Airway triage: a novel application-based method for airway assessment and risk stratification

Editor—Anaesthetists have searched for methods to predict difficult airways, but most methods are inaccurate.1–3 Current airway assessment methods focus mainly on anatomical factors. In a landmark study on airway assessment, Nørskov and colleagues4 found that 93% of difficult airways are still unanticipated, and only 25% are predicted correctly. This can lead to complications, and a better approach is needed. A novel application-based airway assessment and risk stratification method could lead to a reduction in the number of unanticipated airway management problems and therefore complications.
