Summary
Brief summary (as posted)
This randomized double-blind controlled clinical trial was conducted to compare the analgesic efficacy of ultrasound-guided Pectoral Nerve Block versus Serratus Anterior Plane Block in female patients undergoing Modified Radical Mastectomy. Sixty-four ASA I-II female patients aged 35-60 years were randomly allocated into two equal groups: Group I received PEC I block and Group II received SAPB, using 20 ml of 0.25% bupivacaine in both groups after induction of general anesthesia. Postoperative pain was assessed using the Numeric Rating Scale (NRS) for 24 hours. Hemodynamic parameters, time to first rescue analgesia, total postoperative opioid consumption, and side effects were recorded. The SAPB group showed significantly lower postoperative pain scores during the first 6 hours, significantly longer time to first rescue analgesia, and significantly lower total pethidine consumption compared to the PEC I group. In addition, mean arterial blood pressure and heart rate were significantly lower intraoperatively and during early postoperative periods in the SAPB group. The incidence of postoperative nausea and vomiting was significantly higher in the PEC I group. Conclusion: Ultrasound-guided Serratus Anterior Plane Block provides superior postoperative analgesia with better hemodynamic stability and fewer opioid-related side effects compared to Pectoral Nerve Block in patients undergoing Modified Radical Mastectomy modified radical mastectomy
