摘　　要：目的 评价不同干燥储存方式对软式内镜干燥及储存效果的影响,为临床选择合适的干燥及储存方式提供参考依据。方法 采用便利抽样法抽取112条内镜,内镜经标准化再处理步骤后随机分为气枪吹扫组和乙醇灌注气枪吹扫组,干燥不同时间(0.5、1、3和5 min)后置于自动柜和标准柜中,并设置不同储存时间(0、3、12、24、48、72和168 h),采用氯化钴试纸观察内镜管腔干燥合格情况,微生物学检测观察内镜的消毒合格情况。结果 2组内镜干燥不同时间后均无法清除所有内镜管腔内残留液体,其中干燥0.5 min内镜置于标准柜中储存168 h后仍有液体残留现象,置于自动柜储存3 h后无液体残留。2组内镜在标准柜储存24 h后均出现微生物阳性结果,在自动柜储存72 h后微生物学检测阳性检出率均为0%,其中乙醇灌注气枪吹扫组内镜在自动柜储存168 h后阳性检出率均为0%。logistic回归分析显示,乙醇灌注气+枪吹扫干燥、自动柜储存和延长干燥时间为内镜消毒效果的保护因素。结论 自动柜储存时增加了内镜储存的安全性。Objective To evaluate the effects of different drying and storage methods on flexible endoscopy,and to provide reference for clinical selection of appropriate drying and storage methods.Methods A total of 112 endoscopes were selected by convenient sampling method.After standardized reprocessing steps,the endoscopes were randomly divided into two groups,air gun purging group and ethanol perfusion air gun purging group.The endoscopes were dried for 0.5,1,3,5 min respectively,and then placed in automatic cabinets and standard cabinets,and stored for 0,3,12,24,48,72 and 168 h.The qualified condition of endoscope lumen drying was observed by cobalt chloride test paper,and the qualified condition of endoscope disinfection was observed by microbiological monitoring.Results The two groups could not remove all the residual liquid in the endoscope lumen after the endoscope was dried for different time.There was still liquid residue after the endoscope was dried for 0.5 min and stored in the standard cabinet for 168 h.There was no liquid residue after the endoscope was stored in the automatic cabinet for 3 h.Two groups showed positive microbial results after 24 h storage in the standard cabinet,and the positive microbial detection rate after 72 h storage in the automatic cabinet was 0%,and the positive detection rate of the ethanol perfusion air gun purging group was 0% after 168 h storage in the automatic cabinet.Logistic regression analysis showed that alcohol injection air gun purging and drying,automatic cabinet storage and prolonged drying time were protective factors for endoscope disinfection effect.Conclusion Automatic drying storage cabinet can increase the safety of endoscope storage.
