软式内镜管道自动清洗装置对消化内镜消毒质量的影响

Effect of flexible endoscope channel automated brushing system on disinfection quality of digestive endoscope

目的评价软式内镜管道自动清洗装置对消化内镜消毒质量的影响。方法选取某医院消化内镜中心160条胃肠镜检查后的内镜作为研究对象,运用区组随机化的方法,将内镜按照1∶1的比例随机分配至试验组和对照组。在内镜管道刷洗阶段,试验组内镜采用软式内镜管道自动清洗装置刷洗内镜,对照组内镜采用清洗消毒员手工刷洗内镜。比较两组内镜的消毒合格率、内镜管道刷洗时间及清洗消毒员躯体疲劳程度等指标的差异。结果试验组内镜总体消毒合格率(98.75%)高于对照组(88.75%,P=0.009),其中试验组胃镜消毒合格率高于对照组(98.33%VS 86.89%,P=0.016),肠镜消毒合格率两组比较,差异无统计学意义(100%VS 90.00%,P=0.299)。试验组内镜管道刷洗时间长于对照组[(158.76±17.46)s VS(117.44±13.59)s,P<0.001]。试验组刷洗前后清洗消毒员躯体疲劳程度得分差值低于对照组[(0.87±0.80)分VS(2.84±1.08)分,P<0.001],其中刷洗前清洗消毒员躯体疲劳程度得分两组比较,差异无统计学意义[(1.23±0.50)分VS(1.20±0.46)分,P=0.743];试验组刷洗后清洗消毒员躯体疲劳程度得分低于对照组[(2.10±1.13)分VS(4.04±1.36)分,P<0.001]。结论软式内镜管道自动清洗装置可提高内镜消毒质量,减轻清洗消毒员躯体疲劳程度。

Objective To evaluate the effect of flexible endoscope channel automated brushing system on the disinfection quality of digestive endoscopes.Methods 160 pieces of endoscopes after gastroenteroscopy in the digestive endoscopy center of a hospital were chosen.According to the blocked randomization method,endoscopes were randomly assigned to the experimental group and the control group in a ratio of 1∶1.During the endoscope channel brushing,endoscopes in the experimental group were brushed with flexible endoscope channel automated brushing system,while endoscopes in the control group were cleaned manually by cleaning and disinfection personnel.Diffe-rences in disinfection qualification rate of endoscopes,brushing time of endoscope channels,and physical fatigue of cleaning and disinfecting personnel between the two groups were compared.Results The overall qualification rate of endoscope disinfection in the experimental group was higher than that in the control group(98.75%vs 88.75%,P=0.009),with the qualification rate of gastroscope disinfection in the experimental group being higher than that in the control group(98.33%vs 86.89%,P=0.016).There was no statistically significant difference in the qualification rate of enteroscope disinfection between two groups(100%vs 90.00%,P=0.299).The brushing time of the endoscope channel in the experimental group was longer than that in the control group([158.76±17.46]seconds vs[117.44±13.59]seconds,P<0.001).The difference in physical fatigue scores of the cleaning and disinfection personnel before and after brushing in the experimental group was lower than that in the control group([0.87±0.80]points vs[2.84±1.08]points,P<0.001),there was no statistically significant difference in the physical fatigue scores of the cleaning and disinfection personnel before brushing between the two groups([1.23±0.50]points vs[1.20±0.46]points,P=0.743);the physical fatigue scores of the cleaning and disinfection personnel after brushing in the experimental group were lower than that in the control group([2.10±1.13]points vs[4.04±1.36]points,P<0.001).Conclusion The flexible endoscope automated channel brushing system can improve the quality of endoscope disinfection and reduce the physical fatigue of cleaning and disinfection personnel.
