Objetivo: Establecer la correlación entre el diámetro del cordón umbilical y el área de los vasos umbilicales con el peso del recién nacido, en un grupo de gestantes sanas, a término, que acudieron a control en los Servicios de Prenatal, Sala de partos y unidad de ecografía de la Maternidad Concepción Palacios, entre mayo y diciembre de 2020. Métodos: Estudio prospectivo, descriptivo, correlacional y transversal, que incluyó 60 gestantes sanas, a término, con feto único y evolución normal del embarazo. Mediante ultrasonido abdominal se midió el diámetro del cordón umbilical y el área de los vasos umbilicales y se correlacionaron con el peso de los recién nacidos. La correlación entre las variables se realizó con F de Snedecor, de la tabla de análisis de la varianza. Se consideró una significancia del 95 % (p ˂0,05). Resultados: El diámetro medio del cordón umbilical fue 16,9 ± 2,3 mm, el área media de las arterias umbilicales fue 21,2 ± 5,2 mm2 y la de la vena umbilical fue 50,5 ± 12,9 mm2. No hubo relación entre el peso al nacer y el diámetro del cordón umbilical (p =0,868), el área de las arterias umbilicales (p =0,096), ni de la vena umbilical. Tanto el diámetro del cordón umbilical como el área de los vasos umbilicales fueron independientes de la edad materna, la paridad y la edad de gestación. Conclusiones: En este grupo de pacientes no se encontró correlación entre el diámetro del cordón umbilical y el área de los vasos umbilicales, con el peso del recién nacido.
Objective: To establish the correlation between the diameter of the umbilical cord and the area of the umbilical vessels with the weight of the newborn, in a group of healthy, full-term pregnant women who attended control in the Prenatal Service, Delivery Room and ultrasound of the Maternidad Concepción Palacios Hospital; between May and December 2020. Methods: Prospective, descriptive, correlational and cross-sectional study, which included 60 healthy pregnant women, at term, with a single fetus and normal evolution of pregnancy. Abdominal ultrasound measured the diameter of the umbilical cord and the area of the umbilical vessels and correlated with the weight of the newborns. The correlation between the variables was performed with Snedecor’s F, from the analysis of variance table. It was considered a significance of 95% (p ˂0.05). Results: The mean diameter of the umbilical cord was 16.9 ± 2.3 mm, the mean area of the umbilical arteries was 21.2 ± 5.2 mm2 and of the umbilical vein was 50.5 ± 12.9 mm2 . There was no relationship between birth weight and umbilical cord diameter (p= 0.868), umbilical artery area (p= 0.096), or umbilical vein. Both the diameter of the umbilical cord and the area of the umbilical vessels were independent of maternal age, parity and gestational age. Conclusions: In this group of patients, no correlation was found between the diameter of the umbilical cord and the area of the umbilical vessels with the weight of the newborn.
