What is going on around the umbilical cord?
Umbilical cord around the neck is a common condition during fetal delivery. It is generally believed that this is related to excessive umbilical cord and excessive frequency of fetal movement. The blood vessel length is expected to be longer than that of the umbilical cord, and the blood vessel curls spirally at the usual time, and the umbilical cord itself is surrounded by gelatin and has a certain degree of elasticity. Therefore, the number of weeks around the neck and the degree of survival of the fetus are not directly related to each other. Only after the childbirth, as contractions are tightened and the descending fetal head tightens the umbilical cord around it, the umbilical cord will be too short and the delivery will not be successful. The more winding weeks there are, the more dangerous it is. Through B-ultrasound examination, you can see whether the fetus has umbilical cord around the neck before delivery, and sometimes the abdomen can hear more obvious umbilical murmurs. Therefore, it is more necessary to listen to fetal heart rate and pay attention to fetal movement so that timely measures can be taken.
What is the cause and harm of umbilical cord entanglement?
Umbilical Cord Wound is a type of umbilical cord abnormality. It is the most common type of umbilical cord abnormality. It is one of the most important types of umbilical cord abnormality. Another type of person who does not completely wrap around the neck is called the umbilical cord. Followed by the winding of the trunk and limbs, often mothers are collectively referred to as the umbilical cord around the neck or umbilical cord wrapped around the neck. The incidence of umbilical cord twins was 20% to 25% in the neck, and the incidence of umbilical cord around the neck was 89%. The rate of umbilical cord around the neck was 11%. The umbilical cord around the neck for 3 weeks or more was rare. Umbilical cord wrapped baby's trunk and limbs are rare.
the reason
Fetal baby is not honest in the mother's body, it tumbling in the uterus where space is not very large, often activities. The characteristics of each baby are different, some baby moves more gently, some babies move more, and they love sports. He moves in the womb's uterus, plays games, moves his arms, stretches his legs, and turns around again. At this time, umbilical cord entanglement may occur.
harm
Umbilical cord around the neck is a high-risk pregnancy, at any time can cause intrauterine fetal distress. If the umbilical cord is wrapped around at the end of pregnancy, it is very dangerous for the baby, and tightly wounded can affect the passage of the umbilical cord blood flow, which affects the metabolism of oxygen and carbon dioxide of the baby's baby and causes the baby's heart rate to slow down. In severe cases, there may be a lack of oxygen in the fetus and even the death of the baby.
Umbilical cord around neck common problem
Question one: If the umbilical cord around the neck, the baby will not be dangerous?
Professor Zheng A: Umbilical cord around the neck is more common, in fact, not terrible, the incidence of umbilical cord around the neck during pregnancy is 20% to 25%, most around the neck a week, a few weeks around the neck, more than three weeks is rare. Most fetuses do not show any abnormalities and do not have to panic.
Question 2: My body has been very healthy. The previous examination was normal. Why did the umbilical cord go around neck?
Professor Zheng A: There may be too much amniotic fluid, the fetus in the uterus is very space for exercise, causing the umbilical cord to circumnavigate the neck; others may be due to the long umbilical cord, or the relatively small size of the fetus. If your baby moves too often in the uterus, it can also go around the neck, and the umbilical cord may also wrap around other parts of the body. However, the umbilical cord is elastic and the umbilical cord will not affect the blood flow of the umbilical cord and will not endanger the fetus.
Question 3: What should we pay attention to after the umbilical cord is wrapped around the neck?
Prof. Zheng: You have to relax your heart. After returning home, you must learn how to count fetal movements. Count the number of fetal movements within one hour of each morning, evening and evening, and multiply the number of three fetal movements by four, which is the number of fetal movements for 12 hours. Fetal movement should be greater than 10 times in 12 hours. If a sudden large number of fetal movements occur suddenly, rush to the hospital for examination. When the fetal movement is too small, it is necessary to come to the hospital for examination. Regular prenatal checkups can detect abnormalities such as too much or too little amniotic fluid and abnormal fetal position as early as possible; the conditions of the umbilical cord can also be judged by methods such as fetal heart rate monitoring and ultrasonography.
