摘要
目的:对腹腔镜手术器械使用负压脉动清洗消毒器的应用效果进行探讨。方法:选取440件腹腔镜手术器械,经2023年7月~2023年12月本院手术室使用回收后,随机分为观察组和对照组,每组220件。对照组采用人工清洗与超声清洗相结合的方式进行,观察组则采用负压脉动清洗消毒器进行清洗。清洗效果的评估采用三种方法:8倍带光源放大镜法、白通条检测法、残留蛋白检测法。结果:通过8倍带光源放大镜目测法测试,对照组合格率为96.82%,观察组合格率为99.55%,统计学分析显示两者差异明显(χ2=4.583,P=0.032)。采用白通条检测法检测后发现,对照组合格率为95.45%,观察组合格率为98.64%,两者之间的差异在统计学上是有意义的(χ2=3.884,P=0.049)。经对残留蛋白检测方法检测,对照组合格率为92.27%,观察组合格率为96.82%,经统计学分析发现差异显著(χ2=4.407,P=0.036)。结论:采用负压脉动清洗消毒器比采用人工清洗与超声清洗相结合的方式清洗效果更好,可以更有效地清洗已使用的腹腔镜器械。
Objective:To discuss the effect of negative pressure in laparoscopic surgical instruments.Methods:440 laparoscopic surgical instruments were selected and recovered in the operating room of our hospital from July 2023 to December 2023.220 pieces were randomly divided for observation group and control group.The control group used manual cleaning and ultrasonic cleaning,while the observation group used negative pressure pulse cleaning and sterilizer for cleaning.The cleaning effect was evaluated by three methods:8 times magnification method with light source,white pass strip detection method,and residual protein detection method.Results:By 8 times,the control group was 96.82%and the observation group was 99.55%.The statistical analysis showed that the difference was obvious(χ2=4.583,P=0.032).After using the white pass test,the pass rate was 95.45%and the observation group was 98.64%.The difference between the two was statistically significant(χ2=3.884,P=0.049).After the detection of residual protein,the qualified rate of control group was 92.27%,and the qualified rate of observation group was 96.82%,with significant differences(χ2=4.407,P=0.036).Conclusion:The negative pressure pulsation cleaning sterilizer is better than the combination of manual cleaning and ultrasonic cleaning,and can more effectively clean the used laparoscopic instruments.
