Is the B-ultrasound that is often done during pregnancy really necessary? Four kinds of B-ultrasound examinations pregnant mothers can't miss no matter how busy they are

For pregnant mothers, pregnancy test is an essential part of the pregnancy process, and some inspections even need to be tested once a week. In this process, B-ultrasound examination is a problem that many mothers will encounter.

B-ultrasound is one of the ultrasound examinations, which can observe the shape, organs, movements, etc. of the fetus in the pregnant belly, and can monitor whether the development of the fetus is healthy.

After all, pregnant mothers are not professional doctors and do not understand the professional medical knowledge in B-ultrasounds. Faced with the B-ultrasound orders that doctors often issue, they have a series of questions: How many times of B-ultrasounds should I have to do in October of pregnancy? When to do it? Many people say that it is not good to do too much B-ultrasound. Is it harmful to the body?

Is it really harmful to do B-ultrasound during pregnancy?

Scientific proof: B-ultrasound is ultrasonic conduction, there is no ionizing radiation and electromagnetic radiation, this kind of sound wave does not pose a hazard to human health.

Maybe many pregnant mothers have heard others say that B-ultrasound can be done less often, and it will have side effects on the body of the pregnant mother and the fetus. However, as far as the current inspection is concerned, the sound intensity and irradiation time used in the ultrasound examination performed by pregnant mothers have not been proven to be harmful to the body. Therefore, the B-ultrasound used in the obstetrics department of the hospital is safe, and the pregnant mother can check it with confidence under the advice of the doctor.

Moreover, it is very necessary to do B-ultrasound during pregnancy. The main purpose of B-ultrasound during pregnancy is to clearly observe the development of the fetus, monitor whether the fetal heart rate is normal, the development of the placenta, the amount of amniotic fluid, and the growth of limbs. In addition, it is also possible to see whether the fetus has special symptoms such as umbilical cord around the neck and developmental deformities. If there are, abnormal conditions can be captured through B-ultrasound examination, and the unfortunate condition of the fetus and whether there are defects can be found in time, so that remedial measures can be taken in time.

Therefore, B-ultrasound examination during pregnancy is not only harmless to the body, but also a very necessary pregnancy examination.

How many times should I do ultrasound during pregnancy? When to do it? doing what?

Generally speaking, healthy pregnant mothers need to perform B-ultrasound examinations about four times during pregnancy. However, some pregnant mothers have special circumstances in their physical conditions and fetal development. Doctors will recommend multiple examinations as appropriate.

1. The first B-ultrasound examination: around the 7th week of pregnancy

Mainly check whether the fetus is implanted and the basic development. At this time, it is normal that the fertilized egg has implanted into the endometrium. If it is found that the fertilized egg implants and develops in parts other than the uterus, such as the fallopian tube, ovary, and peritoneum, it is an ectopic pregnancy, and timely measures should not be ignored.

2. The second B-ultrasound examination: around the 11th to 14th week of pregnancy

This B-ultrasound examination is mainly NT examination, the full name of which is the cervical translucency scan examination. This examination method can be used to do "Tang screening", that is, to detect whether there is a fetus with Down syndrome in the pregnant belly. B-ultrasound examination in this period is very necessary. If an unexpected situation is found, it can be prevented and improved in time, so as to avoid greater adverse consequences in the future.

3. The third B-ultrasound examination: around the 20th to 24th week of pregnancy

This is a very important test to check how the fetus is developing? Are there obvious deformities? Is placental amniotic fluid normal? At this stage, the fetus is basically mature, and the limbs and internal organs have been formed.

This B-ultrasound examination can clearly see the outline of the fetus, so it is possible to check whether there is any abnormality from the appearance and development. This time, the four-dimensional color Doppler ultrasound is generally used to do the malformation examination.

4. The fourth ultrasound examination: around the 28th to 32nd week of pregnancy

This B-ultrasound examination was carried out to further check the abnormal discharge, and also focused on checking the amount of amniotic fluid, the maturity of the placenta, and the fetal position. At this time, the fetal development is basically mature, and the B-ultrasound examination in the third trimester is mainly to evaluate the weight and health of the fetus, and discuss with the pregnant mother about the appropriate production method.
