Evaluation of 0.25% Bupivacaine vs. 0.375% Ropivacaine for Postoperative Analgesia using Transversus Abdominis Plane Block for Caesarean Section: A Comparative Study

Dr. G. Udayarani | Dr. P. S. Arunalatha

Abstract: Background: Pain after Caesarean section is described as moderate to severe by most patients. Transversus Abdominis Plane (TAP) block has a definite role in multimodal analgesia in lower abdominal surgeries. Hence this study was undertaken to compare 0.25% Bupivacaine with 0.375% Ropivacaine for postoperative analgesia using TAP block in caesareans ection. Methods: Forty patients were randomized into Group B (n=20) and Group R (n =20). TAP block was administered after completion of surgery using conventional landmark technique with 15mL of 0.25% Bupivacaine in Group B and 15mL of0.375% Ropivacaine in Group R on each side of the abdomen. Time to requirement of first analgesic dosage was observed in both the groups. Total analgesic requirement in the first 24 h, visual analogue scale (VAS) scores at 2, 4, 6, 8, 12 and 24h patient satisfaction and complications were also noted. Results: Mean time for the first dose of rescue analgesia after completion of surgery was 298.2?93.6 min in Group B and 447.6?85.2 min in Group R (P=0.0001). Total requirement of Diclofenac Sodium injection was 162.86?46.88mg in Group B whereas it was only 130.71? 44.49 mg in Group R (P=0.003). VASat 4, 6 and 8 h after surgery were significantly lower in the Ropivacaine group. Conclusion: 0.375% Ropivacaine provided longer duration of analgesia and resulted in lesser analgesic requirement than 0.25% Bupivacaine when used in TAP block after caesarean section.
