Umbilical cord around the neck, which makes pregnant mothers a little bit scared, online discussion has not stopped, for expectant mothers, is the baby's umbilical cord around the neck worried all day? In fact, it is better to understand what is umbilical cord around the neck to care for the baby.
The umbilical cord is the lifeline of the baby. All the viviparous animals in the mother's belly rely on the umbilical cord to get nutrition from the mother, so as to grow and develop. In humans, the umbilical cord is attached to the placenta, which is attached to the womb and provides a major responsibility for 'nutrition waste' and 'oxygen carbon dioxide' exchange.
The umbilical cord is a vein, two arteries, three blood vessels spiral around each other, like a girl's twist braid tied with a ponytail, and then surrounded by some glia (the so-called umbilical cord stem cells are stored here), the outer head wrapped with amniotic membrane to form the umbilical cord. Of course, there are very rare cases where the umbilical cord has only one artery and one vein, which is called a single umbilical artery.
Since the umbilical cord is so important, it is understandable to worry about whether it will affect the baby when it is twined. Navel around the neck can not be said to be completely risk-free, but many people have increased its risk. In particular, the cord around the neck, we are worried about the cord, not the neck!
Why do you say that? The baby can't breathe in the mother's stomach yet, so for the baby, the umbilical cord provides the nutrition and oxygen needed by the baby, not the neck! The carotid artery is deep in the neck, and the neck must be tied tightly, so that it can press on the carotid artery, causing the blood from the body to the brain to be affected. When the umbilical cord is around the neck, it is not enough to flatten the carotid artery. It has already flattened the blood vessels in the umbilical cord. For the fetus, the most important thing is the blood flow in the umbilical cord. Once it is blocked, the baby can not get the nutrition and oxygen supply. The supply of nutrients is interrupted, and there will be no problem in a short period of time. However, if the supply of oxygen is lost, the fetus will be greatly harmed soon.
The baby's position is not fixed in the middle of pregnancy, so it's not necessary to see if the umbilical cord is around the neck during the prenatal examination. Even if it's around the neck, it's not necessary. You can't do anything! Pay more attention to the fetal movement?! this is something that any pregnant woman should pay attention to. It's better to check the cord blood flow or amniotic fluid volume, which are really meaningful indicators, than to ask doctors to check the cord around the neck.
If we want to investigate, why don't we worry about the umbilical cord around our hands or feet? In fact, the smaller the cord around, the more likely it is to affect blood flow!
Anyway, what's the point of umbilical cord around the neck? People who are interested may as well use the phone to test. Take the table as the uterus, the base as the placenta, and the phone as the fetus. In fact, it's very vivid, because the umbilical cord is the same as the microphone cable, and it's wrapped like a braid.
Symptoms can occur when the cord wraps around the neck, only if:
1. Not in the case of waiting for delivery: in fact, it rarely occurs, including the umbilical cord around the body and then through the body, causing a knot, which will block the blood flow after tension; or the cord itself is too twisted and twisted, so that the blood flow can not pass through, leading to the death of the fetus; there are twins with the same egg and sheep membrane intertwined with each other, causing blood flow blocking, leading to the baby's fetal death in the abdomen; In fact, these three items are not related to neck winding.
2. In the process of waiting for labor: most of the umbilical cord around the neck will have symptoms in this period! Because usually in the mother's womb, the baby will not have a mandatory single direction of activity, if it is pulled, it will ease itself. However, if the umbilical cord is not long enough, and it becomes shorter after winding around the body or neck, symptoms will appear, including: there is no reason to prolong the birth process (being pulled); variant deceleration of fetal heart sound (the deceleration form of fetal heart sound with cord pressed); And more extreme cases of placental abruption (the phone is pulled too far and too hard to pull the whole base away from the original position); at this time, there is a real risk that the fetus may be in danger and become in need of emergency caesarean section. However, if the umbilical cord is long enough, it will probably not be dangerous, and the influencing factors are quite subtle: if the umbilical cord is long, it is easy to wrap it more, but it usually has no symptoms; if the umbilical cord is short, it will not wrap, but once it is wrapped, it will be more!
