Summary

This study compares two ultrasound-guided nerve blocks to control pain after laparoscopic gallbladder removal. Seventy adults will receive either a modified thoracoabdominal nerve block or a recto-intercostal fascial plane block. The goal is to see which block reduces the need for opioid painkillers and improves recovery.

What this could mean

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

Active substance
bupivacaine
What this could lead to
If one block works better, it could offer a safer, opioid-sparing pain relief option for gallbladder surgery patients.
What could go wrong
This is a small, early-stage trial with only 70 participants. Results may not apply to all patients or surgeries, and both blocks may work similarly.
