This article aims to identify the intervertebral localization by ultrasound of neuraxial blocks installed by palpation technique of anatomical references. To this end, a descriptive, cross-sectional, analytical observational study was conducted with 35 patients from the Hospital Sanatorio Durango between 18 and 60 years undergoing elective surgery with ASA I-III. After the elimination of the anesthetic residue, we performed ultrasonographic tracking. The analysis included frequencies, proportions, mean and SD, OR, and prevalence OR with 95% CI, T trend t χ2 and χ2 test (p < 0.05). Correspondence was 34.3%. Weight, height, BMI, BMI categories, position for blocking, and type of neuroaxial blockade did not have statistical significance (p > 0.05). In patients without correspondence, we found that 73.9% had cephalic localization. Using ultrasound, those without correspondence were L1-L2: 39.13%, L2-L3: 26.1%, L3-L4: 17.4%, two levels: 13.04 and T12-L4: 4.35%. For this sample, the accuracy of the identification of the intervertebral space by the technique is poor, so the use of ultrasound can improve the installation. This type of research is essential since the continuous enhancement of anesthetic techniques will improve the prognosis of operated patients.
