What is the normal amniotic fluid index in late pregnancy?

When the fetus is in the mother's belly, it lives in the amniotic fluid. This amniotic fluid is the baby's greenhouse in the mother's belly. The baby grows and breathes freely in the amniotic fluid and maintains basic physiological needs. Therefore, the amniotic fluid of pregnant women is very important for the baby. But at the same time, it is also very important for expectant mothers. Therefore, the amniotic fluid index test will always appear in the pregnancy check-up. Next, let’s take a look at what the amniotic fluid index is in the late pregnancy and is considered normal.

What is the amniotic fluid index in late pregnancy?

1. The standard value of the amniotic fluid index in late pregnancy is 8-18 cm. The normal value of amniotic fluid of 3-8CM usually refers to the deepest layer of the amniotic fluid of pregnant women. If the amniotic fluid of pregnant women is lower than 3CM, it indicates that there is too little amniotic fluid, and if it exceeds 8CM, it indicates that there is too much amniotic fluid. Too much or too little amniotic fluid is bad for the fetus.

2. The so-called amniotic fluid refers to the fluid in the amniotic cavity of the uterus during pregnancy. During the entire pregnancy process, it is an indispensable key component to maintain the life of the fetus. The source of amniotic fluid varies during the different development stages of the fetus. In the first trimester of pregnancy, the amniotic fluid of the pregnant woman mainly comes from the plasma components of the test tube embryo; later, as the organs of the test tube embryo begin to develop and perfect, other things such as the fetal urine, respiratory tract, digestive tract, fetal umbilical cord, embryonic surface, etc., also become sources of amniotic fluid.

3. The amniotic fluid index is calculated by adding up the depth of amniotic fluid in four areas: upper, lower, left and right, with the pregnant woman's navel as the center during B-ultrasound. The standard value of the amniotic fluid index in late pregnancy is 8-18 cm. The normal value of amniotic fluid is 3-8cm, which refers to the deepest layer of amniotic fluid in pregnant women. Ultrasound examination shows the vertical depth of the largest amniotic reservoir. Less than 2 cm indicates oligohydramnios, while more than 8 cm indicates polyhydramnios.

The above is the information compiled by the editor about what is considered normal amniotic fluid index in the late pregnancy. From the above information, we can understand the importance of amniotic fluid to the fetus and what it will look like if there is too much amniotic fluid in pregnant women. There are also some data for reference. Based on the above data, expectant mothers can have a certain reference to discuss the condition of the fetus and their own health status. I hope the editor's review will be of some help to you.
