氧气湿化瓶清洗消毒过程的细节优化

Optimization in Details of Cleaning and Disinfection Process of Oxygen Humidification Bottles

目的为探索提高重复使用氧气湿化瓶的清洗消毒质量,通过实验比较两种不同浸泡方法以及终末漂洗选择常水与纯水对重复使用氧气湿化瓶清洗消毒效果的影响,寻求最佳清洗消毒流程。方法采用无菌棉拭子涂擦采样和细菌定量检测方法,第1组实验中实验组采用多酶清洗液浸泡后再用84消毒液浸泡消毒,对照组只使用多酶清洗液浸泡。第2组实验中实验组消毒后选择纯水冲洗,对照组选择自来水。对清洗后的每个氧气湿化瓶进行采样,样本送微生物实验室进行细菌培养和菌落计数。结果经多酶清洗液和84消毒液浸泡后的氧气湿化瓶消毒合格率100%,仅经多酶清洗液浸泡的氧气湿化瓶合格率为92%。消毒后使用纯水冲洗的合格率为100%,使用自来水冲洗的合格率为72%。结论由消毒供应中心集中清洗的氧气湿化瓶,其清洗质量能得到保证;氧气湿化瓶在急救时可不经84消毒液消毒;使用纯水终末漂洗其清洗效果明显优于使用自来水。

Objective To explore a better cleaning and disinfection process to improve the quality of cleaning and disinfection of reusable oxygen humidification bottles. Methods The sterile cotton swab sampling method and quantitative detection of bacteria（ bacterial culture and colony count） were used to compare the different disinfection effect of methods whether using 84 Disinfectant or not after soaking in muhi-enzyme cleaner and rinsing with tap water or with distilled water. Results The qualified rate of the disinfected oxygen humidification bottles that were soaked in 84 Disinfectant after soaking in multi-enzyme cleaner was 100% ,while the bottles only soaked in multi-enzyme cleaner was 92%. The qualified rate of disinfected oxygen humidification bottles that were rinsed with tap water was only 72% ,while with distilled water was 100%. Conclusion The concentrated clean- ing and disinfection process by CSSD can ensure a better quality as compared to the dispersed sterilization in different department. Soaking the oxygen humidity bottles after being soaked in multi-enzyme cleaner is just one option. To use the distilled water rather than tap water should make the rinsing works better.
