目的 :采用手提式电动气溶喷雾法 ,分别使用过氧乙酸、84消毒液对病床单位消毒 ,确定消毒效果是否安全、有效。方法 :分别采用 0 .2 %过氧乙酸、1∶ 2 0 0 84消毒液气溶胶喷雾法、紫外线灯照法 3种方法对病床单位消毒 ,检测消毒前后平均细菌数。结果 :3种消毒方法消毒前后细菌数有显著性差异 (P <0 .0 1) ,均有明显消毒效果 ;实验组与对照组的消毒效果经秩和检验 ,无统计学差异 (P =0 .317)。结论 :使用过氧乙酸和 84消毒液的气溶胶喷雾消毒法 ,可取代目前常用的病床单位消毒方法。
OBJECTIVE: To adopt the portable electric aerosol spraying method to disinfect the unit of the bed with peracetic acid and 84 disinfectant separately to determine whether the disinfection effect is safe and effective. Methods: The hospital beds were sterilized by 0.2% peracetic acid, 1: 2 0 0 84 disinfectant aerosol spray and ultraviolet lamp irradiation respectively. The mean bacterial counts before and after disinfection were detected. Results: There were significant differences in the number of bacteria before and after disinfection (P <0. 01) among the three disinfection methods, which showed obvious disinfection effect. The disinfection effects in experimental group and control group were not significantly different (P = 0 .317). Conclusion: The aerosol spray disinfection method using peracetic acid and 84 disinfectant can replace the commonly used method of unit disinfection.
