Background Intubation using a flexible optical scope (FOS) is a cornerstone technique for managing the predicted and unpredicted difficult airway. The term FOS covers both fibre‐optic scopes and videoscopes. The total costs of using flexible scopes for intubation are unknown. The recent introduction of a disposable flexible scope for intubation merits closer scrutiny of the total costs associated with both modalities. Methods The costs incurred during intubations using FOSs at a large anaesthesia department were identified, and a series of intubations using a disposable scope were analyzed for comparison. Recognized health‐economic methodology was applied. Results During a 1‐year period, 360 FOS intubations were performed. In this clinical setting, the average cost of an intubation using a reusable FOS was €177.7. When using the disposable Ambu® aScope (Ambu A/S, Ballerup, Denmark), the cost was €204.4. The break‐even point, i.e. the number of intubations per month where the cost of using disposable and non‐disposable equipment is identical, was 22.5/month. A subgroup analysis looking solely at intubations performed with flexible videoscopes revealed that the cost per intubation was equal for disposable and reusable videoscopes. Conclusion At our institution, the total cost of an intubation is greater when using disposable compared with reusable equipment (€204.4 vs. €177.7). If video equipment with an external monitor is considered mandatory, the expenses are of equal magnitude. The cost analysis is particularly sensitive to the actual number of flexible optic intubations performed; with fewer intubations, the total cost will begin to favour disposable equipment.
