Antenatal examination of the baby's future

Modern methods of research allowDetermine the state of his health at the chromosomal level - even in the mother's womb. What are the advantages of prenatal diagnosis, does it imply risks for the health of the mother and the unborn child? An antenatal study of a future baby will allow mom to feel confident that her baby is healthy.

Prenatal screening of pregnant women

Any family, expecting a child, is in troubleAnd doubts. To dispel them, to reassure future parents, prenatal screening is possible in time and consciously conducted. What it is? For doctors, the word "prenatal" is denoted by the term "prenatal". "Screening" comes from English to screen and translates as "sifting". This diagnostic method has been used in the world for the last 25 years. Its essence is to select from the number of pregnant women exactly those who need a more thorough prenatal survey. At the chromosome level, the method makes it possible to clarify: what is the state of health of your unborn baby? Screening is primarily aimed at preventing the most common congenital pathologies: Down's disease, neural tube defects (hydrocephalus, spinal cord hernia, etc.), anterior abdominal wall injuries, congenital heart diseases, kidneys, and some other less frequent abnormalities The fetus. Why does Down's disease come first in this list?

Because among newborns
It occurs most often, its frequency in Ukraine and Russia is one case for 750 - 800 births. An antenatal examination of the baby's future helps fight the disease at an early stage.

Any pregnant woman who cares about the question: Is my child healthy? Pregnant, deliberately rejecting the intervention in the body - and your own and the child, or those who will not interrupt the pregnancy, even if there are serious abnormalities in the health of the baby.

Most violations in the development of an unborn child can be detected only after 11 weeks of pregnancy.

When screening
In the first trimester (up to 14 weeks), the diagnostic accuracy is approximately 90%, and in the second (15-16 weeks) - 60%.

To fully verify the presence of chromosomalFailure in the child, it is necessary to immediately carry out an invasive procedure (methods for more thorough diagnosis, involving medical intervention in the mother and child), even without screening results. The normal result is not a 100% guarantee for the birth of a healthy baby. Why do you need a computer calculation?

Evaluation of the results of antenatal careFuture baby and screening without computer calculation of the risk of childbirth with chromosomal abnormalities is not informative. Unfortunately, some patients take tests in laboratories and come to the doctor with the results without calculating the risk. In such a situation, it is impossible to assess whether a mother is at risk.

And it's not dangerous?

Methods of screening and antenatal researchThe future of the baby is absolutely safe research. Screening is carried out at different times of pregnancy. It has now been proven that prenatal screening for chromosomal diseases in the first trimester of pregnancy is most effective, from 11 to 14 weeks. By the way, the gestational age should be assessed not from the expected date of conception, but from the first day of the last month. All screening indicators are entered into a special computer program, which also includes the age of the woman, her weight, the history of previous pregnancies and childbirth. After this, the computer program calculates the individual risk of having a child with chromosomal abnormalities. And if it is high, such doctors can recommend more accurate methods for determining the chromosome set of the fetus: a chorionic villus biopsy, an amniocentesis with amniotic fluid and cordocentesis (in this case, examine the baby's cord blood).

What method of diagnosis and prenatal study of a future baby to choose?

Study of villi chorion (future placenta). It is carried out from 10 weeks of pregnancy. Allows to determine the presence / absence of disease in the early stages. High risk of abortion (2 - 3%). Patients with a high risk of having a child with chromosomal abnormalities.

Diagnostic Amniocentesis

It is carried out at 16-17 weeks of pregnancy. Fetal cells that are "floating" in the amniotic fluid are examined. The procedure is the safest for maintaining a pregnancy, the risk of abortion does not exceed 0.2%. A sufficiently long gestation period. It takes 2-3 weeks to get the result.

Patients with an average risk of having a child with chromosomal abnormalities.

Who is recommended cordocentesis

Fetal blood test. It is held not earlier than 20 weeks. Efficiency of obtaining the result is optimal even in late pregnancy. A high risk of complications, therefore, is rarely used. Mothers with a high risk of having a child with chromosomal abnormalities.

How dangerous are the invasive interventions and prenatal study of the future baby for mom and baby?

Numerous studies confirmThe safety of these procedures, subject to the high qualification of the doctor and the absence of contraindications at the time of the study. If during pregnancy there are complications, the doctor refuses to carry out manipulations.
