75%乙醇预处理对关节置换手术器械骨水泥超声波清洗效果的影响
Effect of 75%ethanol pretreatment on the ultrasonic cleaning quality of bone cement-contaminated instruments used for joint replacement surgery
摘要
Abstract
Objective To investigate the effect of 75%ethanol pretreatment on the ultrasonic cleaning quality of bone cement-contaminated instruments used for joint replacement surgery.Methods A total of 699 bone cement-contaminated instruments used for joint replacement were randomly assigned to the control group(n=349)and the observation group(n=350).They were pretreated by soaking in water and 75%ethanol for 60 minutes,respectively,followed by ultrasonic cleaning.The residual cement rate,cleaning compliance rate,cleaning time and cleaning satisfaction score of the instruments between the two groups were compared.Results The residual cement rate of instruments after pretreatment in the observation group was significantly lower than that in the control group(P<0.05).Both visual inspection and ATP fluorescence assay showed that the cleaning compliance rate of instruments in the observation group was significantly higher than that in the control group(P<0.05).The cleaning time of instruments in the observation group was significantly shorter than that in the control group(P<0.05).Instruments of the observation group had significantly higher cleaning satisfaction scores in terms of pretreat-ment operation,cleaning convenience,instrument performance maintenance and facilitation of disinfection and sterilization than those in the control group(P<0.05).Conclusion For bone cement-contaminated instruments for joint replacement,pretreatment with soaking in 75%ethanol for 60 minutes can improve the ultrasonic cleaning quality,shorten cleaning time and improve cleaning satisfaction score.关键词
