目的探讨分析行消化道内镜下手术治疗患者医院感染特点及危险因素,为医院感染的防治提供参考。方法选取2008年1月-2015年6月医院行消化道内镜手术治疗的424例患者为研究对象,回顾性分析医院感染的特点及引发感染的危险因素;采用SPSS19.0软件进行统计分析。结果 424例患者中发生医院感染118例,感染率为27.83%;其中胃镜手术感染率高于结肠镜下手术感染率(P<0.05);患者医院感染部位以呼吸道、泌尿系感染为主,分别占39.83%和27.97%;共检出病原菌58株,以幽门螺杆菌、肺炎克雷伯菌、金黄色葡萄球菌、表皮葡萄球菌为主,分别占36.21%、24.14%、20.69%、12.07%;患者年龄≥65岁、为恶性疾病、合并有并发症、有其他侵入性操作、使用免疫抑制剂、住院时间≥14d是导致消化道内镜手术患者发生医院感染的危险因素(P<0.05)。结论行消化道内镜手术治疗患者医院感染率较高,发生医院感染的危险因素较多,应针对危险因素,采取相应的预防措施,从而控制和降低医院感染的发生。
Objective To investigate the characteristics and risk factors of nosocomial infections in patients undergoing endoscopic gastrointestinal endoscopy and provide references for the prevention and treatment of nosocomial infections. Methods A total of 424 patients undergoing endoscopic gastrointestinal surgery from January 2008 to June 2015 in our hospital were selected as research objects. The characteristics of nosocomial infection and the risk factors of infection were retrospectively analyzed. The data were analyzed by SPSS19.0 software. Results Among the 424 cases, nosocomial infection occurred in 118 cases, the infection rate was 27.83%. The infection rate of gastroscopy surgery was higher than that of colonoscopy operation (P <0.05). The majority of nosocomial infections were respiratory tract and urinary tract infection, respectively Accounting for 39.83% and 27.97% respectively; 58 strains of pathogens were detected, accounting for 36.21%, 24.14%, 20.69% and 12.07%, respectively, of Helicobacter pylori, Klebsiella pneumoniae, Staphylococcus aureus and Staphylococcus epidermidis. Patients aged ≥ 65 years were malignant diseases with complications. Other invasive procedures and immunosuppressive agents were used. The length of hospital stay ≥14 days was the risk factor for nosocomial infection in patients with gastrointestinal endoscopy (P <0.05). Conclusions The hospital infection rate in patients undergoing endoscopic gastrointestinal surgery is high, and there are many risk factors for nosocomial infection. Corresponding preventive measures should be taken according to risk factors so as to control and reduce the occurrence of nosocomial infections.
