Mean arterial pressure (MAP) augmentation in traumatic spinal cord injuries: Early hyperperfusion treatment influences neurologic outcomes

The Journal of Spinal Cord Medicine, 2024 · DOI: 10.1080/10790268.2023.2223447 · Published: January 1, 2024

Simple Explanation

This study investigates how maintaining a specific blood pressure (MAP > 85 mmHg) affects recovery in patients with traumatic spinal cord injuries. The research focuses on the importance of achieving this blood pressure target early, particularly within the first 12-24 hours after the injury. Patients who maintained the target blood pressure more consistently in the initial hours showed better neurological outcomes, suggesting early blood pressure management is crucial.

Study Duration

3 Years

Participants

96 blunt traumatic spinal cord injured patients

Evidence Level

Retrospective study

Key Findings

1
Patients with neurological improvement had significantly higher average MAP values in the first 12 hours post-injury.
2
The 'No Improvement' group spent a significantly greater percentage of time below the target MAP of 85mmHg in the first 12 hours.
3
The area under the curve (AUC), representing the severity and duration of hypotension, was significantly higher in the 'No Improvement' group during the initial 12 hours.

Research Summary

This retrospective study evaluated the impact of early hyperperfusion therapy (MAP > 85 mmHg) on neurologic outcomes in blunt traumatic SCI patients. The key finding was that maintaining higher MAP values and minimizing time below the target MAP in the first 12 hours post-injury correlated with improved neurological outcomes. The study suggests that early and aggressive blood pressure management is crucial for optimizing neurological recovery in SCI patients.

Practical Implications

Early Intervention

Prioritize achieving and maintaining target MAP values (MAP > 85 mmHg) within the first 12 hours of treatment for blunt SCI patients.

Blood Pressure Monitoring

Implement rigorous blood pressure monitoring protocols to minimize hypotensive episodes during the critical early treatment period.

Transfer Considerations

Develop strategies to ensure consistent blood pressure management during patient transfers between facilities, as transferred patients may be particularly vulnerable to suboptimal MAP control.

Study Limitations

1
Retrospective study design limits intervention and data acquisition.
2
Unable to account for a reliable time of injury to initiation of hyperperfusion therapy for all patients.
3
Lack of long-term outcome data.
