目的了解不同方法清洗医疗器械和不同清洗剂清洗后进行消毒的效果,以确定更好的器械清洗方法。方法对污染器械分别使用多酶清洗液(Ⅰ组)、含氯医疗器械清洗液(Ⅱ组)和无菌水(Ⅲ组)3种方法进行浸泡后清洗,采用目测法和五倍光源放大镜观察法对清洗效果进行评价,清洗后使用戊二醛进行浸泡消毒,清洗后参照2002年版《消毒技术规范》4.7.4.1.3的检测方法对器材进行采样,比较检测结果。结果使用多酶清洗液清洗合格率,Ⅰ组目测与五倍光源放大镜观察均为100.0%;使用含氯消毒剂清洗浸泡的Ⅱ组目测率为100.0%,五倍光源放大镜观察为97.5%;使用水洗的Ⅲ组目测合格率为90.0%、五倍光源放大镜观察为75.0%;经过戊二醛清洗后酶洗组的消毒效果最好,含氯消毒剂清洗组次之,水洗组效果最差,水洗组所用戊二醛消毒液连续使用天数最短。结论使用多酶清洗剂清洗医疗器械较其他两种清洗方法优势明显。
Objective To understand the effectiveness of different methods of disinfecting medical devices and different cleaning agents to determine better device cleaning methods. Methods The contaminated instruments were immersed and cleaned with multi-enzyme cleaning solution (group Ⅰ), chlorine-containing medical device cleaning solution (group Ⅱ) and sterile water (group Ⅲ) respectively. Visual inspection and five-times magnifying glass Law on the cleaning effect evaluation, after cleaning using glutaraldehyde for soaking disinfection, after cleaning reference to the 2002 edition of “disinfection technical specifications” 4.7.4.1.3 detection methods of equipment sampling, comparison test results. The results of the use of multi-enzyme cleaning solution cleaning pass rate, visual acuity and five times the light source group I were 100.0% magnifying glass; chlorine disinfectant cleaning immersion group II visual test was 100.0%, five times the light source magnifying glass was 97.5% Water-washed group Ⅲ visual pass rate of 90.0%, five times the light source magnifying glass was observed 75.0%; After glutaraldehyde cleaning enzyme disinfection effect is best, followed by chlorine disinfectant cleaning group, the worst effect of washing group, Washed group glutaraldehyde disinfectant used the shortest number of days of continuous use. Conclusions The use of multi-enzyme cleaning agents to clean medical devices has obvious advantages over the other two cleaning methods.
