When there is a situation of umbilical cord around the neck, pregnant women need to regularly visit the hospital for an ultrasound checkup to understand the condition of the umbilical cord entanglement, mainly to monitor the umbilical blood flow. If there is an increase in umbilical blood flow, it indicates that the cord entanglement is tight, which can affect the baby's safety, potentially leading to lack of oxygen or suffocation. Therefore, in the late stages of pregnancy, it is also necessary to go to the hospital every 3-7 days for fetal heart monitoring to check if there is any lack of oxygen in the fetus while inside the womb. If there is fetal hypoxia in the late stages of pregnancy, it is advisable to terminate the pregnancy in a timely manner.

Does the baby not move much when the umbilical cord is wrapped around the neck and there is not much amniotic fluid for one week?

When umbilical cord wrapping around the neck occurs during pregnancy, it generally does not affect the fetal limb movement. However, a decrease in amniotic fluid can affect the baby's movements. When amniotic fluid decreases, the baby has less room to move inside the uterus, thus causing reduced fetal movements. It is recommended to regularly visit the hospital for prenatal check-ups. If a reduction in amniotic fluid occurs, it is important to promptly identify the reason and then proceed with appropriate treatment. Regular monitoring of fetal movement changes is advised, and fetal heart monitoring can be done to assess the safety of the fetus. Drinking more water to replenish amniotic fluid is also advisable.

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.

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.

Will there be changes in the fetal heart rate if the umbilical cord is wrapped around the neck?

When the umbilical cord is wrapped around the neck, there are some situations where changes in the fetal heart rate may occur. The umbilical cord is mostly wrapped around the neck just once, which generally does not affect the growth and development of the fetus, nor does it significantly change the fetal heart rate. The impact on the fetal heart rate in the case of nuchal cord depends on how tight the cord is wrapped around the neck, the number of loops, and the length of the umbilical cord, among other factors. If the umbilical cord is tightly wrapped and has multiple loops, or if it is compressed due to contractions of the uterus, it can obstruct fetal blood circulation and lead to hypoxia in the fetus, thereby affecting the fetal heart rate.

How to correct the umbilical cord wrapped around the neck once?

The umbilical cord is wrapped around the neck once, and there is no way to correct it; it cannot be rectified by changing position or through medication. The umbilical cord being wrapped around the neck once can be due to the umbilical cord being relatively long, or the fetus having a large range of movement within the womb. During pregnancy, as the fetal movements change, it might wrap around twice or even three times, although it's also possible that there will be no wrapping of the umbilical cord around the neck by the end. There is no need to panic if the umbilical cord is wrapped around the neck once. Pay attention to fetal movements and attend regular prenatal check-ups. If there is an increase or decrease in fetal movements, it is important to visit the hospital promptly to have an ultrasound, listen to the fetal heartbeat, and check for any signs of fetal hypoxia. If fetal hypoxia is present, oxygen therapy should be administered, and pregnancy termination may be necessary if required.
