Fetal ultrasound shows a u-shaped indentation indicating that the umbilical cord has been around the neck for one week. Although the umbilical cord around the neck has the risk of causing fetal ischemia, but one week around the neck does not need to worry too much, because the umbilical cord has a certain degree of ductility, and one week around the neck is relatively loose, the impact on the fetus is relatively small. However, if the cord is wound very tightly or wrapped around a lot of times, it will lead to fetal ischemia and lack of oxygen, or even asphyxiation and death. When you find that the umbilical cord is wrapped around the neck for one week, you can take appropriate measures to correct it, and the common methods are exercise, lying on the left side and crawling. 1. Exercise: Pregnant women can keep exercising for one hour every day to stimulate the fetus to move around in the uterus and relieve the umbilical cord by exercising. 2. Lying on the left side: Pregnant women can sleep on the left side of the bed to provide more space for the fetus to move around, thus relieving the cord from being wrapped around the umbilical cord. 3. Crawling: Pregnant women can adopt crawling position or crawling method to make the fetus rotate and turn over in the uterus, so as to relieve the umbilical cord from being wrapped around the neck. If there is no improvement after taking the above measures, or if you experience uncomfortable symptoms, it is recommended that you consult a doctor in time.
