Management of C1-C2 Subluxation

Immediate Stabilization (First Priority)

The American College of Surgeons recommends immediate immobilization of the cervical spine with a rigid cervical collar and manual in-line stabilization to prevent neurological deterioration, maintain systolic blood pressure >110 mmHg, and transport directly to a Level 1 trauma center for definitive imaging and treatment 1, 2
Apply a rigid cervical collar with head-neck-chest stabilization immediately upon suspicion of C1-C2 subluxation to limit onset or worsening of neurological deficit, with evidence from the Anaesthesia journal 3, 1, 4
Use manual in-line stabilization (MILS) in conjunction with the rigid collar, as this significantly reduces complications despite the evidence being of low quality, according to the Anaesthesia journal 5, 1

Maintain systolic blood pressure >110 mmHg before and during injury assessment to reduce mortality, as recommended by the Anaesthesia journal 6, 1, 2
Target mean arterial pressure ≥70 mmHg continuously during the first week post-injury to limit neurological deterioration, according to Praxis Medical Insights 2
Place an arterial line for continuous accurate blood pressure monitoring, as suggested by Praxis Medical Insights 1

Obtain CT cervical spine without IV contrast as the initial imaging study for all patients with suspected C1-C2 subluxation, according to Praxis Medical Insights 4
Perform CT angiography if vascular injury is suspected, with a sensitivity of 90-100% and specificity of 98.6-100%, as recommended by Praxis Medical Insights 4

Remove the anterior portion of the cervical collar during intubation attempts while maintaining MILS to improve mouth opening and glottic exposure, as suggested by the Anaesthesia journal 5, 7, 1, 2
Use rapid sequence induction with direct laryngoscopy and a gum elastic bougie, according to the Anaesthesia journal 5, 6, 1
Do not use Sellick maneuver as it increases cervical spine movement, as recommended by the Anaesthesia journal 6, 1, 2

Never leave the cervical collar fully in place during intubation, as this significantly worsens glottic visualization and increases failure rates, according to the Anaesthesia journal and Praxis Medical Insights 7, 2
Do not allow systolic blood pressure to drop below 110 mmHg, as this increases mortality risk, as recommended by the Anaesthesia journal and Praxis Medical Insights 6, 1, 2
Avoid prolonged rigid collar immobilization beyond 48-72 hours without definitive treatment, as complications rapidly escalate after this timeframe, according to Praxis Medical Insights 4
Do not delay transport to a Level 1 trauma center, as this worsens morbidity, mortality, and neurological outcomes, as recommended by Praxis Medical Insights 1, 2

Begin joint range-of-motion exercises and positioning immediately upon ICU admission to prevent contractures, as suggested by Praxis Medical Insights 1
Implement comprehensive pressure ulcer prevention from the acute phase, according to Praxis Medical Insights 2
Prevent hypothermia aggressively, with a target core temperature of 36-37°C, as each 1°C drop reduces coagulation factor function by 10%, as recommended by Praxis Medical Insights 1
Consider early tracheostomy (<7 days) for upper cervical injuries with significantly decreased vital capacity, according to Praxis Medical Insights 1, 2
