37 weeks of pregnancy fetal biparietal diameter and femur length standard

At 37 weeks of pregnancy, the fetus's biparietal diameter and femur length have certain standards, and the biparietal neck is generally around 7.0 cm. During pregnancy, many pregnant women are concerned that the biparietal diameter of the fetus is too large, which can easily lead to dystocia. However, if the biparietal diameter is relatively small, it generally indicates that the fetus is malnourished. In fact, there is no need to worry about this. It can be cured through good conditioning and regular check-ups.

37 weeks of pregnancy fetal biparietal diameter and femur length standard

Many first-time mothers are not clear about what the biparietal diameter of the fetus is. This is also an item that needs to be checked during B-ultrasound. Many mothers will have this question: Why do we need to check the biparietal diameter? What is the biparietal diameter? What happens if the biparietal diameter does not meet the standard?

The biparietal diameter refers to the length of the widest part between the left and right sides of the fetal head, also known as the "greater transverse diameter of the head." When taking an ultrasound, you can see the baby's biparietal diameter. The biparietal diameter will change during each pregnancy. Generally, after the fifth month of pregnancy, the value of the biparietal diameter will be consistent with the month. For example, in the seventh month of pregnancy, the biparietal diameter of the fetus is 7.0cm, and in the eighth month of pregnancy, the biparietal diameter of the fetus is 8.0cm.

What is the use of knowing the biparietal diameter? The purpose of measuring the biparietal diameter is to understand the baby's development, and there is a standard for the biparietal diameter. If the standard is not met, there may be something wrong with the baby's head. Measuring the biparietal diameter can also tell you the baby's position and whether the baby will be born naturally.

There is a biparietal diameter standard for each pregnancy. If the biparietal diameter value is within the standard value, it means that the baby is developing well and is playing happily in the belly. If it does not meet the standard or exceeds the standard, then there may be a problem with the baby's head. If it is too large, it may be water accumulation, and a drainage operation should be performed in time.

What is the standard biparietal diameter of a 37-week fetus?

After learning about the biparietal diameter, many mothers would like to know whether the baby's biparietal diameter will affect future delivery, because babies born naturally are healthier and their development will be more complete after being squeezed during delivery. In addition, they are also worried that an abnormal biparietal diameter means that the baby's development is unhealthy. Even Earthlings can’t stop mommy anxiety attacks. Since there is a standard for fetal biparietal diameter, what is the standard value of fetal biparietal diameter at 37 weeks?

37 weeks is 9 months plus one week. Generally speaking, the biparietal diameter of the fetus in September is relative to the month, which means that the biparietal diameter of the baby in September is 9.0cm. But this is just an approximate value. The professional value is: the average biparietal diameter of the fetus at 37 weeks is 9.00±0.63. That is to say, at 37 weeks, the baby's biparietal diameter is 9.0cm, the error is controlled within 0.63, and the range is between 8.37 and 9.63. If the baby's biparietal diameter is within this range, it is normal, which means the baby is developing healthily.

What to do if the biparietal diameter of the fetus is too large at 37 weeks

The days of pregnancy seemed so long, yet also went by so quickly. Before I knew it, it was 37 weeks, and the baby had already spent 259 wonderful days in my mother's belly. In the blink of an eye, the baby is about to be born, and the mother's nervous feeling comes back to her. At this time, every mother would pray that everything goes well, but after going to the hospital for an ultrasound, it was found that the baby's biparietal diameter was too large. The previous calm was broken again. I was really nervous. It would be terrible if the baby had an accident at this time. Why is my baby's biparietal diameter larger? What should I do?

There are two reasons why the baby's biparietal diameter is relatively large. One is that the mother is well-nourished. The baby absorbs whatever the mother eats. If the baby absorbs more nutrition, he will gain weight. My mother is so irresponsible. She eats so much but doesn't do any exercise to burn off the fat. The second reason is that it is heavy, which may be due to water accumulation in the baby's brain. This situation is not good and a brain drainage operation needs to be performed in time.
