Continuous L2 Paravertebral Block Versus Continuous Lumbar Plexus Block for Postoperative Analgesia

Completed · Not applicable

Conditions studied: Total Hip Arthroplasty

In brief

This prospective study is intended to compare the analgesic efficacy, preservation of lower extremity motor power and side-effect profile of L2 Paravertebral lumbar plexus approach compared to Posterior nerve stimulation guided lumbar plexus approach, continuous local anesthetic infusion postoperative analgesia of Total Hip Arthroplasty. The L2 Paravertebral technique of lumbar plexus block, as part of a multimodal pain treatment, could be a cost-effective alternative with a equal profile of analgesic efficacy and motor power sparing with greater promotion of early achievement of postoperative physical therapy goals.
