Summary

This study compared two types of nerve blocks (TAP and QLB) to see which one better controls pain and reduces the need for strong painkillers after laparoscopic gallbladder removal. 65 adults having this surgery received one of the two blocks. The goal was to find a safer way to manage pain and avoid opioid side effects like nausea and drowsiness.
