摘　　要：目的对比分析超声波清洗机与手工清洗对内镜手术器械的清洗消毒效果。方法队列研究。抽取2021年11月至2023年12月郑州大学第一附属医院消毒供应室的300件内镜手术器械为研究资料, 按照随机数字表法将其分为对照组和研究组, 每组150件。对照组采用传统手工清洗法, 研究组采用超声波清洗机进行清洗。比较两组清洗消毒合格率[利用肉眼目测法、蛋白残留测定法和生物学发光检测法(ATP)进行评估]、清洗、消毒用时和成本。结果经肉眼目测观察, 研究组内镜中外表面合格率(96.00%, 144/150)及管腔内合格率(94.67%, 142/150)均高于对照组(13.33%, 20/150;8.00%, 12/150), P均<0.05。研究组蛋白残留测定法合格率(97.33%, 146/150)及ATP合格率(97.33%, 146/150)均高于对照组(87.33%, 131/150;82.67%, 124/150), P均<0.05。研究组清洗、消毒用时短于对照组, 清洗、消毒成本低于对照组(P<0.05)。结论相比手工清洗, 使用超声波清洗机清洗内镜手术器械效果更优, 不仅能提高清洗合格率, 且能缩短清洗消毒用时, 降低成本。Objective To compare the role of ultrasonic cleaning machine and manual cleaning in the cleaning and disinfection of endoscopic surgical instruments.MethodsA cohort study was conducted on 300 pieces of endoscopic surgical instruments which were selected from the Disinfection Supply Room of the First Affiliated Hospital of Zhengzhou University from November 2021 to December 2023.And the selected endoscopic surgical instruments were divided into the control group and the study group by random number table method,with 150 pieces in each group.The control group was cleaned by traditional manual cleaning method,while the study group was cleaned by ultrasonic cleaning machine.The qualified rate of cleaning and disinfection,evaluated by visual inspection,protein residue determination and adenosine triphosphate(APT)detection,the time and cost of cleaning and disinfection were compared between the two groups.ResultsBy visual observation with naked eyes,the qualified rates of the external surface and the lumen in the study group were 96.00%(144/150)and 94.67%(142/150),which were higher than the 13.33%(20/150)and 8.00%(12/150)in the control group(all P<0.05).The qualified rates of residual protein detection(97.33%,146/150)and ATP assay(97.33%,146/150)in the study group were higher than those in the control group(87.33%,131/150;82.67%,124/150),and the differences were significant(all P<0.05).The times for cleaning and disinfection of the study group were shorter than those of the control group,and the costs of cleaning and disinfection were lower than those of the control group(P<0.05).ConclusionsCompared with manual cleaning,using ultrasonic cleaning machine for cleaning of endoscopic surgical instruments is more effective,which can not only improve the cleaning qualification rate,but also shorten the cleaning and disinfection time,reduce costs.
