• # How to determine the weight of the fetus?

February 20, 2013

Perhaps there is not a single future mother in the world who, in the state of pregnancy, did not want to know how much her baby would weigh. Of course, the time of pregnancy is quite difficult from a physiological point of view, but from a psychological point of view, it is a very pleasant and joyful state. The article will discuss how to calculate the weight of the fetus.

## Stroykov Formula

To begin with, there are different formulas for calculating the weight of the fetus. These formulas were developed by different scientists.

So, according to the Stroykovoi method, the formula for calculating the weight of the fetus would be:

X = (MB: K + OJ * VDM) / 2

In the formula X means the calculated weight of the fetus, MB is a reduction - the body weight of the pregnant woman, OJ is the abdominal circumference, VDM is a contraction from the height of the uterus bottom over the womb, and K is a constant.

X value is measured in grams, MB is measured in kilograms, and coolant and GMR are measured in centimeters. The value of K depends on the weight of the mother. If the mother has a mass of up to 51 kg, then K is equal to 15; if the body weight is 51-53 kg, then K is 16; if the MB is between 54 and 56 kg,then K = 17; if the mother’s body weight is between 57 and 62 kg, then K is 18; if the weight of the pregnant woman is in the range of 63-65 kg, then K will be equal to 19; if MB = 66-73 kg, then K = 20; if MB = 74-81 kg, then K = 21 and if MB is more than 82 kg, then K will be equal to 22. If we calculate the weight of the fetus by this formula, then there is an error within two hundred grams.

## Formula Yakubova

Now about how to determine the weight of the fetus by the formula Yakubova. Here, the height of the bottom of the uterus is added to the abdominal circumference, then the indicator is divided by four and multiplied by 100.

## Formula Rudakova

Rudakov proposes this approach to determining the mass of the fetus: it is necessary to measure the semicircle of the width and length of the palpated fetus, and then multiply them. As a result, the resulting figure is substituted into a table developed by the scientist, and determine the mass of the fetus. It should be said that there are three columns in the table where this index can be substituted. These columns represent values ​​for genera of large, premature, and full-term fetuses.

In addition, there are norms of fetal weight. But it should be said that each fruit has its own norm and grows according to its own rules, so to speak. Usually many different tables offer indicators that reflect some kind of averaging.
