Predictive Factors Affecting the Need for Mechanical Ventilation in Acute Traumatic Cervical Spinal Cord Injury

Area of Science:

• Neurosurgery
• Traumatology
• Critical Care Medicine

Background:

• Acute traumatic cervical spinal cord injuries (TCSCI) can lead to neurogenic respiratory failure and the need for mechanical ventilation.
• Predicting early mechanical ventilation requirements in TCSCI, especially in lower cervical injuries without significant chest trauma, remains challenging.

Purpose of the Study:

• To identify primary predictors of early mechanical ventilation needs in patients with acute TCSCI.
• To evaluate the reliability of Computed Tomography (CT) versus Magnetic Resonance Imaging (MRI) in assessing spinal cord compression for predicting ventilation needs.

Main Methods:

• Retrospective analysis of 148 TCSCI cases treated between 2019 and 2022.
• Multivariate analysis to identify independent predictors of ventilatory support.
• Correlation and noninferiority testing comparing CT and MRI measurements of spinal cord compression.

Main Results:

• Spinal cord compression exceeding 25% on CT (aOR: 10.18) and cord contusion length of at least two levels on MRI (aOR: 2.11) were significant predictors of mechanical ventilation.
• CT measurements of spinal cord compression strongly correlated with MRI findings and reliably approximated them.
• Higher compression grades (≥2) were associated with increased ventilation risk and poorer patient outcomes, including lower survival rates and longer hospital stays.

Conclusions:

• Degree of spinal cord compression and cord contusion length are reliable, noninvasive predictors for early mechanical ventilation needs in TCSCI.
• CT imaging provides a reliable and cost-effective alternative to MRI for assessing spinal cord compression in this context.
• Early identification of these predictors aids in prognostic counseling, healthcare management, and potentially improving patient outcomes.
