Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are female patients aged 35 to 65 who are scheduled for modified radical mastectomy.
✕Probably not a fit
Patients who have contraindications for local anesthetic use or those with significant comorbidities may not benefit from this study.

What this trial studies
This study aims to evaluate the effectiveness of two different ultrasound-guided nerve blocks—pectoral nerve block and mid-point transverse process block—in providing postoperative analgesia for women undergoing modified radical mastectomy. Patients will undergo a thorough preoperative assessment, including medical history and laboratory tests, before being randomly assigned to one of the two nerve block techniques. The procedure will be performed by an experienced anesthesiologist under sterile conditions after the induction of general anesthesia. Pain levels will be monitored using a numeric rating scale to assess the effectiveness of each technique.
Why it matters
Potential benefit: If successful, this study could lead to improved pain management strategies for patients undergoing breast surgery.
How similar studies have gone: Previous studies have shown varying success with nerve blocks for postoperative pain management, making this approach both relevant and potentially beneficial.
