12 week amniotic fluid depth 24mm normal?

After pregnancy, the pregnant woman's stomach will continue to get bigger. On the one hand, the fetus is growing, on the other hand, amniotic fluid will continue to increase, which will protect and nourish the fetus. However, if some values of amniotic fluid are problematic, it will also lead to serious consequences. So, is the amniotic fluid depth of 24mm normal in 12 weeks?

12 week amniotic fluid depth 24mm normal? At this time, the fetus has been kicking, clenching, turning, squinting and frowning in the uterine cavity. Teeth, lips and genitals begin to develop. The fetus is about 9 cm long and weighs about 28 grams. B-ultrasound tips; Biparietal diameter: 3.0-3.2 cm, humerus: 1.03 cm, femur: 1.56 cm, chest circumference: 6.43 cm, abdominal circumference: 7.4 cm, amniotic fluid index: 7.87 cm.

Amniotic fluid depth is a medical term, which is an important index to judge the amount of amniotic fluid. Before 28 weeks (7 months) of pregnancy, due to more amniotic fluid, the fetus is smaller, the range of fetal movement in the uterine cavity is larger, and the fetal position is easy to change. After 32 weeks (8 months) of pregnancy, the fetus grows rapidly and the amniotic fluid decreases relatively. Amniotic fluid depth refers to the vertical depth of the largest sheep pond indicated by B-ultrasound. In the 24th week of pregnancy, amniotic fluid depth less than 2cm indicates oligohydramnios, and amniotic fluid depth greater than 8cm indicates polyhydramnios. Amniotic fluid index is to divide the uterus into four quadrants, measure the maximum depth of amniotic fluid in each quadrant respectively, and then add up. The total value in the range of 8 ~ 27 cm is normal, less than 8 is oligohydramnios, and more than 24 is polyhydramnios.

Generally speaking, the depth of amniotic fluid in pregnancy 12 weeks is in the normal range of 2 cm to 8 cm, and the activity space of the fetus is relatively suitable in this range, which is beneficial to the growth and development of the fetus. However, if the amniotic fluid depth of pregnant women's friends exceeds this range, it is recommended to go to the hospital to consult a gynecologist and seek a solution.

The fetal condition in different cycles is 1, the fourth month (16 weeks).

At 16 weeks of pregnancy, the hair, eyes, eyelashes and nails of the fetus begin to grow, and the vocal cords and taste buds have grown. The fetus is about 18cm long and weighs 1 13g. B-ultrasound showed that the biparietal diameter was 3.28-3.6 cm, the humerus was 1.75-2.0 cm, the femur was 2.03-2.23 cm, the chest circumference was 8.43 cm, the abdominal circumference was 9.40 cm, and the amniotic fluid index was 10.5 cm.

2. The fifth month (20 weeks)

In the fifth month of pregnancy, the fetal movement began to crack strongly, and the fetus had grown hair and sucked its thumb, and various parts of the body gradually grew. At this time, the fetus is about 25 cm long and weighs 224-500 grams. B-ultrasound showed that the biparietal diameter: 4.47-5.0cm, humerus: 2.57-2.97cm, femur: 3.0 1-3.47cm, chest circumference:1.71-2.

3. The sixth month (24 weeks)

At the 24th week of pregnancy, the eyes of the fetus can be opened and closed, and the voice inside the mother can be heard. The fetus is 29-30cm long and weighs 680- 1000g. B-ultrasound tips; Biparietal diameter: 5.73-6.07cm, humerus: 3.72-4.3cm, femur: 4.2-4.75cm, chest circumference:14.9-16.4cm, abdominal circumference:16.84-/kloc-.

4. The seventh month (28 weeks)

At 28 weeks of pregnancy, the fetal weight increased rapidly, about twice as much as at 24 weeks. The skin is red and slightly wrinkled. The weight is about1150g-1800g, and the body length is 35-42cm. B-ultrasound tips; Biparietal diameter: 6.64-7.0 1 cm, humerus: 4.39 cm, femur: 5.27 cm, chest circumference: 17.37 cm, abdominal circumference: 19.35 cm, amniotic fluid index:15.2-
