TO COMPARE THE ANALGESIC EFFICACY OF 0.25% BUPIVACAINE AND 0.25% ROPIVACAINE IN TAP BLOCK AS A PART OF A MULTIMODAL ANALGESIA REGIMEN FOR POST CAESAREAN DELIVERY PAIN MANAGEMENT

Background: Women undergoing Cesarean delivery often face postoperative pain, which requires effective management to ensure their comfort and ability to care for their newborn. Transversus Abdominis Plane (TAP) block, a regional anesthetic technique, is increasingly used for postoperative analgesia in abdominal surgeries. This study aimed to evaluate the analgesic efcacy of 0.25% bupivacaine versus 0.25% ropivacaine in TAP blocks for pain relief following Cesarean delivery. Material And Methods: After approval from Indian Ethical Committee, this prospective, randomized, double-blinded, cross-sectional study was conducted at Sri Aurobindo Medical College and PG Institute, Indore, with 120 ASA grade I/II patients undergoing Cesarean section under spinal anesthesia. Patients were randomly assigned to receive TAP blocks with either 20 mL of 0.25% bupivacaine (Group B) or 0.25% ropivacaine (Group R). Postoperative pain intensity was measured using the Visual Analog Scale (VAS) at multiple time points (30 minutes, 2, 4, 6, 12, and 24 hours). Rescue analgesia, postoperative nausea and vomiting (PONV), and adverse effects were also monitored. Results: Patients in Group B experienced signicantly lower VAS scores at all time intervals compared to Group R (p < 0.05). The mean duration of analgesia and time to rst rescue analgesia were longer in Group B, suggesting superior pain relief with bupivacaine. The incidence of postoperative nausea was comparable between the two groups, with no cases of vomiting reported. Conclusion: 0.25% bupivacaine in TAP block provided superior postoperative analgesia compared to 0.25% ropivacaine, with longer-lasting pain relief and reduced need for rescue analgesia. TAP block is an effective and safe addition to multimodal postoperative pain management in Cesarean delivery.
