Electricity meets ultrasound: a smarter way to target nerves?
NCT ID NCT06620471
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study explores whether measuring electrical impedance (tissue resistance) during ultrasound-guided nerve blocks can help doctors identify different tissues—like skin, fat, muscle, and nerves—more precisely. Researchers will test this in 100 adults receiving axillary, popliteal, or interscalene nerve blocks. The goal is to improve needle placement, boost block success, and reduce complications such as accidental injection into a nerve or blood vessel.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors place nerve block needles more accurately, potentially increasing success rates and lowering risks like nerve damage.
- What could go wrong
- This is an early observational study with only 100 participants, so results may not apply to all patients or settings. It measures tissue properties, not direct patient outcomes.
