[目的]探讨恶性肿瘤患者发生院内感染的相关因素,以期为预防院内感染提供参考。[方法]对2007年1月～2010年1月收治的123例恶性肿瘤患者的临床资料进行回顾性分析,分析内容包括患者的年龄、住院时间、发生院内感染的病原菌、感染部位及发生院内感染的肿瘤类型。[结果]①革兰阴性杆菌所占百分比为63.41%,革兰阳性球菌所占百分比为36.95%;②患者年龄越大,发生院内感染的机率越高;③患者住院期间以住院﹥30d发生院内感染率最高;④下呼吸道发生院内感染最多,所占百分比为60.97%;⑤呼吸道系统肿瘤发生院内感染率最高,所占百分比为49.59%。[结论]患者的年龄、住院时间等为恶性肿瘤患者发生院内感染的危险因素,临床在治疗恶性肿瘤过程中应避免院内感染的发生。
[Objective] To explore the related factors of nosocomial infection in patients with malignant tumors, in order to provide reference for the prevention of nosocomial infections. [Methods] The clinical data of 123 patients with malignant tumors admitted to our hospital from January 2007 to January 2010 were analyzed retrospectively. The analysis included the age of patients, length of hospital stay, pathogens causing nosocomial infections, sites of infection and nosocomial infections Of the tumor type. [Results] ①The percentage of Gram-negative bacilli was 63.41% and the percentage of Gram-positive cocci was 36.95%. ② The older the patients were, the higher the incidence of nosocomial infection was. ③The patients were hospitalized within 30 days The highest infection rate; ④ the most common nosocomial infection in the lower respiratory tract, the percentage of 60.97%; ⑤ the highest incidence of nosocomial infection in the respiratory system, the percentage was 49.59%. [Conclusion] The patients’ age and length of hospital stay are the risk factors of nosocomial infection in patients with malignant tumors. The incidence of nosocomial infections should be avoided in clinical treatment of malignant tumors.
