发热门诊过氧化氢空气消毒效果研究

目的观察过氧化氢消毒剂气溶胶喷雾和普通喷壶喷雾对医院发热门诊空气细菌杀灭效果。方法对发热门诊空气中菌落数进行消毒前和消毒后监测。结果3％过氧化氢用普通喷壶喷雾后60min，平均细菌杀灭率仅为3．04％；气溶胶喷雾器喷雾后60min，平均细菌杀灭率为87．31％，差异显著。结论过氧化氢消毒剂气溶胶喷雾作用30～60min即可达到可靠的消毒效果；此方法省时、省力、方便、易行；杀菌效果明显高于普通喷壶喷雾，且节约药物。

Air Sterilization of Hydrogen Peroxide Solution in Department for Fever Outpatients:An Efficacy Study

OBJECTIVE To compare the effect of hydrogen peroxide during air sterilization in the Department for Fever Outpatient in our hospital by aerosol sprayer with general sprayer. METHODS To monitor the colony forming unit (CFU) in our Department before and after sterilization. RESULTS The average sterilization ratio, when we used 3% hydrogen peroxide in an aerosol sprayer, was 87.31%. However, when in a general sprayer, the ratio decreased to 3.04%. Apparently, there was a significant margin between them. CONCLUSIONS We can get credible sterilization effect 30 to 60 minutes after spraying hydrogen peroxide as a disinfectant. Furthermore, it is a more convenient, time-saving, less consuming way. Its sterilization effect is more effective than general sprayer.
