Abstract
BACKGROUND: Nasendoscopes are widely used in the outpatient ENT setting. Their reprocessing requires high-level disinfection (HLD). Recently, a wiping procedure using chlorine dioxide (ClO2) has been proposed as an alternative to HLD traditional procedures. OBJECTIVE: To assess the effectiveness of the HLD wiping procedure versus soaking procedure on a contaminated nasendoscope. METHOD: A nasendoscope was contaminated with four strains of bacteria and Bacillus subtilis spores. After HLD either with the wiping procedure or with the soaking procedure (PA), the reduction of the initial contamination was determined. FINDINGS: The wiping procedure with ClO2 displayed more than 5 log reduction for vegetative bacteria after 30 s contact time (CT) and 4 log reduction on B. subtilis spores after 2 min CT. The soaking procedure with PA displayed similar results on planktonic bacteria after 10 min CT but the log reduction of B. subtilis remained below 4. CONCLUSION: The ClO2 wiping procedure showed bactericidal and sporicidal efficacy on a contaminated nasendoscope in a shorter time compared to the PA soaking procedure. Thus, ClO2 wiping procedure might be considered as an alternative to the traditional HLD procedure for nasendoscopes.
