In addition to numerous tests, monthly visits to a gynecologist and other specialists, each expectant mother is offered to conduct 3-4 ultrasound examinations. Ultrasound is currently considered the most informative method of examining fetal health during pregnancy, and all assumptions about the insecurity of this method have not been proven. So, what and at what time can you "see"?Women are offered to undergo the first screening (planned) ultrasound examination on average at 11-14 weeks of waiting for a baby. By this time, the expectant mother should already be registered at the polyclinic, undergo an examination and pass the necessary tests. Those who have done an ultrasound of the abdominal cavity are well aware that this examination is absolutely harmless to the body. The first ultrasound diagnoses uterine or ectopic pregnancy, excludes chromosomal abnormalities and serious malformations of the fetus, which are sometimes incompatible with life, specifies the duration of pregnancy. In some cases, ultrasound is performed at an earlier date (for example, at 4 weeks) in order to confirm the presence of an interesting position or to determine the condition of the embryo if pregnancy occurred as a result of IVF.The second scheduled ultrasound is usually performed in the middle of the second trimester, at about 20-24 weeks. One of the main goals of ultrasound diagnostics at this time remains the identification of possible fetal abnormalities. The doctor can already assess the size of the child in more detail than in the first trimester, the activity of his organs and systems, it becomes possible to listen to the heart rate, study the condition of the placenta in detail. And at this time it is already possible to see some of the baby's facial features and determine his gender, even if not with 100 percent probability.The third screening ultrasound examination is prescribed between 32 and 34 weeks of pregnancy. At this time, the weight and size of the fetus, the condition of the placenta are determined, and the presence of those malformations that cannot be determined at an earlier date is also diagnosed. In some cases, an additional ultrasound may be performed at 36-37 weeks, immediately before childbirth or during pregnancy. Usually, additional diagnostics are assigned to expectant mothers with excess weight, and the main purpose of such a study is to clarify the position and presentation of the fetus, its weight.Despite the fact that the harm of ultrasound has not been proven, it is not necessary to carry out additional diagnostics if there are indications for this.
