Prenatal screenings cause a lot of conflicting opinions and feedback. Someone is convinced of their necessity; others are convinced of their complete inexpediency. What kind of research is this, and should all pregnant women really take them? To understand this issue, let's weigh the pros and cons and separate the existing myths from the objective data of scientific medicine.
The argument "against" number 1: ultrasound harm the baby
There is a fairly common opinion that Pregnancy Ultrasound negatively affects the nervous system of a child, annoys him - during the examination, children often try to hide from the apparatus, cover their heads with hands. Therefore, children whose mothers regularly performed ultrasound during pregnancy are more restless than babies whose mothers have refused ultrasound diagnosis. Is it really?
According to doctors, ultrasound cannot cause the baby absolutely no harm - modern equipment is absolutely safe. Therefore, official medicine insists that absolutely all pregnant women should undergo an ultrasound. Indeed, the timely diagnosis allows, firstly, to see the full picture of the course of pregnancy, and secondly, if necessary, to correct certain problems.
Especially important are the data obtained on ultrasound of the first prenatal screening (at 11-13 weeks of pregnancy). During this period during the study:
- The number of embryos in the uterus and their viability are determined;
- Put a more accurate period of pregnancy;
- Gross defects are excluded;
- Determines the thickness of the collar space - (that is, the amount of subcutaneous fluid on the back of the child's neck is measured - in normal TVP should not exceed 2.7 mm);
- The presence or absence of the nasal bone is investigated.
The argument "against" No. 2: a biochemical blood test gives an unreliable result
Many mothers are sure that it is impossible to make at least some reliable conclusions on one analysis- too many factors can affect the result. And, in part, they are really right. However, it is necessary to study the analysis process more closely in order to understand on what basis the doctor makes a conclusion. The second screening takes place at 18-21 weeks of pregnancy. This study includes a "triple" or "quadruple test. "Everything happens the same way as in the first trimester- the woman again takes a blood test. Only in this case, the results of the analysis are used to determine not two, but three (or, respectively, four) indicators.
The argument "against" No. 3: "I have good heredity- I do not need screenings."
Some mothers do not see the point of going through screenings - all relatives are healthy, what problems could there be? Indeed, there are certain groups of women who are primarily recommended to undergo Pregnancy Ultrasound to identify possible pathologies in the development of a child. These are women over 35–40 years old (since after this age, the risk of developing abnormalities in a child increases several times) and expectant mothers with certain diseases (for example, diabetes).
