Trial Evaluating the Analgesic Efficacy of Magnesium Sulfate as an Adjuvant to Bupivacaine in Local Wound Infiltration for Patients Undergoing Modified Radical Mastectomy (MRM) With Axillary Clearance
Sponsor: King Hussein Cancer Center
Summary
This is a double-blind, randomized, controlled clinical trial evaluating the analgesic efficacy and safety of magnesium sulfate as an adjuvant to bupivacaine for local wound infiltration in patients undergoing modified radical mastectomy with axillary clearance. Participants will be randomized to receive either magnesium sulfate 750 mg with bupivacaine or the control intervention. Postoperative pain, analgesic requirements, and safety outcomes will be assessed during the postoperative period, including a follow-up safety assessment between Day 7 and Day 14 after surgery.

Interventions
Magnesium Sulfate 750 mg with Bupivacaine 0.5% for Local Wound Infiltration
Magnesium sulfate 750 mg added to 0.5% bupivacaine for a single intraoperative local wound infiltration following modified radical mastectomy with axillary clearance.
Bupivacaine 0.5% + Normal Saline
A single intraoperative local wound infiltration of 0.5% bupivacaine combined with normal saline following modified radical mastectomy with axillary clearance. The planned bupivacaine dose is 100 mg (20 mL), subject to reduction if it exceeds the participant-specific maximum allowable dose based on body weight.
