4种氧气湿化瓶和通气管干燥方法的效果比较

Effect Comparison of Four Kinds of Drying Methods for Oxygen Humidification Bottle and Airpipe

目的使各临床科室的备用氧气湿化瓶及通气管在有效期内细菌学检查合格率达到100%,符合《消毒技术规范》和《医院消毒卫生标准》的要求,预防患者院内呼吸道感染。方法在不同的时间段采用4种不同的干燥方法:干燥箱烘干法、无菌纱布擦干法和高压气枪吹干法、高压蒸汽灭菌锅余热干燥法,分别对500个氧气湿化瓶、通气管进行处理,观察其成本、时间、优缺点,并通过细菌学检验4种方法的处理效果。结果在4种干燥方法中,高压蒸汽灭菌锅余热干燥法价格低廉,取材方便,干燥彻底,保障了消毒氧气湿化瓶及通气管的消毒效果,经比较,细菌值少于其它3种干燥法(p<0.05);经细菌学检查,经处理的备用氧气湿化瓶及通气管在有效期内的细菌值均为0,合格率为100%。结论由于改进了消毒氧气湿化瓶及通气管的干燥方法,使氧气湿化瓶干燥彻底,避免了消毒后氧气湿化瓶及通气管的再次污染,同时降低了护理人员的劳动强度,缩短了氧气湿化瓶的干燥时间,提高了工作效率。

Objective： To make sure the bacteriology examination of oxygen humidification bottle and airpipe qualification rate to 100% in every department, to prevent the respiratory infection of patients. Methods： Adopt four kinds of drying methods in different time, that is baking oven airing, sterile gauze drying, high pressure air syringe and high pressure steam sterilization methods. Compare their effect. Results： High pressure steam sterilization methods were cheaper, convenient, the qualification rate was 100%, bacteria number was less than the other three methods （p 〈0.05）. Conclusion： The improved drying methods make drying more completely, decrease the drying time of oxygen humidification bottles and improved the work efficiency.
