为了比较紫外线照射法、过氧乙酸气溶胶喷雾法、静电消毒器法对手术室空气消毒效果,采用对手术室消毒前后空气采样检测方法,观察3种方法对空气中自然菌的杀灭效果。结果,3种消毒方法分别单独作用30min,对手术室空气中自然菌消除率均可达到98％以上;3种方法在作用停止后维持消毒水平均不超过60min,只有静电消毒法可以作为人在条件下持续消毒,但60min后亦不能维持原消毒效果水平;采用两两联合使用,以静电消毒法与过氧乙酸气溶胶消毒法联合使用效果最好。因此,可采用过氧乙酸气溶胶喷雾消毒后,再用静电消毒法维持对手术室空气进行人在条件下消毒。
In order to compare the ultraviolet disinfection method, the peracetic acid aerosol spray method and the electrostatic sterilizer method to disinfect the air in the operating room, the air sampling method was adopted before and after disinfection in the operating room to observe the killing effect of the three methods on the natural bacteria in the air. Results, the three kinds of disinfection methods were 30min alone, the natural room bacteria in the operating room to eliminate the rate of 98% or more; three kinds of methods to maintain the disinfection level after the stop is no more than 60min, only the electrostatic disinfection method can be used as a human Continuous disinfection, but after 60min also can not maintain the original level of disinfection; using a combination of two or two, using electrostatic disinfection combined with peracetic acid aerosol disinfection best. Therefore, aerosol peracetic acid aerosol spray disinfection, and then use electrostatic disinfection method to maintain the air in the operating room for human disinfection under conditions.
