Less lidocaine, same relief: study seeks minimum dose for arm block
NCT ID NCT07374952
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study aims to find the smallest amount of lidocaine needed to successfully numb the arm using a specific ultrasound-guided nerve block technique. Researchers will test different volumes of lidocaine in 60 adults aged 18-70, adjusting doses based on previous results. The goal is to maintain effective pain relief while using less medication, potentially reducing side effects.
What this could mean

- lidocaine
- What this could lead to
- If successful, this could help doctors use less lidocaine for arm nerve blocks, reducing side effects while still providing effective pain relief.
- What could go wrong
- This is a small, early-phase dose-finding study with only 60 participants, so results may not apply to all patients or settings.
