摘　　要：目的探讨壁式供氧装置的消毒效果。方法对与患者供氧相关的供氧装置各部位进行消毒前、后细菌培养对照比较。结果湿化瓶消毒前合格率为17.14%,消毒后合格率为100.00%;供氧装置金属螺口消毒前合格率为34.29%、消毒后合格率为94.29%;湿化瓶内的通气管消毒前合格率为8.57%、消毒后合格率为97.14%,消毒前、后合格率比较,差异有统计学意义(P<0.01)。结论挂壁式供氧装置从湿化瓶、湿化瓶内的通气管、湿化液、供氧装置金属螺口、供氧金属管道最后到氧气出口,作为一个整体,应选用合适的方法进行全程消毒,以确保消毒效果。OBJECTIVE To study the sterilization effect of on-wall oxygen humidifying inhalation sets.METHODS The different parts on on-wall oxygen humidifying inhalation sets were sterilized,then compared the result before and after sterilization.RESULTS The regular percents for bacterial examination of humidifying bottle were 17.14% before sterilization,and 100.00% after sterilization,the regular percents for bacterial examination of metallic guilloche were 34.29% before sterilization and 94.29% after sterilization,the regular percents for bacterial examination of vent tube in humidifying bottle were 8.57% before sterilization,and 97.14% after sterilization.The regular percents for bacterial examination of the different parts of oxygen humidifying inhalation sets after sterilization were higher than before it P〈0.005.CONCLUSIONS As the whole of the different parts of oxygen humidifying inhalation sets,we must choose the suitable method to sterilize it in order to assure the sterilization effect.
