Summary
Brief summary (as posted)
This randomized controlled study aims to compare the analgesic efficacy of the ultrasound-guided modified pectoral nerve block (PECS II) and the midpoint transverse process to pleura (MTP) block in female patients undergoing modified radical mastectomy (MRM). Postoperative pain intensity will be assessed using the Visual Analog Scale (VAS) over the first 24 hours, with additional evaluation of opioid consumption and complications.
