SPSIP vs ESP Block for Analgesia After Rib Fracture Surgery

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) block and the Erector Spinae Plane (ESP) block in patients undergoing surgical stabilization of rib fractures. The primary outcome is the Visual Analog Scale (VAS) score within the first 24 hours after surgery. Secondary outcomes include total opioid consumption, requirement for rescue analgesia, block performance time, block-related and systemic side effects (hematoma, pneumothorax, local anesthetic systemic toxicity, vascular puncture, and infection), patient satisfaction assessed using a Likert scale, and quality of recovery assessed using the QoR-15 questionnaire.
