【摘要】：目的观察不同消毒方法对医院手术室计算机键盘及鼠标消毒前后的消毒效果。方法使用500 mg/L含氯消毒液和含双长链季铵盐清洁消毒湿巾对医院手术区域公共计算机键盘和鼠标进行物体表面清洁消毒,分别用传统细菌培养法和ATP荧光检测法对消毒前后的细菌数与相对发光单位值(RLU)进行测定。结果消毒前不同区域的键盘和鼠标细菌数为0~56 cfu/件,含氯消毒剂和双长链季铵盐清洁消毒湿巾清洁消毒后键盘和鼠标细菌数为0 cfu/件。消毒前不同区域的键盘和鼠标ATP荧光检测为6~354 RLU/件,含氯消毒剂清洁消毒30 min后ATP荧光检测为0~12RLU/件,双长链季铵盐清洁消毒湿巾清洁消毒后键盘和鼠标ATP荧光检测均为0RLU/件。两种清洁消毒方法检测计算机键盘和鼠标表面消毒前后菌数无统计学差异,但是消毒后30 min ATP值差异均有统计学意义(P0.01)。结论办公室内使用的电脑键盘、鼠标表面存在不同程度污染,采用双长链季铵盐清洁湿巾对电脑键盘和鼠标去污功效更明显。
[Abstract]:Objective to observe the disinfection effect of different disinfection methods on computer keyboard and mouse in hospital operating room before and after disinfection. Methods using 500 mg/L chlorinated disinfectant solution and double long chain quaternary ammonium salt cleaning disinfectant wet towel to calculate public operation area of hospital. The machine keyboard and mouse are used to clean and disinfect the surface of the object. The bacterial number and relative luminescence unit value of bacteria before and after disinfection were determined by traditional bacterial culture method and ATP fluorescence detection method respectively. Results the bacterial numbers of keyboard and mouse in different areas before disinfection were 0 ~ 56 cfu/, respectively. Chlorine disinfectant and double long chain quaternary ammonium salt were used to clean and disinfect wet napkins. The bacterial number of keyboard and mouse was 0 cfu/ after disinfection. The fluorescence detection of ATP of keyboard and mouse in different areas before disinfection was 6 RLU/. After 30 min of cleaning and disinfection with chlorine disinfectant, the fluorescence detection of ATP was 0 ~ 12 RLU / piece. Double long chain quaternary ammonium salt cleaning and disinfecting wipes after cleaning and disinfecting, the fluorescence detection of keyboard and mouse ATP were both 0RLU / piece. There was no statistical difference between the two cleaning and disinfection methods before and after disinfection of computer keyboard and mouse surface. However, there were significant differences in ATP values at 30 min after disinfection (P 0.01). Conclusion the computer keyboard and mouse surface used in the office are polluted to varying degrees, and the effect of cleaning wet towel with double chain quaternary ammonium salt on computer keyboard and mouse is more obvious.
