Median [1st; 3rd interquartile range] of total distribution, cranial, and caudal progression in absolute number of vertebrae, after 0.25% bupivacaine and iohexol administered via lumbar epidural between L1 and L2 under fluoroscopic guidance obtained in the anatomical study performed on dogs submitted to ovariohysterectomy (G0.25; n = 10) and canine cadavers (GC; n = 10).
