Amniopunktsiey or called amniocentesis sampling (small amount) amniotic fluid.This fence is carried out under the constant supervision of a doctor using ultrasound machine.First, the doctor determines the position of the child in the womb.Then, through a puncture in the abdomen and uterine wall into the amniotic fluid is introduced into a thin needle through which recruited 10 to 20 milliliters of amniotic fluid.
basic fact for this study is that the cells in the genetic sense of the fluid are the same as the cells in the fetus.Derived from the amniotic fluid cell material is isolated and grown, and then subjected to careful scrutiny.
In addition, this procedure provides invaluable assistance in the identification of metabolic disorders, which is achieved by determining the levels of chemical substances in the amniotic fluid.This study is performed in the period from the sixteenth to the twentieth week of pregnancy.
During the procedure you need to sit comfortably on the bed.Your spouse (if de
risk of spontaneous abortion as a result of the procedure amniocentesis is about 1.5%.But even with such a low probability of miscarriage, this study should not be carried out without any serious medical condition!
When amniocentesis performed?
Amniocentesis (amniopunktsiya), as well as any other operational (invasive) methods of antenatal (prenatal) diagnostics performed exclusively in the presence of strict indications.This fact is explained by the fact that the presence of the gene in the fetus, chromosomal and metabolic diseases - a rare phenomenon.Direction to carry out such a test may be granted only if there is good reasons, for example because of the age of the woman over thirty-five years, or the presence of genetic disease in the family, which can inherit your child.In most cases, the study is carried out to exclude the presence of fetal Down syndrome, as well as the suspected presence of congenital defects in development.
What if research results after amniopunktsii unfavorable?
decision to conduct and performance of a particular cycle of prenatal examinations, including amniocentesis, should be carefully considered and weighed doctor both spouses.Our legislation is considered acceptable procedures for conducting abortion for up to twenty-two weeks, inclusive, in the case of confirmation of the existence of serious birth defects in fetal development by means of laboratory research and testing.
Early detection (using amniocentesis ) congenital, but is not critical to the life and health of the child, the defect will give both doctors and parents to prepare for the upcoming birth correctly.In such situations, the mother will be sent to a specialized clinic, where immediately after the birth of her child will fall under the medical supervision of experienced pediatricians.In some Western countries, even the attempts of surgical treatment of certain birth defects (such as kidney), even when the fetus is in the womb of his mother.Today, however, it is only a few cases.
