不同清洗方法对胃镜清洗效果的研究

目的对比不同清洗方法清洗胃镜的效果，探讨实用可靠的胃镜清洁度的评价方法。方法选择3种不同方法清洗胃镜。使用Endocheck管腔洁净测试组检测清洗后胃镜的清洁度，对比不同清洗方法清洗胃镜的效果。结果常规方法清洗胃镜后管腔残留物经测试合格率为50．0％，经提高清洗用多酶浓度与加床旁预洗处理，合格率分别升至60．0％和73．3％，其中加床旁预洗处理后的合格率与常规方法比较差异有统计学意义（P〈0．05）。结论床旁预洗处理可以提高胃镜管腔的清洁度，Endoeheek类产品可以作为胃镜管腔清洁度的一种评价方法。

Evaluation of different cleaning methods on the cleaning effect of gastroscope

Objective This study compared the cleaning effect of gastroscope by different cleaning mehtods and discuss practical and reliable evaluation method for the cleaning degree of gastro- scope. Methods Three cleaning methods were selected and used in the cleaning of gastroscope.The Endocheck lumen was used to examine the cleaning degree of gastroscope and the effects of different methods were compared. Results The qualification rate by using ordinary cleaning method was 50.0% and it reached 60.0% and 73.3% by elevation of polyenzyme concentration and adding bedside pre-washing,which was statistically different from that by using ordinary cleaning method （P 〈 0.05）. Conclusions Bedside pre-washing could increase the cleaning degree of gastroscope;Endocheck lumen could be regarded as an evaluation method for the cleaning degree of gastroscope.
