Summary

Shoulder surgery often causes severe pain, and a nerve block is commonly used to numb the area. However, when the block wears off, many patients experience sudden intense 'rebound pain.' This trial tests whether a single-shot nerve block combined with an intravenous dose of the steroid dexamethasone can prevent rebound pain as effectively as a continuous nerve block that uses a catheter. The study involves 92 adults scheduled for shoulder surgery, and the main goal is to compare rebound pain scores in the first 24 hours after the block.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Dexamethasone (intravenous) plus single-shot nerve block
What this could lead to
If successful, this simpler approach could reduce rebound pain after shoulder surgery while avoiding the hassle and risks of a catheter-based continuous nerve block.
What could go wrong
This is a small Phase 4 trial with 92 participants, so results may not apply to all patients. The single-shot method might still lead to more rebound pain than the continuous block.
