ESP vs Subcostal TAP Block for Analgesia After Laparoscopic Cholecystectomy

This prospective, randomized, double-blind study compares the analgesic efficacy of ultrasound-guided erector spinae plane (ESP) block and subcostal transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy. The primary outcome is 24-hour postoperative opioid consumption. Secondary outcomes include postoperative pain scores, time to first analgesic request, shoulder pain, postoperative nausea and vomiting, and block-related complications.
