摘要

目的观察5种常用消毒剂对医疗机构物体表面的消毒效果,探寻适宜的消毒剂和消毒方法。方法 5种消毒剂在5家医疗机构擦拭物体表面消毒后进行,于消毒后0. 25 h、0. 5 h、1 h、2 h、4 h、8 h进行监测,以观察消毒效果及被消毒表面后的细菌消长趋势。结果作用0. 25 h时共采集消毒后样品50份,合格46份,合格率为92. 00%,在消毒后0. 25 h、0. 5 h、2 h、4 h和8 h时,合格率差异均有统计学意义; 5种消毒剂的杀菌率只有在1 h时差异无统计学意义(χ2=6. 68,P> 0. 05)。结论 5种消毒剂杀菌效果各有不同,医疗机构应根据不同需要来选择适宜的消毒剂。当有传染病流行,消毒剂选择更应慎重,以达到满意的消毒效果。
        Objective To observe the disinfection effect on surface of objects in medical institutions by selecting five kinds of commonly used disinfectants,and to explore the most suitable disinfectant and disinfection method for the surface of environmental objects in medical Institutions. Methods We Selected 5 kinds of disinfectants to carry out monitoring in 5 medical institutions. The effect of disinfection was observed at 0. 25 h,0. 5 h,1 h,2 h,4 h and 8 h after disinfection and the trend of bacteria growth and decline on disinfection surface. Results A total of 50 samples were collected after 0. 25 h of disinfection,46 of which were qualified. The qualified rate was 92%. At 0. 25 h,0. 5 h,2 h,4 h and 8 h after disinfection,the differences of qualified rates were statistically significant. There was no significant difference in the disinfection effects of five disinfectants on killing bacteria only at 1 h.( χ2= 6. 68,P > 0. 05). Conclusion Each disinfectant has different germicidal efficacy,and medical institutions should select suitable disinfectants according to different needs. When infectious diseases are prevalent,the selection of disinfectants should be more cautious to achieve satisfactory disinfection effect.
