Serratus Posterior Superior Intercostal Plane Block for Postoperative Analgesia in Mastectomy
Mastectomy and Axillary Dissection: Evaluation of the Effect of Serratus Posterior Superior Intercostal Plane Block on Postoperative Analgesia: A Multicenter, Randomized, Placebo-Controlled Trial
연구 개요
상세 설명
This study is a prospective, randomized, placebo-controlled, multicenter clinical trial designed to evaluate the analgesic efficacy of the serratus posterior superior intercostal plane (SPSIP) block in patients undergoing mastectomy with axillary lymph node dissection. Postoperative pain following breast surgery is often significant and may increase opioid consumption and related adverse effects, highlighting the need for effective regional anesthesia techniques.
The SPSIP block is a novel ultrasound-guided interfascial plane block with emerging evidence in thoracic and chest wall procedures; however, its role in breast surgery remains unclear, particularly in placebo-controlled settings. This study aims to determine whether the SPSIP block provides additional benefit as part of a standardized multimodal analgesia approach.
Participants will be randomly assigned to receive either SPSIP block with local anesthetic or a placebo intervention under identical conditions, with blinding applied to all relevant parties. All patients will receive the same perioperative anesthesia and analgesia protocol.
The results of this study are expected to clarify the clinical value of SPSIP block in breast surgery and contribute to the development of evidence-based postoperative pain management strategies.
