三种显微手术器械清洗方法的效果比较

目的：探讨显微手术器械最佳的清洗方法，以提高清洗效果。方法于2013年2—10月将眼科和手外科显微手术使用后的1350件器械随机分为对照组、浸泡组和振洗组，每组各450件。3组器械分别做清洗处理，对照组器械不做预处理，浸泡组器械在多酶清洗液中浸泡10 min，振洗组器械在含多酶清洗液的数控超声波清洗机中浸泡超声波振洗10 min，然后将3组器械均置于全自动清洗消毒机使用轻型循环清洗。采用目测法和放大镜检测法检查清洗效果。结果目测法检查对照组、浸泡组、振洗组清洗质量合格件数分别为341，402，439件，合格率分别为75．78％，89．33％，97．56％；放大镜检查合格件数分别为319，381，428件，合格率分别为70．89％，84．67％，95．11％，振洗组合格率明显高于对照组和浸泡组，差异均有统计学意义（χ^2值分别为99．8946，96．6823；P＜0．01）。结论在多酶清洗液中超声振洗后再使用全自动清洗消毒机清洗可提高清洗效果，是显微手术器械理想的清洗方法。

Effect evaluation of three different cleaning methods on microsurgical instruments cleaning

Objective To discuss the best way of microsurgical instruments cleaning to improve the cleaning effect .Methods Based on random principle , the ophthalmic and hand surgery microsurgery instruments were divided into three groups （ control group ,soak group and oscillation of washing group ,each group 450 cases）after being used.The general group was cleaned directly without primary treatment ,soak group used multienzyme abluent and oscillation of washing group used ultrasonic cleaning respectively .Then all the three groups were cleaned by gentle cycle of automated Multi-chamber Washer .The cleaning effects were checked and compared by single eyeballing and magnification inspected .Results It was found that qualification numbers of the three groups by single eyeballing was 341,402 and 439, with qualification rates 75.78%,89.33% and 97.56%respectively .and qualification numbers by magnification inspected was 319, 381 and 428, and that qualification rates were 70.89%,84.67%and 95.11%, respectively.The qualified rates of oscillation of washing group were higher than that of other two groups , the differences were statistically significant （χ^2 =99.894 6, 96.682 3, respectively;P〈0.01）.Conclusions The ideal method of microsurgical instruments cleaning is use the automated Multi-chamber Washer after soaking in multienzyme abluent and using Ultrasonic cleaning .
