Abstract:
BACKGROUND/AIMS: Conventional disinfectants are expensive, hazardous, and often require long periods of exposure. The aim of this study was to evaluate the effectiveness of a new endoscopic disinfector (Cleantop(R)) that uses superoxidized water (SW) as a disinfectant. METHODS: Immediately after patient examinations, endoscopes were cleaned manually and disinfected with SW for seven minutes. Cultures were taken from valves (swabbing), biopsy channels (rinsing), and biopsy channels after brushing (rinsing). The results were compared with those of other disinfectants tested previously by the same culture methods. RESULTS: Of 12 endoscopes disinfected with SW, disinfection rates were 83.3%, 58.3% and 25% at valves, channels and channels after brushing, respectively. In no instances were more than 100 colony forming units (cfu) of bacteria recovered from each endoscope. SW was similar to peroxygen compound (33.3%, 50%, 50%) and 2% glutaraldehyde (100%, 16.7%, 16.7%) in its disinfectant effect, since 100 or more cfu of bacteria were recovered only from endoscopes disinfected with peroxygen compound. The number of bacterial recovered from endoscopes disinfected with 2% glutaraldehyde was less than 10 cfu. CONCLUSIONS: Disinfection with SW appears to be an effective and time-saving alternative to conventional disinfectants.
