How many months can I check my baby's health? Pregnancy needs prenatal examination, in which B-ultrasound is a very important part.
What is the B-ultrasound examination?
B-ultrasound can not only locate placenta and measure amniotic fluid, but also make early diagnosis of singleton and multiple births, fetal development, malformation and hydatidiform mole.
The difference between color ultrasound and B ultrasound
1, color Doppler ultrasound is actually a kind of high-definition black-and-white B-ultrasound plus color Doppler, which not only has the advantages of two-dimensional ultrasonic structural images, but also provides rich hemodynamic information. Ordinary B-ultrasound images are black and white photos, color B-ultrasound images are color photos, and 3D B-ultrasound images are VCRs taken by cameras. Four-dimensional B-ultrasound adds time dimension parameters to three-dimensional B-ultrasound, which can observe the dynamic moving images of the fetus in real time. Ordinary B-ultrasound and color ultrasound only see one plane, while three-dimensional B-ultrasound and four-dimensional B-ultrasound see three-dimensional images of the fetus, which can be seen from front to back, from left to right and from top to bottom, which is more comprehensive, true and clear.
Generally speaking, the radiation of color ultrasound is greater than that of black and white ultrasound. In the early pregnancy, doctors usually choose to give pregnant women a black-and-white B-ultrasound to determine whether the fetus is pregnant. In the second trimester, in order to observe the blood flow of the fetus, whether there is any big abnormality in the fetus and find the abnormality of the fetus in time, color Doppler ultrasound will be done.
Precautions for prenatal examination 1. General check-up of pregnancy test: this is essential in pregnancy test, and pregnant women need to have a comprehensive check-up in 4-5 months of pregnancy. Among them, routine examinations include blood routine and blood type, urine routine, liver and kidney function, fasting blood sugar, AIDS, syphilis and other infectious diseases screening, and various hepatitis viruses screening, and some special examinations are done as appropriate. Among them, the general examination should pay special attention to the slight increase of blood pressure during pregnancy, but it should not exceed the basal blood pressure of 140/90mmHg or 30/15 mmhg; Pay attention to whether there is excessive weight gain and edema.
2. Abdominal examination during pregnancy: observe the shape, size and edema of the abdomen, and measure the abdominal circumference and uterine height; Touch the fetal position, and the abnormal fetal position over 30 weeks of pregnancy should be corrected actively; The fetal heart rate was 120 ~ 160 beats/min. Pelvic measurements were taken at 7 months of pregnancy to estimate the delivery mode of the fetus.
3. Down's screening during pregnancy: Pregnant women can have Down's screening in the hospital during the week of pregnancy 15- 18. During screening, maternal peripheral blood was taken to detect whether its biochemical indexes were abnormal; If necessary, pregnant women can continue to undergo amniocentesis for further examination; Then analyze and judge the risk of down syndrome in fetus; Pregnant women can decide whether to terminate their pregnancy through informed choice.
4. Pregnancy examination Four-dimensional color Doppler ultrasound: Generally, abnormal screening is performed at 22-26 weeks of pregnancy, and the maturity of fetus and placenta is checked by full-term ordinary B-ultrasound. If there are abnormalities during pregnancy, you can review them as appropriate.
Matters needing attention during pregnancy
1, smoking and drinking are absolutely forbidden during pregnancy.
First of all, you should know how much harm smoking and drinking will bring to yourself, which will make your body very unhealthy. There is also the fact that alcohol can cause devastating damage to the fetus in the womb. If you drink and smoke regularly, it will directly affect the development of the fetus in the abdomen, and even lead to fetal malformation in the abdomen in severe cases. Therefore, during pregnancy, you must protect your baby. Smoking and drinking are absolutely forbidden, even for men. Secondhand smoke is not allowed.
2. Don't make up often during pregnancy.
Now that you are pregnant, you should stay at home without makeup, even if you go out and put on a little light makeup. If you wear makeup often, you will find that your skin will be very allergic, because your whole body is very fragile during pregnancy. Even if you wear makeup, you should buy some very good cosmetics to protect yourself. Try not to wear makeup at home. If you use very inferior cosmetics, it will directly affect the fetus in your stomach. Don't think that there is nothing wrong with the fetus on your face, but always pay attention.
3, often take a bath during pregnancy.
You can imagine how comfortable it is to take a bath. After taking a shower, you will feel very comfortable and make yourself feel good. But if you are comfortable and your daughter is comfortable, the baby in your belly will not be so small. If you take a bath often, it will make your stomach hot, which will lead to the baby's lack of oxygen. It is conceivable that the lack of oxygen in the baby's stomach is terrible. That is, frequent bathing can cause vaginal infection, and the risk index is almost full. You must take a bath during pregnancy.
You must exercise regularly during pregnancy.
I believe that during pregnancy, the body will be very tired, which will lead to pregnant women becoming more and more lazy and unable to exercise. At this time, you must encourage yourself to exercise more. Of course, you can't do very large-scale exercise, which will affect the fetus in your stomach. You can do some small exercises to make your body healthier. If you are in labor, your body will have a good baby more easily.
5. Cut off all electronic products.
Maybe during pregnancy, you will be bored. If you stay at home every day and just want to do something, but there is nothing you can do, you can only sit in bed and play with your mobile phone. But you must remember that electronic products are radioactive, and radiation is a terrible thing for the fetus in the womb. If it is serious, it will affect your child's deformity, so don't play with your mobile phone often.
