Today, an ultrasound examination is prescribed to identify and exclude early development of early development of early development. Throughout the pregnancy, women pass 3 ultrasound, one of the important indicators of which is the biparietal size of the fetal head or fruit BPR. According to the definition of modern BPR medicine, this is an indicator characterizing the distance from one of the most remote point of the wall of the parietal bone of the skull to another on the opposite bone. The size of the BPR indicates the size of the fetal head and the level of development of the nervous system of the poor child. In addition to these indicators, BPR also gives the doctor information about the possibility of passing the fetus through the birth canal without any obstacles and threats, both for the child and for the mother. According to this indicator, the doctor makes a decision on natural delivery, or on the appointment of a planned cesarean section. The combination of the BPR indicator with an indicator of lobno-consuming size makes it possible to characterize the degree of development of the fetus and determine the period of pregnancy by the head index. It is the definition of the exact gestational age that allows you to control the level of development of the poor baby and the removal of pregnancy. The BPR indicator can be determined for almost any week of pregnancy, but modern gynecology recommends an ultrasound for 12, 20 and 30 weeks of pregnancy. This indicator has its own peculiarity, with the development of the fetus, the change in the BPR slows down, that is, the growth of the fetal head slows down, if at the beginning of pregnancy the BPR adds about 4 mm per week, then at the end of the period only 1.3 mm of 1.3 mm. Determining such an indicator as BPR is a high -quality, fast and, importantly, safe and reliable method of studying the level of intrauterine development of the fetus.
