Umbilical cord wrapping is a common physiological phenomenon during pregnancy, mainly because the length of the umbilical cord during pregnancy generally ranges from 30cm to 80cm, which far exceeds the length needed for fetal growth and development. Therefore, occurrences like the umbilical cord wrapping around the neck or limbs are quite normal. An umbilical cord around the neck is not an indication for cesarean section, and a vaginal delivery is entirely feasible, even if the cord wraps around the neck once or even twice. However, due to the special circumstance of the umbilical cord being wrapped around the neck, it is crucial to pay attention during the delivery process. First, it is important to monitor the fetal heart rate closely, as umbilical cord wrapping can lead to fetal hypoxia, which would be indicated by changes in the fetal heart rate. Second, preparations for an emergency cesarean section should be in place in case of an abnormal fetal heart rate, at which point a cesarean may be necessary to terminate the pregnancy.

Does the umbilical cord wrapping always involve the neck?

Umbilical cord entanglement around the neck usually occurs during the mid-pregnancy period, as this is when the baby moves more frequently. The baby has a larger range of movement within the uterine cavity, which can easily lead to the cord wrapping around the neck, abdomen, legs, or arms. Generally, if there is no cord entanglement found after 32 weeks of pregnancy, it is unlikely that it will occur. However, this is not certain. After the baby engages, which is after 35 weeks, the baby's position becomes fixed, and it is unlikely for cord entanglement to occur thereafter.

Can you have a natural birth if the umbilical cord is wrapped around the neck twice?

The umbilical cord wrapped around the neck twice is something that can definitely be attempted, meaning a trial of natural delivery, or vaginal trial. Clinically, there have been many cases where the umbilical cord was wrapped around the neck twice, and the baby was delivered smoothly. Therefore, it's unnecessary to avoid a trial of delivery and opt for cesarean section just because the umbilical cord is wrapped around twice; that would be somewhat excessive. Of course, when the cord is wrapped around the neck twice, since the wrap is relatively tight, the remaining length of the cord might be short, and when the baby's head moves downward, there could be changes in the fetal heart rate, but not necessarily in all cases. Therefore, for pregnant women with the umbilical cord wrapped around the neck twice, doctors will closely monitor changes in the fetal heart rate during the delivery process.

What should I do if the umbilical cord is wrapped around the neck once during the mid-pregnancy?

The incidence of the umbilical cord wrapping around the neck once is quite high, accounting for about one-fifth of pregnant women. Generally, if the umbilical cord is loosely wrapped around the child's neck, and if the cord is long enough, it usually does not have a significant impact on the fetus. However, if the umbilical cord is tightly wrapped around the neck, and additionally, if the cord is relatively short, it can sometimes lead to pulling and thinning of the cord, causing obstruction in the blood vessels within the cord. This can result in oxygen deficiency for the baby. Therefore, during the mid-pregnancy period when umbilical cord entanglement occurs, it is important to enhance monitoring. Regular prenatal check-ups, counting fetal movements by oneself, and frequent monitoring of fetal heart rate changes are advisable.

Is it dangerous for the umbilical cord to be wrapped around the neck during the mid-stage of pregnancy?

During a mid-pregnancy ultrasound, it is sometimes indicated by the presence of a U-shaped or W-shaped notch behind the fetus's neck that the fetus may have the umbilical cord wrapped around its neck. During pregnancy, it is perfectly normal for the umbilical cord to wrap around the neck, and it generally does not affect the fetus or pose any danger. The length of the umbilical cord during pregnancy is approximately 30 to 80 centimeters, which is quite long relative to the size of the uterine cavity. Hence, many umbilical cords have excess length that can wrap around the neck or limbs of the fetus, leading to the umbilical cord being coiled around the neck or limbs. However, current research indicates that whether the umbilical cord is wrapped around the neck or limbs once or twice, it does not affect the fetus. It does not cause intrauterine hypoxia or affect the growth and development of the fetus, nor does it influence the mode of delivery. A natural childbirth can still be an entirely viable option.

What should I do if the umbilical cord is wrapped around the neck once?

Umbilical cord wrapping around the neck once is a very common phenomenon, occurring in 20% of fetuses. When the umbilical cord wraps around the neck once, if the umbilical blood flow and fetal movements are normal, it indicates that the cord wrapping does not affect the fetus and will not have a direct impact on the fetus's intrauterine growth and development. However, during childbirth, attention must be paid to the possibility that the umbilical cord wrapping may cause difficulties in the descent of the presenting part of the fetus, leading to abnormal umbilical blood flow. If difficulties in the descent of the presenting part and changes in the fetal heart rate occur during delivery, the possibility of umbilical cord wrapping should be considered. If necessary, a cesarean section should be performed to terminate the pregnancy. There are no medications or other treatments that can alleviate umbilical cord wrapping; instead, enhanced prenatal monitoring is sufficient.
