For many elderly people, they all know that pregnant women contain too many unstable factors in the first three months of pregnancy. After three months of pregnancy, the pregnant woman's body will gradually stabilize, and there will not be too much problem at this time. Of course, if you can't wait, pregnant women can also observe the data on the B ultrasound on their own.
Ms. Zhang is now two months pregnant, and she sees her stomach slightly bulging, in fact, she is also looking forward to the moment when the baby is born. After all, Ms. Zhang is giving birth to a child for the first time, and she still has unlimited expectations in her heart. At this time, in order to further understand the changes in the child, Ms. Zhang did a B ultrasound examination in the first three months of pregnancy.
After waiting for a while, the results of the examination came out. Just seeing this test list, Ms. Zhang is a little confused, what exactly is written on it? Because Ms. Zhang didn't know much about this aspect, she had no way of understanding what kind of situation the child in her belly was in. Until this time, the doctor next to him pointed to the test list above, and then said: "The child is fine, it's okay." ”
Ms. Zhang was a little curious, how did this come about? At this time, the doctor smiled and said: "Your NT examination indicators are very good, and the child will certainly not have any problems." After listening to the doctor's words, Ms. Zhang put her heart into her stomach. As long as my own child does not have too much of a problem, after all, Ms. Zhang is still very worried about the child's condition.
In fact, this is a very simple example, for pregnant women in the first three months of pregnancy, it is definitely necessary to do a series of tests. Of course, we can also understand the condition of the child in the stomach through these tests. Especially in the B ultrasound, it is easy to see the secrets of the fetus, we just need to pay attention to it in the usual time, these data we can usually understand.
In the first three months of pregnancy, the B ultrasound contains two big data, which can see the secrets of the fetus
If you really want to understand this matter, then you can first look at the length of the fetus's head and buttocks. Generally speaking, before the child is three months pregnant, the head is still relatively small, usually around five centimeters. Moreover, the fetus in the mother's stomach is presented in a state of curling up, which will also bring certain difficulties to the measurement of double top diameter and femur length, so at this time will choose to measure the length of the child's buttocks.
Here, there is also a noun term called CRL. The length of the head and hips is mainly to observe the distance between the child's head and hips, and through this practice, the gestational age of the fetus can be calculated. That is, CRL + 6.5, if the length of the child's head and hips is 3cm, it means that the gestational week is 3 + 6.5 = 9.5 weeks.
Then there is another piece of data that is important, which is the so-called NT examination. In general, this test is mainly to see if the child is a person with Down syndrome. The NT examination mainly looks at the size of the transparent layer space behind the child's neck, and the size of the normal fluid accumulation will protect the child's brain. For the standard of NT value, the domestic has always been 2.5mm.
In other words, if it is less than this value, then the child's situation will become very good and healthy. If the value is relatively high, then it is very likely to have Down syndrome, and there will be other complications, such as heart abnormalities, or intestinal malformations, which are often fatal for children. Of course, even if it is high, there is no need to worry too much, sometimes it does not last too long.
Other data on the B-super-list can also be understood
By the time the baby in the belly reaches three months, their heart is already functioning. Therefore, when checking the ultrasound B, the heart rate can be detected. It's just that at this time the fetal heart rate is certainly not very stable, sometimes reaching one hundred and eighty beats a minute. Of course, this is not too serious a problem, as long as the fetus grows to a certain age, the heart rate will become normal.
Then there is the amniotic fluid indicator, if the fetus wants to survive, it must be inseparable from the amniotic fluid. The amniotic fluid in the stomach of pregnant women is almost 30ml, and at this time, ultrasound B can detect the depth of amniotic fluid. At this time, the depth is grown from two to eight centimeters, and if the value is incorrect, then there is certainly no benefit to the child in the belly, and the situation of the child in the belly will become very bad.
So when the child is less than three months old, we can completely look at these B-super values to determine the child's health problems. If something goes wrong, then we need to be cautious. Of course, some problems are not serious problems, so we don't need to panic too much, just wait quietly for the child to grow, and then the child will come to us in good health.
