目前 ,我国环境空气要求普通手术间中的细菌菌落总数在≤ 2 0 0 cfu/m3。近年来 ,我院手术室所做的空气监测培养 ,测定结果均符合上述标准 ,现就目前消毒空气常用方法并结合我院对手术室的工作实践介绍如下。1　紫外线照射1.1　杀菌机理 :波长范围 2 0 0～ 2 75 nm杀菌作用最强 At present, the ambient air in our country requires that the total number of bacterial colonies in common operating rooms be ≤200 cfu / m3. In recent years, our hospital operating room air monitoring and training, the measured results are in line with the above criteria, are now commonly used methods of disinfection air combined with our hospital on the operating room work practices are as follows. 1 UV irradiation 1.1 bactericidal mechanism: the wavelength range of 200 ~ 2 75 nm bactericidal effect strongest
