目的比较空气净化器与紫外线灯对急诊科换药室空气消毒的临床效果。方法分别应用空气净化与紫外线2种方法对急诊科换药室进行空气消毒,计算消毒前后菌数,比较消毒效果。结果 2种消毒方法均对急诊科换药室的空气消毒有效,但空气净化消毒后菌数的减少值明显高于紫外线组。结论急诊科换药室应用空气净化消毒法,效果更好,能更有效地清除病原体,可以在临床中推广应用。 Objective To compare the clinical effects of air purifiers and UV lamps on air disinfection of emergency department changing rooms. Methods Two kinds of methods of air purification and UV were used respectively to disinfect air in the emergency room, and the number of bacteria before and after disinfection was calculated, and the disinfection effect was compared. Results Both disinfection methods were effective for air disinfection of emergency department changing room, but the reduction of bacteria in air disinfection was significantly higher than that of ultraviolet group. Conclusions The emergency department’s dressing room should be cleaned and disinfected by air. The effect is better and the pathogens can be removed more effectively. Therefore, it can be widely applied in clinical practice.
