Ultrasound-Guided Erector Spinae Plane Block for Postoperative Pain Control in Lumbar Spondylolisthesis Surgery

This clinical trial aims to evaluate the effectiveness of ultrasound-guided erector spinae plane (ESP) block as an adjunct to general anesthesia for managing postoperative pain in patients undergoing lumbar spondylolisthesis surgery. The study will compare two groups: one receiving general anesthesia with ESP block (intervention group) and the other receiving general anesthesia alone (control group). The primary objective is to assess postoperative pain relief, opioid consumption, and hemodynamic stability. Secondary outcomes include adverse events and recovery quality. This trial will provide valuable insights into the efficacy of ESP block in improving recovery outcomes and reducing opioid use in spine surgery patients.
