Since registered for the health of women and the fetus, obstecra-gynecologists are closely followed. Throughout the period of gestation, the pregnant woman undergoes scheduled surveys. Some problems found can be solved by therapeutic or surgical path, others require abortion. One of the mandatory diagnostic methods that allows you to find out the parameters of the development of the fetus, is fetometry. How do fetometry and what indicators are considered the norm?
What includes fetal fetterity? This is determining the size of the fetus - growth and weight. At ultrasound diagnostics, such indicators are considered key (their abbreviation in Russian and English and decoding):
fetometry is carried out using ultrasound. Pregnant woman passes Sonography according to plan in every trimester - for 11-14 (most often 12th) weeks, 18-21 weeks and on 32-33 weeks. As a rule, Sonography is carried out with the usual way through the abdominal cavity or transvaginally. No special preparation for the study is not required, only in the first trimester before the transabdominal examination of a woman needs to drink 1 l of water 1 hour before the office to visit the bladder is complete.
Only on fetometry It is impossible to draw conclusions about the correct development of the fetus. The parameters of the child will largely depend on its genetic and individual characteristics. If the mother and father are large, then the baby will be discovered in the development of peers. When the growth delay, it is necessary to prescribe a re-ultrasound after 2 weeks, often the baby has time to pull up by this time.
The first screening ultrasound examination is sent shortly after a woman's registration. The optimal date of ultrasound diagnostics is 11-12 weeks, but if the pregnant woman appealed to the female consultation later, it can be directed to Sonography immediately. Why are Screening surveys prescribe for these deadlines? One of the most significant indicators in the early stages of gestation is the thickness of the collar space of the embryo. Previously, this parameter is indistinguishable, and after the 14th week it is filled with lymph, distorting readings.
What is the embryo in comparison with fruit? Until the first month, he reminds of the size of poppy grains. By the end of the second month, it corresponds to a large grape 5 cm. In the period of the first fetometric study, it will be comparable with ripe figs at 7 cm.
Fetometry Fetal is one of the stages of ultrasound, which is usually assigned to a protocol-specific period of pregnancy or is carried out unscheduled under clinical indications to identify possible pathologies. This painless, non-invasive and safe study is carried out to evaluate several sizes of a developing fetus and allows you to detect possible pathologies. The resulting data on the future kid is decrypted using special tables displaying their indicators for each child to wear a child.
The measurement of the parameters of the fetus is performed during ultrasound scanning, the principle of which is based on the ability of ultrasound waves to reflect the tissues with different density. The doctor sets the sensor emitting the waves at certain points of the beginning and the end of the body parts of the future kid, and then the results are fixed, read and processed by a computer program. During the study, the body of the future mother and the fetus is not exposed to harmful factors for health, and the procedure can be carried out at any time.
Most often, these sizes are estimated at all fetometric studies. And after the 20th week, an exemplary weight of the fetus (VP) can be treated with their analysis. In addition, there are other parameters of the fetus in the study results table, reflecting its physical development:
Additional measurements are usually carried out to identify pathologies that have been diagnosed with other studies or when evaluating family history data on the possibility of inheritance of chromosomal anomalies.
Analyzing all data obtained during photometry and ultrasound scanning data, an obstetrician gynecologist can monitor the growth of the fetus, the state of the internal systems and the bodies for weeks. Deciphering the data obtained allows you to detect genetic diseases, anomalies and violations in the development of the future baby, planning the possibility of a normal passage of the fetus by generic paths and the method of a root separation. If necessary, the usual Uz-scanning complements the Dopplerometry, which allows to assess the nature of the blood current in the blood vessels of the fetus and the uterus, and at later cards - cardiography, which is performed to assess the heart rate of the future child, the tone of the uterus and determining the further way of conducting birth.
Child size for weeks pregnancy is averaged data for which the doctors track the development of the fetus in the tummy in the future mother. These figures affect the genetic predisposition, the physical and emotional state of the woman.
The growth of the baby in the tummy in mom, its changes in weight and length are important indicators of its development and health. By 7 - 8 week, the baby weighs about gram. But every day he grows and gains weight. Up to 15 weeks there is a rapid set of mass, after which it slows down. From the 2nd trimester, the weekly increase is about 80 grams and from 28 to 30 weeks the purchase goes a week to 300 grams.
Doctors in clinics and women's consultations are focused on ultrasound research data. At ultrasound examination, the accurate period of gestation is established and fixed the main indicators of the development of the baby in the tummy at the mother.
Accurate diagnosis involves the use of ultrasound research methods. Based on the results obtained, the specialist may establish how proportionally the baby develops, and whether the data obtained relative to the growth and development of established standards is compliant.
key parameters to determine the features of the development of the fetus are indicators of its growth and weight, but they begin to engage only in the second part of the first trimester. Until that time, the sizes of the embryo are so insignificant that their measurement is extremely difficult.
According to medical testimony, each pregnant woman is obliged to pass at least three ultrasound research procedures throughout the nine months. This number of procedures is considered minimal and can be increased by the decision of the specialists, if there is a need to receive additional information on the development of the fetus.
Periodic Conducting Ultrasound is necessary for the timely detection of serious pathologies and preventing the development of complications. As a rule, such studies are carried out not earlier than 10 and no later than 14 weeks, as well as in the second trimester in the period from 18 to 21 weeks.
The results of each ultrasound are recorded in protocols from which information can be obtained regarding the symmetry of the development of the fetus, the rate of its growth and compliance with the indicators established and used norms.
At the time of conception, two cells are connected - so small that they cannot be selected without the help of a microscope. Of them, the zygote is formed, which begins to share quickly. Embryo is formed, the dimensions of which are rapidly increasing every day. After 3 weeks after conception, an ultrasound can be defined a fruit egg in the ultrasound and fix the heartset of the fetus.
First of all, the size of the fetus depends on the periods of gestation. There are certain standards for which doctors are focused. Most fruits in the first half of pregnancy have comparable dimensions. Differences are becoming more significant only in the second half of the gestational period. The closer to childbirth, the greater the difference.
The size of the fruit differ, and this is quite normal. However, sometimes they go beyond the norm. This can happen with many different diseases or complications of the gestational period. For example, with fetoplasate insufficiency, the fruit will grow slower, and in the case of diabetes mellitus, it can be very large.
A few more decades ago, no one can find out the size of the fetus. The baby could measure only after delivery. Of the visualization methods, there was only X-ray. But it gives a radial load, so it is not used in obstetrics.
But since the ultrasound appeared, you can measure the fruit at any time in all of its sizes. This is done with each procedure. During the ultrasound diagnostics, the doctor assesses not only the body length at the moment, but also growth rates. It is estimated to match the size of the fetus gestation.
In the first 3 months of intrauterine development, the fruit is very small. Up to 12 weeks, it is turned on with an embryo inclusive, since the final bodies and systems have not yet been formed. At the time of the first screening ultrasound, the fetal length is usually about 7 centimeters.
When a new life is emerging in you and rapidly develops, it is very interesting to know which baby is now size, how much he weighs and what is his length. For each new week, the child is rapidly increasing, especially for the first trimester, when for every seven days the baby grows almost twice. In this article, you will delete the standard sizes of the child for weeks of pregnancy.
up to 19 weeks The table below shows the length of the baby from the top of the tail, and starting from 20 weeks the child's length from the top of the heels. To be clear, the size is indicated in comparison with grains, fruits and vegetables. Thanks to this, you can clearly imagine what size is your baby at the moment. The dimensions are indicated on the third and fourth week for the reason that the gestational period of pregnancy is counted from the first day of the last menstruation, and the conception itself occurs in the middle of the cycle during ovulation.
That's just in just 40 weeks, the kid grows out of the weightless "poppy grain" in the fruit, the size of the real watermelon. Very fragile, valuable and cute heart of watermelon. During these forty weeks, the weight of the kid increases at 3 billion times, and this is a real miracle!
The following tables provide data on biometric fetal indicators that are measured at each. They are represented in 10, 50 and 95 percentiles. Most often are oriented by 50 percentile, and the rest consider normal fluctuations.
Heart abbreviations in the norm should occur at the same time intervals, i.e. be rhythmic. Arrhythmia may indicate the presence of a congenital heart disease or hypoxia of the fetus. The heartbeat should sound very clearly and distinctly, with deaf tones, you can suspect intrauterine oxygen deficiency. An important indicator is the frequency of heart abbreviations.
