连台手术室两种空气消毒方法的比较

Effect of Two Air Disinfection Methods in Unremitting Operating Room:Comparison and Evaluation

目的比较三氧消毒机和YKX/G100型医用空气消毒净化机,两种消毒方法对连台手术室空气的消毒效果,探讨连台手术空气消毒方法。方法用自然沉降法于消毒前、后和连台手术开始后的不同时段采样监测,观察两种方法对连台手术室空气中自然菌的杀灭效果。结果两种方法均能使空气中自然菌的杀灭率>85%;三氧机消毒的A手术间,连台手术开始后空气中的菌落数明显上升;空气净化机消毒的B手术间,连台手术开始后空气中的菌落数逐渐下降。结论空气消毒净化机可以缩短手术间隔时间,是解决连台手术有人条件下持续空气消毒的较好方法。

OBJECTIVE To study air disinfection methods in unremitting operating room, we compared effect of using trioxide disinfector （used in operating room ＂ A＂） with YKX/G100-type medical air disinfection and purification machine （used in operating room ＂ B＂） in disinfecting air inside unremitting operating room. METHODS To observe the killing effect on air natural bacteria of the two methods, we used natural sedimentation monitoring the different stages sampling before and after sterilization and at the beginning stage of the unremitting operation. RESULTS Both the two methods could achieve the air natural bacteria eradication rate above 85%. The air bacteria colony number obviously upgraded after the beginning of unremitting operation in operating rooms ＂A＂; but in operating rooms ＂B＂, the number fell-off slowly. CONCLUSIONS The medical air disinfection and purification machine can shorten the interval of operations, it is the better approach of continuous air disinfection in solving the unremitting operating room with personnel existence.
