At 39 weeks of pregnancy, it is full-term and nearing the expected delivery date. During this period, if the umbilical cord is found to be wrapped around the neck, it is a normal occurrence and there is no need for excessive worry. Umbilical cord wrapping around the neck is a normal variation that does not affect fetal growth and development, nor does it cause fetal hypoxia, and it also does not affect the method of childbirth. Therefore, for a 39-week pregnancy with the umbilical cord wrapped around the neck there is no difference from a normal pregnancy. Just follow the normal procedures for routine prenatal checks and waiting for childbirth. If there are no signs of labor, then continue to wait until after week 40 to go to the hospital for childbirth. However, if there are signs of labor, you should go to the hospital in time, wait for childbirth, and pay attention to enhanced monitoring during the process. There is no need to intervene with the umbilical cord being wrapped around the neck, nor is there any way to proactively intervene with it.

The difference between a V-type and U-type nuchal cord.

When umbilical cord entanglement occurs, ultrasound examination may reveal a U-shaped or V-shaped entanglement. The V-shape and U-shape both indicate that the umbilical cord is wrapped around the neck once. In such cases, there is no need for excessive anxiety. Sometimes the cord may unwind by itself as the fetal position changes, loosening or alleviating the entanglement. It is important to regularly visit the hospital for prenatal check-ups, rest adequately, enhance nutrition, and adopt a left lateral position to improve placental blood supply.

What to do if the umbilical cord is wrapped around the neck once in late pregnancy?

During the late stages of pregnancy, a B-ultrasound might sometimes reveal that the fetus has the umbilical cord wrapped around its neck once. This condition is a physiological occurrence. Having the cord wrapped once around the neck does not cause intrauterine hypoxia or harm the growth and development of the fetus inside the womb. The vast majority of cases where the cord is wrapped are physiological, and whether the cord is wrapped around once or twice, there is no need for excessive worry. In the late stages of pregnancy, the most important thing when the cord is found wrapped around the neck is to monitor fetal movements. As long as the fetal movements are good, it indicates that the fetus is in a normal condition inside the womb. It is also important to keep up with regular prenatal check-ups to assess whether the fetal growth and development are normal. Additionally, it is not advised to take any action to intervene when the cord is wrapped around the neck, as neither adopting sleeping positions nor any other methods can release the cord from the neck. These methods are futile and sometimes might even harm the fetus.

Is there any danger in natural childbirth with the umbilical cord wrapped around the neck once?

Umbilical cord wrapping around the neck once is completely manageable with a natural birth, as it is very common in clinical practice, and many pregnant women with the umbilical cord wrapped around the neck have successfully delivered naturally. Even cases where the umbilical cord wraps around the neck twice, or even three times, can still undergo natural childbirth. Therefore, trying for a natural birth with the umbilical cord wrapped around the neck once is entirely feasible. Of course, during this process, it is necessary to monitor changes in the fetal heart rate or other conditions. As long as there are no issues with the fetal heart or other aspects, the mere fact of the umbilical cord being wrapped around the neck does not affect the delivery.

Can nuchal cord be corrected by lying prone?

Nuchal cord refers to a condition during pregnancy where the umbilical cord wraps around the fetus's neck or abdomen due to the baby's continuous movements and changes in position. Lying prone cannot correct a nuchal cord because the fetus can move freely within the womb. In some cases, the baby may even resolve the issue through its movements, so there is no need for excessive worry. It is only necessary to visit the hospital regularly for prenatal check-ups, follow the doctor's advice, and monitor the fetal heart rate. Generally, this does not cause any adverse effects.

Is moxibustion useful for breech presentation and nuchal cord?

Fetal breech presentation and nuchal cord can be effectively addressed with moxibustion. Breech positions are common in early pregnancy but typically resolve to a head-first position by 32 weeks and become relatively stable. Higher incidences of breech positions are noted in cases of fetal abnormalities, twin pregnancies, abnormal amounts of amniotic fluid, uterine abnormalities, and narrow pelvis. If a breech position is still present after 32 weeks, moxibustion treatment can be considered. Moxibustion is applied at the Zhiyin acupoint (located 0.1 inches beside the nail corner on the outer side of the little toe) and is generally recommended once daily for 15 to 30 minutes, with one week constituting a treatment course. Afterward, the improvement in the fetal position can be evaluated. The purpose of using moxibustion is to promote fetal activity, which may help resolve nuchal cord entanglement during fetal movements.
