First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study compares two ultrasound-guided nerve block techniques for adults having surgery on the lower arm or hand. The goal is to see which method numbs the arm faster. Fifty participants will receive either a costoclavicular or a lateral-sagittal infraclavicular block using a mix of lidocaine and bupivacaine. The time to full numbness and muscle relaxation will be measured.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: lidocaine and bupivacaine (local anesthetics)
What this could lead to: If one method proves faster, it could reduce waiting time for surgery and improve patient comfort.
What could go wrong: This is a small, early-stage trial with only 50 participants, so results may not apply to everyone. Both blocks are already used in practice, so no major breakthrough is expected.
