Comparison of the Effect of Multifunctional Air Disinfection Machine and Ultraviolet Disinfection on Air Purification and Disinfection in Emergency Rescue Room
摘要
Abstract
Objective To analyze and compare the effect of multifunctional air disinfection machine and ultraviolet disinfection on air purification and disinfection in emergency rescue room,and to provide relevant reference for reducing nosocomial infection in emergency rescue room.Methods A total of 60 cases of fever diagnosis patients in the emergency rescue room of our hospital from January to December 2022 were selected as the study objects.According to different disinfection methods,they were respectively assigned to the multifunctional air disinfection group(n=30)and the ultraviolet disinfection group(n=30).The concentrations of particulate matter[PM0.3(particulate matter with diameter≤0.3 μm in the air,and so on),PM0.5,PM1.0,PM3.0,PM5.0]in the air of the two groups were detected,and the air purification effect of the two groups was observed(the total number of bacterial colonies in the air 0,15,20 min after the patient entered the room).Results Before disinfection,there was no significant difference in PM0.3-1.0,PM1.0-3.0,PM1.0-5.0 and PM3.0-5.0 concentrations between the two groups(P>0.05).After disinfection,the PM0.3-1.0,PM1.0-3.0,PM1.0-5.0 and PM3.0-5.0 particulate concentrations of the multifunctional air disinfection group were lower than those of the ultraviolet disinfection group,the difference were statistically significant(P<0.05).Intra-group comparison showed that there were no significant differences in PM0.3-1.0,PM1.0-3.0,PM1.0-5.0 and PM3.0-5.0 particulate concentrations in the ultraviolet disinfection group before and after disinfection(P>0.05).The particulate concentrations of PM0.3-1.0,PM1.0-3.0,PM1.0-5.0 and PM3.0-5.0 after disinfection of multifunctional air disinfection group were lower than those before disinfection,and the differences were statistically significant(P<0.05).Comparison of total bacterial colonies:15 and 20 min after disinfection,the total bacterial colonies of multifunctional air disinfection group were significantly lower than those of ultraviolet disinfection group,the difference was statistically significant(P<0.05).Comparison of disinfection rate:15 and 20 min after patients entered the room,the disinfection rate of multifunctional air disinfection group was significantly higher than that of ultraviolet disinfection group,the difference was statistically significant(P<0.05).Conclusion The air purification and air disinfection effect of multifunctional air disinfection machine in emergency rescue room is better than that of ultraviolet disinfection,which is suitable for clinical application.关键词
