Comparing Pain Relief of Mid-Transverse Process to Pleura Block and Morphine PCA in Adults with Idiopathic Scoliosis Undergoing Spinal Fusion Surgery

What this Trial Is About

Researchers are comparing the pain relief effects of a multiple mid-transverse process to pleura MTP block with patient-controlled analgesia PCA using morphine in adults with idiopathic scoliosis undergoing posterior spinal fusion surgery. The study addresses the challenges of managing postoperative pain and hospitalization length in this group. Regional anesthesia techniques like epidural analgesia and paravertebral blocks, enhanced by ultrasound guidance, have become important in multimodal pain management. The MTP block and erector spinae plane ESP block are newer methods being evaluated for postoperative pain control. Participants are randomly assigned to one of two groups. One group receives multiple MTP blocks after anesthesia induction. The other group uses intravenous PCA with morphine, starting with a loading dose before surgery ends, followed by patient-controlled doses with specified lockout intervals and background infusion rates. This randomized, double-blind trial compares these two pain management approaches during and after surgery. Throughout the study, researchers monitor pain levels 24 hours after surgery as the primary outcome. They also track intraoperative fentanyl use, timing of first rescue analgesia, total morphine use, blood pressure and heart rate every 15 minutes during surgery, patient satisfaction, and any complications within 24 hours postoperatively. The overall goal is to better understand and improve pain control strategies in scoliosis surgery patients.
