What is the role of B-ultrasound examination during pregnancy? Although expectant mothers all know that B-ultrasound examination is essential during pregnancy, they know very little about the role of B-ultrasound during pregnancy. Next, let’s take a look at the role of B-ultrasound during pregnancy.
The role of B-ultrasound during pregnancy
The purpose of B-ultrasound examination during pregnancy. The purpose of B-ultrasound examination during pregnancy is to determine whether the growth and development of the fetus is consistent with the gestational age, determine whether the fetus has malformations, and understand whether the fetus is safe in the womb. In addition, the purpose of exams in different periods is different. Early B-ultrasound examination is to determine whether the pregnancy, pregnancy position, gestational sac size and menopausal time are consistent, to provide a reliable basis for estimating the expected date of delivery, and to detect abnormalities in embryonic development in a timely manner; the purpose of mid-pregnancy B-ultrasound examination is to observe whether there are abnormalities in the development of fetal tissues and organs. Timely detection of fetal malformations, such as congenital heart disease, anencephaly, hydrocephalus, spina bifida, abdominal wall deformities and other defects, short limbs, polycystic kidneys, gastrointestinal atresia, etc.; the purpose of late pregnancy B-ultrasound examination is to understand the fetal The safety situation in utero provides information for clinical treatment.
The following introduces the meaning of B-ultrasound report terms.
Meaning of terms in pregnancy B-ultrasound report form
Your ultrasound conclusion is generally \”like pregnant**W\”. This means your fetus will look like a normal fetus during the first week. For example, the conclusion \”as pregnant as 24W\” means that your fetus is as long as the normal standard fetus of 24 weeks. Note: It does not mean that the age of your fetus must be 24 weeks, but it means that its size is the same as that of a normal fetus at 24 weeks. Many pregnant women ignore or do not understand this. The size of fetal development is related to genetics, nutrition, and diseases (such as diabetes, etc.). For example, in pregnant women with diabetes, B-ultrasound at 30 weeks of pregnancy (gestational age 30 weeks) indicates that the development of the fetus may be as large as that of a normal pregnant woman at around 36 weeks. On the contrary, when Wu Dalang\’s wife was in the 10th month of pregnancy (40 weeks), the fetus still looked very small, possibly due to genetic factors. After the ultrasound, her baby will probably be about the same size as a pregnant woman at about 32 weeks. W stands for week, which means week in English.
According to the report, BPD refers to the fetal biparietal diameter, which reflects the transverse diameter of the fetal head. For example, if the biparietal diameter exceeds 98.99 mm, the baby\’s weight is likely to exceed 8 pounds. FL refers to the length of the femur (thigh). The fetal positions LOA, LOT, LOP, ROA, ROT, and ROP are all normal, indicating that the fetal head is downward (L is left, O is head, A is front, T is transverse, P is back, and R is right, all are English abbreviations) . I had stomach pain before. Before the baby was born, as long as the fetal head was facing down, the doctor said the fetal position was correct. Note that only LOA or ROA can be born at the last moment of a normal natural birth (at the end of a natural birth, the fetal head must be facing down, and the child\’s eyes are facing the back of the mother\’s body. The child looks like the head is lower, so there is a chance for a smooth delivery.) Please note , your baby\’s head will still rotate at birth. Therefore, pregnant women only need toIt is normal for the fetus to be head-down.
Amniotic fluid. After 28 weeks in the late stage, the amniotic fluid was measured from 4 locations (with the navel as the boundary, 4 locations). 23/24/25/22/26 means that the amniotic fluid volume in each quadrant is 23, 24, 25, and 26 mm, and the total is generally between 80-180. Less than 80 means oligohydramnios, less than 50 means oligohydramnios. Anything greater than 180 is called polyhydramnios. Both doctors and patients should pay attention to the fact that abnormal amniotic fluid may affect mother and child.
You can see a U-shaped mark on the back of the baby\’s neck, indicating that your baby may have an umbilical cord around his neck. Note that this is only possible. About 10% of affected fetuses have this phenomenon. The umbilical cord is wrapped around the neck and I always wear scarves for us, which is generally common and generally has nothing to do with it. If this phenomenon occurs, neither doctors nor patients have a particularly good way to untie the scarf. Common treatment: Pregnant women should pay close attention to fetal movement. If there is an abnormal increase or decrease, they should go to the hospital for rescue in time. Generally, if the umbilical cord is wrapped around the neck 1-2 times and the baby shows no signs of hypoxia, you can try to give birth naturally.
