Abstract

Objective: This study aimed to assess the efficacy of intraoperative serratus anterior plane block in controlling postoperative pain in female patients undergoing modified radical mastectomy.

Background: Postoperative pain control poses a common challenge for patients undergoing modified radical mastectomy, often managed through opioid administration. However, muscle block techniques have gained traction to reduce opioid use. The serratus anterior plane block is a thoracic regional anesthetic technique that improves postoperative analgesia.

Patients and Methods: This prospective randomized study involved 50 breast cancer patients who underwent modified radical mastectomy. They were randomly divided into two equal groups: group A received intraoperative serratus anterior plane block, and group B served as the control. Primary outcome was postoperative visual analogue scale (VAS); secondary outcomes included opioid and paracetamol consumption, and postoperative complications.

Results: Group A exhibited significantly lower VAS values within the first 12 hours after surgery (P < 0.005), significantly delayed first postoperative analgesic dose, a significant decrease in total postoperative paracetamol and nalbuphine consumption, and a significant decrease in the incidence of postoperative nausea and vomiting compared to group B. Group A showed a non-significant decrease in respiratory depression and neurapraxia incidence and had a shorter hospital stay than group B.

Conclusion: Serratus anterior plane block is a safe and effective technique that provides substantial pain relief after breast surgery, reducing analgesic consumption, shortening hospital stays, and enhancing patient satisfaction.
