Effect of electrolyzed oxidizing water in disinfection of endoscopy

Objective: To detect the effect of electrolyzed oxidizing water (EOW) in disinfection of endoscopy and compared with 2% glutaraldehyde. Methods: Endoscopy was selected after being taken with patients in sequence according to the date. Specimens were obtained from endoscopic surface wiped with sterile gauze and biopsy channel rinsed with 10 ml of saline after being used immediately. One millilitre of the specimens was taken for bacterial culture. The same method was used to collect the specimens alter endoscopies were washed out and disinfected,respectively. Endoscope immersed in disinfectants,EOW and 2% glutaraldehyde,were 1,3 and 5 minutes,and divided into 3 groups ,respectively. Each group consisted of 30 cases.Results:After standard manual cleaning and disinfection for 1,3 and 5min in EOW, novegetative bacteria were found. In 2% glutaraldehyde processing group,5/30,4/30 and 1/30 specimens were bacteria positive after exposure for 1,3,5 minutes, respectively. P 1 (0.01) 0.05,P 3 (0.043) 0.05,P 5 (0.477)0.05.Conclusions: EOW shows more superiority in disinfection with high-speed and thoroughness than 2% glutaraldehyde.
