A fetal blood
sample was obtained by cordocentesis and routine karyotyping and subtelomeric FISH analysis revealed normal results.
Edema will decrease the blood flow in the villous blood vessels and lead to ischemia of the villi and interfere with the transfer of oxygen and nutrients from the maternal blood to the fetal blood
. It also enhances more production of VEGF in the placental tissues (Duh & Aiello; Cohen et al.).
It is concluded that Cardiotocography can be used as good screening tool for fetal surveillance especially where fetal blood
sampling or fetal ECG are not available.
When fetal blood
reaches the placenta, this process is reversed and C[O.sub.2] diffuses across the placenta to the maternal circulation.
In our study it was a pure isolate from fetal blood
in two cases of AFIS.

The effects of regional anaesthesia for caesarean section on maternal and fetal blood
flow velocities measured by Doppler ultrasound.
Fetal DNA is found in mother's blood stream, cell-free fetal DNA enters into the blood stream through the placenta, placenta is a flattened organ in the uterus where maternal blood and fetal blood
. The fetal DNA can be split into very acute fragments, less than 200 base pairs on an average.
Its elevated maternal levels have previously been associated with clinical metrics of fetal blood
Maternal blood was obtained before C-section and fetal blood
was collected from the umbilical cord vein after birth.
We postulate that the MCA PSV was not raised because of the combination of hypoxia due to placental insufficiency and possibly episodes of hypovolaemia, superimposed on the effects of (sub)acute anaemia due to fetal blood
The editors have organized the contributions that make up the main body of the text in thirteen chapters devoted to fetal heart activity and measurements of labor activities, fetal blood
analysis, amniotic fluid interventions and examinations, and a wide variety of other related subjects.
