氧气湿化瓶消毒方法的探讨

The Exploration of sterilization Methods of Oxygen Humidifier

１９９４年２月～１９９５年１０月，作者对医院临床内科氧气湿化瓶污染情况进行了调查。结果提示：湿化瓶的液体中存在大量的细菌生长，检出率为７８．９％，以革兰氏阴性菌为主。选用三种消毒液浸泡湿化瓶消毒，（０．２％过氧乙酸，１：１００＂８４＂消毒液与０．１％的新洁尔灭）消毒效果相比较，Ｐ＜０．０１具有显著性。消毒后病人使用湿化瓶和干燥备用湿化瓶分别于第４天和第７天有细菌生长。消毒后湿化瓶，病人使用应每周消毒２次，干燥备用湿化瓶超过１周应重新消毒。

The author conducted an investigation about the contaminated situation of oxygen humidifier of the hospital internal ward from Feb.1994 to Oct.1995. The result indicated:There were a great deal of bacteria growing in the humidifer liquid. The detectable rate was 78.9%,and they were mainly G-bacteria. Three kinds of sterilized liquids were selected to soak humidifier for sterilization(0.2% peracetic acid, 1: 100'84' sterilization liquid, 0.1% bromogeramine).The result was obviously different(P<0. 01). The patients used sterilized humidifier and dry-prepared humidifier, bacteria grew in the fourth day and seventh day respectively. So sterilized humidifier must sterilize two times every week and dry-prepared humidifier must sterilize once a week after patients used.
