Pregnancy is a happy event. As your baby grows bigger and bigger, your worries increase. When you get the ultrasound report, you will see a “V” or “W” shape pressure mark on the fetal neck, etc. What does this mean? What does this mean? In fact, these are indirect signs of cord winding. “V” means the baby may have 1 turn of cord winding; “W” means the baby may have 2 turns of cord winding. Usually, when you see the diagnosis of cord winding, the first reaction of mothers-to-be is that their babies are wrapped around their necks like a rope, and they will be very nervous – “Is the baby in danger? Will it suffocate? What should we do? Will we still be able to deliver naturally?” …… About 50% of fetuses have the umbilical cord wrapped around their neck, so it is very common because the cord is very long, the normal length is usually about 50 cm, floating in the amniotic fluid, and the fetus is moving every day, so it is easy to wrap itself around. Most umbilical cords are wrapped around the neck for 1-2 weeks, a few for more than 3 weeks. Whether the fetus is in danger or not is related to the tightness of the winding. If the winding is too tight, the fetus will be at risk of oxygen deprivation or even death. When the fetus is deprived of oxygen, it usually shows restlessness or decreased fetal movement. Fortunately, most fetuses are loosely wound. The fetus that is already wrapped around the neck may also wind itself out. The relationship between the umbilical cord and the neck is only two kinds of cases: the umbilical cord hitching neck and the umbilical cord winding neck. The umbilical cord is not wrapped around the neck, just like hanging a scarf around our neck, it is at most 180° around the neck, not in a circle at all, this situation is very safe for the fetus. Most of them will unwind on their own as the fetus turns. Even if it cannot be untied, as long as it is not wound too tightly, the fetus will not be in great danger, even during the delivery process, it will not strangle the child and cause fetal hypoxia. As long as the fetus does not suffer from hypoxia, they can deliver naturally, so mothers-to-be do not need to panic when they hear that the umbilical cord is wrapped around the neck. 3.What should I do if the umbilical cord is wrapped around my neck? How can I tell if the cord is tightly wound or not? How do I know if the fetus is hypoxic? After the cord is wrapped around the neck, you can combine it with the fetal heart monitoring results to determine the presence of fetal hypoxia. Ultrasound can determine early hypoxia by monitoring the umbilical artery blood flow S/D value and middle cerebral artery blood flow S/D value in late pregnancy. Of course, you can also determine the number of fetal movements by counting the number of fetal movements as follows: Normal fetal movement count is greater than 10 times per hour. The mother-to-be is generally required to count the fetal movements once a day for one hour in the morning and one hour in the evening. The normal fetal movement is at least 3 times or more per hour. Sometimes there will be a series of fetal movements, then it will be counted as one time, and another time after 5-6 minutes. The mother-to-be should learn to count the fetal movements. If there is no fetal movement for more than 24 hours in a row, or if the fetal movement is particularly frequent at a certain time, you should go to the hospital for examination. In addition, there are some other points that need to be noted: when the umbilical cord is found to be wrapped around the neck in late pregnancy, along with fetal malposition and the fetal head is not in the pelvis, the fetal position cannot be corrected by correcting the body position to prevent the umbilical cord from being wrapped tighter in excessive fetal movement. Try to reduce vibration and avoid riding on bumpy roads. The mother-to-be sleeps more in the left side position to increase the blood flow to the placenta of the uterus. You can put two pillows under your thighs to make it more comfortable.
