What are the signs of fetal abnormalities?

There are more than a dozen examinations during pregnancy, and each prenatal examination affects the heart of the pregnant woman, for fear that the doctor will say that the development of the fetus is abnormal. Among these examinations, one of the most important tests is the large deformity. Before the major deformity examination, the pregnant woman begins to get nervous.

What they are even more afraid of is that if the fetus is found to be abnormal, how to choose, and it is really difficult to make a decision whether to stay or not. In fact, if the pregnant woman can know this, even if the result of the large deformity is not good, the pregnant woman will not be confused and can make a better choice.

What is the big row deformity?

In addition to checking the routine amniotic fluid and placenta, and whether the fetus's development is up to standard, the fetus's organs and internal organs will be examined in detail. The main reason is to understand whether the fetus has major structural defects, so it is also called "large deformity". However, the specific examination items will vary from hospital to hospital, so pregnant women should be aware of it.

When is the large row deformity done?

The best time to check for large deformities is 20-24 weeks of pregnancy, and there are two main reasons for setting this time. One is that if you examine it during this period, you can find most cases of structural abnormalities in the fetus. If it is too early, the fetus is still small and the organs are not fully developed, so the corresponding abnormalities cannot be well found.

If it is too late, the fetus occupies a large space in the uterus, and some parts are easily blocked, resulting in inaccurate test results. The other is that if the pregnancy is terminated late, but the fetus is found to be abnormal, it is difficult for the pregnant woman to decide whether to terminate the pregnancy. This is a blow to the pregnant woman, both physically and psychologically, and somewhat cruel.

What is the detection rate of large deformity?

This is a concern for many pregnant women, and in fact, pregnant women should not expect too much. In fact, there are many factors that affect each examination, such as the thickness of the pregnant woman's abdominal fat, the amount of amniotic fluid, the degree of cooperation of the fetus, and the doctor's experience. Generally speaking, the average detection rate of large deformities is about 80%.

Therefore, it should be understood that it is the doctor's responsibility for pregnant women not to find fetal malformations and miss the diagnosis.

There are no signs of fetal abnormalities and must be checked by ultrasound. For example, if there is an abnormality, the baby's head circumference, femur length, and the length of the growth of the top of both necks can be detected.

There are signs of multiple aspects. For example, facial development, some may have an underdeveloped nose and cleft lip and palate. Then there is poor heart development, such as atrial deficiency.

For example, through some professional examinations in hospitals, you can see some of the baby's face, heart, and some body organs, whether there are any malformations, and at the same time, pregnant women should maintain a good living habits, pay attention to rest, and must have balanced nutrition.

There are no clear signs. Large-scale deformity examination is a four-dimensional color ultrasound examination of the fetus, which is generally performed between 20-28 weeks of pregnancy. Four-dimensional color ultrasound examination is a kind of real-time dynamic image, which can observe the development of fetal body surface and internal organs and the activity of the fetus in the uterine cavity under dynamic conditions, which is helpful to find fetal body surface development malformations and malformations of internal organs, and has relatively high diagnostic value for fetal limb abnormalities and fetal heart development abnormalities.

Abnormalities in the examination of large deformities can be accurately and clearly described on the images of the 4D color ultrasound examination. There are no clear aura symptoms before the tests are done.

There will be no signs of fetal abnormality, if the malformed fetus is developing normally, so only through three-dimensional color ultrasound to observe the baby's development in an all-round way.

Be sure to listen to the doctor's advice, if the doctor advises you not to have this child, then it is better not to stay, otherwise the child's malformation rate is very high.

Mothers find abnormalities when examining the macrofilament, and most mothers confirm that there is no problem after further examination. Therefore, pregnant women should not cry first, because excessive sadness and endocrine disorders can affect the fetus, affecting the frequent movement and growth and development of the fetus. Indeed, some cases can only be diagnosed after retesting, such as fetal lateral ventricular enlargement, separation of both renal pelvises, and may return to normal at the next retest.

Therefore, pregnant women only need to be patient and wait for the results of the follow-up test.

Treat it according to the doctor's advice as needed, be sure to adjust your mentality, don't put too much pressure on yourself, and if it is recommended to terminate the pregnancy, you can only choose to terminate it.

I believe that many expectant mothers have heard that the old drivers of pregnant mothers have mentioned that large deformity is a very important part of the prenatal examination, and even determines the departure and stay of our fetus, but what should pregnant mothers do if there is an abnormality in the large deformity examination?

What is a large deformity?

It is an examination that uses three-dimensional or four-dimensional color ultrasound to see the physical development of the fetus and then rule out fetal malformations.

This test can reflect the development of the fetus's face and various organs by means of imaging. It is used for the detection and screening of fetal malformations, and provides an accurate scientific basis for the early diagnosis of fetal congenital body surface malformations and congenital complex malformations. At the same time, it can clearly show fetal polycystic kidney disease, renal dysplasia and other diseases, which is of great value for judging fetal congenital heart disease.

The best time for large deformity.

Generally, at about 20-28 weeks, color ultrasound prenatal deformity can be done. The reason why it is done at this time is mainly because the main purpose of the screening is to check whether the fetus has major structural defects through B-ultrasound.

If you do it too early, the fetus is still relatively small, and the corresponding organs have not yet developed well, so no abnormalities can be detected.

Of course, it can't be too late, if it is more than 28 weeks, it will be done in 7 months of pregnancy, although the fetus has grown larger, but the space for activity is relatively small, and some parts of the body may be occluded, which is not easy to observe. Therefore, the best time to do it is at 20 weeks for a major deformity examination. ”

Do I need to fasting or hold urine during the large deformity examination?

When doing a major deformity examination, it is not necessary for the pregnant woman to have an empty stomach or hold urine, as long as she goes to the hospital within the specified time. Half an hour before the deformity test, you can also eat something and drink some water to increase the fetal movement so that the doctor can see more clearly.

Also note that before going to the hospital, wear clothes that are separate from the top and bottom to facilitate the examination.

What should I do if there is a large deformity?

In this case, don't worry, the sky hasn't fallen yet. If it cannot be clearly displayed in the ultrasound examination due to the influence of fetal position, amniotic fluid, maternal and other factors, the prenatal examination report will explain which structures show deficiency, if you find this situation, you can consult the doctor, you can do it again.

If some areas are not good, they can be repeated in 2 to 4 weeks.

Because there are many kinds of prenatal ultrasound images of fetal malformations, and the images of the same malformation may be different at different stages of pregnancy, coupled with the wide variety of prenatal ultrasound images of the instrument, and the images of the same malformation may also be different at different stages of pregnancy, coupled with the limitations of the instrument and the influencing factors of the fetus and maternity, missed diagnosis is often unavoidable.

Pregnant mothers can hold on to their normal hearts. Maybe the next review will be normal, which is a common thing.

Throughout the pregnancy, the mother of the first pregnancy will have a lot of questions, first of all, don't keep it in your heart, when you encounter doubts and worries, you can consult the moon at any time, and wish your pig baby healthy and cute.

There are no signs of fetal abnormality, and the pregnant mother can't feel it. The child's abnormalities are usually in the limbs, lips, internal organs, and nervous system, which can only be detected by regular prenatal checkups.

Anencephaly, hydrocephalus, spina bifida, limb deformities, and structural abnormalities of organs can be found in large row deformities. For example, the loss of growth, lack of oxygen, etc., these abnormalities can be felt as abdominal pain, bleeding, loss of pregnancy reactions, and sudden increase and sudden decrease in fetal movements.

The first point is that there will be an abnormal fetal heart rate in this fetus, so you must pay attention to it, the second point is that there is a possibility that there will be an abnormality in a certain part of the fetus, and the third point is that you will feel uncomfortable in your stomach, and you should go to the hospital for examination immediately at this time?
