What is the dimension of secondary ultrasound examination?

During pregnancy, you need to check many times and do various tests continuously to understand how the baby is developing in every aspect. B-ultrasound is the most familiar to us. Some mothers only know what the first-level B-ultrasound check is. In order to continuously understand the baby's development, they should also do the second-level B-ultrasound. So let's follow the editor to understand what the second-level B-ultrasound examination during pregnancy is.

Secondary color ultrasound examination is dominated by two-dimensional ultrasound. The 2012 edition of the Manual of Color Ultrasound Examination during Childbirth clearly states that two-dimensional ultrasound is the equipment that should be configured for secondary color ultrasound examination. Two-dimensional color ultrasound examination should be carried out in accordance with the manual inspection order. First, determine the number and position of the fetus, check the pregnancy period, and then conduct a detailed, orderly, multi-directional, and multi-cross-sectional inspection from the head to the face downward. Although two-dimensional ultrasound can detect fetal major malformations such as damage to key internal organs, its diagnosis rate for some heart malformations is low, so further necessary coordinated examinations should be done.

What does the secondary color Doppler ultrasound check?

1. It can check many organs of the human body, such as the heart, liver, spleen, kidney function, uterus and appendages, bladder, etc. B-ultrasound can see changes in density that are different from normal tissues, such as thickening, cysts, etc. If it is a gynecological examination, B-ultrasound can understand the conditions of the cervix, uterus, appendages, and pelvis.

2. The second-level examination during pregnancy is a graded examination based on the ultrasound image of the embryo observed during the B-ultrasound examination, which represents the growth and development status of the embryo, but cannot represent the function of the placenta. Reminder: The embryos are not yet complete and can be observed again. The assessment of the embryo indicates the maturity of the embryo. Normal early pregnancy is mostly manifested as grade 0, which is the growth and development stage of the embryo. In the middle and late stages of pregnancy, as the embryo matures, the stage develops from level I to level III.

3. The embryo is the nutrient transfer station between the pregnant mother and the fetus, providing the nutrients needed for the normal development of the fetus and excreting metabolic waste. Its effect is divided into three levels: 0-1 indicates that the placenta function is excellent; 1-2 indicates that the placenta function is normal but slightly reduced. Grade 2-3 Grade 3 indicates that placental function is reduced and affects all normal transport. The function of the placenta in the late pregnancy decreases to a certain extent as the fetus grows. Generally, when most pregnant women are about to give birth, the embryos are around level 2-3. Normal conditions will not affect the descent of the fetus and do not require premature delivery. Because the fetus is now fully grown, if a caesarean section is required, the surgery can be performed now.

4. The purpose of screening is to conduct examinations at different levels to determine whether the fetus has congenital defects such as congenital diseases. You can check and understand the detailed situation of the fetus. It is very necessary to do a secondary pregnancy screening. I recommend you to do it. It can check many organs, such as the heart, liver, pancreas, kidney function, uterus and appendages, bladder, etc. B-ultrasound can see changes in density that are different from normal tissues, such as thickening, cysts, etc. If you want to check gynecological aspects, B-ultrasound can understand the conditions of the cervix, uterus, appendages, and pelvis.
