摘　　要：目的分析比较多功能空气消毒机与紫外线消毒对急诊抢救室空气净化及消毒效果,为降低急诊抢救室医院感染提供相关参考。方法选取2022年1—12月我院急诊抢救室发热查因患者60例作为研究对象,按照不同的消毒方法使其分别进入多功能空气消毒机组(n=30)和紫外线消毒组(n=30),检测2组空气中的颗粒物[PM_(0.3)(空气中直径≤0.3μm的颗粒物,其他依次类推)、PM_(0.5)、PM_(1.0)、PM_(3.0)、PM_(5.0)]浓度,并观察2组空气净化效果(患者入室后0、15、20 min时空气中的细菌菌落总数)。结果消毒前,2组PM_(0.3-1.0)、PM_(1.0-3.0)、PM_(1.0-5.0)、PM_(3.0-5.0)颗粒物浓度差异无统计学意义(P>0.05);消毒后,多功能空气消毒机组的PM_(0.3-1.0)、PM_(1.0-3.0)、PM_(1.0-5.0)、PM_(3.0-5.0)颗粒物浓度均低于紫外线消毒组,且差异有统计学意义(P<0.05)。组内比较发现:紫外线消毒组消毒前、后PM_(0.3-1.0)、PM_(1.0-3.0)、PM_(1.0-5.0)、PM_(3.0-5.0)颗粒物浓度差异均无统计学意义(P>0.05);多功能空气消毒机组消毒后PM_(0.3-1.0)、PM_(1.0-3.0)、PM_(1.0-5.0)、PM_(3.0-5.0)颗粒物浓度均较消毒前明显降低,差异均有统计学意义(P<0.05)。细菌菌落总数比较:消毒后患者入室后15、20 min,多功能空气消毒机组空气细菌菌落总数均明显低于紫外线消毒组,且差异有统计学意义(P<0.05)。杀菌率比较:在患者入室后15、20 min时,多功能空气消毒机组的杀菌率均明显高于紫外线消毒组,差异有统计学意义(P<0.05)。结论多功能空气消毒机对急诊抢救室的空气净化效果和空气消毒效果优于紫外线消毒,适合在临床推广使用。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[PM_(0.3)(particulate matter with diameter≤0.3μm in the air,and so on),PM_(0.5),PM_(1.0),PM_(3.0),PM_(5.0)]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 PM_(0.3-1.0),PM_(1.0-3.0),PM_(1.0-5.0)and PM_(3.0-5.0)concentrations between the two groups(P>0.05).After disinfection,the PM_(0.3-1.0),PM_(1.0-3.0),PM_(1.0-5.0)and PM_(3.0-5.0)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 PM_(0.3-1.0),PM_(1.0-3.0),PM_(1.0-5.0)and PM_(3.0-5.0)particulate concentrations in the ultraviolet disinfection group before and after disinfection(P>0.05).The particulate concentrations of PM_(0.3-1.0),PM_(1.0-3.0),PM_(1.0-5.0)and PM_(3.0-5.0)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 th
