Staker JJ, et al. - The effectiveness of a new ilioinguinal-transversus abdominis plane block as a component of multimodal analgesia for elective caesarean section was assessed. In women, who randomly received the ilioinguinal-transversus abdominis plane block or a sham block at the end of surgery, the cumulative mean (95%CI) fentanyl dose at 24 h was noted to be 71.9 (55.6–92.7) μg in the ilioinguinal-transversus abdominis group vs 179.1 (138.5–231.4) μg in the control group. In post-hoc analysis, the ilioinguinal-transversus abdominis group vs the control group was less likely to use ≥ 1000 μg fentanyl. In terms of opioid-related side-effects or maternal satisfaction with analgesia, no differences were seen. Overall, when used as a component of usual multimodal analgesic regimen, the ilioinguinal-transversus abdominis plane block offered superior analgesia.
