Summary

This study compares two types of ultrasound-guided nerve blocks given before lumbar microdiscectomy (a type of back surgery) to see which one provides better pain relief. Eighty adults aged 18-65 will be randomly assigned to receive one of the two blocks. The main goal is to measure how much opioid pain medication they need in the 48 hours after surgery, with secondary goals including recovery quality, pain scores, and side effects.
