Biparietal diameter and femoral length standard at 30 weeks of pregnancy

The 30th week of pregnancy is the stage when the pregnancy reaches seven and a half months. At this time, the pregnant woman has also entered a very important stage. If she can get through this stage, she can give birth to a smart and beautiful child. At 30 weeks of pregnancy, female friends also want to know the current condition of the fetus. What is the general length of the biparietal diameter of the femur at 30 weeks of pregnancy?

What is the biparietal diameter of the femur at 30 weeks of pregnancy?

Under normal circumstances, at about 30 weeks of pregnancy, the biparietal diameter of the fetus is 79mm, the femoral head length is about 56mm, and the average abdominal circumference of the fetus is: 248.8±20.3mm. The biparietal diameter of the fetus refers to the length of the widest part between the upper and lower sides of the fetus's head, also known as the "great transverse diameter of the head." Also known as BPD, doctors often use it to observe the baby's development, determine whether there is cephalopelvic disproportion, and complete delivery of pregnant women.

How much is the standard for the depth of amniotic fluid at 30 weeks of pregnancy?

At 30 weeks of pregnancy, the depth of amniotic fluid should be around 5CM. After 30 weeks of pregnancy, the amniotic fluid index (the sum of the amniotic fluid levels measured in the four quadrants of the abdomen is the amniotic fluid index) should be between 10 and 20 cm. If it is less than 8 cm, it is too little amniotic fluid, and if it is less than 5 cm, it is too little amniotic fluid. If there is too little amniotic fluid in the middle and late stages of pregnancy, the pregnancy should be terminated immediately to prevent poor placental function from causing the fetus to die in the uterine cavity. If there is little amniotic fluid, you should drink more water and have regular follow-up ultrasounds.

If you do a prenatal check-up at 30 weeks of pregnancy, you will naturally know the current size of the fetus, whether it is normal, and so on. It is recommended that in the middle and late stages of pregnancy, in addition to regular prenatal checkups, you should also pay attention to your own health. If you have any uncomfortable symptoms, you should pay attention to it in time and take serious measures.
