So how can a pregnant mother know that her baby is healthy? I think it can be judged from the following aspects.
I'm three and a half months pregnant. At this time, it is time to go to the hospital for the record, and all kinds of items should be checked for the record, including NT, early Tang Dynasty, blood routine and so on.
Among these projects, NT and early Tang are the most important inspections; First of all, NT examines the transparent layer behind the baby's neck with the help of B-ultrasound, so as to assess the risk rate of baby's deformity; If the NT value is less than 2.5, it proves that the baby is healthier.
Secondly, the concentrations of free fetal protein A (AFP) and human chorionic gonadotropin (β-hCG) in the blood of pregnant mothers were detected in the early Tang Dynasty, and then the risk of Down's syndrome was evaluated in combination with the age of pregnant mothers. If all the results show "low risk", it proves that the baby is relatively healthy.
There is also the most direct way to judge whether the fetal treasure is safe in the pregnant mother's stomach, and that is to listen to the fetal heart.
Under normal circumstances, the fetal heart rate of Taibao is normal between 1 10- 160. If the fetal heart rate of Taibao is lower or higher than this range, it is necessary to consider whether the umbilical cord is hypoxic around the neck.
During pregnancy, every time the pregnant mother has a prenatal examination, the doctor will listen to the fetal heart rate, and the pregnant mother can take this opportunity to understand the health status of Baobao; Then there is a problem, that is, pregnant mothers can't go to the hospital every week to listen to Taibao's fetal heart rate when the gestational age is not big.
It is suggested that pregnant mothers can buy a home fetal heart from a treasure, about 100 yuan. When free, pregnant mothers can listen to the fetal heart at home, which is convenient and can monitor the fetal heart at any time.
To sum up, in addition to the above two methods, pregnant mothers can also judge the health status of Taibao according to their usual pregnancy reactions. Although each pregnant mother's constitution is different, the degree of pregnancy reaction is also different, but if the pregnant mother had a serious pregnancy reaction before, such as morning sickness, she vomited until yesterday after pregnancy, and suddenly there was no morning sickness today. At this time, pregnant mothers should be vigilant and need to go to the hospital in time.
1, go directly to the hospital for B-ultrasound examination. If the doctor tells us that the fetal heart rate is normal and other development indicators are normal, the pregnant mother can rest assured.
The second way is early Down's screening, and it is generally recommended to check11-13 weeks and 6 days. The difference between this and nt is that blood is drawn for examination, and Nt is color ultrasound examination. It is usually recommended to refer to the comprehensive judgment of nt value. It is worth reminding that if the inspection indicates high risk, don't panic. You can continue to do amniocentesis according to the doctor's advice, subject to this result. Amniocentesis is usually the most accurate examination of Down's syndrome.
The third method is to go to the hospital to find a doctor for gynecological examination and listen to the fetal heart rate. If the fetal heart is normal, you can rest assured.
This method is especially suitable for pregnant mothers who have just done B-ultrasound, but are very worried about the health of the fetus in their bellies. When I was 90 days pregnant, I had a B-ultrasound. After a few days, I was a little worried, but I couldn't do B-ultrasound again. I went to the hospital to listen to the fetal heart. The doctor said that it was normal and I was relieved.
Of course, you can also buy a fetal heart and listen at home. This is more convenient.
With the development of medical instruments and technology, there are many detection methods for the fetus that we can't see during pregnancy to judge the development and health of the fetus. In the third and a half months of pregnancy, that is, 15 gestational week, that is, after the first trimester, the fetus has basically settled in the uterus. At this time, the fetal body structure has been formed. The fetus is about 10~ 12 cm and weighs about 40~50 grams. At this time, the hands and feet of the fetus can move flexibly, and some can grasp with their fingers or even eat their hands. You can also cross your eyes and frown on your face. Then where did you know about the development of the fetus? It was from the pregnancy test stick.
1: Color Doppler ultrasound examination is like a doctor's eyes and ears, which can help the doctor to see clearly the position of the placenta and judge whether it is stable. Hearing the heartbeat of the fetus is an important basis for the normal development of the fetus. Fetal heart rate is generally 120~ 160 beats/min.
2. Maternal check-up: Measure the uterine height, abdominal circumference and routine blood weight of pregnant mothers. And observe the size of the abdomen and whether there is edema in the limbs.
3. Down's screening: Down's screening should generally be conducted between15 and 20 weeks, mainly to check whether the fetus has dementia or mental retardation. As we all know, if children born in a family suffer from dementia and mental retardation, they need the care of their families all their lives, which is a heavy economic burden for the family and will also bring great mental stress to the family. This inspection is carried out in two steps. Firstly, the blood of pregnant mothers was taken, and the concentrations of AFP and HCG in serum were checked, and the possibility of Down syndrome was judged by combining the age and expected date of delivery of pregnant mothers. If the coefficient is high, further confirmation is needed.
Three and a half months pregnant, that is, 13 weeks, the fetus is 8 cm long and weighs 20 grams. Fetal eyes are obvious, ears have been formed, mouth can be opened, and neck can support fetal head. Fetuses are more and more like babies.
If pregnant women want to know whether the fetus is healthy, they can judge the health of the fetus through some tests.
1. Color Doppler ultrasound.
Pregnancy is 9- 13 weeks, which is the best time to do NT color ultrasound. It measures the thickness of the transparent layer of the fetal neck to judge the risk of Down syndrome.
If the thickness of the transparent layer of the fetal neck is less than 3 mm, then the fetus is low-risk health.
If the NT value of the fetus is greater than 3 mm, especially greater than 6 mm, the risk of Down syndrome in the fetus is higher.
2. Early screening of Down syndrome.
At 9- 13 weeks of pregnancy, pregnant women can be screened at the beginning of Tang dynasty, which is also one of the means to screen down syndrome. If the test results show that the risk is low, then the risk of fetal Down syndrome is very small. If the test shows high risk, then pregnant women need amniocentesis to rule out the risk of fetal Down syndrome.
Down syndrome has mental retardation and multiple organ malformations. If the fetus is down syndrome, it means that the fetus is unhealthy.
3.b-ultrasound examination.
If the pregnant woman does not have nt color Doppler ultrasound, then 13 weeks or so, a B-ultrasound examination is needed, and the doctor will confirm that the pregnant woman is pregnant in utero. If you see the fetal heart embryo and the fetal heart beating, it proves that the baby is healthy.
If it is ectopic pregnancy, ectopic pregnancy or hydatidiform mole, then even if the fetus develops well, the pregnant woman can't continue her pregnancy.
As long as you check regularly and follow the doctor's advice, you can relax without any problems. Three and a half months should be nt and Tang Sie?
Regular physical examination, pay attention to diet and rest habits.
