Quadro-Iliac Plane Block Versus Wound Infiltration for Postoperative Pain After Single-Level Lumbar Discectomy

This prospective observational study aims to compare the effects of the Quadro-Iliac Plane Block (QIPB) and wound infiltration (WI) on postoperative acute pain in adult patients undergoing elective single-level lumbar discectomy. QIPB is a newly introduced ultrasound-guided fascial plane block, and it is currently being used in routine clinical practice in our anesthesiology department as part of postoperative analgesia for lumbar spine surgery. Wound infiltration is a conventional method in which local anesthetic is injected into the surgical field at the end of the procedure. In this study, eligible patients will be monitored prospectively without randomization or alteration of standard care. Postoperative pain scores, opioid consumption, nausea and vomiting, patient satisfaction, and recovery parameters will be evaluated during the first 24 hours after surgery. The study aims to provide real-world clinical evidence comparing these two analgesic techniques in lumbar discectomy patients.
