Postoperative Central Cord Syndrome: Physiologic Decapitation in the PACU

Abstract

Central cord syndrome is a form of incomplete spinal cord injury appearing in the anesthesia literature primarily in trauma. Our institution recently managed a rare, life-threatening central cord syndrome following an uneventful anterior cervical discectomy and fusion which uniquely presented as respiratory depression progressing to quadriplegia. This patient's dramatic experience began nearly indistinguishably from more common etiologies of respiratory depression in the post-anesthesia care unit before blossoming swiftly into quadriplegia. We review the details of her presentation and pathophysiology with a message of vigilance to the anesthesia provider. Interpretation of her clinical exam and rapid intervention were key to preventing a lethal outcome. Central cord syndrome should be considered by anesthesiologists in the differential for respiratory depression following cervical spine surgery.
