Postoperative Analgesic Efficacy of Intraoperative Pectoral Nerve Block for Modified Radical Mastectomy: a...

Severe acute postoperative pain following breast surgery increases the risk of persistent pain and affects the recovery of patients. Recently, pectoral nerve (PECs) block has gained significance as a regional fascial block that can provide adequate postoperative analgesia. This study aimed to evaluate the safety and efficacy of PECs II block, which was given intraoperative under direct vision after performing modified radical mastectomy for breast cancer patients. This prospective randomised study was comprised of a PECs II group (n = 30) and a control group (n = 30). Group A patients received 25 ml of 0.25% bupivacaine for PECs II block intraoperatively after the surgical resection was done. Both groups were compared with respect to the demographic and clinical parameters, total intraoperative fentanyl dose, total duration of surgery, postoperative pain score (Numerical Rating Scale) and the analgesic requirement, postoperative complications, postoperative duration of hospital stay, and the outcome. Intraoperative PECs II block was not associated with any increase in the duration of surgery. The postoperative pain scores were significantly higher in the control group till 24 h after the surgery, and so was the postoperative analgesic requirement. Patients in the PECs group were found to have rapid recovery and decreased postoperative complications. Intraoperative PECs II block is not only safe, time-saving procedure but also significantly reduces the postoperative pain and analgesic requirement in breast cancer surgeries. It is also associated with a faster recovery, decreased postoperative complications, and better patient satisfaction.
