Do’s in Penetrating Upper Airway Injury Awake Intubation

Do some deep breathing and self talk +/- visualization/deliberate mental rehearsal before managing the dangerous airway.

For awake intubation, do explain to the patient what you are doing. You need their co-operation to to maximize your chances of success. If you can’t get their co-operation consider ketamine.

Do have a triple set up ready. Video laryngoscope set to get a view of the vocal cords and ask assistant to hold it, then add flexible intubating scope; plus set up for cricothyrotomy as a default.

Do use an atomizer to administer 4% lidocaine such as EZ Spray (see video below) rather than a nebulizer.

Don’ts in Penetrating Upper Airway Injury Awake Intubation

Don’t wait to intubate a patient with a potential penetrating upper airway injury. The neck is a closed space. If you suspect that the patient with a penetrating neck injury has an airway that is obstructed, distorted or disrupted, they’re good until they’re dead. In other words, deterioration will be rapid and a panic situation will ensue.

Don’t choose RSI only because that’s what you’re most comfortable with. There are some situations where awake intubation, which most of us are not as familiar with, is preferred. If you aren’t’ familiar with awake intubation, practice with simulation.

If you do an RSI, don’t do anything blind because you can disrupt the upper airway further.

Don’t use positive pressure ventilation (no bagging, no supraglottic device) to avoid worsening subcutaneous emphysema.
