Erector Spinae Plane Block in Lumbar Release Surgery

"After installing the sleeping patient and identifying the surgical level by the surgeon, the anesthetist will perform the erector spinae plane block. The anesthetist performs an ultrasound to view the spine and erector muscles and identifies the transverse processes of the vertebra involved in the surgery. Once the location has been made, the anesthetist injects the anesthetic product under ultrasound control between the erector muscle of the spine and its anterior fascia, the trajectory of the needle being thus visualized throughout the procedure. The anesthetist bilaterally injects 3ml/kg of solution with a maximum of 30ml injected.~Drug : Levobupivacaïne 2,5mg/ml."
