The most accurate method to know the growth of the baby, you can use the method of ultrasound diagnostics (sonography). During normal pregnancy ultrasound do on 12, 22 and 32 weeks. Ie it is on these test screenings, you can learn about the growth ofe and the weight of the unborn child. However, here too there are subtleties, for example, up to 20 weeks of pregnancy the growth of the fetus is measured from crown to tailbone. This is due to the fact that until about 20 weeks crumbs the legs bent at the knees, and measuring them is almost impossible. Therefore, the growth of the fetus at this period is denoted as, kopcik - parietal size or the abbreviation CTE. If you want to know the growth of your baby, look at the results of the latest ultrasound and find this abbreviation, and it will be considered the growthof om baby.
After 20 weeks of pregnancy growth of the baby is measured from head to toe. It ranges from 26 to 52 cm depending on the period. However, ultrasound can also be wrong. There are cases when an ultrasound before birth showed the growth of the fetus, for example, 50 cm, and a baby born in the same day was 52 see Errors in the measurements can be associated with outdated equipment and inexperienced doctors, who conducted the study.
Also to see the growth of the fetus, you can use the standard tables that contain information about the child's development during pregnancy. In these tables a great variety, you can find them, pgrowthon entering a search query. Relevant data also can be found in the literature about the pregnancy. If you are unable to learn about the growth of thee fetus on your period, you can inquire about it at the training courses for childbirth or the doctor that you are watching. However, remember that each person is different, even when he is in the belly of the mother, so standard tables can be taken only as a basis, but not the fact that your child will exactly this growthand, as it is written.
Advice 2: How to know the size of the fetus
Determination of the size of the fetus during pregnancy – a necessary procedure performed by a gynecologist. This is done in order to evaluate the possibility of participation of the child in the process of labor.
You will need
- - consultation of the gynecologist;
- - Fetal ultrasound
Contact your gynecologist. He will measure your belly from the pubic bone to the top part of the uterus. The resulting value is called the fundic size. This way you can accurately determine what will be the baby big or very small. Midwives, determining the size of the fetus (normal, large, small) use several formulas, one of which is abdominal circumference (in cm) is multiplied by the height of the uterus (in cm).
In addition, after you will be on the account in female consultation, your doctor will certainly check the condition of the placenta, which will also be judged on the size of the fetus. Due to improper activity of the placental unit may develop hypoxia, which leads to slow development and growth of the fetus and require medical intervention.
Pass ultrasound examination of the fetus, it much more accurately defines the size of the child. Scientists hundreds of times the ultrasound was conducted at different stages of pregnancy, the purpose of which were: the definition of the size of the fetus and calculating the estimated average size of baby at each week of pregnancy. The resulting measurement graphs of the average weight are considered the "gold standard", which determines a small child or large.
Consider the genetic factor. Usually, the growth of a boy driven by the growth of his father or close relatives (uncle, grandfather), on the growth of girls influences the growth of the mother and the nearest relatives on the maternal side.
Take into account that the growth and size of the fetus – not quite the same thing. To determine the size of a child can be after one ultrasound. The doctor will examine the fruit, will produce relevant measurements and compare their results with averages. To establish how the baby grows, you need to do ultrasound examination at least twice, with an interval of not less than two to three weeks.
Remember that each pregnancy is individual. And if the fetus has any specifics, that's not a reason to panic. Pass additional tests, refer to another specialist.
Advice 3: How to determine fetal abnormalities
Early diagnosis of pathologies of the fetus with each passing year becomes more and more reliable. It is carried out as a public women's consultation in the framework of compulsory health insurance and private clinics. When such risk factors as hereditary diseases among relatives or age pregnant over forty years, the question of the exclusion of the presence of pathologies of a fetus should be treated particularly seriously.
You will need
- - regular supervision by a obstetrician-gynecologist.
During pregnancy try time pass ultrasonography (us). At a minimum we recommend three treatments during pregnancy at 11-14, 20-24 and 30-34 weeks obstetric. There are several signs, which may indicate the presence of chromosomal pathology in fetus: increased nuchal translucency, fast or slow heartbeat, abnormalities in the structure of the heart, too small size of the maxillary bones, and many others. These signs do not mean that the fetus has a genetic disorder, but those results ultrasound is attentive to the issue of appointment of additional surveys.
Simultaneously with the ultrasound in the first and second trimesters of pregnancy pass a screening blood tests. In the course of these studies takes into account the levels of various factors in serum and other indicators, such as maternal age, presence of harmful habits, weight, indicators ultrasound of the fetus. From the lab results come in the form of calculated probability of the presence of certain abnormalities in the genome. At high values, discuss with your doctor the need for surveys with greater accuracy.
If you suspect the presence of abnormalities of the fetus , you can go through the procedure of chorionic villus sampling, amnio -, or cordocentesis. All these tests aimed at the direct study of the chromosomes of the fetus and detection of certain genetic abnormalities. The accuracy of this procedure is quite high. The fence material for analysis occurs in the fetus, from the amniotic SAC (amniocentesis), umbilical cord (cordocentesis) or villus of the placenta. Because it anyway there is damage to the membranes of the embryo, increases the risk of spontaneous abortion: it should take into account when making decisions.
In these studies, like ultrasound and screening for markers of blood serum, there is a high probability of error, therefore it is recommended to repeat the examination. It is advisable to use the services of different labs and specialists. Anyway, to conclude the presence of abnormalities in the fetus only at these indicators, it is not necessary.
