The Lumbosacral Erector Spinae Plane Block for Abdominal Hysterectomy: A Case Report.

After major abdominal surgery and open hysterectomy, postoperative pain management is often challenging. Various abdominal fascial and truncal blocks, including paravertebral, erector spinae plane, transversus abdominis plane, and quadratus lumborum blocks, have been evaluated for their efficacy. When used in a multimodal pain control strategy, after an open abdominal hysterectomy under spinal anesthesia, the novel sacral erector spinae plane block showed promising results in terms of safety, efficacy, and minimal invasiveness.
