What is the umbilical vein?
umbilical vein is a blood vessel that is uniquely associated with the developing fruit. It runs from placenta to a fetal liver and carries oxygenated blood and nutrients from the mother's body to a development child. During the pregnancy period, this structure also serves as an access point for the collection of fetal blood, if certain diagnostic procedures are required. The blood vessel remains open after birth for a short time and is a vascular approach for intravenous drugs when emergency treatment is necessary for very sick children. This procedure is known as catheterization of the umbilical vein. During the second month of pregnancy, the right side usually disappears and leaves the left structure that remains after birth. Maternity blood passes through the placenta and into the umbilical vein that leads directly to the liver of the fetus. In the liver, the vein branches into three vessels. From them, placental blood moves to the lower vena cava, which in turn transmits oxygenated and blood -rich blood into a fetal heart.
During pregnancy, the umbilical vein provides doctors with a minimally invasive approach to the blood circulation of the fetus to allow screening for a number of possible complications. This procedure, known as percutaneous umbilical blood sampling, allows doctors to test conditions such as anemia, as well as infections such as toxoplasmosis, herpes and rubella - which is also known as German measles. In addition, fetal blood blood screen can check blood chemistry if the child does not seem to develop as expected and can provide white blood cells to be used for chromosomal analysis. Such a test is performed by inserting a thin, hollow through the abdominal wall of the mother and into the umbilical cord. Percutaneous sampling of umbilical blood is usually performed on an outpatient basis and is described as more painful than any other needle -related procedure.
approximately one week after birth remains the umbilical vein open and viable as a source of vascular approach for an emergency physicianTreatment. While the standard intravenous line is usually a preferred treatment method, if such a location is not possible, the umbilical vein can provide prepared access to the child's vascular system. Once in place, the catheter can be used to feed intravenous fluids and drugs. The reasons for this procedure may include supplementing emergency fluid, resuscitation and stabilization before transport to another medical center.
