Accuracy of fetal weight estimation with regard to clinical decision making in preterm birth at the limit of viability

Objective: To identify possible confounding factors that have a negative impact on the accuracy of fetal weight estimation (FWE) in very low gestational age infants and to determine the impact of the accuracy of FWE on neonatal outcome. Methods: In this retrospective study, we included 87 cases from 23 – 26 weeks of gestation at birth that were further divided into three groups (accurate, overestimated and underestimated birth weight). 12 factors that potentially influence the accuracy of FWE (gestational age, gender, use of antenatal corticosteroids, multiple pregnancy, presentation of fetus, location of placen…
