Erector Spinae Plane Block After Lumbar Spinal Stenosis Surgery

Study Overview
=================
Brief Summary
-----------------
Lumbar spinae stenosis surgery is a frequent intervention resulting in important postoperative pain. Management of this postoperative pain is thus important. Different pain management therapies exist. The erector spinae plane (ESP) block was described in 2016. It involves the injection of local anesthetics into the interfascial plane, deep to erector spinae muscle, allowing the blockade of the dorsal and ventral rami of the thoracic spinal nerves. It was initially proposed for analgesia of costal fractures, pulmonary lobectomy and thoracic vertebrae. The ESP block (ESPB) could probably be extended to a large number of surgical procedures. ESPB has so far not been investigated in lumbar spinae stenosis surgery.
