改进氧气湿化瓶消毒方法的临床效果观察黄晓岭郑玉婷方伟张晓香(哈尔滨医科大学第四临床医院感染监控科黑龙江哈尔滨 150001 ) 摘要: 目的观察改进的氧气湿化瓶消毒方法和持续使用时间的临床效果。方法分两阶段进行消毒监测。第一阶段分 2组, 观察组使用无菌蒸馏水为湿化液, 并使用改进的消毒措施, 对照组使用冷开水为湿化液, 并采用传统消毒方法。对两组第 3 天的监测结果进行对比分析和统计学处理。第二阶段对 50 份持续吸氧的湿化液每天做细菌监测,对 1~7 天的结果进行对比分析。结果第一阶段观察组湿化瓶持续使用 3 天后的湿化液细菌监测合格率较对照组高, 有显著性差异(P<) ; 第二阶段持续吸氧后湿化液第 7 天与第 1 天的细菌数比较有显著性差异(P<) 。结论改进吸氧装置的消毒方法,定时更换消毒湿化瓶,能有效减少吸氧患者感染的机会。氧气湿化瓶持续使用的第 7 天必须更换消毒,以有效控制细菌生长,控制院内感染发生。关键词:氧气湿化瓶;细菌监测;湿化液;消毒方法;效果观察 Clinic observation of improvement to the disinfection method for oxygen moisture bottle 【 Abstract 】 Objective To study the best and most effective method for disinfection of oxygen moisture bottles. Methods In the first stage : one hundred and nine oxygen moisture bottles were divided into control and treated groups. The bottles in both groups were immersed in % dosomfectpr for 30minutes , then the bottles in control group were rinsed with sterile distilled water and dried for use ; the treated group dried with 95% alcohol for use. Samples in both groups were taken on the third days of disinfection. A nd the moisture fluid used in treated group was sterile distilled water while of the control group was cool oil water. In the second stage, the contamination rate were tested from 1 st day to7 th day in treated group. Results The contamination rate increased with the length of preservation time , the treated group was lower than the c
