Fetometry of the fetus in weeks. The size of fetus by week

For any expectant mother should make sure her baby is growing correctly, without deviations and violations. So after the first ultrasound examination of the pregnant woman learns about the concept of fetometry of the fetus in weeks. This type of examination can find out the sizes of body parts of the fetus, to ensure that delivered by doctors of pregnancy and see possible deviations in the dynamics of child development.

The Main task of fetometry fruit

1. The doctors and the expectant mother after that the research method can ensure the proper level of development of the fetus, for example, to specify the size of the fetus, 5 weeks of which.

2. After 20 weeks it is possible to specify the sex of the baby.

3. Thanks to the first ultrasound you'll be able to contemplate the “first smile" your baby and fix it move.

Characteristics of the main indicators of the diagnosis

Fetometry of the fetus by weeks allows technicians to verify the correct development of the child. The first ultrasound examination has the following characteristics:

- CTE (kopchik-parietal size) characteristic for small periods of pregnancy, when the fetus has not yet reached the size of 20–60 mm.

- BDP (biparietal size) — this figure is connected with the second trimester of pregnancy and provides an opportunity to learn its term up to 10 days.

- DB (measurement of the length of the thigh) also makes it possible to estimate the duration of pregnancy, but the accuracy is slightly less — up to two weeks. This version of the study applied in the case where the previous measurement does not work to bring up to satisfactory standards.

- coolant (abdominal circumference) — a characteristic that is aimed at the study of the development of the fetus. It is now possible to visualize a short segment of the umbilical vein, the fetal stomach, gallbladder, and definitely venous duct. Therefore, such a thing as fetometry of the fetus in weeks, is very important in the evaluation process of the growth of the baby. It is important to observe a small recommendation — this measurement shall not be performed when the fetal weight greater than 4 kg.

- EXHAUST gas (volume of the chest) provides the opportunity for professionals to assess the duration of pregnancy 14-22 week.

Experts insist on the fact that for more reliable information ultrasound examination should be carried out comprehensively, in other words, at the same time. Thus, the concept of fetometry of the fetus in the weeks up to 36 is characterized by the studies for pregnant women as coolant, BDP and DB. After reaching this period, pay attention to coolant, EXHAUST and DB.

But here you should not be taken as law. Since it is necessary to look at the individual characteristics of fetal development and possible delays.

How to understand the reading of the conclusions of the study of Geometrie

Fetometry of the fetus by weeks were indeed very significant for doctors and parents of the future child. But not everyone will be able to understand the conclusion of experts in the absence of special higher medical education.

To determine the expected number of birth of your child, you should pay attention to the obstetric pregnancy. This date is easily calculated with the information about the first day of the last menstrual cycle. Thus it is necessary to take into account those indicators that were received after fotometrii. Although in this case there are different interpretations of the same indicator.

A Simple algorithm to read the conclusion of ultrasound

1. By knowing about the first day of the last menstrual period or day of conception it is possible to calculate the approximate birth date of the baby.

2. To verify the correctness of the calculation (the first paragraph) on the basis of performance of ultrasound examinations 1 or 2 trimester.

3. Information on the percentage of characteristics for DG, BPR, J.

4. The study of the probable delay in intrauterine development of the fetus.

Table of fetometry fruit

Of great importance Today for pregnant women is fetometry of the fetus. The table that the ultrasound examination indicates the main indicators of the normal development of the baby and there is any doctor that deals with obstetrics and gynecology. Therefore, expectant mothers will be able to control the process of “maturation” his child still in the womb. But it should correctly identify the exact period of pregnancy. And this is only possible after analysis of the testimony, tables of fotometrii.

In order to know the provisional date of the birth of your long awaited child, you need to calculate the available data according to the formula Negele. So, to the date of the last menstrual period is necessary to add a week, then take three months.

But in order to verify the accuracy of such calculations, it is necessary to take into account the results of ultrasonic examination. Although even in this case the possible error. Since diagnostic medical equipment may be inaccurate. And fetometry of the fruit table which is the main point of reference in the processultrasound examination of the several relative. She, too, has its variations.

We should not worry so much. Because the differences are insignificant and greatly affect the overall result will not.

Fetometry fetus by week, the table has indicators of child development, can be very useful not only for the mother but also for doctors.

Although in this case it is understood that all specifications are average value. This is all due to the fact that all children have different weight, height and other parameters. And so for greater accuracy it is necessary to pay attention only to the average rate.

You should Never panic if some parameters differ somewhat from the testimony table. Because fetometry fetus by week, the table which has only the General rules, at most a relative and is accepted only as a basic starting point. Although for peace of mind, you can still contact the experts for a deeper and more correct and proper execution.

If your excitement was confirmed and pathology has developed, it is necessary to immediately undertake all the necessary manipulations for the information of possible violations and health risks to a minimum.

Today, patologia lets you know not only the size of fetus by week, but at an early stage to fix the developmental delay of the child in the womb. Naturally, in order to make an educated conclusion, it is necessary to consider simultaneously a lot of factors, for example, the testimony of ultrasound, General health of pregnant women and physiological factors. But overall it's really. Indeed, in the analysis process experienced specialist will be able to correctly compare the obtained data of ultrasonic research and standards table of patologii. In that case, if they are very different, the pathology is almost always confirmed.

Normal size for the fetus in the womb

To date, the size of the fetus by weeks can be found through ultrasound of a pregnant woman. But in order that this information was useful and necessary, is something of a start. That is why special attention should be paid to designed your gynecologist pregnancy.

The normal size of the fruit does not have to be in the same line. All this is because the baby is growing in leaps and bounds. Therefore, there may be little variation.

For example, all indicators are ultrasound to normal, but the length of the femur and tibia bones do not coming to normal value. Do not immediately panic and think that it necessarily develops the disease. Because all people are different, maybe just your child's legs aren't that long, as evidenced by the standard. Although everything is actually okay and your baby is completely healthy.

It is important that the table size of the fetus will allow you to pay attention to the following: the danger in most cases is justified when, after another study of fotometrii certain values differs by more than two lines. In other words, when the visible pattern in the gap from the norm.

The Need of photometrie

Only procedure fotometrii, thanks to its ultrasonic component, will allow in early pregnancy to diagnose fetal developmental delay of the fruit. So, time to react and reduce the risk to a minimum. Malnutrition manifests itself in the moment when the parameters of the fetus behind the norm for more than 14 days.

Today it is possible to conduct ambulatory treatment of such a diagnosis and prevent deterioration in health and well-being of both mother and fetus. One of the methods of treatment is the rehabilitation of foci of infection, if the child is infected in utero. If necessary, you can adjust placental insufficiency or to engage in the formation of the diet of the baby before birth.

Because the new methods and ways of medical treatment to help the mother and baby during any complications.

Who can give a diagnosis of delay in the fetal development

To evaluate correctly the pregnancy, the size of the fetus in particular, should refer to the obstetrician-gynecologist or a specialist genetics. Because only they are authorized to call the diagnosis of intrauterine fetal growth retardation or malnutrition.

Moreover, the diagnosis is made only after evaluation of the genetic predisposition of the mother. And in the case of confirmation, it will be possible to find out the reasons of such consequences. Often the main “merit” of the appearance of pathologies are:

abnormalities in the chromosomes.

- the presence of harmful habits in the parents, especially the mother;

- age of the future parents;

infection in toddler that got in utero.

So fetometry of the fruit table which is characterized by only average values, several relative. Because it is considered the benchmark for determining compliance with the duration of pregnancy, calculated gynecologist, and the data obtained. As well as a certain control point symmetry or,on the contrary, of the asymmetrical development of the fetus in the womb.

First fetometry fruit

The First fetometry of the fetus is performed at gestational age of 10-14 weeks. Thanks to this ultrasound you can verify the correctness of the conclusion obstetrician-gynecologist date of birth of the baby, and also to exclude the possibility of abnormalities in the chromosomes and other abnormalities in fetal development. Particular attention specialists pay to kopchik-parietal size (CTE) of the fetus, abdominal circumference (RC) and the thickness of the nuchal translucency (NT).

Second fetometry fruit

Follow-up ultrasound examination of the typical 22 weeks of pregnancy. It is possible not only to clarify the process of development of their child, lack of pathologies, and other deviations from the norm, but also learn the sex of a baby.

Now it is necessary to carefully pay attention to the following characteristics of fotometrii: biparietal size (BDP) and head circumference (HC), abdominal circumference and femur length (DB). In this case, it is also important to consider progress in the development of the fetus in General and its parameters. After all, the kid is growing leaps and bounds, and so previous figures have return to normal. After all, the rules of Geometrie of the fetus we must also look very carefully, in further analyzing the overall picture of child development.

Third fetometry fruit

In most cases last for the expectant mother is considered to be the third fetometry of the fetus. 33 weeks pregnant - this is the last time of performing an ultrasound examination. It is now possible to see the perfectly formed baby, assess its condition and to judge the further way of childbirth. For example, measure the head circumference and abdomen, is an assessment of the symmetrical development of the paired limbs, as well as the forecast of the weight of the baby at birth.

In this case, if necessary, to conduct such a study, as fetometry of the fetus. 32 weeks is considered sufficient time for this kind of research pregnant women. If pathologies and striking deviations from the norm are not revealed, in the future, ultrasound is not necessary.

Conclusion

In the process of analyzing information after an ultrasound examination should definitely understand that the baby in the womb does not develop evenly. Since the development itself is characterized by discontinuity, in certain periods it is possible to track the deviation from the normative readings.

Moreover, special attention should be paid to the genetics of the parents and their physique. So, for example, a pregnant woman who weighs little and has a low height, will often be the owner of the fruit, which will also deviate from the norm according to the table fotometrii down. While big the expectant mother can have a child, which also significantly exceeds the standards on weight and General settings. Not to worry, because it is the individual characteristics of the child and his mother. And it has no effect. Because all people are different.

The verdict on the results of an ultrasound examination of fotometrii authorized only obstetrician-gynecologist or a specialist medical centre of genetics. Therefore, the expectant mother must follow all recommendations and instructions of doctors, including the appropriate conduct of a pregnant woman lifestyle.

It is only the absence of bad habits (or complete elimination), proper diet and adherence to the appropriate regime of the day will allow the light to appear healthy and active child to the delight of parents. Therefore, it is necessary to consider whether the life and health of the baby your weaknesses? Maybe a woman should ignore all the risks aside and change your life for the better. And the child - a reason to do it sooner, at least for him.
