Anterior Quadratus Lumborum Block Versus Erector Spina Plane Block in Percutaneous Nephrolithotomy Surgery

"Patients who applied the QLB3 block before PCNL surgery were included in this group~Multimodal analgesia protocol is applied to all patients undergoing PCNL surgery in our clinic. According to this protocol, patients are administered iv tenoxicam 20mg after induction of general anesthesia and iv paracetamol 1 gr intraoperatively. Postoperative analgesia: iv paracetamol 1gr every 8 hours and iv PCA of 0,2mg/ml morphine (the bolus dose is 20 mcg/kg, the lock-in time of 6-10 minutes, and the 4-hour limit is adjusted to be 80% of the calculated total dose). In cases where rescue analgesia is required (VAS score ≥4), 100 mg tramadol is administered to patients. The prophylaxis for postoperative nausea and vomiting (PONV) involved the routine administration of 8 mg IV dexamethasone to patients before induction and 0.15 mg/kg IV ondansetron 20 minutes before the end of the procedure."
