When is it best to do the first ultrasound in pregnancy?

During pregnancy, the expectant mother rents a number of analyzes and passes inspection, allowing to evaluate the development of the fetus and the health of the woman. These certainly include ultrasound examination of the pelvic organs.

Thanks to transvaginal sonography in 3 weeks after conception, you can see the fertilized egg in the uterus, and a week later - and its inhabitants.

Many pregnant women mistakenly believe that if they are healthy and feel great, the ultrasound during pregnancy can not do. This view is not very true, because in medicine, including obstetrics, it is of great importance is the preventive approach rather than correcting an existing situation. In favor of the ultrasound study says the following:
• in almost ninety percent of the defects in fetal development occur in completely healthy parents, and to identify it quickly and safely is possible only with the help of ultrasound;
• exactly recognize the multiple pregnancy as possible only by means of ultrasound, other methods and techniques this can not cope;
• the timely passage of ultrasound to avoid interruption of pregnancy (abortion), since it allows to identify various pathologies during pregnancy;
• ultrasound allows you to set the most accurate gestational age, which is very important in determining fully whether the development of the fetus or not whether it date or vice versa.

It was established that even with repeated exceeding allowable intensity ultrasound in the diagnosis of harmful effects to mammalian embryos not.

But the negative consequences of the refusal of the ultrasound in the first trimester is very clear. Every year in Moscow, about 100 children are born with Down syndrome.

According to the results of each study protocol filled ultrasound diagnostics. This protocol is issued woman "in his hands", she sends him an obstetrician-gynecologist. Sometimes the record of such a protocol seems incomprehensible woman, she begins to worry: as if everything is OK, it may be something wrong? So do not be shy - anything that raises questions, doubts, it is necessary to learn from the experts. Recall also that it is better to make copies of any research results and store them at home.

Ultrasound is a mandatory component of the procedure of pregnancy. Use in obstetrics ultrasound has allowed to visualize not only the fetus, placenta, umbilical cord and amniotic fluid, but also the various organs of the fetus and their structural elements.

Modern ultrasound allows assessment of the fetoplacental system in the earliest stages of pregnancy, allows to objectively evaluate the development of the fetus throughout pregnancy, to diagnose in early stages, delay its growth and take appropriate measures.

The use of the Doppler effect to assess fetal development, have made possible the detection of fetal abnormalities in the early stages , which significantly reduced the number of births of children with disabilities.

In the process of prenatal care provided the 3 necessary ultrasound.

The first ultrasound is recommended to do in the period of 12-14 weeks. This stage includes evaluation of the anatomy of the fetus and the condition of the chorion. The measured nuchal translucency thickness for detection of the risk of congenital malformations and chromosomal pathology. Based on experience, recommended without special necessity not to do the ultrasound before then.

The second ultrasound held on the 22-24 week period. It is carried out to assess the anatomy of the fetus, placenta and amount of amniotic fluid for detection of the CDF and markers(absolute and relative) of chromosomal abnormalities. At this time you will be able to learn your baby's gender.

The third ultrasound done at 32-34 weeks term. During this period, the possibility of developmental delay, excluded some types of fetal abnormalities, which could not be detected at an earlier timing, is determined by the amount of amniotic fluid, which is important for diagnosis of some form of suffering of the fetus.
