To the Editor, The correspondence from Wanderer et al. is of great interest and highlights the usefulness of guidelines in clinical decision-making for difficult airway management. Their longitudinal' data from a single institution show how difficult airway management may improve by following implementation guidelines. Nevertheless, this work also raises several questions. First, while the relationship between the introduction of the video laryngoscopes (VLS) and an increase in their utilization may seem intuitive, it is not as obvious why these authors report a reduction in the rate of fibreoptic intubations (FOI). Is it possible that VLS reduced the incidence of difficult intubations or that anesthesiologists have become more confident in rescuing an expected difficult intubation with VLS or supraglottic airways (SGAs)?
