Ultrasound reveals how a neck nerve block may impact the diaphragm
NCT ID NCT07722052
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This study uses ultrasound to measure diaphragm movement and breathing in 15 adults receiving a stellate ganglion block — a nerve injection for certain pain conditions. The goal is to see how often the block temporarily paralyzes one side of the diaphragm. Researchers also check lung function with a breathing test.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- ultrasound-guided stellate ganglion block with levobupivacaine
- What this could lead to
- If the block rarely affects breathing, it may be safer than thought for treating certain pain conditions.
- What could go wrong
- This is a very small observational study with only 15 people, so results may not apply widely. The block itself carries risks like nerve injury or bleeding.
