What should I 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 them on the same day, such as ID card, report of the last examination and various documents, because the fetus is a process of continuous development. After completing each examination, the doctor will compare them with the last one to see the parts that need to be examined emphatically.
Make an appointment in advance: this is very important, because the 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 eating: Because four-dimensional color ultrasound needs to let the fetus move, once the pregnant mother doesn't eat, it will easily lead to the fetal uncooperative situation. At the same time, remember to empty the bladder before the examination, leaving more room for the fetus to change position.
Comfortable to wear: especially during the check-up, you must wear comfortable clothes, try to wear clothes that are split up and down, and don't wear one-piece skirts, because if you meet a male doctor, the pregnant mother will be embarrassed when she needs to leak her stomach. In order to avoid embarrassment, it is better to wear split underwear.
When should four-dimensional color Doppler ultrasound be done?
Four-dimensional color Doppler ultrasound needs to be done 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 early pregnancy, and it also excludes the risk of Down's syndrome. It is mainly the fetal NT examination, which is used to screen whether the thickness of the transparent layer of the fetal neck is normal, and it is a very important examination in early pregnancy.
22-24 weeks: It is a very important and four-dimensional screening for fetal malformations, such as cleft lip, spina bifida, brain, kidney, heart and skeletal dysplasia, so as to be treated as soon as possible.
28-32 weeks: It's a small fetal anomaly, because the fetus is a process of continuous development and improvement, which requires continuous development and continuous examination. It doesn't mean that there will be no problems in the future after passing it once. It's not like this. This period is also a good time to take pictures of the fetus, and you can see the fetal facial imaging clearly.
Four-dimensional color Doppler ultrasound can see the fetal facial expression more clearly and stereoscopically, and the photos taken are almost the appearance of the baby just after birth, which is really amazing. We can also leave a photo album for the baby, which can also leave a good memory.
All in all, four-dimensional color Doppler ultrasound is a very important examination during pregnancy. Don't miss it. If you have any questions, you should communicate with your doctor in time to avoid that your doubts will affect the growth and development of the fetus.
