Ultrasound in pregnancy: percentile is important
Pregnancy for a woman is a special condition, now it is important to understand that the future mother is responsible not only for her life, but also for the life of a small creature that is inside her. Only she can take care of the baby like no other. This does not remove the responsibility from the father, but nevertheless the mother remains just 24 hours a day with the future newborn baby. In order to have a full idea of how the baby is developing and everything is in order, it is necessary to register with a women's consultation. It is there that a pregnant woman will receive recommendations on lifestyle, habits, behavior and so on. Before that, the pregnant woman did not know that percentile is an important indicator, which is determined after the first ultrasound.
Surveys are important events
No mother initially taught her how she should behave, because pregnancy often occurs suddenly, even if this event was planned. Therefore, it is important to strictly follow the recommendations of the obstetrician-gynecologist and take all the tests on time, undergo examinations. All these activities are not invented so that the pregnant woman is not bored. These important examinations help in time to identify pathologies that will preserve pregnancy, and to monitor whether the baby is developing normally.
Ultrasound during pregnancy
One of the most important and mandatory examinations is ultrasound diagnosis. According to the requirements of the Ministry of Health, every pregnant woman should make 3 ultrasound examinations for the entire period of an interesting situation. The first is carried out in early terms - 12-14 weeks, the second - 20-24 weeks, the third - 30-32 weeks.
If the gynecologist has some doubts, additional ultrasound may be performed as needed. It is worth noting that the harmfulness of ultrasound for a child is a scientifically unconfirmed fact. These myths are spread by those who are simply not interested in excluding the development of pathological phenomena.
Important Ultrasound Information
During the course of ultrasound in the early stages and in the third trimester, various factors are determined that indicate how well the fetus is developing. Percentile is an indicator by means of which it is possible to confirm the fact of absence of genetic pathologies or their presence. If we talk about the first ultrasound examination, it is worth noting that this screening examination, which determines the following points:
- at this time, ultrasound is performed in order to confirm a normal pregnancy and exclude ectopic;
- real sizes of the fetus are determined;
- a more accurate gestational age is determined;
- examines and analyzes the state of the child’s internal organs and the mother’s genitals;
- collar space is measured, percentiles of children's weight are checked.
What is the collar space?
Collar space is the distance between the child's backbone and the inner extreme layer of his skin. This space is filled with liquid, it needs to be measured in order to determine how correctly the baby develops with respect to its physique, that is, whether its growth and weight are normal. You can determine this using special tables. When ultrasound is measured distance, then the percentile is checked - this is the value that is determined by the distance from the spine to the extreme layer of the baby's skin. If this indicator is in the range of normal sizes, then everything is fine, if the detected indicator is beyond the limits of normal values, then it is necessary to visit genetics. A referral is sent to a specialist who will prescribe additional methods of examination in order to determine the cause of such an indicator.
Percented - this is ...
Percentile during pregnancy is determined by special tables, no special knowledge in the field of obstetrics or mathematics is required. When studying the collar space, the neck fold of the fetus is evaluated. The increased size may indicate that there is a chromosomal disorder, some pathology, in particular, such may be Down's syndrome. In order to exclude or determine pathological changes, a number of other studies are being carried out, such as blood tests for alfa-fetoprotein, chorionic gonadotropin, and other invasive methods.
What does "percentile weight and height of a child" mean? This question can be answered only after you have the results of ultrasound in your hands. So, you have the distance from the spine of the fetus to his skin, take the table, you look for her indicator in millimeters. The table defines the percentile - this is the indicator that you are interested in. If it is less than 3% or more than 97%, then you can not avoid visiting the doctor.
The percentage of height and weight of the child is also determined after his birth. There is a table on which, according to the age of the child, it is possible to determine how many percentiles correspond to its height or weight. These are the simplest methods for analyzing a child's normal development.
