Effectiveness of Ultrasound Guided PECS Block on Opioid Consumption and Patient Satisfaction Through Adequate Pain Control Following Breast Cancer Surgery.

Breast cancer is the most common and leading cause of cancer deaths among females worldwide. Patients undergoing modified radical mastectomy (MRM) are associated with moderate to severe acute postoperative pain and shoulder mobility restriction. This study aims to determine the effectiveness of ultrasound-guided PECS block for reducing opioid consumption, providing adequate postoperative pain management and improving patient satisfaction following breast cancer surgery.
