Lumbar spinal procedures are commonly associated with significant postoperative pain, which may impair early mobilization and increase opioid consumption. In routine clinical practice, QIPB is increasingly used as part of multimodal analgesia to improve pain control and reduce opioid-related adverse effects.\n\nAdult patients scheduled for elective lumbar spinal surgery under general anesthesia will be followed according to routine clinical care. Postoperative analgesia will be managed with intravenous patient-controlled analgesia (PCA) using tramadol, with or without the addition of ultrasound-guided QIPB, based on the preference of the attending anesthesiologist. No intervention or treatment assignment will be performed by the investigators.\n\nPostoperative pain scores at rest and during movement, opioid consumption, need for rescue analgesics, incidence of nausea and vomiting, and patient satisfaction will be recorded during the first 24 hours after surgery. The findings of this study are expected to provide further clinical evidence regarding the effectiveness of QIPB as part of multimodal analgesia in lumbar spinal surgery.",[74,75,76],"Postoperative Pain","Lumbar Spine Surgery","Postoperative Analgesia",[78,21,79,80,76,81],"Quadro-Iliac Plane Block","Ultrasound-Guided Regional Anesthesia","Lumbar Spinal Surgery","Patient-Controlled Analgesia","2026-02-19",{"date":84,"type":85},"2026-02-23","ACTUAL",{"date":87,"type":85},"2026-01-05",{"date":89,"type":70},"2026-10",{"name":5,"class":6},1]
