Background: Pain management after a caesarean section (CS) remains a significant clinical challenge, and alternative strategies for analgesia are continually being explored This study aimed to determine the efficacy of injecting the local anesthetic, Bupivacaine, bilaterally into the rectus sheath incision angles to block the ilioinguinal and iliohypogastric nerves, with the aim of reducing postoperative pain in patients undergoing CS under general anesthesia. Methods: A total of 150 female patients scheduled for elective Caesarean section were enrolled in this study. Patients were randomly assigned to one of two groups: Group A received Bupivacaine injections, while Group B received saline injections into the rectus sheath incision angles. Pain assessments, medication usage, and patient satisfaction were evaluated as primary outcome measures. Results: The study revealed that patients in Group A, receiving Bupivacaine injections, experienced significantly lower pain scores at various time intervals, shorter time to the first analgesic request, and a reduced need for meperidine compared to Group B. Additionally, patients in Group A reported higher satisfaction with pain management. Conclusion: Injection of Bupivacaine into both angles of the rectus sheath incision during Caesarean section effectively reduces postoperative pain and improves patient satisfaction.
