两种方法消毒呼吸机外部管道的效果评价

Effective Evalution of Two Different Ways on Disinfecting the Ventilator＇s Pipes

目的探讨两种消毒方法用于消毒呼吸机外部管道的消毒效果．以选择最佳的呼吸机外部管道的消毒方法。方法回收临床各科室连续使用3天的呼吸机外部管道，随机分为两组：采用全效酶清洗液漫泡＋含氯消毒液浸泡消毒灭菌（A组），全效酶清洗液浸泡＋环氧乙烷消毒灭菌（B组）。两组分别于消毒前、消毒后、放置7天采样进行细菌培养及细菌落计数，比较两组各时段的细菌杀灭率。结果两种方法均能达到高水平消毒，环氧乙烷消毒灭菌法灭菌效果最佳。

Objective To explore the disinfection effect of using two different ways on ventilator＇s pipes, in order to choose the best way of disinfection. Methods Recycling clinical departments＂ ventilators＂ pipes consecutively used for three days were randomly divided in two groups： using the entire enzyme clean and immerse ＋ chlorine disinfect and sterilize （group A）, using the entire enzyme clean and immerse ＋ ethylene oxide disinfect and sterilize （grope B）.Samples from the ventitator＇s pipes were cultured before, after and seven days later＇s disinfection, the number of bacterium colony forming uint were counted. Compare with two groups of various stages bacterium elimination rate. Result the two methods of disinfection are all effective, but the ethylene oxide is the best.
