Overall approach to a difficult airway
- Always ask for help!
- The goal is oxygenation, not intubation
- Your first attempt is your best attempt
- Don’t panic!
Preoperative Assessment (check out Episode 1 of the series for a review!)
- Identify risk factors for a potentially difficult airway:
- Difficult ventilation
- Difficult intubation
- Difficulty with patient cooperation/consent
- Difficult cricothyrotomy
- One of the best predictors of a difficult airway is a history of difficult airway
Scenario 1: Can't intubate, can ventilate
- Return to BMV (bag-mask ventilation) to stabilize the patient and give yourself time
- Try something new with each attempt:
- Switch to a more experienced operator
- Optimize patient position
- Ask an assistant to apply BURP (backwards upwards rightwards pressure)
- Try with different equipment (such as a different size ETT, a Bougie, or videolaryngoscope)
- Minimize the number of attempts (max. 3)
- Consider using a supraglottic airway device or waking the patient up
Scenario 2: Can't intubate, difficult ventilation
- Improve BMV technique:
- Use an oropharyngeal or nasopharyngeal airway
- Optimize patient position
- Ensure the mask has a tight seal, use 2 hands and ask someone else to bag
- Try inserting a supraglottic airway device
- Once oxygenation is achieved, consider your options for establishing an airway or waking the patient up
Scenario 3: Can't intubate, can't oxygenate
- Recognize the problem and communicate with the team
- Proceed with cricothyrotomy / surgical airway
