Introduction  \nThis airway assessment resource has been produced for use by ANZCA Fellows and trainees to improve understanding and guide management of airway assessment and difficult airways. It is the first of an airway resource series and complements the Transition to CICOresource document (and ANZCA professional document PS61), which are available on the ANZCA website.  \nThere are four components to this resource:  \nPart 1. Introduction.  \nPart 2. The traditional approach to normal and difficult airway assessment.  \nPart 3. The anatomical basis for airway assessment and management:  \ni) The “two-curve” theory.  \nii) The “three-column” approach.  \nPart 4. Airway device selection based on the two-curve theory and three-column assessment model.  \nOVERVIEW  \nThe role of airway assessment is to identify potential problems with the maintenance of oxygenation and ventilation during airway management. It is the first step in formulating an appropriate airway plan, which should incorporate a staged approach to manage an unexpected difficult airway or the institution of emergency airway management.  \nAirway assessment should be done for all anaesthesia encounters, including regional anaesthesia or monitored-care cases. This is despite evidence that current airway-assessment tools have a low positive predictive value for a difficult airway, because of low test sensitivity, modest test specificity, and the low prevalence of difficult or failed intubation in the general population. The aim of the assessment is to ensure any abnormalities are detected and an appropriate safe strategy is considered and employed, very much like making a diagnosis (assessment) and then treating (airway plan) . Yentis’s editorial made this point very eloquently in 20021 .  \n• The UK National Audit Project of Difficult Airway Management (NAP4) noted2 .  \n• There were deficiencies in the undertaking and/or recording of an airway assessment.  \n• Even when abnormalities were detected, the strategies adopted were not always likely to manage the problem successfully.  \nPoor judgement was the most common contributory factor.  \nIn an audit of 850 anaesthesia records, airway assessment documentation was deemed to be compliant in 59 per cent of cases and intraoperative airway device documentation was complete in only 76 per cent of cases3. This is not reassuring or helpful for subsequent anaesthesia on the same patient.  \nIn the event of a difficult airway being encountered, it is mandatory to provide written information to the patient and their medical practitioner, as well as to advise them to get a medical alert bracelet.  \n3 Airway Assessment  \nPart 2 of this resource identifies the following nine core airway management considerations, which should be used to determine the most appropriate airway plan in any patient:  \n1. Is there information about any previous airway difficulties?  \n2. Is there any altered cardiorespiratory physiology?  \n3. What is the impact of the surgery on the airway?  \n4. How difficult will it be to bag-and mask ventilate?  \n5. How difficult is it to place a supraglottic airway?  \n6. How difficult will it be to intubate the patient?  \n7. How difficult will it be to perform an infraglottic airway?  \n8. What is the risk of aspiration?  \n9.
