ERECTOR SPINE PLANE BLOCK VERSUS LOCAL INFILTRATION ANAESTHESIA FOR TRANSFORAMINAL PERCUTANEOUS ENDOSCOPIC DISCECTOMY

In prone position, before the skin incision, patients in G1 underwent local infiltrative anaesthesia et the level of incision. The skin, subcutaneous tissue and muscles up to the foramen intervertebral were anesthetized by the surgeon employing forty millilitre solution of Lidocaine 1% with Dexamethasone 0.02% and Epinephrine 0.00018%.
