- Ultrasound during pregnancy - controls the development of the fetus
Ultrasonography (US) in pregnancy is an important diagnostic tool for monitoring the development of the fetus. With the help of ultrasound during pregnancy can get a fairly clear picture of the fetus, placenta, uterus and other pelvic organs. This procedure allows the doctor to get valuable information on pregnancy and child health.
When do ultrasound in pregnancy
Standard timetable ultrasound during pregnancy - three studies in each trimester. If there is some kind of pathology pregnancy is an individual schedule ultrasound. Dates of ultrasound during pregnancy in the antenatal clinic try to observe.
The first ultrasound may be performed already at 11-13 weeks after conception, to confirm the pregnancy and to establish more precisely its term. US in the early stages can also be carried out in cases of suspected miscarriage

or ectopic pregnancy. Pregnancy in this case is determined by the presence of the fetal heart, which appears in the second week of fetal development.
Late formulation of pregnant women registered in antenatal first ultrasound sometimes do in the middle of pregnancy. Women who were registered in time for 21-24 weeks a second pregnancy ultrasound pi. At this time, you can find out the sex of the child, to receive his first "picture" - a printout of the image obtained using sound waves, as well as to identify the majority of malformations.
The third ultrasound in pregnancy conducted on 32-34 week. It is a control and identify possible abnormalities before birth. Routine ultrasound during pregnancy allows almost complete control over the process of fetal development.
In addition to the planned research doctor can prescribe and unplanned. For example, under certain complaints women spend an abdominal ultrasound during pregnancy. This allows you to quickly identify diseases of the gastrointestinal tract, liver, pancreas,

and so on. Renal ultrasound during pregnancy can be identified and promptly treat various diseases of the urinary system. Pelvic ultrasound in pregnancy enables timely identification of ectopic pregnancy. Time spent in the US of an ectopic pregnancy can prevent serious complications. It is also important thyroid ultrasound

during pregnancy, as a violation of the thyroid gland during pregnancy can lead to the birth of a mentally disabled child.
Effect of Ultrasound pregnancy - how dangerous it is?
Clinical experience of recent decades shows that ultrasound is safe, it does not adversely affect either the woman or the fetus. Extensive and long-term studies conducted over the last 35 years, could not find any evidence of who ultrasound during pregnancy can be dangerous for the baby or the mother. During ultrasound organism is not exposed to ionizing radiation (such as during radiography). At the same time, experts do not recommend to spend US often required, stressing that, although the negative effects of this procedure has not been identified, ultrasound - is, after all, the kind of energy that can, in one way or another, affect the child. It is especially important to consider this during the first trimester, when the baby is most vulnerable to various external influences.
But the benefits of ultrasound is difficult to overestimate: through this study can almost know exactly how the intrauterine development of the child and, if necessary, to take urgent measures for prevention and treatment of complications of pregnancy. Ultrasound during pregnancy planning allows you to quickly identify and treat many diseases of women.
Types of ultrasound in pregnancy
In most cases, pregnancy transabdominal ultrasound is used, but sometimes the procedure is performed through the vagina (transvaginal ultrasound).
With transabdominal ultrasound at the abdomen of the patient applied the gel, which improves the conductivity of the sound waves. The doctor then leads to the stomach probe and a computer converts the echoes from sound waves into an image that is displayed on the screen. Bone and soft tissue in the image appear light and gray, while the dark area - is amniotic fluid. Preparation for ultrasound in pregnancy includes water load.
During the ultrasound the doctor records the size of the head and other parts of the child's body and takes pictures; Later, he will give them to a gynecologist, who is pregnant patient. The woman in this case can observe the image on the screen, but it is not necessary to ask questions directly to the doctor during the study - it should focus on the procedure to correctly interpret what he sees. Later he will be able to answer the questions. Conventional ultrasound procedure lasts 15 to 20 minutes. When using additional, more sophisticated equipment, it can take 30 to 90 minutes.
Transvaginal (vaginal) ultrasound during pregnancy passes as well as transabdominal, with the difference that a special probe inserted into the vagina and pre-water load is not required. Therefore, this study is sometimes called the "internal ultrasound during pregnancy." Vaginal study may cause some discomfort, but in some cases, such as early pregnancy, this procedure provides a more detailed image.
Doppler ultrasound and pregnancy (Doppler) - with the help of this study assessed the blood circulation in the blood vessels of the placenta, uterus and fetus. Dopplerographic survey results allow to draw conclusions about the state of the fetus and determine the future tactics of pregnancy.
