Can a steroid make your shoulder numb longer after surgery?
NCT ID NCT07614802
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether adding dexamethasone (a steroid) to a standard pain-blocking injection (liposomal bupivacaine) can keep the shoulder numb longer after arthroscopic surgery. 80 adults aged 18-80 will be randomly assigned to get the block with or without the steroid. Researchers will call daily to see when feeling returns and track pain, opioid use, and side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- liposomal bupivacaine and dexamethasone
- What this could lead to
- If it works, this could provide longer-lasting pain relief after shoulder surgery, reducing the need for opioids.
- What could go wrong
- This is a small, early-phase study (80 people) testing a minor change to an existing technique. The benefit may be small or not apply to all patients.
