Normal range of amniotic fluid depth at 30 weeks

Normal range of amniotic fluid depth at 30 weeks

3 Pregnant women all know that the amount of amniotic fluid in the abdomen will also affect the fetus, so every time a pregnant woman has a checkup, she will ask the doctor whether the amniotic fluid is normal. But what is actually normal? Many people want to know, especially at 30 weeks. So, what is the normal range of amniotic fluid depth at 30 weeks? Let’s learn about it together below.

At 30 weeks of pregnancy, the mean biparietal diameter of the fetus was 78.3 ± 6.2 mm, the mean abdominal circumference of the fetus was 248.8 ± 20.3 mm, and the mean femoral length was 57.7 ± 7.47 mm. Although they were all within the mean, the biparietal diameter and abdominal circumference of the fetus were both released within the mean. In addition, judging from the results of the amniotic fluid of the pregnant woman, the pregnant woman has a little too much amniotic fluid. In the late pregnancy, the normal amniotic fluid index is between 80-18b250m, and the amniotic fluid depth is between 30-7b250m. The amniotic fluid flow changes during pregnancy. After 30 weeks of pregnancy, the amniotic fluid index (the sum of the amniotic fluid levels measured in the four quadrants of the abdomen) should be between 10 and 20 cm. If it is less than 8 cm, it is too little amniotic fluid, and if it is less than 5 cm, it is too little amniotic fluid. If there is too little amniotic fluid in the middle and late stages of pregnancy, the pregnancy should be terminated immediately to prevent poor placental function from causing the fetus to die in the uterine cavity.

When there is too little amniotic fluid during pregnancy, the amniotic fluid of the pregnant woman becomes thick, turbid and dark green. The pregnant mother's abdomen is very sensitive and uterine contractions are prone to occur; during prenatal examinations, the uterine height and fetal abdominal circumference are lower than those of mothers of the same gestational age, and the fetus's movement in the uterus is restricted. If the amniotic fluid index is found to be lower than 8 cm during color Doppler ultrasound examination, it is a sign of oligohydramnios. Because too little amniotic fluid can easily lead to intrauterine fetal death during pregnancy and fetal distress during delivery, it increases the difficulty of surgery and seriously affects the difficulty of raising the baby, so it is paid attention to by gynecologists.

I believe that pregnant mothers have a full understanding of the normal range of the depth of amniotic fluid at 30 weeks. If the amniotic fluid of pregnant mothers is normal, they don't have to worry, because pregnant mothers need to maintain a good mood to be good for the fetus. You should do some exercises in the later stages of pregnancy so that you can give birth to your baby quickly when you choose natural delivery.
