P108The importance of studying the ductus venosus for predicting acidosis at birth in pregnancies with absent or reversed end‐diastolic (ARED) velocity flow in the umbilical arteries

Abstract

BackgroundA study of the relation between methods for assessment of fetal well‐being and birth weight.MethodsA prospective study was conducted to assess the fetal well‐being in 61 singleton pregnancies with ARED. The results of these methods were compared with the occurrence of umbilical artery pH at birth < 7.20 and < 7.15. All data were analyzed and compared using logistic regression.ConclusionThe pulsatility index for veins in the ductus venosus is the most important predictor for acidosis at birth. Once the ductus venosus pi is known, it is possible to estimate the probability of fetal acidosis in pregnancies with AREDV.
