Failed Airway
ADU-07
Diagnosis
2 unsuccessful intubation attempts by an airway expert in a patient under general anesthesia
Call for help and a code cart
- Ask: "Who will be the crisis manager?"
- Crisis manager designates checklist reader
Get difficult airway cart
Monitor elapsed TIME, intubation ATTEMPTS, and SpO2
- Limit attempts to 3 by initial provider plus 1 attempt by other airway expert (“3+1”)
Bag-mask ventilation with 100% Oxygen
- Is ventilation adequate?
- Maintaining adequate SpO2?
- Capnographic evidence of adequate ventilation?
- Is ventilation adequate?
Ventilation NOT ADEQUATE
- Consider/attempt supraglottic airway
- Optimize patient position
- If unsuccessful, attempt alternative intubation approaches as you prepare for emergency invasive airwayy
- Limit to “3+1”
- If you remain unable to intubate and unable to ventilate, implement emergency invasive airway
Switch list if ventilation status changes
- Consider/attempt supraglottic airway
Ventilation ADEQUATE
- Attempt alternative intubation techniques
- Limit to “3+1”
- Consider doing the procedure with a supraglottic or mask airway
- Optimize ventilation/intubating conditions
- Consider invasive airway
- Consider awakening patient
- If awakening patient, consider:
- Awake intubation
- Complete procedure under local or regional
- Cancel the procedure
Switch list if ventilation status changes
- Attempt alternative intubation techniques
