1. Understand the development of the fetus: Through color ultrasound, we can understand the fetal weight, head circumference, abdominal circumference and other indicators, as well as the development of various organs of the fetus, and find abnormalities in time.
2. Monitoring amniotic fluid volume: The change of amniotic fluid volume in the third trimester has an important impact on fetal health. Color Doppler ultrasound can monitor the change of amniotic fluid volume and find out the situation of excessive or insufficient amniotic fluid in time.
3. Check the position of placenta: Placenta position has an important influence on the mode of delivery. You can check whether the placenta position is normal by color Doppler ultrasound to avoid placenta previa.
4. Prevention of premature delivery: Frequent color Doppler ultrasound in the third trimester can detect cervical relaxation and uterine contraction in time to prevent premature delivery.
5. Improve the confidence of pregnant women: Through color ultrasound, we can know the health status of the fetus and make pregnant women feel more at ease.
Disadvantages of frequent color Doppler ultrasound in the third trimester;
1. Radiation to the fetus: Color Doppler ultrasound is a non-invasive examination method, but the ultrasound it uses will produce certain radiation to the fetus, which may have a certain impact on the fetus if it is carried out frequently.
2. Increase medical expenses: Frequent color Doppler ultrasound in the third trimester will increase medical expenses, which may impose a certain burden on some families with poor economic conditions.
3. Increase the psychological stress of pregnant women: Regular color Doppler ultrasound in the third trimester will make pregnant women more nervous and anxious and increase psychological stress.
