Cervical Spine Anesthesia: Airway, Positioning, and Autonomic Hyperreflexia

Anesthetic management of patients with cervical spine pathology — unstable C-spine airway, prone/sitting positioning, and autonomic hyperreflexia in SCI ≥ T6.

Cervical spine anesthesia centers on three pillars: (1) airway management that minimizes C-spine motion while securing oxygenation, (2) positioning (prone, sitting, beach-chair) with attention to spinal cord perfusion and venous air embolism, and (3) recognition and treatment of autonomic hyperreflexia in any patient with SCI at T6 or above.

If you forget

HEADLINE: Immobilize first, oxygenate always — first-pass success beats zero motion.

Board trap
Examiner asks: 'Your patient with a C5–C6 fracture has a BP of 210/110 during bladder distension — what is the mechanism and first drug?' Answer: unopposed sympathetic outflow below the lesion in SCI ≥ T6; first-line is a short-acting antihypertensive (nitroglycerin, nicardipine, or nitroprusside), NOT a long-acting beta-blocker.

Key numbers

  • SCI at T6 or higher → risk of autonomic hyperreflexia (SNACC 2020).
  • ISP target < 15 mmHg; CSF drained in 10 mL/h aliquots (AAA/SVS 2022).
  • Second-generation SAD preferred over first-generation (DAS 2024, Grade D strong).
  • First-pass success and oxygenation prioritized over zero cervical motion (DAS 2024).
  • Sitting-position VAE: sudden ETCO2 drop is the earliest reliable sign (SNACC 2020).
