Key result
Ultrasound-guided lumbar plexus block provided a higher satisfying analgesia rate than transversus abdominis plane block (87.5% vs 65%, P<0.05) in children undergoing hip dislocation surgery.
Why the study?
Lumbar plexus block is frequently used for adult hip surgery but rarely in pediatric patients, leaving its efficacy and feasibility compared to transversus abdominis plane block unclear in children.
Does ultrasound-guided lumbar plexus block improve postoperative analgesia compared to transversus abdominis plane block in children undergoing hip dislocation surgery?

Ultrasound-guided lumbar plexus block provides a longer and more satisfying postoperative analgesic effect than transversus abdominis plane block in children undergoing hip dislocation surgery.
Ultrasound-guided lumbar plexus block may provide longer analgesia than TAP block after pediatric hip surgery; extends scarce RCT data to children.
Lumbar plexus block is often used as analgesia for adult hip surgery, but it is rarely used in pediatric patients. This study aimed to compare the efficacy and feasibility of ultrasound-guided lumbar plexus block versus transversus abdominis plane block for postoperative analgesia in children with hip dislocation. Eighty children undergoing unilateral hip dislocation surgeries at our hospital from October 2019 to February 2021 were randomized to the lumbar plexus block group (group L) and transversus abdominis plane block group (group T). Compared with group L, the regional block time in group T was lower (8.0 ± 2.5 vs 11.5 ± 2.3 min,P< 0.05), and the ultrasound image definition was better (P< 0.05). There were no significant differences in mean blood pressure and heart rate within 24 h (allP> 0.05). Children’s Hospital of Eastern Ontario Pain Scale scores were lower in group L than in group T at 18–24 h only (allP< 0.05). The satisfying analgesia rate in group L was higher than in group T (87.5 vs 65%,P< 0.05). No regional block-related complications were found in both groups. Ultrasound-guided lumbar plexus block showed a longer postoperative analgesic effect in children with hip dislocation compared with transversus abdominis plane block.

Sun et al. (2022) conducted an RCT in hip dislocation (n=80). Ultrasound-guided lumbar plexus block vs. Transversus abdominis plane block was evaluated on Satisfying analgesia rate (p=<0.05). Ultrasound-guided lumbar plexus block provided a higher satisfying analgesia rate than transversus abdominis plane block (87.5% vs 65%, P<0.05) in children undergoing hip dislocation surgery.
