Summary

This study looked at whether adding a nerve block (called ESP block) to general anesthesia helps people undergoing lower back surgery. 50 adults were split into two groups: one got the nerve block plus anesthesia, the other got anesthesia alone. The goal was to see if the nerve block reduces pain and the amount of painkillers needed during and after surgery.
