Effect evaluation of electrolyzed oxidizing water for disinfection in ICU environment

Objective To compare the disinfectant effect of acid electrolyzed oxidizing water (EOW)with that of chlorine-containing disinfectant in ICU environment.Methods The floors, computer keyboards, telephone keypads, ward tables and instrument panels were sampled respectively before and after disinfection in ICU. Then the bactericide effect was compared between samples by EOW or by chlorine-containing disinfectant.Results The average kill rate of EOW was 97.6%, and that of chlorine-containing disinfectant was 95.7%. The mean difference values of bacterial colonies were done for t test before and after disinfection, which indicated that the disinfectant effect of EOW was superior to that of chlorine disinfectant (t=2.12,P＜0.05).Conclusion EOW is proved to be better than chlorine-containing disinfectant in disinfection, and also in economical and social benefits. Therefore, it is thought to be an ideal choice for disinfection in ICU and hospital environment.
