Comparison of Serratus Posterior Superior Intercostal Plane Block and Deep Serratus Anterior Plane Block After Video-Assisted Thoracoscopic Surgery

This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) and Deep Serratus Anterior Plane Block in patients undergoing Video-Assisted Thoracoscopic Surgery. The primary outcome is Visual Analog Scale (VAS) during 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 toxicity, vascular puncture, infection), Patient satisfaction assessed using a Likert scale, Quality of recovery assessed using the QoR-15 questionnaire.
