RELIEVED Study: Regional Anesthesia Techniques for Pain Management in Pelvic and Acetabular Fractures - A Prospective Pilot Cohort Study

What this Trial Is About

This observational study evaluates the impact of Regional Anesthesia (RA) techniques supported by anatomical and scientific evidence on managing acute post-operative pain in patients with pelvic or acetabular fractures. The study aims to find out if RA can reduce opioid use in the first 24 hours after surgery, decrease pain scores within 48 hours, and lower the incidence of complications and persistent post-surgical pain. Participants receive either RA techniques combined with standard multimodal analgesia or multimodal analgesia alone according to current clinical practice. RA methods include Supra-inguinal fascia iliaca block, lumbar erector spinae plane block, and transmuscular quadratus lumborum block, all performed by experienced anesthesiologists using ultrasound guidance and long-acting anesthetics. In cases where trained anesthesiologists are unavailable, patients receive only standard multimodal analgesic treatment. During and after surgery, researchers will assess pain intensity at scheduled times, track opioid use and side effects, and monitor the potential development of chronic pain. Functional recovery will be followed up clinically at 30, 60, and 90 days post-surgery. The main outcome measured is opioid consumption within 24 hours after surgery, along with secondary measures such as pain scores, opioid and RA side effects, and hospital stay length.
