Why do we need to do four-dimensional ultrasound?
Obstetric examination is the necessary homework of pregnant mothers during pregnancy, many pregnant mothers pregnant to a certain period of time the doctor will let pregnant mothers go to do four-dimensional ultrasound, perhaps some pregnant mothers will think that usually have been regularly go to do the examination, four-dimensional ultrasound is not necessary to go to do it again, but in the birth of an unhealthy baby after the repentance of the beginning.
Some pregnant mothers are wondering, what is 4D ultrasound? Why is it necessary to go for a 4D ultrasound during pregnancy and what are its functions? What should I pay attention to when I go to do ultrasound? Below, I will give you a detailed introduction.
What is four-dimensional color ultrasound
The full name of four-dimensional color ultrasound is four-dimensional color ultrasound diagnostic instrument, is a modern advanced color ultrasound equipment. Four-dimensional color ultrasound is able to surface imaging, more clear screening of fetal limb development whether malformation, meningeal bulge, whether cleft lip and palate, spina bifida and other congenital anomalies, early detection and early solutions.
The role of four-dimensional ultrasound for pregnant mothers and babies
Determine the due date
The best 4D ultrasound examination is recommended around the 22nd to 28th week of pregnancy, because during this period the structure of the fetus has been basically formed, the amniotic fluid is also well stocked, and the size of the fetus is developing just right, with more room for intrauterine activities, it is relatively easy for 4D ultrasound to capture, and the images are clearer, which makes it easier for the doctor to discover more developmental problems of the fetus in a timely manner.
Checking the activity of the fetus
It can check whether the fetus lacks oxygen in the uterus, limb movement, swallowing movement of the fetus, etc. It can see the activity of the fetus in the mother’s body very well.
Monitoring Fetal Growth and Development
Doctors explain that the detection of fetal development is based on the measurement of the value of the fetus, if it is below the 10th percentile, or above the 90th percentile, the fetus is abnormal.
Fetal abnormalities
Ultrasound is an important tool for detecting fetal abnormalities. Once a fetal abnormality is detected, the pregnancy can be terminated promptly. Usually, ultrasound can be done at 22-26 weeks of pregnancy to check whether the fetus is malformed or not, because all the organs of the fetus have been developed at this time, and it is easier to see whether there is any malformation or not. Therefore, it is very important to have an ultrasound.
Measurement of amniotic fluid
Color ultrasound can accurately measure the amount of amniotic fluid. The amount of amniotic fluid in the mother’s body is very important to the development of the fetus, because too much or too little amniotic fluid can lead to fetal malformation. In the ultrasound, it can also clearly understand whether the position of the placenta is normal or not, whether the placenta has the presence of hemangiomas, whether it is mature or not, etc. It can clearly diagnose the presence of placenta praevia, placenta previa and other dangerous conditions.
What to pay attention to when doing four-dimensional ultrasound
1, generally throughout the pregnancy to do three four-dimensional ultrasound, pregnant 22 ~ 26 weeks to do four-dimensional ultrasound best, but the specific time is also different from person to person.
2, pregnant women in the stage of 22-26 weeks, do four-dimensional ultrasound do not need to hold urine, also do not need to empty stomach. Pregnant women only need to go to the hospital within the specified time for the examination.
3、Before the 4D ultrasound examination, pregnant women had better wear their tops and pants separately. In the four-dimensional color ultrasound examination, the doctor is mainly through the examination of the instrument, the fetus’s current facial development, as well as the heart, the brain, the spine and so on there is no developmental defects for a check.
4, do four-dimensional ultrasound, pregnant mothers must maintain a good state of mind, the entire examination process will last about 20 minutes.
