Today, each of us understands the importance ofpreservation and promotion of health. Young women became more attentive to themselves and their children. The desire of the future mother to give all the best to her child at the present time also implies taking care of his health during the fetal life of the fetus.

This trend led to the need forpay more attention to young mothers and the state in the form of providing them with all kinds of medical assistance. Improving the methods of diagnosis, the emergence of new methods of research - all this formed the basis of quality medical care. Ultimately, after all, prevention and diagnosis of diseases are those initial links in the chain that predetermine both the possibility of the development of the disease, so its severity and duration of treatment.

Today, there are many different ways andmethods for monitoring the course of pregnancy. Among them, the indicators of ultrasound of the fetus (ultrasound diagnosis) are often used. It is caused, first of all, by its safety for a growing organism and sensitive to all examinations of the body of a young mother. In carrying out this study, the most significant indicator is the fetal BPR (the biparietal size of its head).

The definition of biparietal size isone of the most commonly used methods for assessing the development status of the fetus in modern medical practice (used directly in obstetrics and gynecology).

What is BDP fetus? As mentioned above, this indicator is determined by visualizing ultrasound waves at the level of the 3rd ventricle of the brain. Biparietal size characterizes the actual distance between the most distant points of the opposite walls of the parietal bones of the skull. BDP of the fetus refers directly to the size of the fetal head and, as a consequence, the level of development of its nervous system.

In addition, this indicator determinesthe possibility of passing a child through the birth canal without causing harm to the health of both the baby itself and the mother. The received data allow to choose the correct method of delivery. In the event that the size of the fetal head does not correlate with the dimensions of the birth canal, regardless of the cause (narrowed birth canals or a large fetal head), operations for delivery (caesarean section) are performed.

Speaking about the size of a baby's head, it is worth notingsuch an indicator as frontal-occipital size, which when combined with BPR allows to characterize the level of development of the child, as well as the duration of pregnancy for the head index. And, ultimately, it is the knowledge of the term of pregnancy that allows you to know about the condition of the fetus. The latter allows you to correctly assess such issues as miscarriage or pregnancy overdose.

To judge the data of BDP fetus, the norm of whichdeveloped for every week of pregnancy, you can at any time of pregnancy, but most often the ultrasound of the fetus is carried out in the second and third trimesters of pregnancy.

The definition of biparietal size allows us to judge the development of the brain (by the size of the cranium) and the nervous system.

A feature of this indicator isslowing its changes with time in developing the fetus. So, BDP fetus, or rather the rate of its growth on the fourteenth week of pregnancy is about 4 millimeters per week. By the end of pregnancy, the rate of increase of this indicator falls significantly and is only 1.3 mm.

Thus, to determine the development of the fetal organism, there is a qualitative, fast, and most importantly, safe technique - the determination of biparietal size.
