采用酸性氧化电位水的内镜消毒机对纤维支气管镜消毒效果研究

目的：探讨以酸性氧化电位水的内镜消毒机对纤维支气管镜的消毒效果。方法将重庆医科大学附属第一医院重症医学科诊疗后污染的纤维支气管镜460根，随机分为试验组（采用酸性氧化电位水为消毒剂的内镜清洗消毒机对支气管镜消毒）和对照组（以2％戊二醛为消毒剂的传统五槽清洗消毒法），分别从内镜表面清洁度、镜身表面附着物、管道堵塞及细菌菌落检测等方面进行评价。结果试验组在内镜表面清洁度、镜身表面附着物、管道堵塞等方面均较对照组效果好；无论是内腔采样法还是外表采样法，试验组的无菌生长例数均高于对照组；试验组合格率均明显高于对照组，差异有统计学意义（P＜0．05）。结论应用酸性氧化电位水为消毒剂的全自动内镜消毒机明显提高了纤维支气管镜清洗、消毒的质量，同时减轻了人为的劳动强度，值得推广。

The disinfection effect of the endoscope disinfection machine with acidic oxidizing potential water on the fiber bronchoscopy

Objective To investigate the disinfection effect of the endoscope disinfection machine with acidic oxidizing poten‐tial water on the fiber bronchoscopy .Methods Totlly 460 cases of contamination after diagnosis and treatment in the department , were randomly divided into experimental group (using electrolyzed oxidizing water as disinfectant ;according to the cleaning and dis‐infection of endoscope Koeman brand ECM‐03A type machine bronchoscope disinfection) and control group (with 2% glutaralde‐hyde disinfectant of the traditional five tank cleaning disinfection method ) ,evaluation of endoscopic surface cleanliness ,surface at‐tachment ,pipe blockage and bacterial colony detection .Results The experimental group was better than the control group in the aspects of endoscopic surface cleanliness ,mirror surface attachment ,pipe blockage and so on ;The number of sterile growth in the experimental group was higher than that in the control group ,both in the inner cavity sampling method and the outside sampling method .The number of cases of ≥20 CFU/piece in the experimental group was significantly less than that in the control group , with the cavity sampling method ,the qualified rate of the experimental group was also significantly higher than that of the control group ,the difference was statistically significant (P< 0 .05) .Conclusion The application of acidic oxidizing potential water as a disinfectant in the whole automatic endoscope disinfection machine significantly improve the quality of cleaning and disinfection ,at the same time ,and reduce human labor strength ,improve the application efficiency of fiber bronchoscopy ,worthy of promotion .
