【摘要】：目的对临床使用消化内镜消毒存放后细菌污染状况进行调查监测,了解内镜存放后细菌学指标以及不同存放环境对内镜细菌数的影响。方法 2012年11月-2013年6月对消毒后胃镜、肠镜进行采样检测;随机放置于镜房、镜柜内,存放15、63h后,再次对内镜进行采样检测;同时,监测镜房、镜柜内温度、湿度,空气及物体表面细菌菌落数。结果存放后内镜共采样174份,细菌超标9份,超标率为5.17%,超标9份均为存放63h后内镜,存放15h内镜全部合格,未检出致病菌;镜房空气、物体表面、内镜表面合格率分别为93.60%、97.80%、96.59%,镜柜空气、内镜表面合格率均为100.00%,内镜合格率为93.02%。结论消毒后内镜存放15h细菌超标率极低,使用前不用再次消毒;若存放时间≥63h,则存在细菌数超标,建议使用前应进行消毒,镜房、镜柜均可用于内镜存放,但应对存放条件进行监控。
[Abstract]:Objective to investigate and monitor the bacterial contamination after disinfection and storage of digestive endoscopy in clinic, and to understand the effect of different storage environment on the bacterial number of endoscope.Methods from November 2012 to June 2013, the gastroscope and enteroscopy were sampled and tested, and then the endoscope was sampled and tested again after 1563 hours of storage in the mirror room and cabinet, and the temperature and humidity in the mirror room were monitored, and the temperature and humidity in the mirror room were monitored.Number of bacterial colonies on air and object surfaces.Results A total of 174 samples of endoscopy were collected after storage, 9 samples of bacteria exceeded the standard, the rate of exceeding the standard was 5.17, and 9 samples exceeded the standard for 63 hours after storage, all the endoscopes were qualified after storage for 15 hours, no pathogenic bacteria were detected, the air in the mirror room, the surface of the object, and the surface of the object were not detected.The qualified rate of endoscope surface was 93.60% and 97.80% respectively. The qualified rate of air and surface of mirror cabinet was 100.000.The qualified rate of endoscopy was 93.02%.Conclusion the rate of bacteria exceeding the standard for 15 hours after disinfection is very low and no re-disinfection is necessary before use. If the storage time is more than 63 hours, the number of bacteria will exceed the standard. It is suggested that disinfection should be carried out before use, and both the mirror room and the mirror cabinet should be used for endoscope storage.However, storage conditions should be monitored.
