Spinal Cord Injury ll: Pathophysiology

43
Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Summary

Current spinal motion restriction guidelines lack evidence for first aid providers. This review highlights research gaps, especially concerning layperson application and low-resource settings, to inform future recommendations.

Area of Science:

  • Emergency Medicine
  • Trauma Care
  • Evidence-Based Practice

Background:

  • Spinal motion restriction (SMR) protocols are standard for Emergency Medical Service (EMS) professionals managing suspected spinal injuries.
  • Existing guidance for lay first aid providers is limited and debated, with concerns about potential harm from cervical collars.
  • A comprehensive evidence review is needed to clarify SMR effectiveness and inform policy for all first responders.

Purpose of the Study:

  • To scope the literature published since 1999 on the effectiveness of prehospital cervical spinal motion restriction.
  • To identify research gaps in the evidence base for SMR, particularly concerning first aid providers and diverse settings.
  • To support the International Liaison Committee on Resuscitation's evidence evaluation process.

Main Methods:

  • A scoping review of literature from 1999 to July 2024, searching MEDLINE, Embase, and CINAHL Plus.
  • Included studies compared SMR with no SMR or different SMR techniques.
  • Data were synthesized narratively with frequency counting and visualized in evidence gap maps.

Main Results:

  • Sixty-six studies were included; 76% of experimental studies used live human volunteers to assess cervical motion and adverse effects.
  • Observational studies focused on secondary injury risk, functional outcomes, and adverse effects in trauma patients.
  • Crucially, no studies involved SMR application by trained or untrained first aid providers; only two explored improvised devices.

Conclusions:

  • Significant research gaps exist regarding SMR use by first aid providers, in low- and middle-income countries, and for pediatric populations.
  • Further research is needed on improvised SMR devices for low-resource settings.
  • This review provides a foundation for future systematic reviews to develop evidence-based first aid recommendations for spinal injuries.
