What is the standard of biparietal diameter of 38-week fetus?

At 38 weeks, the fetal length is about 47: 5 cm, the weight is 3100 g, the biparietal diameter is 9: 08 0: 59 cm, the abdominal circumference is 30: 63 2: 83 cm, and the femur is 7: 20 0: 43 cm. Let's look at the standard of biparietal diameter of 38-week-old fetus.

38-week fetal biparietal diameter standard

The 38th week belongs to September of the third week of pregnancy, so the standard of fetal biparietal diameter in the 38th week should be more than 9.0 cm 10.0 cm, but the statistics of fetal biparietal diameter are based on the average value, so the average value of fetal biparietal diameter in the 38th week is 9.0810.59.

Dietary considerations in the third trimester of pregnancy

In the third trimester, expectant mothers enter the final sprint stage, and the nutritional storage of mothers is particularly important. A safe, healthy and reasonable diet is a necessary prerequisite for a healthy birth of a fetus. Combined with the nutritional characteristics of the third trimester, we should make corresponding adjustments on the basis of the diet in the second trimester.

A diversified diet

Diversified dietary requirements: In the third trimester, expectant mothers should not only supplement calories, but also pay attention to the supplementation of high-quality nutrients such as protein, clams, calcium and vitamins. They can eat less and eat more meals, which can be increased to more than 5 meals a day. Never take a lot of supplements to avoid obesity and macrosomia (expectant mothers should not gain more than 15 kg during pregnancy).

Supplement calcium and iron

Supplementing sufficient calcium and iron can help the teeth and bones of the fetus to calcify well and prevent the expectant mother from anemia. You can eat more kelp, seaweed, shrimp skin, sesame, animal liver, eggs and fish.

Increase plant protein.

Increase the intake of plant protein, such as beans and bean products.

Reduce foods with high sugar content.

Reduce the intake of foods with high sugar content, such as fruits, sugar and honey. In order to prevent the fetus from growing too big, it will affect the smooth delivery.

Eat more foods with high nutritional value

Eat more foods with high nutritional value and small size, such as animal food; Eat less foods with low nutritional value and large volume, such as potatoes and sweet potatoes.
