目的了解肺癌患者手术后感染的危险因素,为有效防控提供依据。方法采用回顾性研究方法 ,对2011年1月-2013年12月某三级医院胸外科收治的232例确诊为肺癌并进行手术的患者术后感染情况进行分析。结果肺癌患者手术后发生医院感染共计105例、107例次,医院感染发生率为45.26%、例次感染率为46.12%。2011-2013年间医院感染发生率分别为36.21%、52.78%和45.10%。医院感染的发生与患者年龄、住院天数、使用呼吸机以及术后转过重症监护病房(ICU)等因素有关。病原菌构成肺炎克雷伯菌17株,鲍曼不动杆菌9株,白色念珠菌8株,阴沟肠杆菌7株。结论该院肺癌患者手术后医院感染发生率较高,感染的病原菌以革兰阴性菌为主,真菌也占有相当的比例,应引起重视。
Objective To understand the risk factors of postoperative infection in patients with lung cancer and provide the basis for effective prevention and control. Methods A retrospective study was conducted to analyze the postoperative infection of 232 patients diagnosed as lung cancer who underwent surgery in the thoracic surgery department of a tertiary hospital from January 2011 to December 2013. Results A total of 105 cases of nosocomial infections occurred in patients with lung cancer after operation, 107 cases were hospitalized, the incidence of nosocomial infection was 45.26%, and the infection rate was 46.12%. The prevalence rates of nosocomial infections in 2011-2013 were 36.21%, 52.78% and 45.10% respectively. The incidence of nosocomial infections is related to the patient’s age, number of days of hospitalization, the use of a ventilator, and the conversion to an intensive care unit (ICU) after surgery. Pathogenic bacteria constitute Klebsiella pneumoniae 17, Acinetobacter baumannii 9, Candida albicans 8, Enterobacter cloacae 7. Conclusion The incidence of nosocomial infections in patients with lung cancer after operation in this hospital is high. Gram-negative bacteria are the main pathogens in the hospital, and fungi also occupy a considerable proportion, which should be paid more attention.
