Interventions to Optimize Spinal Cord Perfusion in Patients with Acute Traumatic Spinal Cord Injuries: A Systematic...

Area of Science:

• Neuroscience
• Traumatology
• Critical Care Medicine

Background:

• Optimizing spinal cord perfusion pressure (SCPP) is crucial for managing acute traumatic spinal cord injuries (SCI).
• Current interventions supporting mean arterial pressure (MAP) or SCPP face controversy regarding efficacy and safety.
• Neurological recovery and adverse event risks associated with these interventions require thorough investigation.

Purpose of the Study:

• To determine the effects of optimizing spinal cord perfusion on neurological recovery in acute traumatic SCI patients.
• To assess the risks of adverse events associated with interventions aimed at supporting MAP or SCPP.
• To synthesize current evidence on the efficacy and safety of spinal cord perfusion optimization strategies.

Main Methods:

• Systematic literature search across multiple databases for published and unpublished reports.
• Independent screening, data extraction, and risk of bias assessment by two reviewers.
• Data synthesis and confidence evaluation using the GRADE approach.

Main Results:

• Low to very low quality evidence indicates uncertain effects of MAP support on neurological recovery.
• Vasopressor use for MAP support may increase cardiac adverse events.
• Increased SCPP potentially linked to improved recovery, but monitoring carries risks like CSF leakage.
• Limited comparative data exists for specific MAP/SCPP goals or monitoring techniques.
• Norepinephrine may have fewer adverse events than dopamine, based on very low-quality evidence.

Conclusions:

• Current literature provides insufficient evidence for strong recommendations on MAP or SCPP support in acute traumatic SCI.
• Individualized treatment approaches may be optimal given the data limitations.
• Further research is warranted to clarify the risks, benefits, and alternatives for spinal cord perfusion support in SCI patients.
