Amniotic fluid index standard mm at 38 weeks of pregnancy

The amniotic fluid of pregnant women is the environmental factor for the growth and development of the fetus in the mother's uterus. The physical and chemical properties of the amniotic fluid of pregnant women will have a great impact on the development of the fetus. The amniotic fluid index can also reflect the condition of the amniotic fluid of pregnant women. B-ultrasound examination shows the vertical depth of the amniotic reservoir. ≤2cm indicates too little amniotic fluid, and ≥8cm indicates too much amniotic fluid. So, let’s take a look at the amniotic fluid index standard at 38 weeks.

38 weeks amniotic fluid index standard

In the late pregnancy, the normal amniotic fluid index is between 80-18b250m, but your result is 53mm. It is recommended to follow up. If it is confirmed, after eliminating the malformation of the fetus, the intrauterine condition of the fetus can be evaluated in detail to promote the improvement of the fetal lungs; when the fetus is perfect, the pregnancy should be terminated as soon as possible. The method of terminating pregnancy can be vaginal induction of labor or caesarean section. The actual choice should be based on the condition of the fetus and the pregnant mother. In this case, most pregnant women can give birth to a healthy baby. For the umbilical artery, it is important to know that the S/D value of the umbilical artery is between 1.7 and 3 during 36 to 40 weeks of pregnancy, and generally does not exceed 3.

Amniotic fluid index: The uterus is divided into four quadrants: upper left, upper right, lower left and lower right. The sum of the vertical depths of the largest dark areas of amniotic fluid in the four quadrants is the amniotic fluid index (AFI). AFI ≥ 25cm is diagnosed as polyhydramnios, among which AFI of 25-35cm is mild polyhydramnios, and 36-45cm is mild to moderate polyhydramnios.
