How many weeks of pregnancy should be done when the large discharge deformity is appropriate

I gave birth to my eldest son at 22 weeks, and now I am pregnant with my second child, so I made an appointment to do it at 23 weeks.

Both times were in the best tertiary hospital in the city, and I asked the director, who said that the hospital stipulates that 20 to 24 weeks is the best time to do large deformity, and the most clear and accurate results are seen.

15 20 weeks is the time for Tang screening, not the time for large ultrasound.

Hello, this condition is usually between 20 weeks and 24 weeks to go for a deformity examination. Do a check on the fetal position and umbilical cord once between 30 and 33 weeks of pregnancy, and do a full examination before delivery.

Macroplasia generally refers to a comprehensive ultrasound examination of the fetus. The best time for systematic or four-dimensional ultrasound is between 22-26 weeks of pregnancy, and the cost of the examination is about 300 yuan. Of course, the generalized large deformity also includes the screening of fetal chromosomal abnormalities, NTB ultrasound at 11-13 weeks of pregnancy, about 100 yuan.

The early and mid-stage Down screening blood draw is 9-13 weeks in the early stage and 16-19 weeks in the middle stage, and the total cost is about 200-300 yuan. 16-24 weeks of non-invasive DNA blood drawing, the cost is about 2000 yuan. Amniocentesis for 18-24 weeks costs about 3,000 yuan, of course, non-invasive DNA and amniocentesis are not routine examination items, and the doctor chooses according to the needs of the condition.

Large deformity, also known as systematic ultrasound, its purpose is to screen the fetus for structural malformations during pregnancy, and there is a time requirement to do large deformity ultrasound in clinical work, neither too early nor too late, and it is generally recommended to do large deformity B ultrasound at about 24 weeks. Because the organs of the fetus have been fully developed at about 24 weeks, and the amniotic fluid is sufficient, and the fetal size is more appropriate, in this case, the fetus can be more accurately found whether the fetus has structural malformations. However, if the ultrasound is done too late, due to the relatively large size of the fetus, the amniotic fluid volume will be slightly reduced, which is not conducive to the observation of various structures of the fetus.

Hello, it is better to do 4D color ultrasound between 22 and 28 weeks of pregnancy. At that time, the amniotic fluid was also a little clearer. The baby's body is almost developed. It can be better checked.

Four-dimensional color ultrasound can be done in six months of pregnancy, and three-dimensional examination can be used at other times, generally B ultrasound is checked once in two months in the first two months of pregnancy, B ultrasound once a month in the middle of pregnancy, B ultrasound once in half a month in the late stage of pregnancy, once a week before delivery, and the fetal development can be checked regularly, as long as there is no abnormality, the examination B ultrasound has no effect on fetal development, and it can be checked repeatedly

Generally, four-dimensional color ultrasound is done around 24 weeks of pregnancy for large deformity, because at this time, most of the fetal organs are relatively well developed.

Four-dimensional deformity? The doctor prescribed me a three-dimensional ah, LG went to make an appointment today, and the person who made the appointment said that it was too big to do, and I am only 18W now, and I can't make an appointment with NND

It is recommended that you can wait until 20 weeks to 27 weeks of pregnancy, to do the four-dimensional deformity, at this time the results are the most accurate, I am in Tianjin Tianpregnancy Hospital to do the four-dimensional deformity, you can go to this clinic to see.

Generally, it is about 24, and the baby's development is more complete to see more clearly, and the imaging is not very clear too early.

Generally, 5-6 ultrasounds, or even more, should be done throughout the pregnancy. In the second trimester, some hospitals often order 1-2 ultrasounds. If only one ultrasound is scheduled, most hospitals will arrange it between 22-24 weeks of pregnancy.

Arrange 2 ultrasound examinations, once every 20 weeks and once every 24 weeks in some hospitals. Why aren't these ultrasounds scheduled for weeks, or even younger? Because the fetal organs are too small to develop during these weeks of pregnancy, it is difficult to determine the abnormality of some important organs, and most doctors choose to do it after 20 weeks of pregnancy.

If the hospital can arrange to do it once around 22 weeks of pregnancy, or once at 20 weeks, it is reasonable to do it once at 24 weeks. After 24 weeks, as the fetus continues to grow, some hospitals may add another ultrasound at about 28 weeks to understand the growth and development of the fetus. At the same time, it is necessary to continue to observe whether there are some abnormalities in the fetus during development.

If you have a pregnancy test at a certain hospital, follow the hospital's recommendations to arrange for an ultrasound. In the event of a birth defect or abnormal development of the fetal organs, the doctor will further arrange for a consultation with a higher-level hospital. If there are very special circumstances, it is necessary to communicate with the doctor of the prenatal examination in time to further clarify the diagnosis of fetal development.

Well, that's a little late. Ask the doctor, I don't want to advise. I'll just tell you this approximate time. I was 23 weeks old, and then I went to see 4D three weeks later. It's pretty clear.

Hello, the 400-dimensional color ultrasound examination is mainly used for the examination of large deformities during pregnancy, which is generally carried out between 20 and 28 weeks of pregnancy, and the best time period is between 22 and 26 weeks. This time period is the period of rapid development of the brain, the structure of the fetus has been formed, the size of the baby and the amniotic fluid are moderate, the fetal bone echo is relatively affected, and the image is relatively clear. Choose a regular hospital to make an appointment for a check-up in advance.

Color ultrasound examination can exclude most fetal malformations, such as neonatal congenital heart disease, cleft lip and palate, edema fetus, polydactyly (toe) and external ear and other malformations, but due to different times and different fetal positions, the images generated are also different, so it is not possible to completely exclude all fetal malformations. Therefore, remind everyone to be sure to do pregnancy check-ups on time.

We all know that a deformity test is a very important test for both the fetus and the pregnant woman. Deformity examination can effectively reduce the birth rate of malformed fetuses and ensure the health of the baby to a greater extent. However, some women are not sure when to perform the deformity examination.

SoIt is best for pregnant women to do large deformities in a few weeksThis?

Generally, pregnant women can be examined at about 18-28 weeks of pregnancy, and four-dimensional color ultrasound can display the color, face, and development of various organs of the fetus in three dimensions, and even the state of the fetus in the mother's body can also be observed; It can be early diagnosis of fetal malformations, such as cleft lip, cleft palate, abnormal bone development, cardiovascular malformations, etc. Understand the intrauterine dynamics of the fetus, and then dynamically record the intrauterine status of the fetus for permanent memorial.

Generally, Down's screening is done around 17 weeks, which is to check for fetal neural tube malformations, and at 24 to 26 weeks, you can do a three-dimensional B ultrasound, which can intuitively see the development of the fetus, and you can check whether the fetus has a cleft lip and palate, visceral development, etc.

It is best to do an ultrasound examination at 18 to 20 weeks of gestation, during which the fetus has fully developed all organs, and a careful ultrasound examination can see if there is any abnormality in each important organ. Fetal malformations can be detected at an early stage, and the pregnancy can be terminated in time, and the impact on the mother's body is also small. Later, if there are no abnormalities, you can wait until the last few weeks of pregnancy to have another ultrasound test to estimate the size of the fetus, the position of the placenta and the amount of amniotic fluid.

During pregnancy, regular pregnancy tests should be done and the development of the fetus should be closely observed. Color ultrasound examination is necessary, and obvious limb abnormalities or deformities can be identified, but not absolutely. It is advisable to follow the advice of the clinician according to your own situation.

1. How difficult is it to give birth: prenatal examination is also very important for childbirth, through a comprehensive system examination, you can understand the posture and development of the fetus in the mother's body, and then carry out **, understand the difficulty of childbirth, so that you can take corresponding measures to make up for it.

2. Early detection of pregnancy complications: Some pregnancy complications can be detected early through prenatal examination. Such as pregnancy toxicity, placenta previa, early placental abruption, etc., these serious complications have a certain threat to the life of pregnant women and fetuses.

Most of the various pregnancy complications occur in pregnant women who do not have antenatal care, and most of these complications can be prevented by prenatal detection and measures. Therefore, no matter how busy a woman is at work, she should never go for a prenatal check-up on time because she is afraid of trouble.

3. You can learn about the development of the fetus: the expectant mother regularly goes to the hospital for prenatal examination, and through hysteroscopy, etc., she can understand the development of the fetus, whether there is any abnormality, such as dysplasia, malformation, etc., if there is an abnormality, remedial measures can be taken in time to protect the health of the expectant mother and the fetus. If it is not possible to continue the pregnancy, the pregnancy needs to be terminated.

4. Keep abreast of fetal development: Regular prenatal check-ups can help you understand and master the development of the fetus.

We all know that pregnant women need to have some tests before, during and after pregnancy, and these tests can protect the health of the fetus and the mother. Among them, large deformity is a test that pregnant mothers need to do, which can rule out fetal malformations. So, when is the pregnancy deformity done?

Next, let's take a look!

At present, the main tool for deformity removal in obstetric hospitals is four-dimensional color ultrasound, and the best time to do four-dimensional color ultrasound is that the fetal limbs and major organs have all developed after 16 weeks of pregnancy, and the best examination time is 24-28 weeks of pregnancy, and the amount of amniotic fluid is more suitable for fetal malformation screening. Generally, at about 24-28 weeks, you can do four-dimensional color ultrasound prenatal deformity, which can three-dimensional display of the fetus's color, face, the development of various organs, and even the state of the fetus in the mother's body. It can be early diagnosis of fetal malformations, such as cleft lip, cleft palate, abnormal bone development, cardiovascular malformations, etc.

Generally, there is a B-ultrasound at about 20 weeks of pregnancy, which is seen more carefully and comprehensively, mainly to discharge the malformation. Future ultrasound will also be seen, but the focus is on measuring the fetal neckline to see whether the growth and development rate is normal, and the fetus is of moderate size within this gestational week, and the ultrasound imaging is clearer. There is no need to have an empty stomach before doing the "large deformity" examination, and it is best to eat a good breakfast, because the baby will move more strongly after eating good things.

You can bring some small snacks or chocolates, "big deformity" examination to see many parts of the fetus, once the angle is wrong, the doctor will not see clearly, may let you go out for a walk, eat some sweets, promote the baby to move, the baby moves the angle is right, the doctor can check in all directions.

The first check-up should be done at 3-4 months of pregnancy, and the gestational age should be 11-14 weeks. During this period, the baby's development and activity status can be observed as a whole, potential chromosomal indicators such as fetal NT values can be screened, and some serious fetal structural malformations can be diagnosed. The second examination should be done at 4-5 months of pregnancy, and the gestational age should be 17-20 weeks.

During this period, the hands and feet of the fetus in utero have been preliminarily formed, and the extension and development of the fetal hands and feet are observed, and the fetal hand and foot malformations are more clearly diagnosed. The third examination: the best time for this deformity is 5-6 months pregnant, and the gestational week is 20-26 weeks.

This period is very important for the baby, the four-dimensional color ultrasound system can completely detect the baby's development, screening and diagnosis of fetal structural malformations, hereditary diseases, etc., which is the best period for deformity. The fourth check-up is preferably 7-8 months of pregnancy and 32-34 weeks of gestation. This period of time is mainly to assess the survival status of the fetus, check the baby's later development, such as kidney and heart abnormalities, and provide valuable information for the fetus that should be born as close as possible to the expected date of birth, or choose the right time to be born.

The fifth check-up will take place from September to before delivery. Before labor, the fetal position should be determined, mainly to check whether the amniotic fluid is reduced, the maturity of the placenta, whether the baby is safe in the mother's belly, and at the same time indicate the baby's weight and development, so as to prepare for childbirth.

The best time to do things is 11-14 weeks, 22-24 weeks, and 28-31 weeks.

Macroplasty is a deformity examination, which refers to the examination of the fetus in the womb to rule out malformations through some imaging techniques during pregnancy. In general, the best time to check for large deformities is 11-14 weeks, 22-24 weeks, and 28-31 weeks.

Nuchal translucency examination is performed at 11 to 14 weeks of gestation, which can be used to determine abnormalities in the early stages of the fetus; At 22-24 weeks of gestation, the overall structure of the fetus is basically fully developed, and ultrasonography can be performed to determine whether the fetus has structural abnormalities; At 28-31 weeks of pregnancy, through a re-examination of color ultrasound, it can be determined whether the fetus has congenital malformation symptoms such as cleft lip and palate, heart malformations, etc.

Although there is no need to have an empty stomach or hold urine like other examinations, there are still some precautions during the examination, and the pregnant woman can eat a small amount of food and drink some water to increase the frequency of fetal movements. Before the examination, you can walk around appropriately to relieve tension and avoid the impact of emotional tension on the examination results.

What is a large deformity?

Macroplasty refers to an examination of the fetus during pregnancy, when the gross development of the fetus's limbs, organs, and face is completed, and the fetus can be screened for malformations through the examination of macroplasty. The four-dimensional is actually a means of ultrasound, similar to a three-dimensional image, which can not only observe the development of the fetus's organs, but also see the face and limbs of the fetus.
