Abstract:
This case report presents the successful use of the continuous sacral erector spinae plane (ESP) block in 2 patients who underwent open hysterectomy under spinal anesthesia and benefited from prolonged postoperative analgesia without motor block or side effects. Postoperatively, a magnetic resonance imaging study was conducted, highlighting the anterior and cranial spread of the local anesthetic after continuous infusion from a sacral ESP catheter, contributing to a better understanding of the mechanism of action of the sacral ESP block.
