When to do four-dimensional color Doppler ultrasound for prenatal examination, and what preparations should be made in advance?

Four-dimensional color Doppler ultrasound is an important examination during pregnancy, mainly aimed at the comprehensive examination of fetal development. Through four-dimensional color Doppler ultrasound, we can more clearly see the state and development of the fetus in the uterus.

What do you need to prepare in advance to do four dimensions?

Bring your documents: Before going to the hospital, you should prepare the documents you need to bring in advance, so as not to leave on the same day, such as ID card, report of the last inspection and various documents, because the fetus is a process of continuous development. After completing each examination, the doctor will compare it with the last one to see the parts that need to be examined.

Make an appointment in advance: this is very important, because fetal examination is a very complicated process and takes a long time. If you don't make an appointment in advance, there will probably be a long queue.

Four-dimensional after meals: Because four-dimensional color ultrasound needs to make the fetus move, once the pregnant mother does not eat, it will easily lead to the situation that the fetus does not cooperate. At the same time, remember to empty the bladder before the examination to leave more room for the fetus to change its position.

Comfortable to wear: Especially during the check-up, be sure to wear comfortable clothes, try to wear clothes with slits up and down, and don't wear one-piece skirts, because if you meet a male doctor, pregnant mothers will be embarrassed when they need to leak their stomachs. In order to avoid embarrassment, it is best to wear split underwear.

When should four-dimensional color Doppler ultrasound be done?

Four-dimensional color Doppler ultrasound should be performed three times during the whole pregnancy, namely113 weeks, 6 days, 22-24 weeks and 28-32 weeks.

1 1- 13 weeks and 6 days: it is the first four-dimensional color Doppler ultrasound examination in the first trimester, which also excludes the risk of down syndrome. Mainly fetal NT examination, which is used to screen whether the transparent layer thickness of fetal neck is normal, is a very important examination in early pregnancy.

22-24 weeks: It is a very important four-dimensional screening for fetal abnormalities, such as cleft lip, spina bifida, brain, kidney, heart and bone dysplasia, so as to treat them as soon as possible.

28-32 weeks: It is an abnormality of small fetus, because the fetus is a process of continuous development and perfection, which requires continuous development and continuous examination. Just because it's passed once doesn't mean there will be no problems in the future. That's not true. This period is also a good time to take pictures of the fetus, and you can clearly see the fetal facial imaging.

Four-dimensional color Doppler ultrasound can see the fetal facial expression more clearly and stereoscopically, and the photos taken are almost what the baby looked like when he was born, which is really amazing. We can also leave a photo album for the baby and leave good memories.

All in all, four-dimensional color Doppler ultrasound is a very important examination during pregnancy. Don't miss it. If in doubt, you should communicate with the doctor in time to avoid your own doubts affecting the growth and development of the fetus.
