Comparison of bilateral ilioinguinal/iliohypogastric nerve block versus transverses abdominis plane block for postoperative pain relief for parturient undergoing caesarean section under spinal anaesthesia

Abstract

Introduction: Caesarean section is one of the common lower abdominal surgeries in young females with significant postoperative pain. Caesarean delivery and subsequent manipulation performed through Pfannenstiel incision are associated commonly with a significant degree of pain in the postoperative period.Aim: This study aims to compare TAP block versus II/IH block for post-caesarean delivery analgesia.Materials and Method: Study was conducted with 56 Pregnant women aged between 18-35yr scheduled for caesarean section under spinal anaesthesia were randomized to either TAP block (Inj. Bupivacaine plain 0.25%20cc bilateral) or II/IH block (Inj. Bupivacaine plain 0.25%20cc bilateral) given for postoperative pain management at the end of surgery. Pain score, Total tramadol consumption, time to first analgesic request was assessed during the first 48 h postoperatively.Result: The cumulative median tramadol consumption over 48 h were 16.96+/-32.66mg for TAP group and 56.25+/-567.98mg for II/IH. Pain score was statistically significantly lower in group TAP compared to group IIIH at 8hr, 12hr, 24hr and 48hrs (p=<0.05). Time for first request for rescue analgesia was also prolonged in the TAP block compared to IIIH block.Conclusion: TAP block was superior over IIIH block for post caesarean delivery pain management via Pfannenstiel incision.
