New anesthetic may spare the diaphragm during arm surgery
NCT ID NCT07263295
First seen Jun 27, 2026 · Last updated Aug 04, 2026 · Updated 2 times
Summary
This study compares two types of numbing medicine for upper limb surgery: a standard one and a longer-acting version. Researchers want to see how quickly the diaphragm (the main breathing muscle) recovers after the nerve block. 120 adults having arm or hand surgery will be split into two groups and monitored for breathing function and pain. The goal is to find out if the newer anesthetic causes less breathing trouble.

- Active substance
- Liposomal bupivacaine and standard bupivacaine (hydrochloride bupivacaine)
- What this could lead to
- If successful, this could help doctors choose a nerve block that reduces breathing side effects after upper limb surgery.
