Quadratus Lumborum vs Erector Spinae Supplementary Blocks With Lumbar Plexus Blocks for Hip PAO

IRB-P00034474

This study proposes to evaluate the efficacy of single shot erector spinae block (ESB) versus single shot quadratus lumborum block (QLB) when used in conjunction with continuous lumbar plexus block (LPB) for postoperative analgesia in children and adolescents undergoing unilateral hip surgical procedures. The aim of this study is to compare the efficacy of the QL vs. ESP blocks as supplements to the lumbar plexus block with respect to pain control outcomes after hip PAO surgery. Both blocks are safe and easy to perform. There is currently no comparative, prospective data concerning the use of these two blocks for hip surgery. The investigational hypothesis is that there will be no clinical difference in the amount of opioid consumed or the overall pain control offered by these two block options.
