Meta-analysis on disinfectant efficacy of air disinfector / 中国感染控制杂志

ABSTRACT

Objective To evaluate disinfectant efficacy of air disinfector and ultraviolet lamp.Methods Domestic literatures were searched by computer,RevMan 5 .3 software provided by the Cochrane collaboration was used for quantitative analysis,efficacy of two kinds of air disinfection methods was compared. Results A total of 1 1 articles met the inclusion criteria. Because the heterogeneity of literatures,random effects model analysis was adopted, colony forming unit (CFU)before disinfection(WMD= -26.28,95% CI[-60.31,7.75],P>0.05 )and immediately-after disinfection(WMD= 22.45,95% CI[-34.24,79.13],P>0.05)had no obvious difference between two methods respectively,but CFU of air disinfector 2 hours after disinfection was significantly less than ultraviolet lamp group(WMD= -345.11,95% CI[-478.28,-211.94],P<0.05).Conclusion Air disinfector has good continuous disinfection efficacy.
