目的研究紫外线照射和复方含氯消毒液气溶胶喷雾两种消毒方法对传染科病房环境空气的消毒效果。方法对传染科病房进行随机分组,用2种方法对病房环境空气消毒后,空气微生物采样及细菌培养,并进行数据分析。结果 2种方法对传染科病房环境空气消毒后灭菌率分别为61.5%和93.3%,差异有显著性(P<0.01);消毒合格率分别为62.9%和97.1%,差异有显著性(P<0.01)。结论传染科病房2种消毒方法中,复方含氯消毒液消毒效果优于紫外线照射组,是一种简便快速安全有效的病房环境空气消毒方法。
Objective To study the disinfection effect of two kinds of disinfection methods, including ultraviolet irradiation and compound chlorine disinfectant aerosol spray, on the ambient air in infectious wards. Methods Infectious diseases wards were randomly divided into two groups. After two kinds of methods were used to disinfect the wards’ ambient air, the samples of airborne microorganisms and bacterial culture were analyzed and the data were analyzed. Results The disinfection rates of the two methods were 61.5% and 93.3% respectively after disinfecting the ambient air in infectious wards, with a significant difference (P <0.01). The disinfection pass rates were 62.9% and 97.1% respectively, with significant difference (P <0.01). Conclusion In the two disinfection methods of infectious ward, the disinfection effect of compound chlorine disinfectant is better than that of ultraviolet radiation group, which is a simple, quick and safe ward environment air disinfection method.
