Amniotic fluid index standard mm at 30 weeks of pregnancy

At 30 weeks of pregnancy, the pregnant woman has entered the late stage of pregnancy. The fetus at this time has already become larger. As the fetus grows, the depth of the amniotic fluid will also change. So what is the standard for the depth of amniotic fluid at 30 weeks of pregnancy? This article will introduce the relevant professional knowledge of the depth of amniotic fluid and talk about what is the standard for the depth of amniotic fluid at 30 weeks of pregnancy?

1. What does the depth of amniotic fluid mean?

The depth of amniotic fluid refers to the vertical depth of the amniotic fluid reservoir when a pregnant woman undergoes an ultrasound examination during pregnancy. It is a key indicator value used to determine the amount of amniotic fluid in a pregnant woman. The normal depth of amniotic fluid is 3-7cm. If it is ≥8cm, it indicates that there is too much amniotic fluid. When there is too much amniotic fluid, pregnant women are prone to complications of pregnancy-induced hypertension, placental abruption, abnormal fetal position, and increased incidence of premature birth. If it is ≤2cm, it indicates that there is too little amniotic fluid. Too little amniotic fluid can cause meconium deposition during the delivery period of the fetus, and even premature birth or asphyxiation. Therefore, it is very important to control the depth of amniotic fluid for the baby's development.

2. The impact 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.

3. Amniotic fluid depth standard at 30 weeks of pregnancy

The amniotic fluid depth of 31mm at 30 weeks of pregnancy is normal. It is normal between 20-8b250m. Less than 2b250m is oligohydramnios, and more than 8b250m is polyhydramnios. According to the sum of the four quadrants, the amniotic fluid index of 113mm is also normal. Between 80-180 is also normal. Pay attention to regular prenatal checkups and pay attention to the baby's fetal movements.

The article explains in detail what amniotic fluid depth is, the impact of amniotic fluid depth on pregnancy, and also introduces in detail the standard of amniotic fluid depth at 30 weeks of pregnancy. If you are a pregnant woman, if you want to give birth successfully, you'd better pay attention to the amniotic fluid depth and find out what is the normal amniotic fluid depth.
