Erector Spinae Plane Block Versus External Oblique Intercostal Plane Block for Analgesia in Open Cholecystectomy
Sponsor: Sohag University
Summary
This randomized controlled trial aims to compare the analgesic efficacy of bilateral ultrasound-guided erector spinae plane block (ESPB) versus bilateral external oblique intercostal plane (EOI) block in patients undergoing open cholecystectomy. Patients will be randomly allocated into two groups to receive either ESPB or EOI block in addition to standard general anesthesia. The primary outcome is postoperative pain score assessed using the Numerical Rating Scale (NRS) at 2 hours after surgery. Secondary outcomes include intraoperative opioid consumption, postoperative nalbuphine requirements, time to first analgesic request, and hemodynamic changes. This study seeks to determine the more effective regional anesthesia technique for improving perioperative analgesia in open cholecystectomy.

Interventions
Erector Spinae Plane Block
Bilateral erector spinae plane block will be performed under ultrasound guidance using local anesthetic prior to surgical incision to provide postoperative analgesia.
External Oblique Intercostal Plane Block
Bilateral external oblique intercostal plane block will be performed under ultrasound guidance using local anesthetic prior to surgical incision to provide postoperative analgesia.
