| 目的 为寻找安全、无毒、高效的胃镜消毒方法，本文探讨应用氧化电位水（ＥＯＷ） 消毒胃镜的效果。方法 对临床污染的５０ 支胃镜进行现场消毒试验。胃镜经去有机物处理后，以ＥＯＷ 生成机制备的ＥＯＷ 原液〔氧化还原电位（ＯＲＰ）１ １００ｍ Ｖ，ｐＨ２.７,有效氯４０ ～５０ｍｇ／Ｌ〕分别浸泡消毒５ｍｉｎ、１ｍｉｎ。于消毒前后共采样１６０ 例次。结果 ＥＯＷ 对胃镜表面自然菌杀灭率５ｍｉｎ 、１ｍｉｎ 组分别为９９.９４ ％ 、９９.８９ ％,１ｍｉｎ 组腔内杀灭率为９８.８０ ％,平均每件杀灭率为９９.５４ ％。结论 在彻底清除胃镜内、外有机物后，用ＥＯＷ 浸泡１ｍｉｎ，能迅速杀灭微生物且因其无毒性残留可省去无菌水冲洗步骤，为临床安全、有效、便捷的消毒方法，经观察３５０ 例对胃镜无损害 |

| Objective In order to find a method of disinfection for gastroscope which is supposed to be safe, less toxic and highly efficient, EOW was chosen for gastroscope disinfection in our hospital. Method Gastroscope was first washed with neutral liquids which were equally mixed by acid and alkaline water produced by EOW machine. It was then immersed in EOW(ORP 1 100 mV,pH 2.7,effective chlorine 40-50mg/L) for 1 and 5 minutes. A total number of 160 samples were collected. Results The killing rate for natural bacteria was 99.94% in 5-minute group. In 1-minute group, the rate were 99.89% and 98.80% on the surface and inside of the gastroscope. The average killing rate was 99.54%. Conclusion It appeared to be a safe, effective and simple method for disinfection after termination of gastroscope. It could be directly used on patient without washing with aseptic water. No damage to the gastroscope was found. |
