TL;DR: Fetal hemoglobin concentrations increased with increasing gestational age in the 265 normal fetuses, and the peak velocity of systolic blood flow in the middle cerebral artery was measured by Doppler velocimetry.
Journal ArticleDOI
Increase of fetal hematocrit decreases the middle cerebral artery peak systolic velocity in pregnancies complicated by rhesus alloimmunization.
TL;DR: The increase of fetal hematocrit significantly decreases the middle cerebral artery peak systolic velocity supporting data that this Doppler measurement may be useful for the diagnosis of fetal anemia.
Journal ArticleDOI
Can a single measurement of amniotic fluid delta optical density be safely used in the clinical management of Rhesus-alloimmunized pregnancies before 27 weeks' gestation?
TL;DR: These data confirm previous results that the diagnosis of fetal anemia in Rhesus-alloimmunized pregnancies before 27 weeks' gestation cannot be accurately made by a single measurement of amniotic fluid optical density at 450 nanometers.
Journal ArticleDOI
The effect of intravascular blood transfusion on the flow velocity waveform of the portal venous system of the anemic fetus
TL;DR: In this paper, a color-guided pulsed Doppler was used to obtain flow velocity waveforms from the fetal portal vein in 14 anemic fetuses that were transfused in utero for rhesus alloimmunization.
Journal ArticleDOI
Intrauterine intravascular transfusions in fetal erythroblastosis: the influence of net transfusion volume on fetal survival.
TL;DR: An upper transfusion limit at 20 ml/kg corresponding to approximately 20% of the feto‐placental blood volume is recommended, based on the tolerated volume load of an anemic fetus.
