factors of nosocomial infections in elderly patients after tracheal intubation under general anesthesia.Methods A total of 720 cases of tracheal intubation under general anesthesia in our hospital from June 2017 to June 2018 were selected by random number table method.120 cases of nosocomial infection occurred in the localized infection group,600 cases of non-infectious patients were assigned to the non-infectious group.The clinical characteristics of the patients were analyzed and the infection sources and diseases of 120 cases of nosocomial infection were recorded.Logistic regression analysis was used to explore the risk factors of nosocomial infection in patients.Results The incidence of deep vein or arterial puncture in the observation group was 29.2%,and 75.0%of patients had difficulty in intubation,which were significantly higher than those in the control group,with the differences statistically signifi-cant(P<0.05).Respiratory tract infection,urinary tract infection and incision infection were 50.0%,35.0%and 15.0%respectively.Gram-negative bacteria were predominant in the infectious group.Deep venous or arterial puncture(P=0.03).Intubation difficulty(P=0.02)is an independent risk factor for nosocomial infection.Conclusion The risk of nosocomial infection in elderly patients after systemic surgery is high.Patients with deep vein or arterial puncture or difficult intubation should be alert to nosocomial infection.
