Be pregnant 20 weeks to do what check? From the 20th week of pregnancy, expectant mothers are getting closer and closer to the expected date of delivery. Have a prenatal checkup every week. The following is the schedule of birth inspection:
1.20 ~ 25 weeks (fifth physical examination)
Examination items: edema and prevention of premature delivery.
After 20 weeks of pregnancy, doctors should check whether there is edema for expectant mothers one after another. In addition, expectant mothers 37 weeks ago should pay special attention to prevent premature delivery. If the pain continues to worsen for more than 30 minutes, and there is vaginal bleeding or water discharge, you must immediately send it to the hospital for examination.
2.26 ~ 35 weeks (seventh physical examination)
Examination items: B-ultrasound assessment of fetal weight.
At the 34th week of pregnancy, it is recommended that the expectant mother do a detailed B-ultrasound to evaluate the weight and development of the fetus at that time (for example, the fetus in pre-eclampsia will look petite) and estimate the weight of the fetus until full-term delivery.
Third, 36 weeks (the eighth physical examination)
Production inspection items: prepare production matters.
Article 8 The inspection of production inspection is to prepare for production matters.
4, 37 weeks (ninth physical examination)
Check items: pay attention to fetal movement.
Due to the more frequent fetal movements, expectant mothers should always pay attention to the fetus and their own situation to avoid premature delivery.
Five, 38 ~ 42 weeks (tenth check-up)
Check items: fixed fetal position, delivery, preparation for delivery, and consideration of delivery.
From the 38th week, the fetal position is fixed, and the fetal head has come down and stuck in the pelvic cavity. At this time, expectant mothers should be prepared to give birth at any time. Some expectant mothers still have no signs of delivery after 42 weeks, so doctors should consider using oxytocin.
How to distinguish between men and women in 20 weeks of pregnancy Many people say that 20 weeks of pregnancy can be based on color Doppler ultrasound to see gender. Four-dimensional color Doppler ultrasound is a kind of ultrasound examination, which not only has the function of color Doppler ultrasound, but also can stereo image the head and face of the fetus, so you can clearly see the baby's five senses. Through these, doctors can optimistically judge whether the fetus is congenital malformation, and can also observe other conditions of the fetus, such as the sex of the fetus.
However, it is forbidden to check the sex of the fetus in China, and if the doctor reveals the sex of the fetus, he will also be investigated by law. Therefore, when doing four-dimensional color Doppler ultrasound, doctors generally avoid the lower body of the fetus and will not show the reproductive organs of the fetus on the image. Moreover, for young parents, both boys and girls are the treasures of this family. Understanding the healthy development of the fetus is the significance of doing four-dimensional color Doppler ultrasound.
However, some folk sayings are judged by some data of B-ultrasound, such as the size of gestational sac and the share value of biparietal diameter, but this judgment method is not necessarily accurate.
