Background: The transverse abdominis plane (TAP) block, a regional block provides effective analgesia after lower abdominal surgeries if used as part of multimodal analgesia. In this prospective, randomized double-blind study, we determined the efficacy of TAP block in patients undergoing cesarean section. Materials and Methods: Totally, 62 parturients undergoing cesarean section were randomized in a double-blind manner to receive either bilateral TAP block at the end of surgery with 20 ml of 0.25% bupivacaine or no TAP block, in addition to standard analgesic comprising 75 mg diclofenac 8 hourly and intravenous patient-controlled analgesia (PCA) tramadol. Each patient was assessed at 0, 4, 8, 12, 24, 36, and 48 h after surgery by an independent observer for pain at rest and on movement using numeric rating scale of 0-10, time of 1 st demand for tramadol, total consumption of PCA tramadol, satisfaction with pain management and side effects. Results: Use of tramadol was reduced in patients given TAP block by 50% compared to patients given no block during 48 h after surgery (P < 0.001). Pain scores were lower both on rest and activity at each time point for 24 h in study group (P < 0.001), time of first analgesia was significantly longer, satisfaction was higher, and side effects were less in study group compared to control group. Conclusion: Transverse abdominis plane block was effective in providing analgesia with a substantial reduction in tramadol use during 48 h after cesarean section when used as adjunctive to standard analgesia.
