目的比较抹布集中高温清洗后浸泡250 mg/L含氯消毒剂、消毒湿巾、抹布手洗三种方法的清洁消毒效果。方法采用随机对照试验,在新生儿重症监护病房(NICU)对上述3种清洁消毒方法的效果进行对比研究。结果清洁消毒前,3组物体表面的细菌菌落数无显著差异(F=0.96,P>0.05);清洁消毒后30 min、2 h、6 h,3组物体表面菌落数比较有统计学差异(F=10.59,P<0.05),其中高温清洗消毒组与消毒湿巾组比较无差异,但两组菌落数明显少于抹布手洗组。前两种方法在消毒前后的菌落数均有显著差异;而抹布手洗组消毒前后不同时点的菌落数比较无统计学差异(F=2.25,P>0.05)。结论综合3种方法消毒效果,建议普通病区使用抹布集中高温清洗消毒方法,重点病区及ICU使用消毒湿巾进行物体表面清洁。
Objective To compare the cleaning and disinfection effects of the three methods of soaking 250mg / L chlorine-containing disinfectant, disinfecting wet wipes, and hand-washing cloth after high temperature cleaning. Methods A randomized controlled trial was conducted to compare the effects of the above three cleaning and disinfection methods in neonatal intensive care unit (NICU). Results Before cleaning and disinfection, there was no significant difference in the number of bacterial colonies on the three groups (F = 0.96, P> 0.05). After 30 min, 2 h and 6 h after disinfection, F = 10.59, P <0.05). There was no difference between the high-temperature cleaning and disinfecting groups and the disinfecting wet-wipe group, but the number of colonies in the two groups was significantly less than that of the handwashing group. The first two methods before and after disinfection of the number of colonies were significantly different; and handwashing group before and after disinfection at different time points no significant difference in the number of colonies (F = 2.25, P> 0.05). Conclusion Based on the disinfection effects of the three methods, it is suggested that the common ward should be cleaned and disinfected by using concentrated rag cloth. The key wards and the ICU should be disinfected wipes to clean the objects.
