How often you can do ultrasound during pregnancy, if ultrasound is harmful to the fetus?
Parents are worried about the health of your future baby, with concern applies to any research during pregnancy: is it harmful ultrasound during pregnancy, there are no contraindications, is it dangerous its influence on the embryo, on what terms should be, how many times, for what, what are the long term effects for a child? These questions are quite natural. Ultrasound diagnostics for the study of fetal anomalies practiced since 1958. Although, the harm of ultrasound in pregnancy is not proven, is still conducted the search for data to confirm this fact. Fetal ultrasound is the most important screening method of research, as it possesses great potential for diagnosis and can be performed at any time if there are indications of a doctor.
Why do the ultrasound, if everything is OK?
How it is still known that fetal ultrasound is not dangerous for the unborn child both early and later stages, but nevertheless, the doctors are giving him only according to clinical indications. This question has long been discussed. There are two terms in which the study of the fetus is most useful and gives most information. It is such times as:
There is no point in the procedure at the first treatment of the patient with suspected pregnancy (unless clinical indications), although many doctors prescribe the procedure. In the early stages it has a low clinical information, and must be held from 18 to 22 weeks of pregnancy to obtain reliable results.
The advantages of ultrasound as a method of monitoring and controlling pregnancy
There is no other technique which can detect as many abnormalities and pathologies of pregnancy how many ultrasound reveals. It also has a low cost, its negative impact on the fetus has not been proven, which allows to examine, without exception, all pregnant women under the free medicine. In addition, an ultrasound in the first trimester detects problems such as:
- Missed miscarriage or ectopic pregnancy.
- Major fetal anomalies.
- Signs that allow to detect the defects at an early period x of the unborn child.
As for the second and third trimester of pregnancy all the attention of specialists focused on the detection of fetal malformations, disturbances of growth, the diagnosis of the pathology of the amniotic fluid, placenta and umbilical cord.
Stages of ultrasound screening of their content
In Russia, according to the national manual of obstetrics is carried out three times.
The purpose of the ultrasound of the first trimester (held from 10 to 14 weeks of pregnancy): the definition of nuchal thickness (NT) embryos.
The purpose of the ultrasound examination in the second trimester (between 20 and 24 weeks): determination of gestational age, establishing the probable date of delivery, detect multiple pregnancy, and exclude fetal malformations.
The purpose of the ultrasound examination in the third trimester (between 30 and 34 weeks): assessment of fetal growth, the detection of defects manifestation in this term, malformations of the placenta and amniotic fluid.
The danger for an ultrasound of the embryo: does it exist?
Ultrasound in obstetrics used since 1958, but so far there are no studies that could prove or disprove the harm of ultrasound during pregnancy. Some researchers argue that for the child in the womb is dangerous not so much ultrasonic radiation how heat waves from the sensor itself. This is due to damage of cells in the case of heating them. Therefore, most strongly affected the brain of the child. But such a study is given in pregnancy to the case when the risk (if it still exists) is justified. Procedure in the early stages to check for abnormalities in fetal development, defects, danger to the mother and other negative scenarios that help doctors to take timely action to birth a healthy child.
Another question is how often you can do ultrasound during pregnancy. The answer is simple: as much as they tell a watching you obstetrician-gynecologist. Specialist assesses risks and determines the optimum amount of research. Long-term effects from the influence of ultrasound is not so terrible, as loss and unresolved issue in relation to mother or child. Women with normally developing fetus, according to the national leadership need to pass the three required examinations (see above).
The problem of modernity in relation to such studies is the uncontrolled use of ultrasonic installations. For example, to get photos or video of the fetus in the womb. This is the so-called 3D three-dimensional study. The point here is not, what is the impact of ultrasound on the baby, and how much time a woman spends on 3D and 4D studies. Instead of 10-15 minutes for the classical survey on three-dimensional and four-dimensional, a woman spends up to 45 minutes. And it can be dangerous. In some countries this issue is already trying to regulate the control authority but in Russia there are no regulations so to do or not to do the us parents decide.
