超声波清洗机在腔镜手术器械清洗消毒中的应用效果研究

Study of effect ofultrasonic cleaners on endoscopic instrument

目的:探讨超声波清洗机在腔镜手术器械清洗消毒中的应用效果。方法:选取2015年我科从手术室收回的160套腔镜手术器械.随机分为对照组和观察组各80套,对照组采用手工清洗;观察组采用手工清洗加超声波清洗。采取目测清洁度、管腔的检查-注入95%酒精用气枪将管腔内95%酒精吹向洁净的白色纱布上(纱布洁净如初)以及器械隐血试验(OB)对比分析两组腔镜手术器械的清洗效果。结果:目测清洁度、管腔的检查-注入95%酒精用气枪将管腔内95%酒精吹向洁净的白色纱布上(纱布洁净如初)、观察组合格率为96.25%,对照组合格率为85%;腔镜手术器械OB实验,观察组阴性率为93.75%,对照组阴性率为82.5%。观察组的目测清洁度、管腔的检查-注入95%酒精用气枪将管腔内95%酒精吹向洁净的白色纱布上(纱布洁净如初)和OB实验阴性率均高于对照组.差异具有统计学意义(P<0.05)。结论:超声波清洗机结合酶液有效温度清洗能够高效清洗腔镜手术器械。

[Objective]To discuss the effect of ultrasonic cleaners on endoscopic instrument.Methods：1 60 sets of endoscopic instruG ment recycled from operating room in our department from Jan.,201 5 to Dec.,201 5 were divided into control group and observation group randomly,80 sets in each group.Control group were cleaned by manual cleaning.Observation group were cleaned by manual cleaning combined with sonicleaning.Cleanliness by visual inspection,examination of lumen- injected 95% alcohol were blew to clean white gauze by air gun （gauze was clean as before）and occult blood test（OB）on instrument were used to analyze the cleaning effect of two groups.Results：Cleanliness by visual inspection and examination of lumen- injected 95% alcohol were blew to clean white gauze by air gun （gauze was clean as before）showed that percent of pass of observation group was 96.25%,percent of pass of control group was 85%.OB test on instrument showed that negativity rate of observation group was 93.75%,negativity rate of control group was 82.5%.The cleanliness by visual inspection,examination of lumen- injected 95% alcohol were blew to clean white gauze by air gun （gauze was clean as before）and OB test in observation group were higher than control group’s,the differences were statistically sigG nificant（P〈0.05）.Conclusion：Ultrasonic cleaners combined with enzyme liquid in effective temperature could efficient cleaning endoG scopic instrument.
