Objective The brain sparing phenomenon in the fetus is a protective mechanism aimed at
maintaining sufficient blood flow towards the brain during chronic or acute fetal stress, such …

Objective: To investigate whether fetal blood circulation is influenced by the maternal supine
position. Methods: The inclusion criteria were good health, a singleton pregnancy, maternal …

Introduction: Recent studies have demonstrated an association between maternal supine
sleep position and an increased risk of late stillbirth. During late pregnancy, the gravid …

Objective: This study was undertaken to verify by means of Doppler ultrasonography and
simultaneous fetal pulse oximetry the redistribution of fetal blood flow in favor of the brain …

Cerebral hemodynamics were studied in eight nonpregnant women and 24 women in late
pregnancy by internal carotid artery velocimetry with a 3.5-MHz continuous-wave Doppler …

Key points Maternal supine sleep position in late pregnancy is associated with an increased
risk of stillbirth. Maternal supine position in late pregnancy reduces maternal cardiac output …

Objective To correlate the applied pressure during external cephalic version with the
changes in fetal middle cerebral arterial and umbilical arterial flow before and after the …

Objective To assess the distribution of fetal blood flow impedance of the umbilical and
middle cerebral artery in active uncomplicated labour and in labour complicated by variable …

About half of all fetuses with increased resistance to blood flow, but with still detectable
diastolic blood velocity in the umbilical artery (UA), show signs of imminent asphyxia during …

Background Studies on blood flow velocity in the fetal middle cerebral artery have revealed
signs of brain sparing in chronic hypoxia. These signs of brain sparing can disappear in the …
