氧气湿化瓶消毒方法的探讨

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 Exploration of sterilization Methods of Oxygen Humidifier

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.
