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]
Umbilical cord prolapse may occur, particularly in the complete, footling, or kneeling breech. [23] This is caused by the lowermost parts of the baby not completely filling the space of the dilated cervix. [23] When the waters break the amniotic sac, it is possible for the umbilical cord to drop down and become compressed. [23]
Further analysis suggested that waiting two or more minutes to clamp the cord had a 91% probability of being the best treatment to prevent death shortly after birth in premature babies.
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]
Umbilical granuloma is the most common umbilical abnormality in newborn children or neonates, causing inflammation and drainage. [1] [2] [3] It may appear in the first few weeks of newborn infants during the healing process of the umbilical cord due to an umbilical mass. [4] It is the overgrowth of the umbilical tissue. [5]
During the 1950s there were outbreaks of omphalitis that then led to anti-bacterial treatment of the umbilical cord stump as the new standard of care. [5] It was later determined that in developed countries keeping the cord dry is sufficient, (known as "dry cord care") as recommended by the American Academy of Pediatrics. [2]
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels.
