Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
HIE results from placental abruption, umbilical cord problems, uterine rupture, or the failure to identify abnormal heart rate by the medical staff. [ 26 ] Placental disorders associated with perinatal stroke range from anatomical (site or degree of implantation) such as placenta previa [ 27 ] to placenta-maternal effects ( fetal ...
The embryo is surrounded by the thin membranes of the amniotic sac, the umbilical cord is seen in the center, attaching the embryo to the placenta. The umbilical cord develops from and contains remnants of the yolk sac and allantois. It forms by the fifth week of development, replacing the yolk sac as the source of nutrients for the embryo. [2]
In accordance with WHO, perinatal asphyxia is characterised by: profound metabolic acidosis, with a pH less than 7.20 on umbilical cord arterial blood sample, persistence of an Apgar score of 3 at the 5th minute, clinical neurologic sequelae in the immediate neonatal period, or evidence of multiorgan system dysfunction in the immediate neonatal ...
A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck. [1] Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and bleeding in the whites of the eye. [1] Complications can include meconium, respiratory distress, anemia, and stillbirth. [1]
Delaying the clamping allows blood to flow from the placenta to the baby while the baby’s lungs fill with air.
Umbilical cord prolapse is when the umbilical cord comes out of the uterus with or before the presenting part of the baby. [2] The concern with cord prolapse is that pressure on the cord from the baby will compromise blood flow to the baby. [2] It usually occurs during labor but can occur anytime after the rupture of membranes. [1] [5]
Occasionally, during pregnancy, there is a single umbilical artery (SUA) present in the umbilical cord, as opposed to the usual two. [1] This is sometimes also called a two-vessel umbilical cord, or two-vessel cord. Approximately, this affects between 1 in 100 and 1 in 500 pregnancies, making it the most common umbilical abnormality.
