酸性氧化电位水(AEOW)在复用诊疗物品消毒的应用及分析

Application and Analysis of AEOW in the Reusable Disinfection Medical Instruments

目的探究酸性氧化电位水冲洗浸泡复用诊疗物品临床消毒效果。方法选择2016年3—10月期间该院消毒供应中心回收的呼吸气囊及管路随机编号分成3组,阴性对照组行消毒前采样,试验组1以传统消毒剂消毒,试验组2采用酸性氧化电位水消毒,观察、记录复用诊疗物品采用不同消毒剂相同消毒时间和最佳消毒时间的消毒效果。结果采用传统消毒剂消毒5 min后样本培养菌落数为30~100 cfu/cm^2,酸性氧化电位水样本培养均无细菌生长,同时传统消毒剂消毒30 min后样本培养菌落数为3~18 cfu/cm^2,酸性氧化电位水消毒效果优于传统消毒剂,且达到同样消毒效果所用时间短。结论酸性氧化电位水消毒高效、可靠,能节约消毒成本、减少消毒时间,提高器械的周转效率。

Objective To study the effect of AEOW in the reusable disinfection medical instruments. Methods The rebreathing bag and pipe recycled by the disinfection supply center in our hospital from March 2016 to March 2016 were randomly divided into three groups, the negative control group adopted the sampling before disinfection, the test group 1adopted the traditional disinfectant for disinfection, the test group 2 adopted the electrolyzed oxidizing water for disinfection,and the same disinfection time of different disinfectants and the disinfection effect at the best disinfection time were observed and recorded. Results The sample culture number of colonies was 30~100 cfu/cm^2 after 5 min disinfection, and there was no bacterial growth of the electrolyzed oxidizing water, at the same time, the sample culture number of colonies was 3~18 cfu/cm^2 after 30 min disinfection by the traditional disinfectant, and the disinfection effect of electrolyzed oxidizing water was better than that of the traditional disinfectant, and could reached the same disinfection effect with less time. Conclusion The electrolyzed oxidizing water disinfection is effective and reliable, which can save the disinfection cost, reduce the disinfection time and improve the turnover efficacy of devices.
