摘要
目的观察医院物体表面采用清洁与消毒方法后，物体表面细菌总数变化，为医院减少消毒剂使用提供依据。方法选择医院Ⅲ类环境物体表面如普通病房、治疗室等，随机分成试验组和对照组，试验组用自来水擦拭地面、桌椅及墙面。对照组常规采用含500mg／L有效氯消毒液擦拭消毒。监测清洁消毒前、清洁消毒后0．5，1．0，2．0，4．0h 2组地面、桌面、墙面细菌菌落总数变化。结果2组清洁消毒前及清洁消毒后不同时间段物体表面细菌培养合格率比较差异无统计学意义（P〉0．05）。结论除非有血液或体液污染，医院Ⅲ类环境物体表面，一般可用自来水作清洁处理而无需每日常规使用消毒液进行消毒处理。
Objective To observe the changes of number of bacterium on the surface of objects in hospital by cleanness and disinfection method, and then make out logical cleanness method for hospital. Methods Selected different surface of objects in Ⅲ hospital environment, and then sterilized by cleanness and disinfection method. Compared the changes of number of bacterium at the appointed time points between the two methods, Results There was no significant difference between the two methods in the changes of number of bacterium which we have monitored,P〉0.05. Condusions Cleanness method was enough unless there were blood or body fluid on the surface of objects in Ⅲ hospital environment.
