The safety of orotracheal intubation in patients with unstable cervical spine fracture or high spinal cord injury.

BACKGROUND

The potential merits and dangers of orotracheal and nasotracheal intubation in patients with injury to the cervical spine or spinal cord continue to be debated. To address this issue, a prospective study was conducted at a level 1 trauma center in patients with respiratory embarrassment and either or both of these injuries.

MATERIALS AND

METHODS

Over a 7-year period, all such patients underwent neurologic examination by a trauma surgeon on arrival at the trauma center, immediately after endotracheal intubation, and at frequent intervals throughout hospitalization. Cervical immobilization was maintained manually during endotracheal intubation. When necessary, patients were sedated or paralyzed with short-acting pharmacologic agents.

RESULTS

During the study period, there were 81 patients with 98 cervical vertebral body fractures, but without evidence of spinal cord injury on initial examination. Sixty-seven patients (83%) were legally intoxicated, and 12 patients had closed head injury. Endotracheal intubation was performed in 26 patients with unstable fractures, and 22 patients were intubated via the oral route. No patient manifested a subsequent neurologic deficit. Sixty-nine additional patients presented with high spinal cord injury; 16 had no cervical spine fracture, and 53 patients had 61 fractures of the cervical vertebrae. Sixty patients (87%) were intoxicated, and 8 patients had closed head injury. Endotracheal intubation was performed in 29 of these patients, and 26 patients were intubated via the oral route. No patient experienced further neurologic deficit following endotracheal intubation.

CONCLUSION

In trauma victims with or at high risk of cervical spinal cord injury, orotracheal intubation is a rapid, safe means of achieving airway control.
