Comparative Analysis of Epidural Fentanyl and Conventional Analgesia in Single-Level Fenestration Lumbar Discectomy: A Randomized Controlled Study.

Abstract

Background: Lumbar disc prolapse is a common cause of back pain, frequently requiring 
surgery. Post-operative pain following single-level fenestration lumbar discectomy can be 
moderate to severe, lasting up to 72 hours. This study aimed to evaluate the efficacy of intra
operative epidural fentanyl infiltration for post-surgical analgesia.
