过氧化氢与过氧乙酸气溶胶喷雾空气消毒临床观察

目的了解过氧化氢与过氧乙酸消毒剂气溶胶喷雾用于临床空气消毒的效果及对人体的危害性。方法将新建病区98间普通病房随机分为两组,采用过氧乙酸气溶胶喷雾为对照组,对两种的空气消毒效果及对人体的危害性进行临床观察。结果两种气溶胶喷雾消毒后30min进行平板暴露法采样,细菌菌落总数均达到Ⅲ类环境合格标准,无致病菌检出;过氧化氢对人体无明显黏膜刺激和过敏反应,过氧乙酸对人体均有黏膜刺激和过敏反应。结论气溶胶喷雾在新建病区、改扩建病区或出现特殊感染病例时,在室内无人情况下,仍是一种空气消毒的有效方法;目前,某些不良反应强、污染环境的化学消毒方法,如过氧乙酸,因其对人体的刺激性、毒性和对物品的腐蚀性而限制了应用;而通风、除尘、净化、紫外线照射、在有人状态下可以开机使用的动态空气消毒机等方法已成为空气消毒新的理念。

Air Disinfection Using Aerosol Sprayer of Hydrogen Peroxide and Pel-acetic Acid: Its Clinic Observation

OBJECTIVE To find out the clinic air disinfectant effect and the damage to human body between air aerosol sprayer of hydrogen peroxide and peracetic acid. METHODS New ninety eight sickrooms were randomly disported into two groups. The group of using peracetic acid was a control one. Then the clinic air disinfectant effect and the damage between two groups were observed. RESULTS After thirty minutes, to sample through flat exposure method. The total number of bacteria of two groups reached the third grade of environment eligible standard without pathogenic bacteria being checked. Hydrogen peroxide had not obvious mucous membrane stimulation and hypersusceptible reaction to human body. But peracetic acid had mucous membrane stimulation and hypersusceptible reaction to human body. CONCLUSIONS The air disinfection using aerosol sprayer is still an available method when there are no person in new sickrooms or extended sickrooms. At present, some chemical disinfectant methods that have strong poisonous reactions and pollute environment, such as peracetic acid, have been restricted to be used because of thrill, toxicity to human body and causticity to goods. But the method of dynamic air disinfectant machine that can be used in the situation of ventilation, dust catching, decontaminating, and ultraviolet irradiation, at the same time having someone has became a new idea of air disinfection.
