Effect Evaluation on Electrolyzed Oxidizing Water Used in Disinfection of Skin Test Instead of 75% Ethanol

Objective To verify the feasibility of acidic electrolyzed oxidizing water to replace the 75% ethanol for skin disinfection,so as to provide an experimental evidence to seek the optimal clinic-appropriate disinfectant.Methods Totally 68 medical workers,nurses and their families were enrolled in the study.Four test areas were formed in both forearm ulnar skin,with one area as a control,and the remaining three districts were disposed by 75% ethanol,saline,and electrolyzed oxidizing water respectively.Then we take samples from the skin after 1 minute,and culture them to count bacteria units to evaluate the disinfectant outcomes.Results The three kinds of disinfectant could significantly reduce culturing bacteria(P0.01).The sterilization quantity of saline was significantly less than that of 75% ethanol(P0.05).Disinfection effects indicated that 75% ethanol and acidic electrolyzed oxidizing water were qualified for clinical disinfectant,while sterile saline was not recommended for sterilization.Electrolyzed oxidizing water and saline did not cause local skin reactions,while 75% ethanol accounted for 5.9% of allergic skin reaction.Conclusion 75% ethanol to the skin test shows good natural bacteria killing effect.Saline can not be used as a disinfectant due to its partial clear effect,so acidic electrolyzed oxidizing water has a good disinfectant effect,without allergic reaction,and thus it can be used as an alternative disinfection before skin test.
