不同方法对医院发热门诊物体表面清洁消毒效果的观察

Observations on the effect of different methods on cleaning and disinfecting the surfaces of objects in a hospital fever clinic

目的探讨不同方法对发热门诊物体表面的清洁消毒效果,为选择合适的物体表面清洁消毒方法提供依据。方法将发热门诊的高频接触物体表面分为对照组和观察组,分别采用含氯消毒液和过氧化氢消毒湿巾进行清洁消毒,采用荧光标记法、三磷酸腺苷生物荧光检测和微生物法对比两组荧光标记的清除率、三磷酸腺苷(adenosine triphosphate,ATP)生物荧光检测合格率和细菌菌落数合格率。运用SPSS 20.0软件,对组间数据采用χ^(2)检验,以P<0.05为差异有统计学意义的差异性分析方法探究清洁消毒效果。结果干预前后发热门诊高频接触物体表面清洁消毒后,含氯消毒液和过氧化氢消毒湿巾对荧光标记的完全清除率分别为80.47%和95.03%,两组差异有统计学意义(χ^(2)=35.95,P<0.001);ATP生物荧光检测的合格率分别为93.33%和97.09%,两组差异无统计学意义(χ^(2)=2.15,P=0.143);细菌菌落数合格率分别为98.65%和98.04%,两组差异无统计学意义(χ^(2)=0.12,P=0.744)。结论含氯消毒液和过氧化氢消毒湿巾均可用于医院高频接触物体表面的清洁消毒。对比显示,过氧化氢湿巾操作简单、方便,对医务人员和设备设施损害小,能提高医务人员的工作效率和操作依从性,是一种理想的清洁消毒方法。

Objective To investigate the efficacy of different methods of cleaning and disinfection on the surfaces of objects in fever clinics,so as to provide a basis for selecting appropriate methods on the surfaces of objects.Methods Frequently touched surfaces of objects in the fever clinical environment were divided into control and observation groups,cleaned and disinfected with chlorine-based disinfectants and hydrogen peroxide disinfectant wipes,respectively.Fluorescence labeling,ATP bioluminescence assay,and microbial processes were used to compare the clearance rates,ATP bioluminescence assay qualified rates,and bacterial colony count qualified rates of the two groups.Utilizing SPSS 20.0 software,the Chi-square test was applied for inter-group data analysis.A statistically significant difference analysis method with P<0.05 was used to explore the effectiveness of cleaning and disinfection.Results Surfaces of high-frequency contact objects in fever clinics before and after intervention,the complete clearance rates for the removal of fluorescent markers using chlorine-based disinfectants and hydrogen peroxide disinfectant wipes were 80.47%and 95.03%respectively,the difference was statistically significant between the two groups(χ^(2)=35.95,P<0.001).The qualified rates for ATP bioluminescence assay were 93.33%and 97.09%respectively,the difference was not statistically significant between the two groups(χ^(2)=2.15,P=0.143).The qualified rates for bacterial colony count were 98.65%and 98.04%respectively,the difference was not statistically significant between the two groups(χ^(2)=0.12,P=0.744).Conclusion Both chlorine-based disinfectants and hydrogen peroxide disinfectant wipes are effective for cleaning and disinfecting surfaces of objects frequently touched in hospitals.Comparative analysis reveals that hydrogen peroxide disinfectant wipes are simple and convenient to operate,causing less damage to medical staff,equipment,and facilities.Moreover,this method enhances work efficiency and operational compliance among medical staff,making it an ideal choice for cleaning and disinfection.
