Abstract

Introduction:

Flexible nasoendoscope is an important tool in otorhinolaryngology practice. The endoscope needs to be decontaminated prior to use in the next patient. The 2005 ENT-UK guidance for cleaning fibre-optic laryngoscopes stated that the ideal disinfecting agent and process should be effective and have low capital and maintenance costs.

Objective:

To compare the efficacy and cost-effectiveness of chlorine dioxide wipes versus automated washer, for decontamination of flexible nasendoscopes.

Methods:

A sequential cohort, in vitro study was performed to test the efficacy of chlorine dioxide wipes and automated washer. Costs were also calculated.

Results:

After deliberate bacterial contamination of the nasendoscope and subsequent decontamination, swab samples from the endoscope showed Staphylococcus epidermidis growth in 2 per cent (1/50 swabs) of the chlorine dioxide wipe group and in 28 per cent (14/50 swabs) of the automated washer group (p = 0.00). Based on a projected 10-year cost calculation, the automated washer was cheaper.

Conclusion:

Further studies are required to test whether these results are replicable. A similar study should be performed using real patients, to check the significance of improper decontamination.
