About this trial

This randomized, blinded, controlled clinical trial aims to evaluate the effectiveness of ultrasound-guided retrolaminar block in reducing postoperative opioid consumption in patients undergoing lumbar spine fusion surgery under multimodal analgesia.

The participants will:

* Be randomly assigned in a 1:1 ratio to receive either a retrolaminar block with 0.25% bupivacaine plus epinephrine or a sham block (normal saline) prior to surgical incision. * Receive standardized multimodal analgesia. * Have follow-up by the Acute Pain Unit during the first 3 days, to assess opioid consumption (morphine) in 24 hours, pain intensity measured by Numeric Rating Scale, quality of recovery assessed by the QoR-15 questionnaire, intraoperative blood loss, and postoperative complications.
