Fetometry of the fetus for weeks. Fetal size for weeks
For any future mother, you need to be sure that her baby develops correctly, without different deviations and irregularities. Therefore, after the first ultrasound examination, a pregnant woman learns about such a concept as fetometry of the fetus for weeks. Due to this type of ultrasound examination it is possible to find out the dimensions of the fetal body parts, to make sure of the correctness of the term of pregnancy set by the doctors and to see possible deviations in the dynamics of the child's development.
The main task of fetometry of the fetus
1. Doctors and a prospective mother after this method of research will be able to ascertain the proper level of development of the fetus, for example, to specify the size of the fetus, 5 weeks old.
2. After 20 weeks you can specify the sex of the future baby.
3. Thanks to the first ultrasound, you can contemplate the "first smile" of your baby and fix his stirring.
Characteristics of the main indicators of diagnosis
- KTP (coccyx-parietal size) is characteristic for small gestation periods, when the fetus has not yet reached a size of 20-60 mm.
- BDP (biparietal size) - this indicator is associated with the second trimester of pregnancy and provides an opportunity to find out its term with an accuracy of 10 days.
- DB (measuring the length of the thigh) also makes it possible to estimate the gestational age, but the accuracy is somewhat less - up to two weeks. This variant of the study is applied in the case when the previous measurement does not work out to a satisfactory rate.
- OJ (abdominal circumference) is a characteristic that is directed towards the development of the fetus. After all, it is now possible to visualize a short segment of the umbilical vein, the fetal stomach, the gallbladder and necessarily the venous duct. Therefore, such a concept as fetometry of the fetus for weeks, is very important in the process of assessing the growth of the baby. It is important to observe a small recommendation - this measurement can not be carried out when the fetus is over 4 kg in weight.
- OG (chest volume) provides an opportunity for specialists to estimate the duration of pregnancy at 14-22 weeks.
Experts insist that ultrasound studies should be carried out in a complex way, in other words, simultaneously to obtain more reliable information. So, the concept of fetometry of the fetus for weeks at a term of up to 36 is characterized by such studies for pregnant women as OZH, BPR and DB. After reaching this deadline, they pay attention to the coolant, exhaust gas, and combustion air.
But here you should not take everything as a law. Because it is necessary to look at the individual characteristics of fetal development and possible delays.
How to independently understand the perusal of the conclusion of studies of fetometry
In order to know the estimated number of births of your child, it is worth paying attention to obstetric pregnancy. This date is easily calculated due to information about the first day of the last menstrual cycle. At the same time, it is necessary to take into account those indices that were obtained after carrying out the fetometry. Although in this case, different interpretations of the same indicator are possible.
The simplest algorithm for reading the conclusion of ultrasound
2. Make sure the correctness of the calculation (from the first paragraph) can be based on the indicators of ultrasound studies of 1 or 2 trimester.
3. Information on the percentage of characteristics for DG, BPR, JG.
4. Study of the probable delay in fetal development of the fetus.
Fetal Fetometry Chart
Today fetometry of fetus is of great importance for pregnant women. The table of such an ultrasound test indicates the main indicators of normal development of the baby and is available to any doctor who deals with obstetrics and gynecology. Therefore, future mothers will be able to calmly control the process of "growing up" of their child in the womb. But for this it is worthwhile to correctly identify the exact period of pregnancy. And this is possible only after analyzing the indications of the table of fetometry.
In order to know the preliminary date of birth of your long-awaited child, it is necessary to calculate the available data by the formula of Negele. So, by the date of the last menstruation, you need to add a week, and then take three months.
Nevertheless, in order to ascertain the accuracy of such calculations, it is also necessary to take into account the results of the ultrasound examination. Although even in this case, errors are possible. Since the diagnostic equipment of medical institutions can be inaccurate. So the fetometry of the fetus, the table of which is considered the main reference point in the process of ultrasound examination, is somewhat relative. After all, it also has its own variations.
Fetometry of the fetus for weeks, the table of which has indicators of the development of the baby, can be very useful not only for the future mother, but also for doctors.
Although in this case it is worthwhile to understand that all characteristics are given in the mean value. This is all due to the fact that all children have different weight, height and other parameters. Therefore, for greater accuracy, it is worth paying attention only to average norms.
You should never panic if some parameters are slightly different from the table. Fetometry of the fetus for weeks, the table of which has only general norms, is mostly relative and is accepted only as the main reference point. Although to calm the soul, you can still turn to specialists for a deeper and more competent conclusion.
If your anxiety is confirmed and the pathology has already developed, then you must immediately take all the necessary manipulations to minimize possible violations and health risks to a minimum.
Today, fetology allows you to learn not only the size of the fetus for weeks, but also at an early stage to fix the delay in the development of the baby in the womb. Naturally, to make a competent conclusion, it is necessary to take into account a lot of factors simultaneously, for example, ultrasound, the general state of health of a pregnant woman and all physiological factors. But in general, this is real. After all, in the process of analysis, an experienced specialist will be able to competently compare the obtained ultrasound data and the norms from the table of fetology. In the event that they are strikingly different, the pathology is almost always confirmed.
Fetal size in the womb
To date, the size of the fetus for weeks can be recognized through an ultrasound study of a pregnant woman. But for this information to be useful and necessary, it is worth starting from something. That is why special attention should be paid to the gestational period calculated by your gynecologist.
| Obstetric pregnancy week | Fetal weight, g | KTP, cm | OG (DGC), mm | DB, mm | BPR, mm |
| 14 | 52 | 12.3 | 26th | 16 | 28 |
| 22 | 506 | 27.8 | 53 | 40 | 53 |
| 33 | 2088 | 43.6 | 85 | 65 | 84 |
The size of the fetus need not be in the same line. All this is because the baby is developing spasmodically. Therefore, a small spread is allowed.
It is important that the table of the size of the fetus will allow you to pay attention to the following: the danger in most cases is justified when after the next study of fetometry certain values differ by more than two lines. In other words, when there is a regularity in the backlog from the norm.
The need for fetometry
Only the procedure of fetometry, due to its ultrasonic component, will allow early detection of an intrauterine delay in fetal development. So, in time to react and reduce the risk to a minimum. Hypotrophy manifests itself at a time when the parameters of the fetus lag behind the standard for more than 14 days.
To date, it is possible to conduct outpatient treatment of such a diagnosis and prevent deterioration in the well-being and health of both the mother and the fetus. One of the methods of treatment is the sanation of foci of infection if the child is intrauterously infected. If necessary, you can adjust the placental insufficiency, or engage in the formation of a baby's diet before he is born.
After all, new methods and methods of medical treatment will help mother and child in the process of any complications.
Who can diagnose a delay in fetal development
To evaluate correctly pregnancy, the size of the fetus, including, it is worth talking to an obstetrician-gynecologist or to a specialist in genetics. After all, only they are authorized to call a diagnosis of intrauterine retardation of fetal development, or hypotrophy.
Moreover, the diagnosis will be made only after the evaluation of the genetic predisposition of the future mother. And if it is confirmed, it will be possible to find out the reasons for this effect. Often the main "merits" of the appearance of pathologies are:
- Anomalies in chromosomes;
- the presence of bad habits in parents, especially the mother;
- the age of future parents;
- an infection in the baby that got in utero.
Therefore fetometry of the fetus, the table of which is characterized only by averaged indicators, is somewhat relative. After all, it is considered a benchmark for determining the correspondence of the gestational age, which the gynecologist calculated, and the data obtained. And also a certain control moment in symmetry or, conversely, asymmetric development of the fetus in the womb.
The first fetometry of the fetus
The first fetometry of the fetus is carried out at the term of pregnancy in 10-14 weeks. Thanks to this ultrasound study, you can make sure the birth date of the baby is correct by the obstetrician-gynecologist, and also eliminate the possibility of anomalies in chromosomes and other pathologies in the development of the fetus. Special attention is paid to the coccyx-parietal size of the fetus, the circumference of the abdomen (OC), and the thickness of the collar space (TPR).
Second fetometry of the fetus
Subsequent ultrasound is characteristic for the 22nd week of pregnancy. In this case, you can not only clarify the development of your child, the absence of pathologies and other abnormalities, but also to know the sex of the future baby.
Now carefully consider the following characteristics of phytometry: biparietal size (BPR) and head circumference (OG), abdominal circumference and thigh length (DB). In this case, it is also important to consider the progress in fetal development in general and its parameters. After all, the baby is growing in leaps and bounds, and therefore the previous indicators need to be normalized. After all, the norms of fetometry of the fetus should also be looked at very carefully, further analyzing the overall picture of the child's development.
Third fetometry of fetus
At the same time, if this is necessary, earlier research such as fetometry of the fetus can be carried out. 32 weeks are considered a sufficient time for this kind of research of a woman in the situation. If pathologies and striking abnormalities are not detected, then there is no need in ultrasound investigation.
Conclusion
In the process of analyzing the information obtained after ultrasound examination, it is worthwhile to understand that the baby in the womb of the mother does not develop evenly. Since the development itself is characterized by spasmodicity, from this in certain periods it is possible to track deviations from normative indications.
Moreover, special attention should be paid to the genetics of parents and their physique. So, for example, a pregnant woman, who weighs a little and has a low growth, will often be the owner of the fetus, which will also deviate from the norm according to the table of fetometry in the smaller direction. While a large future mother may have a child who also significantly exceeds the standards for weight and general parameters. Do not worry, this is an individual characteristic of the baby and his mother. And it does not affect anything. After all, all people are different.
To issue a verdict on the results of an ultrasonic examination of fetometry is authorized only by an obstetrician-gynecologist or a specialist in the medical center of genetics. Therefore, the future mother must necessarily follow all the recommendations and instructions of doctors, including lead a lifestyle appropriate for a pregnant woman.
After all, only the absence of bad habits (or complete rejection of them), proper nutrition and observance of the appropriate regime of the day will allow a healthy and active child to appear for the joy of parents. Therefore, you need to immediately think about whether the life and health of the baby is your weakness? Perhaps, a woman should throw all risks aside and change her life for the better. A child - an excuse to do it earlier, at least for his sake.
