Ciobanu A, et al. - Researchers performed a prospective study including 21,989 singleton pregnancies that had undergone routine ultrasound examination at 31⁺⁰ - 33⁺⁶ weeks’ gestation and 45,847 that had undergone routine ultrasound examination at 35⁺⁰ - 36⁺⁶ weeks’ gestation to examine and compare the performance of routine ultrasonographic estimated fetal weight (EFW) and fetal abdominal circumference (AC) at 31⁺⁰ - 33⁺⁶ and 35⁺⁰ - 36⁺⁶ weeks’ gestation in predicting small for gestational age (SGA) neonates. As per findings, SGA neonates could be more accurately predicted by routine ultrasonographic examination during the third trimester if the scan is carried out at 35⁺⁰ - 36⁺⁶ weeks’ gestation than at 31⁺⁰ - 33⁺⁶ weeks. More accurate prediction was made assessing EFW than fetal AC and birthweight <3rd than <10th percentile. In addition, the prediction was more accurate if delivery occurs within two weeks than at any stage after assessment. Findings support using EFW <40th percentile as prediction of SGA neonates by EFW <10th percentile was modest and more than >85% of cases were predicted at 35⁺⁰ - 36⁺⁶ weeks’ gestation.
