脉动真空清洗消毒器对腔镜器械的清洗效果研究

Cleaning effect of pulsating vacuum washer-disinfector on endoscopic instruments

目的探讨脉动真空清洗消毒器的清洗效果、干燥质量、处理时间和装载量。方法将2021年7—12月某医院消毒供应中心(CSSD)回收的术后腔镜器械随机平均分为对照组和试验组,经预处理后分别采用喷淋清洗消毒器和脉动真空清洗消毒器进行清洗消毒干燥。采用目测法、杰力试纸法和ATP生物荧光法检测清洗效果,目测法检测干燥质量。比较两组清洗效果、干燥质量、处理时间和装载量。结果与对照组相比,试验组杰力试纸合格率和干燥合格率高(χ~2=4.000和33.063,P<0.05),腔镜吸引器的RLU值低(t=-3.566,P=0.001),处理时间短(t=-6.242,P<0.001),且相同腔镜器械一锅次装载量多(6套vs 2套)。结论脉动真空清洗消毒器的清洗和干燥质量较好,且处理时间短和装载量多,可提高腔镜器械清洗的工作效率和周转效率。

Objective To investigate the cleaning effect,drying quality,processing time and loading capacity of pulsating vacuum washer-disinfector for endoscopic instruments.Methods The postoperative endoscopic instruments recovered from CSSD of a hospital from July to December 2021 were equally divided into control group and test group according to randomized block,and were cleaned,disinfected and dried by spray washer-disinfector and pulsating vacuum washer-disinfector,respectively.The cleaning effect was observed by visualization,Lustration test and ATP biofluorescence.The drying quality was detected by visual inspection.Washing effects,drying quality,treatment time,and loading capacity were compared between the two groups.Results Compared with the control group,the test group had high Lustration test pass rate and drying pass rate(χ~2=4.000 and 33.063,P0.05),low RLU value(t=-3.566,P=0.001),short processing time(t=-6.242,P0.001),and the higher load of the same endoscopic instruments in one time(6 sets vs 2 sets).Conclusion The cleaning and drying quality of the pulsating vacuum washer-disinfector is better,and the processing time and the loading capacity are short,which can improve the working efficiency and turnover efficiency of endoscopic instrument cleaning.
