Extubation of patients with cervical spine injury

Extubation in cervical spine injury

Abstract

Background and purpose: Extubation in patients with cervical spine injury (CSI) is a high-stakes clinical intervention, requiring a nuanced understanding of spinal pathophysiology, respiratory mechanics, and risk mitigation strategies. This review synthesizes the current evidence on the demographics, injury mechanisms, and extubation risks associated with CSI, highlighting the complexities that arise from associated spinal cord injuries, diaphragmatic dysfunction, and airway instability.

Results: Epidemiological data reveal a bimodal age distribution and an increasing incidence of CSI due to falls, especially among the elderly. The anatomical vulnerability of the cervical spine and the two-phase pathophysiology of spinal cord injury—primary mechanical insult and secondary inflammatory cascades—complicate respiratory management and timing of extubation. Patients with CSI often face unique extubation challenges, including impaired airway reflexes, agitation, and upper airway edema. Existing guidelines, such as those from the Difficult Airway Society, underscore the need for high-risk extubation protocols, emphasizing preparedness, appropriate sedation, and airway reflex control strategies like remifentanil infusion or delayed extubation in select cases. Several predictors of extubation failure in patients with CSI have been investigated, such as prolonged surgery, vertebral level involvement and blood loss.

For ventilator-dependent tetraplegic patients, individualized weaning strategies based on neurological and diaphragmatic function are crucial. The use of adjuncts like cough-assist devices post-extubation is essential for airway secretion clearance.

Conclusion: Safe extubation in CSI patients demands a multidisciplinary, protocol-driven approach tailored to individual pathophysiological and surgical risk profiles.
