Dopplerography of the fetus. Norms of dopplerography of the fetus

The woman is the creator of humanity. And let the men do not take offense for the second plan, but it is within the woman that a new man grows and develops. For 40-42 weeks inside it there is a mass of complex and interesting processes that are interrelated. From one single small cell the baby is formed - and this is the most beautiful miracle on earth!

Proper balanced nutrition, special physical exercise for pregnant women, taking good vitamins, support and love of loved ones and daily walks in the fresh air - this is the basis of the health of an unborn baby.

Waiting for the baby is, perhaps, the happiest time in the life of every woman. And at the same time, every future mother is worried: is everything alright with the baby and is the long-awaited pregnancy normal?

To carefully monitor the entire process of pregnancy, a gynecologist usually prescribes many different tests, each of which is carried out on a certain week of pregnancy.

The very first analysis, which confirms that the baby is at the heart of a future mother, is an analysis for hCG (human chorionic gonadotropin, manifested only in pregnant women).
When the future mother will register, the gynecologist will give directions for such tests:

• Blood test for HIV AIDS;
• Analysis of the RV shelter (Wasserman reaction, in other words - syphilis analysis);
• general blood analysis;
• blood chemistry.

In addition, the laboratory will take an analysis of the presence of sugar in the blood, and also need to pass a general analysis of urine.

If the future mother has a negative Rh factor of blood, and the father of the child has a positive, then throughout the pregnancy the doctor will prescribe blood tests to study the presence of antibodies against the erythrocytes of the baby's future.

And, of course, no pregnancy takes place without such important studies as ultrasound and dopplerography of the fetus. All together allows you to monitor the condition of the pregnant and the baby, and quickly respond if something suddenly goes wrong.

Research Innovation

Dopplerography of the fetus is a relatively new method of examination, thanks to which it is possible to examine the blood flow in all organs of the still unborn little man, see whether his heart, kidneys and liver are developing correctly, and to assess whether the vessels in the umbilical cord, placenta and uterus of the future mother function correctly. This method is based on the Doppler effect and for the given time period is the most effective for accurate monitoring and providing the most accurate information about the state of crumbs.

Discovery of Doppler

The Doppler effect was discovered in 1842 by Austrian physicist Christian Doppler. He found that ultrasound changes frequency values when reflected from an object that moves. The ultrasonic scanner fixes the reflected ultrasonic wave, calculates the difference between the send and send back wave indices and displays the results in the form of a complex graphic picture.

For the first time in medicine, Doppler scanning was performed in 1955 by scientists from Japan, who in this way examined the operation of the valves of the heart and vessels. In gynecology and obstetrics, ultrasound dopplerography of the fetus was performed in 1964. Subsequently, the apparatus for ultrasound dopplerography was improved, and the norms of indices of the state of intrauterine development of the fetus were also studied and approved.

Everything's under control

Dopplerography of the fetus is scheduled for all, without exception, future mothers at the 32nd week of pregnancy, so do not get upset early and think that something is wrong with the baby. This is a standard procedure, thanks to which the doctor examines the condition of crumbs and the "mother-cord-baby-baby" system, and if there are any alarming moments - will take timely measures to eliminate them.

Early dopplerography in pregnancy is prescribed in the case of a complicated or multiple pregnancy at 22-24 weeks or simply for additional control of the placenta, umbilical cord and baby.

Risk group

In addition to standard routine studies, there are additional indications for conducting an unscheduled ultrasound of the fetus with dopplerography:

• Eclampsia and pre-eclampsia of a pregnant woman;
• Increased pressure, vegetative-vascular dystonia of the future mother;
• Problems with kidneys during pregnancy;
• Smoking pregnant;
• Rhesus-fetus and mother conflict;
• Pathology in previous pregnancies;
• Gestosis, toxicosis;
• Congenital or hereditary diseases.

Eclampsia is a severe toxicosis that manifests itself in late pregnancy, accompanied by convulsive convulsions and CNS damage. The probability of a coma is great , therefore eclampsia is very dangerous! It is preceded by preeclampsia, and if it is determined in time and the appropriate treatment is prescribed, the condition is normalized.

Forewarned is forearmed

The most important reason why dopplerography in obstetrics is an obligatory study is the threat of intrauterine fetal hypoxia.
The umbilical cord that connects the future mother with her baby has one vein and two arteries. On the arteries from the mother's body, the baby receives all the substances necessary for its development, including oxygen. The decay products are output via the umbilical vein. It is very important that everything works correctly. If there are any abnormalities in the umbilical cord, for example, narrowed blood vessels, and along with it nutrients, act slowly and in insufficient quantities. In utero hypoxia of the fetus develops, as a result of which the baby suffers from lack of oxygen and nutrition, and its organs can not develop normally.

At an initial stage of a hypoxia it is possible to notice, that the kid pushes very actively, if measures are not accepted - sufferings of crumbs proceed, frequency of perturbations considerably umyshshaetsja.

The sooner hypoxia is detected, the sooner the doctor will prescribe the necessary treatment, and the baby will be born healthy.

How is the examination performed

Dopplerography of the fetus is exactly the same as the most common ultrasound scan. As a rule, most modern ultrasound devices are equipped with a doppler. This is absolutely not painful and not terrible: the doctor will apply the gel-conductor to the pregnant woman's stomach and start gently driving the ultrasound mouse over it. The result of the research will be reflected first on the monitor of the device, and after that the protocol of dopplerography of the fetus will be printed on the printer.

Norms of indicators

The results of any study are usually compared with conventional indicators and the dopplerography of the fetus is no exception. Understand whether everything is normal - without a doctor is impossible, since the protocol of dopplerography of the fetus includes a huge number of digital indicators in which a person without special medical education can not figure it out. The main indicators of the study are IR (resistance index), PI (pulsation index) and SDO (systolic-diastolic ratio).

Not to harm

Doppler ultrasound of the fetus does not pose any danger to the baby and the future mummy. On the contrary, it is the best "assistant" who controls the course of pregnancy and helps to react quickly in case of any abnormalities.
