Sumario:BACKGROUND: This study was conducted to compare the analgesic efficacy of intrathecal fentanyl with ultrasound-guided transversus abdominis plane (TAP) block after lower segment cesarean section. The objectives of the study were to compare the effects of subarachnoid fentanyl versus TAP block with respect to duration of postoperative analgesia, time for first analgesic request, total analgesic consumption in 24 h, time to first breastfeed and Apgar score at 1 and 5 min. MATERIALS AND METHODS: Sixty-two patients undergoing elective or emergency cesarean delivery were recruited for the study in a prospective, randomized, single-blind manner. The patients were randomly allocated to either intrathecal fentanyl group (Group F) or TAP block group (Group T) after determining the eligibility criteria. Group F patients received subarachnoid block with 10 mg of 0.5% bupivacaine heavy with 25 mcg of fentanyl. Group T patients received subarachnoid block with 10 mg of 0.5% bupivacaine heavy prior to surgery and at the end of surgery, they received TAP block with 0.25% bupivacaine 20 mL on each side. RESULTS: Group T had significantly longer time for the first analgesic request (7.65 ± 1.23 h) than group F (4.10 ± 0.32 h). The total analgesic consumption in 24 h was significantly less in Group T (1.0 ± 0) than Group F (2.13 ± 0.34). The Visual Analogue Scale scores at rest and on movement were significantly less in Group T than Group F at all-time points. The Apgar score at 1 and 5 min and time to first breast feed were comparable between the two groups. The incidence of side effects was less in Group T. CONCLUSION: This study indicated that ultrasound-guided TAP block has a better analgesic as well as safety profile compared to intrathecal fentanyl for cesarean delivery.
