摘　　要：目的:分析不同灭菌技术在管腔类手术器械管理中的应用效果。方法:在医院手术器械中,选取2022年10月~2023年10月消毒供应室提供的管腔类手术器械100件作为研究对象,采用数字表法随机分为Ⅰ组与Ⅱ组,每组件数50件,均采用相同的清洗方法,清洗后进行灭菌,Ⅰ组采用低温过氧化氢等离子灭菌,Ⅱ组采用脉动真空压力蒸汽灭菌。对比两组手术器械灭菌时间、灭菌温度,并比较两组器械清洗后不同时间点的灭菌效果和保存3个月、6个月、7个月、8个月、9个月的细菌生长情况。结果:Ⅰ组灭菌时间长于Ⅱ组,灭菌温度低于Ⅱ组(P<0.05)。Ⅰ组手术器械在清洗后4h、6h灭菌合格率低于Ⅱ组(P<0.05)。两组管腔类手术器械保存6个月,ATP荧光检测均未见RLU值超标,灭菌效果均合格,但保存7个月开始,Ⅱ组的管腔类手术器械ATP荧光检测的合格率逐渐降低,且低于Ⅰ组(P<0.05)。结论:低温过氧化氢等离子对管腔类手术器械的灭菌远期效果较理想,还避免高温高压消毒对管腔类手术器械的损伤。Objective:The application effect of different sterilization techniques in the management of luminal surgical instruments was analyzed.Methods:Among the hospital surgical instruments,100 luminal surgical instruments were selected as research objects,and randomly divided into group I and groupⅡby numerical table,with 50 pieces of each component sterilized by the same cleaning method,group I was sterilized by low temperature hydrogen peroxide plasma,and the groupⅡwas sterilized by pulsating vacuum pressure steam.The sterilization time and sterilization temperature of the two groups were compared,and the sterilization effect and the bacterial growth were compared for 3 months,6 months,7 months,8 months and 9 months.Results:Group I sterilization time was longer than the groupⅡ,and the sterilization temperature was lower than the groupⅡ(P<0.05).The sterilization qualification rate of group I instruments at 4h and 6h after cleaning was lower than the groupⅡ(P<0.05).The luminal surgical instruments were kept for 6 months,and the ATP fluorescence test did not exceed the RLU value,and the sterilization effect was qualified.However,since 7 months of preservation,the qualified rate of ATP fluorescence test of the luminal surgical instruments in the groupⅡgradually decreased,and it was lower than that in group I(P<0.05).Conclusion:The long-term sterilization effect of low temperature hydrogen peroxide plasma on luminal surgical instruments is ideal,and the damage of high temperature and high pressure disinfection on luminal surgical instruments is also avoided.
