38 weeks biparietal diameter 94 head big?

The baby's biparietal diameter refers to the widest length of the upper and lower sides of the baby's head. It is an important data for judging the delivery of the baby. It is also an indicator for judging whether the baby's head is fully developed. The biparietal diameter of the fetus is different at each stage of pregnancy, so it is very important to understand the range of the fetal biparietal diameter of the fetus.

What is the size of the fetus's head when the biparietal diameter is 94 at 38 weeks of pregnancy?

1. 38 weeks of pregnancy: The mean biparietal diameter of the fetus is 9.08±0.59.

2. Therefore, a biparietal diameter of 94 in a fetus at 38 weeks of pregnancy is normal.

What is the range of each fetal biparietal diameter according to the gestational week?

1. In the late pregnancy, the biparietal diameter of the fetus generally increases by 0.2 cm per week, and when close to full term, it may increase by about 0.1 cm per week. The length of the femur generally increases by about one to two centimeters per week.

2. When the baby is full-term, BPD should be 9.3 cm or above. According to general regularity, after the fifth month of pregnancy, it is basically consistent with the pregnancy phase. In other words, the BPD is about 7.0 cm at the 28th week of pregnancy (7th month), about 8.0 cm at the 32nd week of pregnancy (8th month), and so on. After 8 months of pregnancy, the average weekly increase of about 0.2 cm is normal, among which the standard biparietal diameter of the fetus at 36 weeks is 8.81 ± 0.57.

3. The biparietal diameter of the fetus is usually measured by ultrasound. As the fetus grows older, the skull continues to grow. When measuring the biparietal diameter of the fetus, it is necessary to measure from the inner edge of the skull on one side to the edge of the skull on the same side. This value is relatively accurate. If the hospital, doctor, and equipment used for the examination are different, the value may also have errors.

Prenatal check-up is an important way to observe basic indicators of the fetus. If any abnormalities are found in the biparietal diameter of the fetus during the prenatal check-up, the expectant mother should not panic, but should immediately consult the attending physician for advice and cooperate with the attending physician's review. There is often a reason why the fetus's biparietal diameter is slightly larger than normal. Finding the reason and preventing it is the most important thing.
