Nerve block may cut opioid need after abdominal surgery

This study looked at whether adding a rectus sheath block (a type of nerve block) to general anesthesia can better control pain after a midline cut in the belly. 46 adults having abdominal surgery were randomly assigned to get either general anesthesia alone or with the block. Researchers measured pain levels, how soon patients needed extra pain medicine, and signs of inflammation. The goal was to see if the block could reduce pain and the need for opioids.
