Potential Long Term Benefits of Acute Hypothermia after Spinal Cord Injury: Assessments with Somatosensory Evoked Potentials

Crit Care Med, 2012 · DOI: 10.1097/CCM.0b013e318232d97e · Published: February 1, 2012

Simple Explanation

This study explores if cooling the body after a spinal cord injury can help protect the nerves and improve recovery. Rats with spinal cord injuries were either cooled for a short time or kept at a normal temperature, and their nerve signals and movement were checked. The results showed that cooling helped the rats' nerves work better and improved their movement, suggesting it could be a useful treatment.

Study Duration

4 weeks

Participants

21 Female Lewis Rats

Evidence Level

Not specified

Key Findings

1
Hypothermia group showed significantly higher SSEP amplitudes post-injury compared to controls.
2
BBB scores were also higher immediately after injury and 4 weeks later in the hypothermia group.
3
Histological evaluations showed more tissue preservation in hypothermia group.

Research Summary

Post-SCI, early systemic hypothermia provided significant neuroprotection weeks after injury via improved sensory electrophysiological signals in rats. This was accompanied by higher motor behavioral scores and more spared tissue in acute and post-acute periods after injury. Preservation of sensory pathways early after injury suggests that acute hypothermia may be potentially beneficial for long-term recovery.

Practical Implications

Therapeutic Intervention

Early systemic hypothermia may be a useful therapeutic intervention following spinal cord injury.

Improved Recovery

Hypothermia promotes recovery from the initial impact of the injury itself.

Future Research

Further studies are needed to determine the mechanisms of hypothermia after SCI in the SSEP pathways.

Study Limitations

1
The study was conducted on rats, and results may not directly translate to humans.
2
The mechanisms underlying the neuroprotection by hypothermia have eluded researchers.
3
BBB testing while assessing locomotor activity does not necessarily correlate with the functional integrity and neurological conduction of the spinal cord.
