Objective To investigate and discuss the different pretreatment method washes department of gynecology instruments effect.Methods non-infectious 2 1 set of nature department of gynecology instru-ments parcels (53 pieces per package)with less than 2hs were used in the day after tomorrow,and was randomly allotted for 3 set:The alkali purges the agent group,multi-enzyme purges the agent group and contrast group,the collation group uses water in common use,Soaking 10mins respectively in advance be-fore the clear+enzyme purges 3 group in machine;Adopting visual measurement to carry out the compari-son cleaning effect with remains blood detecting.Results The alkali washes the agent and multi-enzyme cleaning an agent,visual measurement yield is 96.22% and 91.64%,Liang of group difference has no sta-tistics significance,but difference has statistics meaning comparing with collation group (P <0.05);Re-mains blood tests :The difference testing a group and contrasting set of comparison has statistics meaning (P <0.05).The alkali washes the agent and multi-enzyme cleaning parallel difference of agent group hav-ing statistics meaning (P <0.05).Conclusion The clear+enzyme washes front in machine,the pretreat-ment using an alkali to clean dose of apparatus being in progress can dislodge pollution such as proteide, fat kind effectively,washing using the department of gynaecology instruments effect is much better.%目的：探讨不同预处理方法清洗妇科器械的效果。方法使用2h以上的非感染性妇科器械包（每包53件）21套，随机分为3组：碱清洗组、多酶清洗组和对照组；碱清洗组采用碱性清洗剂、多酶清洗组采用全效多酶清洗剂、对照组用常用水，3组在机洗＋酶清洗前分别预浸泡10 min；采用目测和残余血检测进行清洗效果比较。结果碱清洗组和多酶清洗组，目测合格率为96．22％和91．64％，两组差异无统计学意义，但与对照组比较差异有统计学意义（P ＜0．05）；残余血测试：碱清洗组与多酶清洗组残余血测试结果均优于对照组，差异有统计学意义（P ＜0．05）；碱清洗组和多酶清洗组比较差异有统计学意义（P ＜0．05）。结论在机洗＋酶清洗前，使用碱清洗剂进行器械的预处理可以有效地去除蛋白质、油脂类等污染物，使妇科器械的清洗效果更好。
