气雾熏蒸法与浸泡消毒法消毒吸痰管效果比较

目的比较2%强化戊二醛(下称戊二醛)气雾熏蒸法与浸泡消毒法消毒吸痰管的效果.方法消毒按5周期(1个周期12 d)进行,每周期将200根使用过的吸痰管经初步处理,即5% 84消毒液浸泡30 min后清水冲洗干净晾干.将每周期200根吸氮管随机均分为实验组和对照组,实验组采用戊二醛原液气雾熏蒸法消毒4 h,对照组采用戊二醛原液浸泡消毒30 min,12 d为1个周期.两组分别于第1、6、12天对消毒后的吸痰管及消毒过程中的戊二醛采样行细菌菌落数计数,并观察有无细菌生长.结果两组每周期第1、6天吸痰管和消毒液标本均未检测出细菌,且无致病微生物生长;每周期第12天对照组吸痰管和消毒液标本均检测出细菌,实验组未检测出细菌.结论气雾熏蒸法消毒灭菌效果可靠,具有节约开支、使用方便、有利于吸痰管的保存与放置等优点.

Effectiveness of Sterilized Absorbing-sputum Tube by Fog-fumigating and Dipping Sterilization

Objective To study the effectiveness of sterilized absorbing-sputum tube by fog-fumigating and dipping sterilization.Methods During a period of 12 days, the used absorbing sputum tubes were randomly into 2 groups after basic disposal (dipping in 5% 84 sterilizing liquid for 30 min and then washing). The tubes in the tested group were sterilized by fog-fumigating for 4 h and those in the control group by dipping sterilization for 30 min. The samples of absorbing-sputum tubes and the fluid during sterilization were obtained at the first day, 6th day and 12th day separately, numbering bacteria were observed.Results On the first and 6th day during each period, bacteria were not detected in the samples of absorbing-sputum tubes and sterilized liquid. On the 12th day in each period, bacteria were detectable in the control group, but not detectable in the tested group. Conclusion Fog-fumigating for sterilization of absorbing-sputum tubes is economic, convenient, and is easy to deposit and save in comparing to dipping sterilization.
