Comparative Study between the Effect of Ultrasound Guided Pectoral Nerve Block (PEC 1) versus Serratus Anterior Plane Block (SAPB) For Postoperative Analgesia in Modified Radical Mastectomy

Abstract Background Breast cancer has continued to be the most common cancer afflicting women, accounting for 31% of all new cancer cases in the female population. Every year, thousands of patients undergo surgery in the region of the breast and axilla. Surgery is one of the mainstays of treatment, and a procedure called modified radical mastectomy (MRM) is now a standard surgical treatment for earlystage breast cancers. Objectives The aim of this work is to evaluate the Effectiveness of Ultrasound Guided Pectoral nerve block (PEC1) versus Serratus Anterior plane block (SAPB) for postoperative Analgesia in Modified Radical Mastectomy Patients and Methods After obtaining approval from the medical ethical committee in Ain Shams University This study was conducted in the operating theatres of Ain Shams University Hospitals. It included Thirty Female patients undergoing Modified Radical Mastectomy were divided randomly into two groups, each group consisted of 15 patients group I in which patients received PEC 1 and group II in which patients received Serratus Anterior Plane Block (SAPB). Results The two groups were adequately monitored and assessed post-operatively and they were compared regarding analgesic outcome by using the visual analogue scaling system, besides, recording time for first for analgesic need and total consumption of opioid and analgesic in the 1st 24 postoperative hours. Demographic data and post operative hemodynamics were also assessed. Conclusion SAPB was effective in reducing postoperative pain scores for 6 -12 hours and lower total 24-h postoperative opioid and analgesic consumption after Modified Radical Mastectomy under general anesthesia, compared to PEC 1 block.
