目的对胸外科手术后患者下呼吸道感染进行监测,分析发生下呼吸道医院感染的危险因素,为下呼吸道医院感染的预防与控制提供依据。方法选取2011年1月至2012年12月840例胸外科手术后患者为监测对象,监测其下呼吸道医院感染的发生情况,对其发生医院感染的危险因素进行分析。结果840例胸外科手术后患者中共发生下呼吸道医院感染101例,感染率12.02%。非条件logistic回归分析结果,住院天数、年龄、手术方式、是否输血、糖尿病史、吸烟史、气管插管/气管切开等因素为胸外科患者术后并发下呼吸道医院感染的危险因素(P<0.05,P<0.01)。结论针对性加强胸外科手术后患者下呼吸道感染危险因素的预防与管理,可降低下呼吸道感染的发生率。
Objective To monitor lower respiratory tract infection in patients after thoracic surgery and analyze the risk factors of nosocomial infection of lower respiratory tract in order to provide basis for the prevention and control of nosocomial infection of lower respiratory tract. Methods From January 2011 to December 2012, 840 patients undergoing thoracic surgery were selected as the monitoring objects to monitor the occurrence of nosocomial infections in their lower respiratory tract and the risk factors of nosocomial infection were analyzed. Results A total of 840 cases of lower respiratory tract nosocomial infection occurred in 840 patients after thoracic surgery, the infection rate was 12.02%. Non-conditional logistic regression analysis, hospital days, age, surgical methods, blood transfusion, history of diabetes, smoking history, endotracheal intubation / tracheotomy and other factors were risk factors for nosocomial infection of lower respiratory tract after thoracic surgery (P < 0.05, P <0.01). Conclusion The prevention and management of risk factors for lower respiratory tract infection in patients undergoing thoracic surgery may reduce the incidence of lower respiratory tract infection.
