Disinfection effects comparison of four methods on eye covers
Objective To compare the disinfection effects of four methods on cleaning and disinfecting eye covers.Methods A total of 120 eye covers used by patients were selected and divided into group A,B,C and D,with 30 covers in each group,which were dis-infected by using 500 mg/L chlorine disinfectant,75%ethanol,isopropyl alcohol complex quaternary ammonium salt disinfectant wipes,and moist heat disinfection,respectively.Before disinfection and at 5 min,4 h and 8 h after disinfection,microbial culture and ATP fluorescence detection were used to compare the qualified rates of disinfection,and the disinfection costs of the four groups were also compared.Results At 5 min after disinfection,the unqualified rates of disinfection of the four groups according to microbial culture and ATP fluorescence detection were 0;at 4 hours after disinfection,the unqualified rate of disinfection in group B was significantly higher than that of group D(P<0.008);and at 8 hours after disinfection,the unqualified rates of disinfection in group A,B and C weresignificantly higher than that of group D(all P<0.008).Conclusion The disinfection effect of moist heat disinfection method is significantly better than 500mg/L chlorine disinfectant,75%ethanol and isopropyl alcohol complex quater-nary ammonium salt disinfectant wipes,and it is simple and feasible.
