What this trial studies

This study investigates the effectiveness of adding magnesium sulfate to local anesthetics in combined Pectoralis Nerve Block II and stellate ganglion block for managing postoperative pain in patients undergoing modified radical mastectomy. The research aims to enhance pain relief by utilizing regional anesthesia techniques that target specific thoracic nerves and sympathetic ganglia. By incorporating magnesium sulfate, known for its analgesic and anti-inflammatory properties, the study seeks to improve the overall pain management strategy for these patients.

Who should consider this trial

Good fit: Ideal candidates include adult females scheduled for elective modified radical mastectomy with a BMI between 20 and 40.

Not a fit: Patients with bleeding disorders, chronic pain syndromes, or those with a history of substance abuse may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce postoperative pain and reliance on narcotics for patients after breast surgery.

How similar studies have performed: Previous studies have shown promising results with similar nerve block techniques, but the addition of magnesium sulfate in this specific context is relatively novel.
