What is Doppler?
Doppler ultrasound is used to evaluate the blood flow of a baby in various organs. However, this study diagnoses the general condition of the fetus. The procedure is important for assessing the functioning of the placenta and blood flow in the uterine arteries. Doppler ultrasound (Doppler ultrasound) is of great importance for pregnant women with coagulation disorders. If the condition of fetal development is assessed, then the Doppler ultrasound should be used in conjunction with cardiotocography and echography. According to the results of a doppler ultrasound, a doctor can correct a pre-planned pregnancy and even delivery schedule.
The high degree of informativeness and safety, as well as the use of ultrasound diagnostics with doppler in the early stages of gestation, makes this study indispensable in complex prenatal diagnosis.
Dopplerography is carried out together with a planned ultrasound and on the same equipment, because most ultrasound machines today have the function of a dopplerograph as an additional one.
At the beginning of the diagnosis, the doctor diagnoses the position of the vessel, which should be checked, for example, the blood flow in the vessels of the organs of the gastrointestinal tract. After that, it includes the function of dopplerography - and a picture appears on the screen showing the state of blood flow in the desired organ. Then the device analyzes the received data. The duration of such manipulation is several minutes.
When is dopplerography prescribed?
You should know that dopplerography is prescribed by the attending physician to all future mothers at the 32nd week of pregnancy. If there are complications in bearing a child, suspicion of fetoplacental insufficiency, then this study is prescribed earlier. It can be a period of 22-24 weeks of pregnancy. Usually, dopplerography is prescribed for multiple pregnancies, namely, with the bearing of twins with the common placenta, with the Rh contuse of the pregnant and the child, the delay in its intrauterine development, the presence of pathologies in the course of previous pregnancies and the poor results of cardiotocography.
If the baby is too small for the established period of pregnancy, then dopplerography will check the placenta and will assess the blood flow through the umbilical cord to the fetus. It has 2 arteries and 1 vein. Blood on the arteries comes to the fetus from the placenta and supplies the baby with the necessary nutrients, vitamins and oxygen. Through the vein of the cord from the fetus to the placenta, the products of disintegration that are unnecessary to the child are excreted. Only low resistance in the umbilical arteries will ensure a normal supply of blood and nutrients to the baby. With increased resistance in this supply, problems begin, and the child develops abnormally. If Doppler showed that the umbilical vessels are all normal, then the small size of the fetus is not terrible. Perhaps the reason for this is in a miniature mother, that is, a genetic predisposition.
When the resistance in the vessels is increased, doctors can decide to carry out preterm labor.
So, you do not need to be afraid of a new word and additional examination, if necessary. After all, it can only help to give birth to a healthy child or to calm a future mother.
