If the umbilical cord is wrapped around the neck for one week at 16 weeks of pregnancy, if there is no obvious fetal heart abnormality in the ultrasound examination of the fetus, generally no special treatment is needed, and the fetus may move in the opposite direction and unwind by itself when it moves around during pregnancy. However, if the umbilical cord is too short or too tightly wound, corresponding measures need to be taken to avoid adverse consequences caused by fetal hypoxia. If the fetus does not have abnormal fetal heartbeat or malposition, the pregnant woman should pay attention to the obstetric examination on time and closely monitor the growth and development of the fetus. In addition, pregnant women can increase the exercise, and the cord can be detached by itself as the fetus moves on its own. It is also recommended that pregnant women with umbilical cord entanglement should increase the number of checkups during pregnancy, and monitor the change of amniotic fluid volume, fetal position, and fetal heart rate, so as to detect the symptoms of fetal hypoxia in time, and then correct them quickly. When fetal movement decreases or fetal heart rate monitoring is abnormal, it is necessary to consider whether the fetus has intrauterine hypoxia or intrauterine distress. If intrauterine distress occurs, oxygen can be inhaled to increase the blood oxygen level of the mother, and in addition, the supine position can be changed to lateral position to improve the blood circulation of the uteroplacental placenta and increase the supply of oxygen to the fetus. The phenomenon of umbilical cord around the neck is usually found by pregnant women during pregnancy through pregnancy ultrasound, mostly due to the umbilical cord is longer, more amniotic fluid or fetal activity caused by a larger amplitude, generally through close observation of fetal movement can be, fetal movement abnormalities need to consult a doctor in a timely manner.
