Analysis of normal values for biparietal diameter and femur length at 36 weeks of pregnancy
With the continuous development of medical technology, fetal abdominal ultrasound examination has become one of the important means for pregnant women to prevent pregnancy complications. The analysis of the normal values of the biparietal diameter and femoral length of the fetus at 36 weeks is very critical for pregnant women and doctors. The following will be elaborated on in many aspects such as fetal development and the significance of ultrasound examination.
Fetal Development
Fetal development is a very complex process. A 36-week-old fetus weighs approximately 2,400 grams. The fetal body system has mainly developed, but the growth of the body still needs to continue for a period of time. At this stage, the fetal brain development is in a stable stage, the cerebral cortex is mainly mature, and it can breathe independently.
The significance of fetal ultrasound examination
Fetal ultrasound examination is a non-invasive examination method that uses ultrasound waves emitted by an intrauterine probe to observe the growth and development of the fetus and the abnormalities of various organs. It can also measure the fetal weight, head circumference, body length, abdominal circumference, femoral length, etc. Take measurements. Among them, fetal biparietal diameter, as one of the standards for fetal head development, affects the smoothness of delivery. Fetal femur length is one of the important criteria to measure whether fetal bone strength matches physical development.
Normal values for biparietal diameter and femoral length at 36 weeks
According to the internationally accepted standards for fetal biparietal diameter and femoral length, the normal range of biparietal diameter at 36 weeks is 85 to 104 mm, while the normal range of femoral length is 62 to 76 mm. During a fetal ultrasound examination, the doctor will compare the maternal examination results with the normal range to determine whether the fetus is healthy.
Notes
It should be noted that although fetal ultrasound examination is non-invasive, the health and safety of mother and baby also need to be taken seriously. First of all, the impact and safety of ultrasound on human tissue have not been fully scientifically proven, so too frequent fetal ultrasound examinations are not recommended. Secondly, pregnant women need to prepare relevant examination items according to the doctor\’s instructions before having a fetal ultrasound examination, such as emptying the bladder in advance.
Summary
The normal value analysis of fetal biparietal diameter and femoral length at 36 weeks is very critical for pregnant women and doctors. Ultrasound examination can effectively prevent complications and improve the success rate of fetal birth. Of course, through accurate examination results and correct analysis, doctors can give more scientific and professional advice to help pregnant women better protect the development and health of their fetuses.
