Summary

This trial tests two types of nerve blocks—erector spinae plane block and rhomboid intercostal-subserratus plane block—for pain after laparoscopic gallbladder removal. About 80 adults having elective surgery will receive one of the blocks before the procedure. Researchers will measure pain scores, opioid use, and how well the diaphragm works to see which block offers better pain control and recovery.

What this could mean

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

Active substance
nerve block (local anesthetic injection)
What this could lead to
If one block works better, it could reduce opioid use and improve recovery after gallbladder surgery.
What could go wrong
This is a small, early-stage trial. Results may not apply to all patients, and nerve blocks carry rare risks like infection or allergic reaction.
