Abstract

We compared umbilical Doppler velocimetry with biophysical parameters, obstetrical management, and neonatal morbidity. The study of 85 pregnancies was prospective and blind both to the obstetric and pediatric staff. Our results show that under the same biophysical diagnosis, ie, abnormal fetal growth, oligohydramnios, and nonreactive cardiotocographics, the prevalence of neonatal morbidity was significantly higher in fetuses with associated abnormal umbilical pulsatility index (PI) in utero. Newborns with abnormal PI were delivered earlier, mostly for fetal indication, and were smaller and more asymmetrical than newborns with a normal PI in utero. The analysis of morbidity for homogeneous classes of weight showed that in the group of newborns between 1500 and 2500 g, newborns with normal umbilical PI did show only metabolic disturbances and one respiratory distress syndrome. On the contrary, newborns of the same gestational age and of the same weight with abnormal PI had more severe morbid episodes. In the class of weight between 1500 and 1000 g not only the severity but also the prevalence of neonatal morbidity was significantly higher in newborns with an abnormal PI in utero. None of the newborns delivered below 1000 g had a normal umbilical PI. Five died in the early neonatal period. Three suffered from mild neuromotor sequelae. Practical consequences of these findings on fetal management are the scheduled frequency of biophysical examinations, which must be closer and on an inpatient basis whenever abnormal, and the interpretation of other abnormal biophysical parameters, which must be considered as more severe whenever associated with an abnormal umbilical velocimetry.
