摘　　要：目的探讨消化道内镜检查患者发生感染的情况,以了解其感染的主要危险因素,为临床治疗提供参考依据。方法选取2000年3月-2011年12月697例行消化道内镜检查住院患者,对行消化内镜发生感染患者进行病原菌培养,数据采用SPSS 16.0软件进行统计分析。结果共有55例发生感染,检出55株病原菌,以幽门螺杆菌为主,共36株占65.5%;logisic多因素回归分析结果显示,内镜消毒时间不足、检查室空气消毒不符合标准、检查人员手卫生不到位、内镜消毒不符合要求是消化道内径检查发生感染的独立危险因素(P<0.05)。结论幽门螺杆菌、假单胞菌属和沙门菌属是医院感染的主要病原菌,避免医院感染发生的危险因素,降低医院感染的发生率,保证患者和医疗工作者的安全是目前急需解决问题。OBJECTIVE To investigate the situation of infections due to gastrointestinal endoscopy, in order to understand the main risk factors of the infections and provide reference for clinical treatment. METHODS Totally 697 inpatients undergoing routine gastrointestinal endoscopy from Mar. 2000 to Dec. 2011 were enrolled. The pathogenic bacterial culture was performed for those infected patients due to the endoscopy. Results were statistically analyzed using SPSS 16.0. RESULTS Infections occurred in 55 cases, totally 55 pathogenic strains were detected, dominated by Helicobacter pylori （36 strains, 65.5 %）. The multivariate logistic regression analysis showed deficiency of sterilization time for endoscopes, unqualified air sterilization in examining rooms, insufficient hand hygiene of examiners and unqualified sterilization of endoscopes were independent risk factors （P 〈 0. 05）. CONCLUSION Helicobacter pylori, Pseudomonas and Salmonella are the main pathogenic bacteria of hospital infections. At present, avoidance of the risk factors of hospital infections and reduce of the incidence of infections are the urgent issues to be solved to ensure safety of patients and medical workers.
