Determinación de la localización anatómica de línea de Tuffier mediante ultrasonografía en pacientes sometidos a bloqueo neuroaxial en posición decúbito lateral. Hospital Vicente Corral Moscoso. Cuenca 2021.

Abstract

The Tuffier line for anesthesiologists is the reference point in neuroaxial anesthesia, not being a reliable data due to common variations that occur in its position. Objectives: To determine the exact anatomical location of Tuffier's line through ultrasonography in patients operated under neuraxial anesthesia in lateral decubitusat Hospital Vicente Corral Moscoso. Method: The present work is a cross-sectional analytical study, the sample was 334patients undergoing scheduled surgery under neuraxial anesthesia at the Vicente Corral Moscoso hospital, a form was designed and collected sociodemographic, clinical data and the location of the Tuffier Line. To determine the degree ofassociation, the PR and its 95% confidence interval were obtained. To determine statistical significance, the p value was obtained by chisquare, considering a p value < 0.05 statistically significant. Results: 334 patients were included, with a proportion of demarcation with Tuffier'sline above L4 in 41.3% of patients. In individuals aged 65 or over, an association was found with a location on L4 (p value = 0.006; PR 1.61; 95% CI = 1.20 - 2.14). There were no significant differences for sex, weight, height and nutritional status. Conclusions: Palpation as a single method is imprecise for the location of Tuffier's line, it must be confirmed by ultrasonography to avoid damage to the neuroeje.
