The difficult airway

Background

• ASA Difficult Airway Algorithm does not necessary apply to the ED since the patient can always be awakened and case cancelled

Pre-Intubation

See:

• Predicting the difficult airway
• Apneic oxygenation

Difficult Intubation

• Advanced airway adjuncts

Intubation Options

Intubation Type	Pros	Cons
Traditional
Awake intubation
Nasal intubation		Lower success rate Higher complication rate (e.g. bleeding, emesis, and airway trauma) Do not attempt in patients with posterior pharyngeal swelling such as in angioedema
Retrograde intubation		Need time to set up Risk hematoma, pneumothorax
Fiberoptic bronchoscopic intubation		Takes time to set up Limited by secretions, bleeding, poor suction,

Surgical Airways

A surgical airway should always be the last step in patients with failure to oxygen and ventilate with BVM and inability to intubate

• Surgical cricothyrotomy
• Needle cricothyrotomy
• Pediatric jet ventilation
