Color Doppler ultrasound shows the umbilical cord is around the neck

After a girl becomes pregnant, she must follow the doctor's advice and go to the hospital for a pregnancy check-up in time. During the prenatal checkup, the doctor can promptly rule out various dangerous symptoms of the fetus. It has a very good effect on eugenics and good parenting. Umbilical cord around the neck is a relatively serious condition. Some pregnant women may not be familiar with this condition, so they need a doctor's guidance to avoid serious situations. So, what is the reason why color ultrasound shows that the umbilical cord is wrapped around the neck?

1. Diagnosis

With the popularity of B-ultrasound, this technology is often used to diagnose the presence of umbilical cord entanglement before delivery. In addition, the use of electronic fetal heart monitoring can also help diagnose the presence of umbilical cord entanglement. Especially during labor, frequent listening to the fetal heart rate or fetal heart rate monitoring can timely understand whether the fetus is in a dangerous condition. Doctors can make timely judgments based on this information and decide how to deal with it.

II. Treatment and Monitoring

1. Routine monitoring

The monitoring of umbilical cord around the neck is consistent with normal pregnancy monitoring and there is no need to cause excessive panic. Pregnant women also need regular prenatal checkups and learn to count fetal movements. If the fetal movements are too many or too few, they should go to the hospital for examination in time. It is not recommended for pregnant women to listen to the fetal heart rate routinely, because the normal or abnormal variations of the fetal heart rate need to be analyzed by professionals. Self-listening to the fetal heart rate often causes too many misunderstandings, psychological anxiety and unnecessary interventions.

2. Delivery method

Umbilical cord around the neck is not an indication for cesarean section. Because the incidence of umbilical cord around the neck is very high, it does not mean it is a pathological condition. Strengthening monitoring during labor will not increase the incidence of fetal/neonatal morbidity with umbilical cord around the neck.

Before delivery, B-ultrasound can be used to check whether there are umbilical cord pressure marks on the fetal body to confirm the diagnosis and check whether entanglement affects the health of the fetus. Fetal electronic monitoring can be used to observe changes in fetal heart rate. If there is irregular deceleration of the fetal heart rate or the variation is too large, it should be considered that the umbilical cord is being pulled or squeezed. The treatment of umbilical cord entanglement is mainly determined by the progress of labor and the degree of impact of the entanglement on the fetus. If the fetus shows signs of hypoxia at the beginning of labor, a cesarean section should be performed immediately. If abnormalities are discovered during the second stage of labor, the fetus should be delivered quickly. If the umbilical cord is found to be too tightly wrapped during delivery, it should be clamped and cut immediately.

3. Other progress

The resistance index of the middle cerebral artery (MCA) and umbilical artery (UA) in fetuses with umbilical cord around the neck in late pregnancy is better than its resistance index in measuring intrauterine hypoxia in fetuses with umbilical cord around the neck. It can detect intrauterine hypoxia in fetuses with umbilical cord around the neck early and make a diagnosis before fetal distress occurs, which has important clinical value.
