不同方法对消毒供应中心器械包装台的消毒效果

Disinfection effect of different methods on the instrument packaging table of the disinfection supply center

目的比较不同清洁消毒方法对消毒供应中心器械包装台消毒效果。方法采用一次性季铵盐长效消毒湿巾、含氯消毒剂、纯化水擦拭消毒器械包装台面待干,分别用微生物法和三磷酸腺苷(ATP)生物荧光法对消毒后5 min、2 h、4 h、6 h、8 h的消毒效果进行检测,比较3种方法的消毒效果、用时及成本。结果季铵盐消毒湿巾、含氯消毒剂、纯化水擦拭8 h内细菌菌落数均≤10 CFU/cm^(2);季铵盐消毒湿巾擦拭8 h内细菌菌落数与含氯消毒剂比较,差异无统计学意义;季铵盐消毒湿巾、含氯消毒剂擦拭8 h内ATP值均≤200 RLU,纯化水擦拭6 h内ATP值均≤200 RLU;季铵盐消毒湿巾擦拭4 h、6 h ATP值低于含氯消毒剂(P<0.05)。季铵盐消毒湿巾用时最少,费用最低。结论季铵盐消毒湿巾、含氯消毒剂、纯化水均可用于Ⅲ类环境物表常规清洁消毒,季铵盐消毒湿巾使用便捷,消毒效果可靠,节约时间及成本。

OBJECTIVE To compare the disinfection effects of different cleaning and disinfection methods on instrument packaging tables in disinfection supply center.METHODS Disposable quaternary ammonium salt long-lasting disinfection wipes,chlorine-containing disinfectants,purified water wipes disinfection instrument packaging table surface to be dried,microbial method and adenosine-triphosphate(ATP)biofluorescence method were used to detect the disinfection effect of 5 min,2 h,4 h,6 h and 8 h after disinfection,and the disinfection effect,time and cost of the three methods were compared.RESULTS Quaternary ammonium disinfection wipes,chlorine-containing disinfectant and purified water wipes were≤10 CFU/cm^(2)within 8 h.Quaternary ammonium disinfection wipes wiping the number of bacterial colonies compared with chlorine disinfectants,the difference was not statistically significant;Quaternary ammonium disinfection wipes and chlorine-containing disinfectant wipes have an average ATP value of≤200 RLU within 8 h,and the average ATP value within 6 h of purified water wipes≤200 RLU.However,quaternary ammonium disinfectant wipes wiped 4 h,6 h ATP value is lower than chlorine-containing disinfectant(P<0.05).Quaternary ammonium disinfectant wipes take the least time and cost the lowest.CONCLUSION Quaternary ammonium disinfection wipes,chlorine-containing disinfectants and purified water can be used for routine cleaning and disinfection of class iii environmental surfaces,and quaternary ammonium disinfection wipes are convenient to use,the disinfection effect is reliable,and the time and cost are saved.
