摘　　要：目的探讨软式内镜活检管腔的干燥方法和干燥时间。方法将临床诊疗使用过的胃镜随机分为5组,结肠镜随机分为6组,每组均进行60次实验。所有胃镜和结肠镜经规范清洗和消毒后,第1组活检管腔常规使用压力气枪持续吹气30 s进行干燥;剩余各组先用内镜干燥机干燥5 min,再使用压力气枪对活检管腔持续吹气30、40、50、60 s(胃镜)或30、40、50、60、70 s(结肠镜)。干燥时间结束时,使用氯化钴试纸判断内镜管腔的干燥程度。结果胃镜常规吹气30 s的干燥合格率为20.0%,结肠镜为18.3%;胃镜干燥机干燥5 min+吹气60 s,结肠镜干燥机干燥5 min+吹气70 s,干燥合格率均为100%;胃镜、结肠镜各组组内干燥合格率比较,差异有统计学意义(均P<0.05)。结论软式内镜用内镜干燥机干燥5 min的基础上,胃镜活检管腔吹气时间60 s,肠镜活检管腔吹气时间70 s,可以保证内镜活检管腔的干燥效果。Objective To investigate the drying methods and optimal time for internal suction biopsy channel dryness for flexible endoscope.Methods Flexible gastroscopes or colonoscopes after clinical use were randomized into 5 or 6 groups.After standard reprocessing steps,drying was performed either manually(forced high-efficiency particulate filtered air with a Safety Air Gun for 30 seconds)or was automated(endoscope drying device)for 5 minutes and then added manual drying for either 30,40,50,60 or 70 seconds(the 6th group of the colonoscope).The experiments repeated 60 times for each group.Drying effectiveness was measured using cobalt chloride paper after drying.Results The rate of dryness using manual drying was 20.0%for gastroscope and 18.3%for colonoscope.The rate of dryness for gastroscope achieved 100%at 60 s of manual drying on the basis of automated drying,or at 70 s for colonoscope.The dryness rates among different gastroscope groups and colonoscope groups had significant differences(both P<0.05).Conclusion Using automated drying for 5 minutes,internal suction biopsy channel can achieve dryness by adding manual drying for either 60 seconds for the gastroscope or 70 seconds for the colonoscope.
