Airway Trauma
Considerations
-
Emergency, full stomach
-
Trauma with ATLS approach
-
Difficult intubation & bag mask ventilation with possibility of complete obstruction
-
Plan for surgical airway backup
-
-
Co-existing injuries: unstable C-spine, traumatic brain injury, tracheobronchial disruption, vascular injury
-
Trauma considerations
Goals
-
Safe establishment of airway (spontaneous ventilation, get tube beyond injury)
-
Minimize C-spine movement
Conflicts
-
Full stomach vs difficult airway vs need for double lumen tube
-
Uncooperative or pediatric patient vs difficult airway
Airway Plan
-
Determine location of trauma: supraglottic, laryngotracheal, infracarinal
-
Bypass area of trauma during airway management
-
Supraglottic
-
Most preferred technique is tracheostomy
-
Awake vs. double setup after attempting direct laryngoscopy/video laryngoscopy/fiberoptic bronchoscopy
-
-
Laryngotracheal
-
Use awake, spontaneous ventilation technique under direct vision (fiberoptic bronchoscopy)
-
-
Infracarinal
-
Injury causing bronchopleural fistula with air leak, risk of tension pneumothorax &/or difficult ventilation during positive pressure ventilation
-
Secure airway with lung isolation: double lumen tube, bronchial blocker, single lumen tube placed endobronchially
-
Maintain spontaneous ventilation or rapid sequence induction while avoiding positive pressure ventilation until lung isolation
