两种消毒方法用于重症监护室医疗仪器表面清洁消毒的效果比较

Comparison of two disinfection methods used in the surface cleaning and disinfection of medical instrument in intensive care unit

目的比较卫生湿巾和医用酒精+纱布两种方式对重症监护室医疗仪器表明清洁消毒的效果。方法对ICU医疗仪器表面分别采用卫生湿巾和医用酒精+纱布进行清洁消毒,使用生物荧光(ATP)检测仪检测两种方法清洁消毒前后仪器设备表面的污染程度,使用满意度调查问卷测评医务人员对使用两种方法的主观感受。比较两种消毒方法的成本。结果卫生湿巾组清洁消毒后仪器表面的相对发光光度(RLU)降低量和降低率与医用酒精+纱布组比较,差异均有统计学意义(P<0.05);卫生湿巾在使用的方便性、清洁消毒所需时间这两方面的满意度优于医用酒精+纱布;使用成本也低于医用酒精+纱布,差异有统计学意义(P<0.05)。结论卫生湿巾对医疗仪器表面清洁消毒效果和医务人员满意度方面优于医用酒精+纱布,是一种适宜于临床作为仪器设备表面清洁消毒的新方式。

Objective To compare the disinfection effect of hygiene wipes and gauze with medicinal alcohol used for medical instruments in ICU. Methods The bioluminescence （ATP） detector was used to detect the equipment surface pollution degree （ rela- tive luminosity, RLU） of two kinds of decontamination methods. The subjective feelings of medical staff were evaluated by a satisfaction questionnaire. The costs of the two disinfection methods w^re compared. Results RLU reduction rate of medical instrument in the hy- giene wipes group was higher than that in the group of gauze with medicinal alcohol （P 〈 0. 05）. The satisfaction survey showed that hygiene wipes were better than gauze with medicinal alcohol in term of easy to use and time of cleaning （P 〈 0. 05）. The costs of hy- giene wipes were lower than gauze with medicinal alcohol. Conclusion The hygiene wipes were better than traditional gauze with medicinal alcohol in disinfection effect and medical staff satisfaction. It is a new way to clean and disinfect the surface of instrument and equipment.
