Normal amniotic fluid depth at 32 weeks of pregnancy

Amniotic fluid of pregnant women, everyone knows that this refers to the fluid in the amniotic cavity of the uterus during pregnancy. It is an indispensable ingredient for maintaining the nutrition of the fetus during pregnancy. The depth of amniotic fluid is a medical term. It is the vertical depth of the largest amniotic fluid reservoir expressed by B-ultrasound examination. It is also an important indicator to judge the amount of amniotic fluid in pregnant women. So, what is the normal range of amniotic fluid depth when the fetus is 32 weeks old?

32 weeks amniotic fluid depth is within normal range

The depth of amniotic fluid refers to the vertical depth of the amniotic fluid reservoir expressed by B-ultrasound examination. Less than 2cm indicates too little amniotic fluid, and more than 8cm indicates too much amniotic fluid. B-ultrasound examination shows the vertical depth of the larger amniotic fluid reservoir, and the amniotic fluid depth of 3-8cm is the normal amniotic fluid flow. If it is less than 3cm, it indicates that there is too little amniotic fluid, and if it is more than 8cm, it indicates that there is too much amniotic fluid.

The influence of amniotic fluid depth on pregnancy

The amniotic fluid in the pregnant woman's uterine cavity has the regulatory function of protecting the fetus from harm by outsiders. It can also maintain a suitable temperature in the uterine cavity and allow the fetus to have space to move freely. It is very important for pregnant women. The depth of amniotic fluid is also a key indicator to determine how much amniotic fluid a pregnant woman has. Therefore, mothers must attach great importance to checking the depth of amniotic fluid during pregnancy.

If the depth of amniotic fluid is ≥8cm, it means that there is too much amniotic fluid. The effects of too much amniotic fluid on pregnant women mainly include placental abruption, uterine atony, postpartum hemorrhage, etc. Due to excessive amniotic fluid, the fetus has a large range of motion in the uterine cavity, which can easily lead to a transverse position of the fetus; excessive swelling of the uterus and excessive pressure can easily lead to premature birth. If the amniotic fluid of the pregnant woman is discharged after rupture of the membrane, resulting in a decrease in the pressure in the uterine cavity, it may cause early embryo separation. In addition, the pregnant woman's uterus is large, and excessive expansion can easily cause uterine atony, and may also cause the risk of postpartum hemorrhage, all of which have a great impact on the pregnant woman and the fetus.

If the depth of amniotic fluid is ≤2cm, it means that there is too little amniotic fluid. The impact of too little amniotic fluid on the fetus is mainly to increase the perinatal mortality rate, which will cause fetal intrauterine dysplasia, deformity and lack of oxygen. The impact on pregnant women is that it increases the probability of caesarean section.

After reading the editor's article, you will know that the normal range of amniotic fluid depth at 32 weeks is 3-8cm. If it is less than this depth range, it means too little amniotic fluid. If it is higher than this depth range, it means too much amniotic fluid. These conditions will have a great irritating effect on the fetus. Less than this depth will cause developmental malformations and even more serious problems such as fetal death. Prenatal check-up is an indispensable stage for pregnant women.
