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,P0.05).[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.
