How to judge fetal growth restriction?

summary

We all know that the fetus in the mother is only a family of fertilized eggs formed by the combination of sperm and egg. It slowly absorbs some nutrients from the mother and continues to grow and develop, and finally grows into adult type. In fact, this is also the process of pregnancy. However, some fetal growth problems may occur, such as fetal growth restriction. How to judge fetal growth restriction? Next, I'd like to share my views with you.

How to judge fetal growth restriction?

If the uterine length and abdominal circumference were below the 10th percentile for 3 consecutive weeks, the prediction accuracy was above 85%. In the third trimester, the pregnant women gained 0.5kg per week. If weight gain is stagnant or slow, it may be fetal growth restriction.

To evaluate the gestational age and fetal growth, B-ultrasound was used to measure the values of different parts of the fetal body, including fetal head hip length, fetal head biparietal diameter, head circumference, chest circumference, abdominal circumference, femur length and other parameters. 85% fetal growth restriction can be found by HC / AC.

Fetal development index was calculated. Fetal development index = uterine length (CM) - 3 ×( The index between - 3 and + 3 is normal, less than - 3 may indicate fetal growth restriction. The ratio of HC / AC in normal fetuses was more than 1 at 32 gestational weeks and less than 1 after 32-36 gestational weeks; The ratio of fetal growth restriction increased with gestational age.

matters needing attention

Pregnant women during pregnancy must go to physical examination on time, do a good job of prenatal examination, because this can be more timely and accurate observation of pregnant women's physical condition and fetal health and growth. Stop smoking and drinking, and change unhealthy eating habits.
