Today, each of us understands the importance of maintaining and promoting health. Young women began to be 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 means taking care of his health during the fetal existence.
It is this trend that has led to the need to pay more attention to young mothers and from the state in the form of providing them with all kinds of medical care. Improving diagnostic methods, the emergence of new research methods - all this formed the basis for quality medical care. In the final analysis, it is precisely the prevention and diagnosis of diseases that are the initial links in the chain that determine both the possibility of developing a disease, its severity and duration of treatment.
Today, there are many different ways and methods to monitor the progress of pregnancy. Among them are often used indicators of ultrasound of the fetus (ultrasound diagnosis). This is caused, first of all, by its safety for a growing organism and a young mother sensitive to all examinations of an organism . When conducting this study, the most significant indicator is the fetal BPR (biparietal size of its head).
The determination of biparietal size is one of the most commonly used methods for assessing the state of fetal development in modern medical practice (it is used directly in obstetrics and gynecology).
What is bipolar fetus? As mentioned above, this indicator is determined by visualizing ultrasonic 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. Fetal bipolar disorder indicates directly the size of the fetal head and, as a result, the level of development of its nervous system.
In addition, this indicator determines the possibility of the passage of the child through the birth canal without causing harm to the health of both the infant and the mother. The data obtained allow you to correctly choose the method of delivery. If the size of the fetal head does not correlate with the size of the birth canal, regardless of the cause (narrowed birth canal or large fetal head), delivery is performed (cesarean section).
Speaking about the size of the baby’s head, it is worth noting such an indicator as the fronto-occipital size, which, when combined with BDP, allows you to characterize the level of development of the child, as well as the duration of pregnancy by the head index. And, ultimately, it is knowledge of the gestational age that allows you to find out about the condition of the fetus. The latter allows you to correctly evaluate such moments as preterm or prolongation of pregnancy.
It is possible to judge the fetal BPR data, the norm of which is developed for each week of pregnancy, at any stage of pregnancy, however, most often, fetal ultrasound is performed in the second and third trimesters of pregnancy.
The determination 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 is the slowdown of its changes over time with the development of the fetus. So, the BDP of the fetus, or rather, its growth rate at the fourteenth week of pregnancy is about 4 millimeters per week. By the end of pregnancy, the rate of increase of this indicator drops significantly and is only 1.3 mm.
Thus, to determine the development of the fetal organism, there is a high-quality, fast, and most importantly, safe method - determining the biparietal size.
