Volume Versus Concentration: a Prospective, Double Blind, Parallel Study to Compare the Clinical Effectiveness of Bilateral Quadratus Lumborum Blocks Using High Volume/Low Concentration or Low Volume/ High Concentration Local Anesthetic in Nephrectomies
The quadratus lumborum has since 2016 become standard of care for abdominal and retroperitoneal surgeries at UPMC-Shadyside Hospital, replacing paravertebral blocks, and as part of a broader multimodal analgesia institutional Enhanced Recovery After surgery protocol. Since the first description of this technique, several approaches to and anatomic targets within the quadratus lumborum plane have been described although their mechanism of action, spread, and relative clinical effectiveness remain areas of some debate. What is proposed here is to investigate the relative clinical effectiveness of the relationship high volume/low concentration of local anesthetic or low volume/ high concentration of local anesthetic.
