Abstract:
Objective Observation on the effect of disinfection on gastroscope, contaminated by hepatitis B surface antigen (HBsAg) in the electrolyzed oxidizing water(EOW). Methods Contaminated gastric juice and serum was added to EOW for 1 minute. Positive control samples were treated with PBS instead of EOW in the same way. Gastroscopes used for hepatitis patients were immersed in the EOW for 1 minute after cleaning. Samples were collected before and after treatment. ELISA was used to test HBsAg. Results With mixed samples (average S/N=42.16) of EOW， HBsAg became negative when diluted in 100 times. However, the HBsAg of positive control samples remained positive. After cleaning the gastroscope (average S/N=5.99) immersed in EOW, HBsAg became negative. Conclusion EOW was effective in destroying HBsAg which could be used for gastroscope disinfection.
