Comparación de la validez de la escala de Alarcón Pittaluga y Hadlock IV en la estimulación del peso neonatal Hospital Vicente Corral Moscoso, 2014

Abstract

Introduction: fetal growth is an important condition of obstetrics. Evaluate fetal weight and their alterations helps us take resolute behavior for the future newborn; therefore, with the support of ultrasound as Gold Standard and the application of different local growth curves are an ideal pillar in perinatology. Objective: to compare the validity of the scale between Alarcón Pittaluga and Hadlock IV for estimating the Neonatal weight in pregnant women attended at "Vicente Corral Moscoso" Hospital. Methods and techniques: a comparative analytical study of diagnostics was made in 524 pregnant in the Department of Gynecology and Obstetrics Hospital Vicente Corral Moscoso. They were made underwent biometry test according to the proposed techniques by Alarcón Pittaluga and Hadlock IV to estimate fetal weight by ultrasound compared with birth weight. Descriptive statistical analysis, mean difference, Pearson correlation index, ROC (Receiver Operating Characteristic) curve, sensitivity and specificity was performed. Results: pregnant mean age of the study population was 27 years, 38 weeks and parity 3 gestations. Alarcón Pittaluga weight was 2880 g, Hadlock was of 3126 g and newborn weight was of 3020 g. The mean difference was significant. Alarcón Pittaluga formula was sensitivity and specificity were 66,37% and 59,27% respectively compared to 66.37% and 81.51% of Hadlock. Conclusions: The Hadlock scale has better specificity, while both scales showed similar sensitivity, however Hadlock has greater diagnostic confidence. With this, our hypothesis is untested.
