The elderly often say that the first three months of pregnancy are very important, and many unstable factors will occur during this period. But after these three months, mothers can go to the hospital to establish files after entering the middle of pregnancy, and it will also be accompanied by B-ultrasound examination.
But the report after the examination has to be answered by the doctor. Maybe after finding a doctor, many pregnant mothers will not be relieved, and they have to ask other doctors more. Sometimes a lot of professional terms can make pregnant mothers confused, and behind the incomprehension, there is more anxiety.
If pregnant mothers can’t wait to know the baby’s condition, they can learn to understand the important data on the B-ultrasound order by themselves, so they will feel much more at ease.
The ultrasound examination at 3 months of pregnancy is very simple and it will not take a long time. It will be over in the laboratory for a few minutes and the doctor will be able to perform the test speed very quickly. Then I waited for the ultrasound order to come out and interpret the above data.
points out the key points here. There are 2 specific period data in the list, which is the data that will only appear during pregnancy tests. It is very important and will not be displayed after this stage. If you understand these two data on the B-ultrasound order, you will know the "little secret" of the fetus.
1. 2 specific important data on the B-ultrasound order
1. Head and hip length
The fetal head at three months of pregnancy is still relatively small, showing about 5cm. Moreover, the fetus is curled up in the mother, which also brings certain difficulties to measuring the double parapetal diameter and femoral length , so the hip length is usually measured, referred to as CRL. The head and hips are medically long and usually refer to the distance between the top of the fetal head and the bottom of the hip.
3 standard data on head and hip length around the three-month pregnancy period can refer to the following data:
10 weeks of pregnancy: 32.7mm-41.4mm
11 weeks of pregnancy: 43mm-52.9mm
12 weeks of pregnancy: 54.7mm-65.9mm
13 weeks of pregnancy: 67.8mm-80.2mm
12 weeks of pregnancy: 67.8mm-80.2mm
12 weeks of pregnancy: 43mm-52.9mm
12 weeks of pregnancy: 64.7mm-65.9mm
13 weeks of pregnancy: 67.8mm-80.2mm
12 weeks of pregnancy can be used to calculate the fetal gestational week, gestational week = CRL (cm) + 6.5. For example: If the head and hip length is 3.9 cm, then the gestational week = 3.9+6.5=10.4 weeks.
2.NT check
This test is closely related to the chromosome of the fetus. Under normal circumstances, it can be used as a screening indicator for Down syndrome . In layman's terms, NT inspection refers to measuring the size of the space of the transparent layer behind the baby's neck.
The normal effusion size will protect the fetus' brain. For the NT value standards, there are slight differences at home and abroad. Foreign countries use 3mm as the basis, which is normal if it is less than this benchmark; domestic countries use 2.5mm as the basis, which is normal if it is less than this benchmark.
The lower the detection value of NT, the smaller the probability of suffering from Down syndrome, and this will be easily passed. If the value is too high, it means that the risk of suffering from Down is high, accompanied by other symptoms, intestinal malformations, heart abnormalities and other problems.
Of course, the probability of Down is also related to the age of the pregnant woman, and the risk is also high. If it is too high, don’t worry too much. Most of them will be transient lesions of the fetus and will not last for too long. In the end, they will slowly return to normal levels.
2. Other data to know on the B-ultrasound order
1. Heart rate
When the pregnancy is 3 months old, the fetal heart already has some functions, and the heart rate can be detected by the B-ultrasound. However, the fetal heart rate index is not very stable at this moment. Some are particularly high and can reach 180 beats per minute. These are all small problems. After the fetus grows slowly, the heart rate will gradually return to normal.
2. Amniotic fluid index
The survival environment of the fetus is inseparable from the mother's amniotic fluid. When the pregnancy is 3 months, the amniotic fluid in the abdomen is about 30ml. At this time, the B-ultrasound test will detect the depth of the amniotic fluid. As stated in "Observation Science" , they are within normal categories within 2-8cm.
3. Development of fetus
At this time, the fetus began to have human shape, thin villi grew on the skin, nails grew on the fingers, and the iris of the eyes gradually began to develop, even if the small eyes were still closed.The head and body ratio gradually coordinate. At this time, the fetus will already suck its fingers, its hands and feet will also cross and swing, swallow amniotic fluid, and yawn.
Moreover, after this stage, the probability of fetal malformation will be greatly reduced, and everyone can openly and openly disclose the good news about the baby.
