how to check the pregnancy B-ultrasound examination list
during pregnancy, pregnant women will undergo 2-3 ultrasound examinations. Do you particularly want to know what the numbers on the report list indicate? Hospital ultrasound reports generally include the following: Fetal sac, fetal head, fetal heart, fetal movement, placenta, femoral, amniotic fluid and spine. What problems do they explain? Under what circumstances are they normal? Under what circumstances are they abnormal? Here are some reference indicators:
1. Fetal sac: the fetal sac is only seen in the early stages of pregnancy. Its size is about 1.5 in diameter at 2 cm months of pregnancy, and about 2.5 is normal at 5 cm months of pregnancy. The fetal sac is normal in the bottom, front wall, back wall, upper and middle of the uterus. The shape is circular, elliptical, and clear. For example, the fetal sac is irregular and fuzzy, and the location is in the lower part, pregnant women may have abdominal pain or ** bleeding, abortion.
2. Fetal Head: the complete contour is normal, the defect and deformation are abnormal, and the middle line of the brain is normal without shift or hydrocephalus. BPD indicates the Double top diameter of the fetal head. It should reach 9.3 cm or more during full-term pregnancy. According to the general rule, after five months of pregnancy, it is basically consistent with the month of pregnancy, that is, when 28 weeks of pregnancy (7 months), BPD is about 7.0 cm, the 32-Week Pregnancy (8 months) is about 8.0 cm, and so on. After 8 months of pregnancy, the average weekly growth of about 0.2 cm is normal.
3. Fetal Heart: normal for "yes" and "strong", abnormal for "no" and "weak. The fetal heart frequency is between and 60 times per minute.
4. fetal movement: fetal movement may be normal, normal, and weak, and the fetus may be sleeping or abnormal. Comprehensive analysis should be carried out in conjunction with other projects.
5. placenta: the placenta is located on the uterine wall. The normal thickness of the placenta is between 2.5 and 5 cm. A Report of calcification is classified into Grade III, level I is the early stage of placenta maturity, and the ECHO is even. This change can be seen in 30-32 weeks. Level II indicates that the placenta is near maturity. Level III indicates that the placenta is mature. The closer the term is, the more mature the placenta, the more uneven the echo.
6. Femoral Length: the length of the fetal thigh bone. Its normal value is about 2-3 cm different from the BPD value in the corresponding month of pregnancy. For example, BPD is 9.3 cm, the femoral length should be 7.3 cm, BPD should be 8.9 cm, and femoral length should be 6.9 cm.
7. amniotic fluid: the amniotic fluid depth is normal between 3-7 cm, more than 7 cm is the increase of amniotic fluid, and less than 3 cm is the decrease of amniotic fluid.
8. Spine: the fetal spine is normal consecutively, the defect is abnormal, and the spine may be malformed.
9. Umbilical Cord: Normally, the umbilical cord should be floating in the goat's water. If the umbilical cord is visible in the fetal neck, it may be around the umbilical cord.

my baby is 32 weeks + 2 days, B-ultrasound data: BPD: 8.9, Femoral Length: 6.8, other data are oversized. Is a big baby. It is 34 weeks now, and the data must be big again. Then my wife and baby will suffer.
