What this trial studies

This study investigates the effects of different concentrations of bupivacaine in greater occipital nerve blockade for veterans suffering from post-traumatic headaches. Participants will receive three varying concentrations of bupivacaine, administered one week apart, to assess their acute and subacute sensations. The goal is to identify a suitable control dose for future efficacy trials, ultimately aiming to improve headache management in military servicemembers and veterans. This approach seeks to provide a safe and effective alternative to existing headache treatments that may have limitations.

Who should consider this trial

Good fit: Ideal candidates are U.S. military veterans within the VA Connecticut Healthcare System who experience chronic post-traumatic headaches.

Not a fit: Patients with skull defects or contraindications to bupivacaine will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could offer veterans a new, effective method for managing chronic post-traumatic headaches.

How similar studies have performed: Other studies have shown promise with similar nerve blockade techniques, suggesting potential for success in this approach.
