Objective. To determine the usefulness of the mean pulsatility index (PI) of uterine artery doppler before 30 gestation weeks’ as a predictor of macrosomia in newborns treated at the National Perinatal Maternal Institute during the period 2011- 2012. Material and methods. A retrospective, cross-sectional and analytical study. It was determined the mean pulsatility index of the uterine arteries to 232 pregnant women under 30 gestation weeks’ and birth weight was calculated according to birth gestational age for two groups, the first with infants with appropriate birth weight and the second with macrosomic neonates (n = 18/ 7,8%), which were compared using standard deviations, Pearson correlation, Student t test and receiver-operator curve (ROC). Results. Variation was found between the two groups in the four mean indices (peak systolic, peak diastolic, pulsatility index and resistance...
