Summary

This study tested two types of nerve blocks—erector spinae plane block and thoracic paravertebral block—to see which one provides better pain relief after laparoscopic sleeve gastrectomy. Thirty adults having weight-loss surgery received one of the two blocks, and researchers measured how long it took before they needed extra pain medicine and how much pain they felt. The goal was to find the best way to control pain and help patients recover faster.
