"B-ultrasound" can know the fetal problems in advance. Xiao Chun and her husband were pregnant with a child after a year of marriage. In order to give the baby a better growth environment, the husband also works harder. Because her husband is busy at work, Xiao Chun often needs a person to go to the hospital for examination.
After two B-ultrasound examinations, Xiao Chun felt that the baby in her belly was developing normally, so she became slack. She felt that her body was very healthy, so it was no problem not to do B-ultrasound, and at the same time she could save money for her family.
On the day of delivery, the family is very much looking forward to the birth of the child. However, the news that the child was diagnosed as "microcephaly" after birth also plunged the whole family into heavy sadness. When learning that Xiao Chun had only done B-ultrasound twice during her pregnancy, the doctor sighed and said, "B-ultrasound can check whether the fetus is abnormal to a certain extent. It is difficult to know the possible problems of the fetus in advance if she misses B-ultrasound."
How many times does mother need to do B-ultrasound during pregnancy? In a scientific parenting program for infants and young children, Wu Shaowen, deputy director of the Department of Obstetrics and Gynecology of Beijing Maternity Hospital, said that pregnant mothers should have six B-ultrasound examinations during pregnancy, and these stages should not be missed no matter how busy they are.
Pregnancy 6- 1 week
The first ultrasound examination was performed when Ma Bao was 6- 10 weeks pregnant. The main purpose of this examination is to exclude ectopic pregnancy, monitor whether the child has fetal heart rate and accurately calculate the number of weeks of pregnancy, and also check whether the pregnant mother has gynecological diseases.
2. Pregnancy is 1 1- 14 weeks.
The second ultrasound was at 1 1- 14 weeks of pregnancy. The main purpose of doing B-ultrasound at this stage is to judge whether the child's chromosome is abnormal, and also to preliminarily screen the fetal development structure.
3. 20-24 weeks pregnant
The third B-ultrasound is during the 29-24 weeks of pregnancy, and the B-ultrasound at this stage is also called "big rejection". As the name implies, it is to exclude deformity from the child's development structure.
4. 28-32 weeks pregnant
The fourth B-ultrasound is at 28-32 weeks of pregnancy, and this stage is called "small ovulation". At this time, the development of fetal organs is more perfect, so this process is also a further understanding of whether the fetus is deformed.
5, 34-36 weeks pregnant
In the second and third trimester of pregnancy, that is, 34-36 weeks, pregnant mothers should have the fifth B-ultrasound. The purpose of this examination is to know whether the growth of the fetus has reached its due level. At this time, if the child is abnormally developed, necessary remedies can also be made.
6. After 37 weeks of pregnancy
The last B-ultrasound should be after 37 weeks of pregnancy. This time, it is a prenatal assessment, which is to judge whether the amniotic fluid is sufficient and the position and size of the fetus, so as to prepare for the next delivery.
Besides B-ultrasound, these tests are also essential.
Down's screening is a common and necessary examination during pregnancy, and some fetuses have slight abnormalities, which may be difficult to detect by B-ultrasound. The purpose of this test is to screen chromosomes and reduce the probability of birth of children with Down syndrome.
3. Interventional prenatal diagnosis
In addition to preventing fetal malformation, whether the fetus has congenital genetic diseases is also a problem that must be discovered and prevented as soon as possible. Interventional prenatal diagnosis is to diagnose fetal chromosomes and genes through various techniques, and to exclude the situation that the fetus has genetic diseases.
It is a long process from successful conception to delivery. Every mother who wants her child to come to her home healthily needs to be careful in the process of "pregnancy in October", and the necessary examinations during pregnancy must not be missed.
