VP36.14: Antenatal predictors of adverse outcome related to hypoxia among small‐for‐gestational‐age fetuses diagnosed after 32 weeks of gestation

Abstract

The aim of this study is to describe the perinatal outcomes associated to FGR in a portuguese tertiary referral unit and to compare two consecutively implemented protocols (before and after February 2019). Methods: Retrospective study of singleton pregnancies diagnosed with FGR who delivered between 2018 and 2019 in Santa Maria Hospital. In our department, before February 2019, the delivery of a growth restricted fetus was programd for 37 weeks and it was anticipated if the pulsatility index of the ductus venosus (DV) was >95th centile from 28 weeks or if the umbilical artery end diastolic flow (UAEDF) was inverted from 32 or absent from 34 weeks. After February 2019, the delivery is anticipated if the A wave of the DV is absent or inverted from 26 weeks or if the UAEDF is reversed from 32 or absent from 34 weeks. We evaluated and compared obstetric and neonatal outcomes.
