Ultrasound-Guided Retrolaminar Block Plus Standard Multimodal Pain Relief for Lumbar Spine Surgery A Randomized Study

What this Trial Is About

Researchers are evaluating the effectiveness of ultrasound-guided retrolaminar nerve blocks added to standard multimodal pain management for patients undergoing lumbar spine surgery. This randomized controlled trial aims to reduce postoperative opioid use and improve pain control after surgery. The study includes adult patients scheduled for elective lumbar spine surgery with instrumentation and assesses various outcomes related to pain and recovery. Participants are randomly assigned to one of two groups one group receives bilateral ultrasound-guided retrolaminar blocks with Bupivacaine and Epinephrine before surgery along with standard multimodal analgesia, while the other group receives only the standard multimodal analgesia without the regional block. Standard anesthesia medications include Propofol, Remifentanil, and Rocuronium. The retrolaminar block is performed by an experienced anesthesiologist using ultrasound guidance. During the study, researchers will monitor total opioid use in the first 24 hours after surgery, pain intensity at multiple time points up to 72 hours, time to first rescue analgesia, sensory block duration, and incidence of nausea or vomiting. Other assessments include hospital length of stay, patient satisfaction, sleep quality, time to ambulation, and chronic pain development up to 6 months. Participation involves use of a patient-controlled analgesia device and follow-up visits to evaluate recovery and long-term pain outcomes.
