ObjectiveSingle shot transversus abdominis plane (TAP) block and continuous local anesthetic infiltration wound catheter (CLAIWC) decreased the morphine consumption after caesarean section. The aim of this study was to compare the analgesic efficacy of CLAIWC and ultrasound-guided TAP block.MethodSixty patients undergoing caesarean section were prospectively randomized. After the caesarean section, the postoperative analgesia was randomized to either a CLAIWC localized below the fascia with an elastomeric pump for 48hours or a bilateral ultrasound-guided TAP block with injection of ropivacaine. Every patient had a morphine pump patient-controlled analgesia. The primary outcome was the morphine consumption during the first 48hours. Secondary outcomes were pain score levels, adverse effects of opioids, and patient satisfaction. Variables were collected during 48hours after the caesarean section.ResultsMedian cumulative 48-hour morphine consumption was 17 [8-51] mg in the TAP group versus 21 [7-34] mg in the CLAIWC group (P=0.3). We did not find a difference between the groups regarding pain, side effects and satisfaction scores.ConclusionAs part of a multimodal analgesic regimen, there is no significant difference between the TAP block and CLAIWC for postoperative analgesia after a caesarean section.Copyright © 2016 Société française d'anesthésie et de réanimation (Sfar).
