Observing the Impact of Ultrasound-Guided Quadro-Iliac Plane Block on Pain Relief After Elective Lumbar Spine Surgery

What this Trial Is About

Researchers are evaluating how an ultrasound-guided Quadro-Iliac Plane Block QIPB affects pain relief after lumbar spinal surgery. This observational study focuses on adults aged 18 to 65 undergoing elective lumbar spinal surgery under general anesthesia. The goal is to see if QIPB improves pain control, reduces opioid use, and lowers side effects like nausea, helping patients recover more comfortably. Participants receive standard general anesthesia and postoperative intravenous patient-controlled analgesia PCA with tramadol. Some patients also receive the QIPB nerve block at the end of surgery, performed bilaterally using ultrasound guidance, while others receive local anesthetic infiltration LAI by the surgeon at the incision site. No treatments are assigned by the researchers instead, patients are observed in two groups based on their routine clinical care. Participants will be monitored in the post-anesthesia care unit and at 1, 6, 12, and 24 hours after surgery. Pain levels at rest and during movement will be recorded using a Numeric Rating Scale NRS. Researchers will also track opioid use, rescue pain medication needs, nausea and vomiting, sedation levels, patient satisfaction, and any block-related complications during the first 24 hours. This data aims to provide real-world evidence on QIPBs role in postoperative pain management.
