During prenatal check-ups, the growth and development of the fetus can be checked through B-ultrasound, and the size of the baby will also be marked. Therefore, when doing regular prenatal check-ups, it is not only to check the physical condition of the pregnant mother and the growth and development of the fetus, but also to meet the curiosity of the expectant mother. Then let’s talk about the standard correspondence table of fetal humerus length? Standard correspondence table of fetal humerus length 1. At 13 weeks, 1.17±0.31, 6.90±1.65, and 2.52±0.25. At 15 weeks, 1.74±0.58, 9.13±1.56, 3.23±0.51. 3.62±0.58. At 18 weeks, 2.71±0.46, 12.41±1.89, and 4.25±0.53. At 20 weeks, 3.35±0.47, 14.80±1.89, and 4.88±0.58. 2. 22 weeks, 3.82±0.47 16.70±2.23 5.45±0.57. 26 weeks, 4.87±0.41 21.62±2.30 6.68±0.61. 30 weeks, 5.77±0.47 24.88±2.03 7.83±0.62. 3. At 32 weeks, 6.43±0.49, 26.20±2.33, 8.17±0.6. At 34 weeks, 6.62±0.43, 27.99±2.55, 8.61±0.63. At 39 weeks, 7.34±0.53, 31.34±3.12, 9.21±0.59. At 40 weeks, 7.40±0.53, 31.49±2.79, 9.28±0.50. What factors affect fetal femur length? 1. Data errors, different fetal postures, and the actual operations of different doctors all cause deviations in the fetal femoral length data information. Solution: After 30 weeks of pregnancy, the fetal femur length is allowed to vary by two weeks. As long as it is within this range, expectant mothers do not need to worry too much. 2. The fetus is underdeveloped. The fetus's underdevelopment will also affect the length of the fetus's femur. Solution: Pregnant women should monitor the health of their babies and themselves. If they have irregular abdominal pain, spotting during pregnancy, etc., they should go to the hospital for examination in time. 3. Genetic factors. The genetic factors of the fetus will also affect the length of the fetus's femur. For example, some fetuses have congenitally long femoral heads due to genetic factors, which in turn affects the baby's growth. Solution: When encountering this kind of situation, after the newborn is born, try to let him eat more milk, supplement more high-quality protein, and increase physical exercise, which is very helpful for the baby's height. 4. Calcium deficiency. Calcium deficiency during pregnancy may affect the length of the fetus' femur. Solution: During pregnancy, pregnant mothers should supplement high-quality protein and high-quality protein as much as possible, and eat more foods containing high-quality protein in their diet, such as milk, lean pork, big bone soup, etc. In addition, pregnant women should get more sun exposure, which is beneficial to the digestion and absorption of calcium. The standard correspondence table of fetal humerus length has been given above. Expectant mothers who are not sure can refer to it. In fact, there may be problems with the growth and development of the fetus. Most of these problems are due to genetic factors or congenital malformations. These are very common problems, so expectant mothers must prevent them in advance. |
