Determinación de la línea de tuffier y sus factores asociados en pacientes programadas para cesárea bajo anestesia neuroaxial guiada por ultrasonografía. Hospital Vicente Corral Moscoso. Cuenca 2021

Abstract

Background: The Tuffier line is a reference used daily to guide lumbar puncture, however, it is not entirely reliable as it can be influenced by factors such as age, height, body mass index, pregnancy, among other factors. Objectives: Determine the location of the Tuffier line in patients undergoing cesarean section with neuraxial anesthesia and relate associated factors using ultrasound. Method: The present work is a cross-sectional analytical study, made up of 267 patients undergoing cesarean section under neuraxial anesthesia at the Vicente Corral Moscoso hospital in Cuenca Ecuador, between January and December 2021, the data was collected in a form, the program was used. SPSS version 22 and to analyze descriptive and inferential statistics. Results: Using ultrasound, 94% of the study population had a demarcation of Tuffier's line above L4. It was determined that height and body mass index are factors that influence, women with a height less than 1.52 meters had an association with the demarcation on L3 with the palpation method (OR 153.14 CI = 20.826 - 1126.099 p <0.001), body mass index greater than 25 kg/m2(OR 2.114 CI = 1.180 – 3.787 p = 0.001). Conclusions: The palpation method may not be reliable in pregnant women to determine the space for the application of neuraxial anesthesia, when determining by ultrasound the location above L4 was associated with a smaller height of the pregnant woman.
