Comparison of Serratus Posterior Superior Intercostal Plane Block and Rhomboid Intercostal Block for Postoperative Analgesia Following Breast Cancer Surgery With Axillary Lymph Node Dissection: A Randomized Controlled Trial
Sponsor: Antalya City Hospital
Summary
This randomized clinical trial aims to evaluate and compare the analgesic efficacy of the Serratus Posterior Superior Intercostal Plane (SPSIP) and Rhomboid Intercostal Block in patients undergoing Breast Cancer Surgery With Axillary Lymph Node Dissection. 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.
