Elective tracheal intubation in cervical spine injuries

Area of Science:

• Anesthesiology
• Neurosurgery
• Trauma Surgery

Background:

• Patients with unstable cervical spines face a high risk of iatrogenic spinal cord injury during tracheal intubation.
• Optimal anesthetic techniques for airway management in this population remain a subject of debate.

Purpose of the Study:

• To review and compare anesthetic techniques used for tracheal intubation in patients with unstable cervical spines.
• To assess the incidence of new neurological sequelae associated with different intubation methods.

Main Methods:

• Retrospective review of 45 patients undergoing tracheal intubation for unstable cervical spine stabilization over five years.
• Techniques included awake fiber-optic intubation with local anesthesia and general anesthesia (intravenous or inhalational) with neuromuscular blockade.
• All patients received weighted inline traction for cervical spine immobilization during intubation.

Main Results:

• No new neurological deficits were observed in any patient regardless of the intubation technique used.
• Awake fiber-optic intubation was performed in 27 cases, intravenous general anesthesia in 17, and inhalational general anesthesia in 1 case.
• Pre-operative neurological deficits were present in 16 patients.

Conclusions:

• The study suggests that no single anesthetic technique is definitively optimal for tracheal intubation in patients with cervical spine injuries.
• The consistent use of inline traction for cervical spine immobilization appears crucial in preventing further neurological injury.
• Further research may be warranted to establish definitive best practices.
