LPB Combined with QLB Using Single-needle Technique (LPQLB-SNT) for Hip Arthroplasty

Summary

Total hip arthroplasty (THA) is one of the most successful orthopedic procedures to effectively relieve pain and restore function in patients with hip osteoarthritis, osteonecrosis of femoral head and hip fracture.The Lumbar Plexus Block (LPB) is currently used as the standard regional anesthesia technique to provide postoperative pain management after THA. The lumbar plexus (LP) originates from T12 to L5. In general, multiple-needle nerve blockade procedure is needed to block different branches of LP. Therefore, we need more time to finish the regional anethesia procedure and it's not easy for an inexperienced anesthesiologist to master the technique absolutely. In addition, multiple injections will increase the discomfort of the patients. We aim to investigate the effects of lumbar plexus combined with quadratus lumborum block using single-needle technique with Shamrock method as an alternative regional anesthesia.
