采用不同清洗方法的手术器械清洗质量的对比

目的探讨医院手术器械有效的清洗方法,以提高清洗质量,保证灭菌效果,有效控制医院感染。方法选择消毒供应中心回收污染器械1080件,分为3组,每组齿牙类器械300件,管腔类器械60件,分别接受直接机洗(A组)、酶泡+机洗(B组)、预洗+酶泡+超声+机洗(C组)进行清洗,评价清洁合格率并进行对比。结果 A组、B组、C组的合格率分别为81.1%、92.8%、96.9%,三组间及两两组间的差异均有统计学意义(均P<0.01)。结论预洗+酶泡+超声+机洗的器械清洗方法的清洁效果明显优于其他两种方法。

A comparative study on the cleaning quality of surgical instruments using different cleaning methods

Objective To explore the effective methods for surgical instruments cleaning and ensure the sterilization effect and the control of hospital infections.Methods A total of 1080 pieces of contaminated surgical instruments were selected from Central Sterile Supply Department.Those surgical instruments were assigned into 3 groups,each group included 300 pieces of tooth type devices and 60 pieces of lumen devices.Direct machine washing,enzyme dipping ＋ machine washing and pre-washing ＋ enzyme dipping ＋ ultrasound ＋ machine washing were used to the 3 groups,respectively.The qualification rates of the 3 groups were evaluated.Results The qualification rates were 81.1%,92.8% and 96.9%,respectively in the 3 groups.The difference among the 3 groups was statistically significant（P 0.01）.Conclusion The effect of pre-washing ＋ enzyme dipping ＋ ultrasound ＋ machine washing cleaning method is remarkably superior to the other two methods.
