About

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.

80 participants in 2 patient groups

Erector Spinae plane Block (ESPB) group

Experimental group

Description:

The ultrasound-guided ESPB was realized at T12 level (levo bupivacaine 0.25% + epinephrine 1:200.000 4mg.kg-1 body weight)after the induction of anesthesia but before the start of the surgery.

Treatment:

Procedure: ESPB
