At the 24th week of gestation, a fetal blood
sample was obtained by fetal cord blood sampling.
Additionally, the peripheral thick-walled vessels showed the same thick placental barrier leading to decreased oxygen and nutrient transfer from the mother to the fetus, due to the increased distance between the maternal blood in the intervillous spaces and the fetal blood
in the blood vessels of the villi (Teasdale, 1981).
sampling is a complicated and time consuming technique which is uncomfortable for the labouring woman, especially if repeated at regular intervals throughout the labour.4
samples were also collected for measurements of insulin level.
Most of the [O.sub.2] in fetal blood
is carried by hemoglobin.
flow in pregnancies complicated by intrauterine growth retardation.
When fetal blood
vessels at the chorionic plate or umbilical cord are involved, fetal inflammatory response is suggested.
Exclusion criteria were (1) no other well-known condition affecting fetal blood
flow, such as intrauterine growth restriction, anemia, hypoxemia, and pregnancy-induced hypertension; (2) no history of a newborn with congenital anomalies; (3) no history of diabetes mellitus, preeclampsia, renal diseases, blood disorders, or hyperlipidemia; (4) no HIV and syphilis; and (5) no history of smoking and drinking.
We also confirmed that chorangiosis has been associated with normoblastemia of fetal blood
The frequent use of chloroform and other anesthetic agents during deliveries during this time caused newborns to experience respiratory depression from transfusion of medication from maternal to fetal blood
. Physicians began clamping umbilical cords immediately following delivery during this time to prevent additional transfusion of medication through blood.
It is the consequence of an unbalanced fetal blood
flow through communicating vessels within a shared placenta.
