Difficult Airway Algorithm in Suspected Cervical Instability

Securing oxygenation and first-pass success without worsening spinal cord injury

When cervical instability is suspected, the difficult airway algorithm must explicitly integrate manual in-line stabilization, optimize first-pass success with a chosen device, and pre-stage supraglottic and front-of-neck rescue — because both hypoxia and excess motion cause permanent neurologic harm.

If you forget

BALANCE oxygenation + first-pass success + motion minimization — never motion alone

Board trap

Stem: 'Cervical collar on, MILS held, you cannot mask ventilate and SpO2 is falling — what now?' Answer: mask failure is a rescue oxygenation trigger — insert supraglottic airway with MILS in place; do not remove MILS to 'improve seal' and do not repeat laryngoscopy.

Key numbers

4 pillars of cervical-spine airway plan: immobilization, device choice, operator expertise, rescue oxygenation (DAS 2024)
Awake intubation has 4 triggers: difficult ventilation, aspiration risk, brief-apnea intolerance, difficult emergency invasive access (ASA 2022)
Airway plan requires 4 elements: attempt limits, oxygen delivery, backup technique, rescue progression (ASA 2022)
