Comparison of the Efficacy of Ultrasound Guided Serratus Anterior Plane Block Versus Erector Spinae Plane Block for Postoperative Analgesia After Modified Radical Mastectomy: A Randomised Controlled Trial

Abstract

Objective: Several interfascial interfacial plane blocks have been described in patients undergoing modified radical mastectomy. We conducted this study to evaluate the analgesic efficacy of ultrasound-guided serratus anterior plane block and erector spinae plane block in patients undergoing modified radical mastectomy.
