Serratus anterior plane block is an interfascial injection technique for analgesia of the chest wall. The aim of this study was to investigate the effect of magnesium and dexmedetomidine as adjuvant agents on postoperative analgesia in serratus anterior plane block in patients undergoing modified radical mastectomy.
