Regional CBF in chronic stable TBI treated with hyperbaric oxygen.

Area of Science:

• Neurology
• Neurosurgery
• Hyperbaric Medicine

Background:

• Chronic traumatic brain injuries (TBI) can lead to persistent neurologic deficits and altered cerebral blood flow.
• Hyperbaric Oxygen Therapy (HBO2) is a potential treatment modality, but its efficacy in TBI requires further investigation.

Purpose of the Study:

• To evaluate the effectiveness of HBO2 in improving neurologic deficits and regional cerebral blood flow (rCBF) in individuals with chronic TBI.
• To assess changes in neurological function, neuropsychometric performance, and cerebral perfusion following HBO2 treatment.

Main Methods:

• A nonrandomized control pilot trial was conducted with five TBI subjects receiving HBO2.
• Control groups included five matched head-injured controls (HIC) and five healthy normal controls.
• SPECT brain scans were used to analyze rCBF, alongside neurologic, neuropsychometric, and exercise testing, and MRI/CT scans.

Main Results:

• No significant objective improvements were observed in neurologic, neuropsychometric, or exercise testing outcomes.
• Regional cerebral blood flow (rCBF) analysis using Statistical Parametric Mapping on SPECT scans showed no significant changes.
• No significant changes were detected in MRI or CT scans following HBO2 treatment.

Conclusions:

• This small pilot study suggests that HBO2 did not significantly improve clinical outcomes or rCBF in patients with chronic TBI.
• The findings indicate a need for more extensive research to determine the role of HBO2 in TBI management.
