The difficult airway on oral boards
Examiners want a plan before induction, a backup, and a clear point at which you change course.
Last reviewed October 2026. Guidelines change — check the ASA guideline and your institution’s algorithm.
Before induction: assess and plan
Start with the history (prior difficult airway, obstructive sleep apnea, head and neck surgery or radiation) and a focused exam. Then say whether you expect difficulty with mask ventilation, supraglottic airway, laryngoscopy, intubation or a surgical airway, and whether there is a risk of aspiration or rapid desaturation. The 2022 ASA guidelines organize decisions around these factors.
Awake or asleep?
If difficulty is predicted, explain whether you would secure the airway awake and why. Name the preparation in general terms: explain to the patient, topicalize, use judicious sedation that preserves spontaneous breathing, and choose a device such as a flexible scope or video laryngoscope. Say what you would do if awake intubation fails or is not possible.
Unexpected difficulty after induction
- Call for help and the difficult airway cart.
- Keep oxygenating: mask ventilation, supraglottic airway.
- Limit intubation attempts and change something each time (device, operator, position).
- Consider waking the patient up if you can oxygenate and the case can wait.
- If you cannot intubate and cannot oxygenate, move to an emergency invasive airway without delay.
After the event
Examiners often finish with extubation planning and follow-up: extubate when criteria are met with a plan for reintubation, then tell the patient, document the difficulty, and make sure future clinicians know. That last part also fits the communication topics on the OSCE outline; see OSCE tips.
