汽化过氧化氢对生物安全实验室工作台面的消毒效果

分别使用汽化过氧化氢、84消毒液和新洁尔灭对生物安全实验室工作台面进行消毒,并对消毒前后相近位置进行采样,对比分析三种消毒方法对生物安全实验室工作台面的消毒效果。试验结果表明:3%过氧化氢消毒剂对金黄色葡萄球菌、大肠杆菌和白色念珠菌均消毒合格;消毒后,汽化过氧化氢组菌落数低于84消毒液组和新洁尔灭组,且差异具有统计学意义(F=3.868,P=0.033);汽化过氧化氢组平均细菌杀灭率大于84消毒液组和新洁尔灭组,且该差异有统计学意义(F=3.487,P=0.045)。汽化过氧化氢的细菌杀灭效果良好,可以替代84消毒液和新洁尔灭用作生物安全实验室工作台面的消毒。

Disinfection effects of vaporized hydrogen peroxide on worktables at biosafety laboratories

Three disinfectants, vaporized hydrogen peroxide, 84 disinfectant, and bromogeramine, were used to disinfect different worktables at a biosafety laboratory, and samples were taken at similar locations before and after disinfection. The effects of the three disinfectants on the worktables of a biosafety laboratory were compared. The results showed that 3% hydrogen peroxide was able to disinfect Staphylococcus spp., Escherichia coli and Candida albicans. The number of colonies after disinfection with vaporized hydrogen peroxide was lower than that after the use of 84 disinfectant and bromogeramine, and the difference was significant (F=3.868, P=0.033). The average bactericidal rate of vaporized hydrogen peroxide was higher than that of the other two disinfectants, and the difference was statistically significant (F=3.487, P=0.045). The sterilization efficacy of vaporized hydrogen peroxide is sufficient to replace 84 disinfectant and bromogeramine for use as disinfectants for worktables at biosafety laboratories.
