Spinal Cord InjurySurgeryResearch Methodology & Design

Simple Explanation

Suffering an acute spinal cord injury (SCI) is a catastrophic event and remains a great challenge for biomedical science; one that has stimulated and stymied decades of global research effort in search of effective treatment options to minimize or reverse paralysis and improve neurological outcome. Clinical practice guidelines can play an important role in evaluating and summarizing the available evidence, and then contextualizing it around the decision-making framework that clinicians are accustomed to working within on a daily basis This Focus Issue provides a snapshot of the existing evidence on these important SCI issues, and a methodologically rigorous framework for developing guidelines (when possible) to help clinicians in their decision-making.

Key Findings

  • 1
    Updated guidelines were established for the timing of surgical decompression after acute SCI, with surgical decompression within 24 hours of injury now “recommended” as a treatment option.
  • 2
    Updated guidelines were also established for hemodynamic management, with an expanded target range for mean arterial pressure (MAP) of 75-80 to 90-95 mmHg for between 3 to 7 days post-injury now “suggested” as a treatment option.
  • 3
    The GDG concluded that early surgical decompression (within 24 hours) be recommended as a treatment option, which reflects a stronger recommendation than what was generated in the 2017 guideline.

Research Summary

A rigorous process following GRADE standards was undertaken to review the available evidence and establish guideline recommendations around the role and timing of surgery in acute SCI, optimal hemodynamic management of acute SCI and the prevention, diagnosis and management of intraoperative SCI. Updated guidelines were established for the timing of surgical decompression after acute SCI, with surgical decompression within 24 hours of injury now “recommended” as a treatment option and hemodynamic management. This effort also identified key knowledge gaps and future directions for study, which will serve to refine these recommendations in the future.

Practical Implications

Surgical Decompression Timing

Early surgical decompression (within 24 hours) is recommended for acute SCI patients.

Hemodynamic Management

Maintain MAP between 75-80 and 90-95 mmHg for 3-7 days post-injury.

Intra-operative SCI Management

Use IONM in high-risk spine surgery cases and follow a care pathway for intraoperative management.

Study Limitations

  • 1
    Heterogeneity of SCI and variability in neurological recovery.
  • 2
    Relatively low incidence of ISCI, making it difficult to accrue large clinical experience.
  • 3
    Lack of high-quality evidence to substantiate a specific MAP threshold for hemodynamic management.
