不同材质抹布对医疗机构环境物体表面清洁消毒效果的影响

Effect of different material wipes on disinfection efficacy of environmental object surface in medical institutions

目的探索不同材质的抹布对环境物体表面清洁和消毒的效果。方法对同一物体表面的清洁和消毒设置对照组与实验组(4个组别),实验1组采用超细纤维抹布+清洁剂进行擦拭,实验2组采用普通棉质抹布+清洁剂进行擦拭,实验3组采用超细纤维抹布+消毒剂进行擦拭,实验4组采用普通棉质抹布+消毒剂进行擦拭;设置对照组和实验组(A、B组),实验A组采取含2 000 mg/L双链季铵盐消毒剂的一次性消毒湿巾进行擦拭,实验B组采用超细纤维抹布+清洁剂进行擦拭,对照组均不采取任何擦拭措施,每组标本50份,计算各组细菌菌落总数、合格率、平均清除率等。结果共采集400份标本。实验1组、实验2组合格率分别为90.00%和66.00%;实验3组、实验4组合格率分别为98.00%和92.00%;超细纤维抹布联合使用清洁剂、消毒剂对物体表面擦拭后合格率均高于普通棉质抹布,差异均有统计学意义(均P<0.05)。超细纤维抹布联合使用清洁剂与消毒剂后,对细菌的清除率分别为91.99%和94.00%;普通棉质抹布联合使用清洁剂与消毒剂后,对细菌的清除率分别为64.07%和90.00%;使用超细纤维抹布联合清洁剂、一次性消毒湿巾对医院环境物体表面进行擦拭后,平均清除率分别为91.00%和92.01%。结论超细纤维材质有更好的消毒和清洁效果,该材质的应用可减少消毒剂的使用,不仅利于环境保护,还可减少临床工作量。

Objective To explore the cleaning and disinfection effect of wipes with different material on the surface of environmental object.Methods Cleaning and disinfection of the same object surface were set up control group and experimental group(4 groups),experimental group1 was wiped with ultrafine fiber cloth+detergent,experimental group 2 with common cotton cloth+detergent,experimental group 3 with ultrafine fiber cloth+disinfectant,and experimental group4 with common cotton cloth+disinfectant;another control group and experimental group(group A and B)were also set up,group A was wiped with disposable disinfection wet wipes containing2 000 mg/L doublechain quaternary ammonium salt disinfectant,group B was wiped with ultrafine fiber cloth+detergent,control group didn’t take any wiping measures,50 specimens were collected from each group,the total number of bacterial colonies,qualified rate,and average clearance rate of bacteria of each group were calculated.Results A total of 400 specimens were taken.The qualified rates of experimental group 1,2,3,and 4 were 90.00%,66.00%,98.00%,and 92.00%respectively;the qualified rates of ultrafine fibre cloth+detergent and ultrafine fibre cloth+disinfectant were both higher than that of common cotton cloth,difference were both statistically significant(both P<0.05).Bacterial clearance rates of ultrafine fibre cloth combined with detergent and disinfectant were 91.99%and94.00%respectively;bacterial clearance rates of common cotton cloth combined with detergent and disinfectant were 64.07%and 90.00%respectively.After wiping the surface of hospital environmental objects with superfine fibre cloth combined with detergent and disposable disinfection wet wipes,the average clearance rates were 91.00%and 92.01%respectively.Conclusion Ultrafine fiber material has better disinfection and cleaning effect,application of this material can reduce the use of disinfectant,not only conducive to environmental protection,but also reduce clinical workload.
