Abstract:
Objective To select a practical and reliable method in cleaning and disinfecting endo-scope, and to investigate the efficacy of endoscope disinfection. Methods A study was done on the disinfection efficacy using or not using enzyme cleaning plus 2% glutaraldehyde immersion, and disinfection efficacy of automated washer/disinfectors for endoscopes at tertiary hospitals in Beijing. Results In 301 cases of en-doscopes cleaned with enzyme ( Epizyme rapid multi enzyme cleanse) and immersed in 2% glutaraldehyde for 7 minutes, culture was negative in 283 cases (94. 02% ) ; in 155 cases without enzyme cleaning but with immersion for 7 minutes in 2% glutaraldehyde, culture was negative in 137 cases (88. 39 % ). Taking 20 or less bacteria per endoscope as the eligibility criterion, there were 298(99.00% ) and 147(94. 84% ) cases eligible in enzyme treated and enzyme untreated group respectively , P
