医疗器械清洗中多酶清洗液与碱性清洗液保湿处理效果比较

目的：探讨多酶清洗液与碱性清洗液保湿对使用后手术器械的清洗效果。方法选取2013年6-9月手术室剖宫产使用后的手术器械1200件，立即回收，采用随机数字表法将器械分为Ⅰ、Ⅱ、Ⅲ、Ⅳ组，每组300件。其中Ⅰ组采用多酶清洗液保湿2 h后清洗；Ⅱ组采用多酶清洗液保湿12 h后清洗；Ⅲ组采用碱性清洗液保湿2 h后清洗；Ⅳ组采用碱性清洗液保湿12 h后清洗，比较各组器械的清洗合格率。结果保湿2 h，多酶清洗液（Ⅰ组）、碱性清洗液（Ⅲ组）目测、镜下及试纸检测器检测器械清洗合格率比较，差异无统计学意义（P＞0．05）。保湿12 h，碱性清洗液（Ⅳ组）目测合格292件（97．33％），镜下合格289件（96．33％），试纸检测合格291件（97．00％），分别高于多酶清洗液（Ⅱ组）的261件（87．00％），259件（86．33％），259件（86．33％），差异有统计学意义（χ2值分别为18．690，18．950，14．592；P＜0．01）。采用多酶清洗液2 h（Ⅰ组）目测合格296件（98．67％），镜下合格294件（98．00％），试纸检测合格295件（98．33％），分别明显高于12 h （Ⅱ组），差异有统计学意义（χ2值分别为30．688，22．017，30．513；P＜0．01）；采用碱性清洗液2 h（Ⅲ组）与12 h（Ⅳ组）保湿处理后检测器械清洗合格率比较，差异均无统计学意义（ P＞0．05）。结论对正常使用后的手术器械宜在2 h内及时清洗，采用多酶清洗液或碱性清洗液保湿均可以确保清洗质量；不能在2h内回收清洗的器械，宜先采用碱性清洗液保湿处理，再使用机洗的清洗方法，以有效提高器械清洗质量。

Effect comparison between multiple enzymes cleaning fluid and alkaline cleaning fluid in the cleaning of moisturizing medical equipment

Objective To explore the cleaning effect of moisturizing through multiple enzymes cleaning fluid or alkaline cleaning fluid in the cleaning of medical equipment .Methods One thousand and two hundred surgical instruments used by cesarean delivery and recycled immediately from June 2013 to September 2013 were chosen and divided into the Ⅰ,Ⅱ,Ⅲ,Ⅳgroup according to the random number table , each with 300 .the ⅠandⅡgroup received the cleaning 2, 12 h after the moisturizing through the multiple enzymes cleaning fluid , respectively;and Ⅲ and Ⅳ group received the cleaning 2, 12 h after the moisturizing through the alkaline cleaning fluid , respectively .The qualification rates of cleaning were compared among the groups .Results No differences were found in the qualification rates of cleaning through the visual , microscopically and test paper detection between Ⅰ and Ⅲ groups （ P 〉0.05 ）.The qualification rates of cleaning through the visual , microscopically and test paper detection were respectively 97.33% （292/300）,96.33% （289/300） and 97.00%（291/300） in Ⅳ group, and were higher than 87.00% （261/300）,86.33% （259/300） and 86.33%（259/300） in Ⅱ group, and the differences were statistically significant （χ2 =18.690,18.950, 14.592, respectively;P〈0.01）.The qualification rates of cleaning through the visual , microscopically and test paper detection were respectively 98.67% （296/300）,98.00% （294/300） and 98.33% （295/300） in Ⅰgroup, and were higher than those of Ⅱgroup, and the differences were statistically significant （χ2 =30.688, 22.017,30.513, respectively;P 〈0.01）.No differences were found in the qualification rates of cleaning betweenⅢandⅣgroups （P〉0.05）.Conclusions The surgical instruments after the normal use should be cleaned within 2 hours, and the moisturizing through multiple enzymes cleaning fluid or alkaline cleaning fluid can all ensure the cleaning quality .The surgical instruments after the use can not be cleaned with
