Effect of technique and timing of tracheostomy in patients with acute traumatic spinal cord injury undergoing mechanical ventilation.

OBJECTIVE: To assess the effect of timing and techniques of tracheostomy on morbidity, mortality, and the burden of resources in patients with acute traumatic spinal cord injuries (SCls) undergoing mechanical ventilation. DESIGN: Review of a prospectively collected database. SETTING: Intensive and intermediate care units of a monographic hospital for the treatment of SCI. PARTICIPANTS: Consecutive patients admitted to the intensive care unit (ICU) during their first inpatient rehabilitation for cervical and thoracic traumatic SCI. A total of 323 patients were included: 297 required mechanical ventilation and 215 underwent tracheostomy. OUTCOME MEASURES: Demographic data, data relevant to the patients' neurological injuries (level and grade of spinal cord damage), tracheostomy technique and timing, duration of mechanical ventilation, length of stay at ICU, incidence of pneumonia, incidence of perioperative and early postoperative complications, and mortality. RESULTS: Early tracheostomy (<7 days after orotracheal intubation) tracheostomy was performed in 101 patients (47%) and late (> or = 7 days) in 114 (53%). Surgical tracheostomy was employed in 119 cases (55%) and percutaneous tracheostomy in 96 (45%). There were 61 complications in 53 patients related to all tracheostomy procedures. Two were qualified as serious (tracheoesophageal fistula and mediastinal abscess). Other complications were mild. Bleeding was moderate in one case (late, percutaneous tracheostomy). Postoperative infection rate was low. Mortality of all causes was also low. CONCLUSION: Early tracheostomy may have favorable effects in patients with acute traumatic SC. Both techniques, percutaneous and surgical tracheostomy, can be performed safely in the ICU.

Tracheostomy in spinal cord injured patients.

Patients with cervical spinal cord injury frequently need prolonged mechanical ventilation as a result of worsening pulmonary vital capacity due to paralysis of respiratory muscles, severe impairment of tracheobronchial secretions clearance and high incidence of respiratory complications like pneumonia or atelectasis. Patients with thoracic spinal cord injury may need mechanical ventilation due to associate injuries. For these reasons, tracheostomy is frequently performed in these patients, more frequently when the spinal cord injury is at cervical level. Percutaneous technique, performed in the ICU, should be considered the preferred procedure for performing elective tracheostomies in spinal cord injured patients. Tracheostomy should be implemented as soon as possible in SCI patients they require prolonged mechanical ventilation. Tracheostomy can be performed just after anterolateral cervical spine fixation surgery. Tracheostomy can be removed when no longer needed without major complications.
