IntroductionSeveral options exist with regard to flexible pharyngo-laryngoscope sterilisation. We audited the use of disposable sheaths in our department over a six-month period.MethodsA cost-analysis was performed and the advantages and disadvantages of this system were compared with several alternative options.ResultsWe found that the overall cost of disposable sheaths averaged ł4008 per month over a six-month period. We subsequently introduced chlorine dioxide (ClO2) wipes as a means of disinfection. Chlorine dioxide wipes have enabled a monthly saving of ł3145 over sheath usage. Additionally, they meet health regulation requirements and are a convenient, cost-effective alternative to sheaths.DiscussionThe limiting factors, including time and financial issues, involved in nasendoscope disinfection are discussed.ConclusionsWe have found chlorine dioxide wipes to be a satisfactory alternative means of nasendoscope disinfection. Possible time constraints aside, there are no advantages of sheath use over our current method. Chlorine dioxide wipes are also preferable from a financial point of view.
