Epidural Versus Quadratus Lamborum Block in Adult Open Nephrectomies

Our primary objective is to compare the effectiveness of bilateral QLB and epidural analgesia for postoperative management using VAS measured in PACU until 24 hours after surgery in patients undergoing elective open nephrectomies under GA. The secondary outcomes include: The 1st time to rescue analgesia and total amount of opioid consumption throughout the first postoperative day. hemodynamic variables. Any complications as postoperative nausea and vomiting (PONV) and sedation.
