目的评价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烧伤科病房空气的消毒效果,为选择理想的烧伤科病房空气消毒方法提供依据。方法分别用两种方法对病房空气进行消毒,采样监测并对结果进行比较分析。结果两种方法对病房空气消毒后杀灭率分别为60.1%和92.0%,消毒合格率分别为60.4%和95.8%,两种方法消毒后合格率差异有显著性(P<0.01)。结论烧伤科病房两种消毒方法中,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、有效的病房空气消毒方法。
Objective To evaluate the disinfection effect of two kinds of disinfection methods, including ultraviolet radiation and compound chlorine disinfectant aerosol spray, on the air of burn unit ward, to provide basis for choosing the ideal method of air disinfection of burn unit ward. Methods Two methods were used to disinfect the ward air, sampling and monitoring, and the results were compared and analyzed. Results The disinfection rates of the two methods after air disinfection were 60.1% and 92.0%, respectively. The disinfection pass rates were 60.4% and 95.8%, respectively. There were significant differences in pass rates between the two methods after disinfection (P <0.01). Conclusion Among the two disinfection methods in burn unit wards, the disinfection effect of compound chlorinated disinfectant is better than ultraviolet radiation group, which is a simple, rapid, safe and effective ward air disinfection method.
