Due to advances in training, technology and guidelines implementation, elective airway management within the setting of the
Operating Room (OR) can be associated with very low complication rates [1]. There has been a heightened awareness and a steady rise in the amount of literature published on the prediction of difficult
airways for anaesthesia purposes. Unfortunately none of the suggested methods provide satisfactory results in terms of sensitivity
and specificity: at least for now, reliable prediction of difficult airway management (DAM) is likely to remain a decision-making
process based on clinical judgment, and this is particularly true in emergency situations and critical illness [2]. Furthermore, the epidemiology of DAM varies according to the different definitions used and the population studied in the
large amount of literature on the subject [3]. Complication rates in the Intensive Care Unit (ICU) environment are also much higher due to the inability, in the majority
of cases, to perform a thorough evaluation of the patient’s anatomy prior to airway instrumentation.
