KTR - what does this mean? CTE of fetus

When a woman is in a special situation, she requires maximum attention from medical professionals. That is why often pregnant ladies are prescribed various procedures, such as, for example, ultrasound diagnosis. In this article I want to understand the abbreviation such as KTR: what it is and how important these figures are.

About the concept

Women in the position are at least three ultrasound for all nine months of bearing crumbs. And they know that at such an examination the doctor determines the various parameters of the baby, including its dimensions. It should be noted that each period of embryo development corresponds to certain indicators, according to which a specialist can say whether the pregnancy is normal. How does an abbreviation such as KTR, what is it? This is the coccyx-parietal size of the child in the womb.

What is it for?

Why do you need to know these figures? They are correlated with the body weight of the crumbs and due to this, the exact duration of pregnancy is calculated (taking into account, of course, the date of the last menstruation). So, in that, KTR - what it is, figured out. Now it is worth mentioning that these indicators are very important up to the 11th week of pregnancy, sometimes even up to the thirteenth. After this time, other indicators come to the fore, according to which it will be possible to determine how correctly the baby develops in the womb of the mother.

Methodology

How can a doctor make such measurements to find out the CTE of the fetus? What does this include? These parameters the medical worker will measure during such procedure, as ultrasonic. However, neither the woman herself nor her child will feel anything at all. The doctor will measure the crumb from the crown to the tailbone, correlate these figures with the table and draw certain conclusions.

It is worth saying that the longer the gestation period, the greater will be the CTE of the embryo. What does it mean? It's simple: the child is growing, and its size is increasing. How will the doctor get these figures? He will need to scan the woman's uterus in different projections, choose the one where the baby is better seen from the point of view of this measurement, and make measurements. If we imagine what the baby is at this time (a certain body in the form of a worm that is slightly bent in a circle), the question arises as to how the doctor can correctly recognize these parameters. Measurements should be made at a time when the embryo is maximized. Also, more accurate results are obtained at a time when the baby has the least motor activity.

Time

It is also important to say when these figures may be known. So, the ideal time for the first ultrasound, when the KTR of the fetus becomes known, is approximately the 11th week of a woman's pregnancy . It is at this time and the main evaluation of fetal growth (the most important indicator during this diagnosis) is carried out, and also the work of his heart is seen. It is also important to say that it is due to these figures that the pregnancy period can be specified. In fact, before that, it is very approximate, since it is based on simple calculations since the last menstrual period. Previously, a woman may be assigned ultrasound diagnosis, if there is some fear of the doctor regarding the life and health of both the mother and the embryo.

Norm

Understanding the KTR abbreviation (what it is and why it is needed), it is also important to say about the normal indicators that should be obtained by this measurement. There are certain tables in which certain figures are written for each week. Checking these indicators, you can find out if everything is fine with a crumb. It is worth saying that until the sixth week of pregnancy, ultrasound is done quite rarely, so often tables begin with the seventh week of life of the embryo. However, a five-week-old child has a size of 5 mm, a six-week-old child has a size of 6 mm. But further this trend will not be preserved, as the baby will grow faster and develop. In the seventh week, the KTP of the baby should be about 10 mm, on the eighth - 16 mm, on the ninth - twenty-three. The deadline for the first ultrasound scan of a pregnant woman is the 14th week. At this time, the CTE of the embryo will be as much as 63 mm! Further, to know this indicator is not so important (and doctors do not attach much importance to this), because in the foreground will come out quite different numbers.

Deviations in the big party

So, in what is KTR, what does this mean, sorted out, also considered the ideal indicators. But unfortunately, this is not always the case. Quite often, the indicators deviate from normal in one direction or another. Generally speaking, too rapid growth of the embryo may indicate that the baby will be large and can weigh up to 4 kg at birth. Also, this may indicate that the period of pregnancy was initially set incorrectly.

Deviations in the smaller side

What indicators can a pregnant woman learn when she does ultrasound? KTP. What it is is understandable. Coccyx-parietal size. However, sometimes there are situations that the figures are slightly lower than those indicated in the table. What can it talk about? Firstly, again, that the original pregnancy period was originally set. Do not be scared, this is often the case early, and later these figures can be adjusted. If the embryo does not grow, it may also indicate that the fetus has frozen in its development, ie, died (it is easy to determine by the presence or absence of cardiac contractions, and also by the movements of the child).

It is not uncommon for a situation when the mother's hormonal deficiency becomes the cause of miscarriage. Violating the growth and development of the fetus can various infectious diseases that can be in the mother's body. This is also worth knowing. The embryo can develop too slowly even if it has certain genetic diseases. For example, Down's disease, Patau, Edwards. The growth of the baby in the womb can also be affected by internal diseases of the woman, cardiovascular problems, as well as thyroid disorders. And lastly, why a child can develop too slowly in the womb - these are various disorders of the mucous membrane of the uterus, which can manifest themselves as a result of previous abortions.
