Liu HL, et al. - Given a wide use of ultrasound-guided transversus abdominis plane block (TAPB) in multimodal analgesia after cesarean delivery (CD), researchers here sought to describe the complications of TAPB during analgesia after CD. They performed random assignment of a total of 84 cases of CD to either a ropivacaine group (R group) or ropivacaine + dexamethasone group (RD group) in this double-blind trial. Record of the pain site and pain degree at rest and during activity at 2 h, 6 h, 10 h, 12 h, 14 h, 16 h, 20 h, and 24 h after maternal surgery was maintained. ISP developed in 19 patients, 14 in the R group and 5 in the RD group. Findings support the effectiveness of dexamethasone as an adjuvant for ropivacaine for reducing the ISP of ultrasound-guided TAPB after CD, and its possible value for enhancing the analgesic effect of ropivacaine.
