Nuchal Cord
Does an umbilical cord around the neck always require a cesarean section?
When nuchal cord occurs, it is not always necessary to perform a cesarean section, because sometimes the cord may be loosely wrapped around, even if only for one loop, and in such cases, natural childbirth is still possible. However, if the nuchal cord is wrapped more than two or three times, and is tightly wrapped, and if there is fetal hypoxia inside the uterus, then a cesarean section must be performed to quickly terminate the pregnancy. Nuchal cord is a common cause of difficult labor in pregnant women. Therefore, during the later stages of pregnancy, regular prenatal check-ups should be carried out to monitor the fetus's health. If any abnormalities are detected, it is urgent to admit to the hospital for delivery to avoid potential impacts on the baby, such as hypoxia or asphyxiation.
Can you have a vaginal birth if the umbilical cord is wrapped around the neck once?
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.
How to correct nuchal cord with one loop?
Nuchal cord occurs because the fetus moves frequently within the uterine cavity, which can result in the umbilical cord looping around the neck once, referred to as a single-loop nuchal cord. In fact, it is not correctable because it is impossible to physically reach the umbilical cord or the fetus during pregnancy. Moreover, a single-loop nuchal cord is quite common, occurring in about one-fifth of all pregnancies. If the loop is loose or the umbilical cord is sufficiently long, there is generally no significant impact on the baby. However, if the loop is tight, it can pull on the umbilical cord, causing the blood vessels within the cord to narrow. This may lead to noticeable changes in fetal movements and heart rate. Therefore, with a nuchal cord, it is important to enhance monitoring and pay attention to changes in fetal movements and heart rate.
Why doesn't the ultrasound show the umbilical cord around the neck?
Generally, in cases where there is umbilical cord entanglement around the neck, it can be detected through an ultrasound examination. However, if the ultrasound does not show the umbilical cord wrapped around the neck, it is possible that the cord moved back around as the fetus moved during pregnancy. It might also be that the cord is not fully wrapped around the fetus's neck, but rather draped over the shoulder or neck. This situation could also relate to the fetal position, making it undetectable.
Can umbilical cord around the neck perform fetal position correction?
In cases of nuchal cord, it is not advisable to attempt correcting abnormal fetal positions, because if the fetal position changes abnormally after an attempted correction while the umbilical cord is wrapped around the neck, it may worsen the degree of the nuchal cord, potentially leading to fetal hypoxia or even asphyxiation. However, if the umbilical cord is relatively long, it might not affect the changes in fetal position, and sometimes the fetus can automatically free itself from the nuchal cord through its own movements. It is important to regularly visit the hospital for prenatal check-ups to detect any other potential abnormalities.
