Validación de la fórmula de cromi por ecografía fetal para diagnóstico de macrosomía en embarazos a término. Hospital Vicente Corral Moscoso. Octubre de 2020 a agosto de 2021

Abstract

Background: Fetal macrosomia is a frequent condition, it is related to a high rate of both maternal and fetal complications, therefore, it is important to have prediction methods during pregnancy and thus be able to adequately manage the maternal binomial. -fetal. Objectives: to determine the validity of the Cromi formula by ultrasound for the diagnosis of fetal macrosomia in term pregnancies. Hospital Vicente Corral Moscoso. October 2020 to August 2021. Methods: diagnostic validation test in women between 37 and 41.6 weeks of gestation. An ultrasound measurement of fetal anthropometry and umbilical cord area was performed, weighted values were calculated according to the Cromi, Hadlock and umbilical cord area formulas. Results: of 285 newborns, 1.4% were macrosomic, maternal age between 14 and 42 years, 50.53% multiparous, mean gestational age of 39.3 weeks. Hadlock, Cromi and the umbilical cord area demonstrated high specificity (greater than 96%) but poor sensitivity (between 25 and 50%), NPV greater than 98%, but low PPV (10- 50%) in the detection of fetal macrosomia. Conclusions: The study showed low sensitivity and PPV for Hadlock, Cromi and umbilical cord area percentile >95, however, the specificity and NPV values were high, although they were not shown to be superior in prediction. of fetal macrosomia, if it could be a useful tool when predicting its absence.
