Abstract
Objective To evaluate the feasibility of slightly acidic electrolyzed oxidizing water for the disinfection of gastrointestinal endoscopes. Methods Electrolyzed oxidizion water generator was utilized to produce the water, which was applied for the disinfection of gastrointestinal endoscopes. The disinfectant efficiency and effect were evaluated. Results A total of 215 samples were taken for bacterial culture after the disinfection. The mean sterilization efficiency of slightly acidic electrolyzed oxidized water and 2% glut- araldehyde by machine were 99. 92% and 99. 85% , respectively, while the mean sterilization efficiency were 99. 85% and 99. 84% by manual disinfection. There were no statistical significance between the two groups. The effective rates of both groups were 100%. No deformation or aging was observed in the endoscopes. The disinfectant caused no damage to the cleansing and disinfection. Conclusion It is feasible to apply slightly acidic electrolyzed oxidizing water to the disinfection of endoscopes.
