What are the abnormalities in fetal movement in children with Down syndrome? Down syndrome, also known as Mongolian disease, is congenital. Down syndrome is caused by chromosomal abnormalities. In most patients, the 21st pair of chromosomes goes wrong during gene division, resulting in additional chromosomes in the nucleus, with a small portion caused by translocation.
1. Generally speaking, pregnant mothers with Down syndrome have a fetal movement sensation of more than 20 weeks, with less fetal movement, weak ribs, and weak strength.
2. When displaying the face through system color Doppler ultrasound, the distance between the eyes is abnormal.
3. The head is large and the double diameter data is too large, but the development of the limbs is slow.
4. The umbilical blood flow value (S/D in the examination) is abnormally high and has not improved after hospitalization control.
According to reports, the formation factors of Down syndrome are complex, so pregnant women in each age group need to undergo Downs screening, mainly to evaluate the risk index of Down syndrome in the uterus, in order to avoid the birth of children with a history of Down syndrome.
When is the best time for women to undergo Down testing during pregnancy? Experts from obstetrics hospitals say that the best time for women to undergo Down screening is during the 12th to 24th week of pregnancy. It's not too early or too late yet. If the testing time is within 12 weeks, the DNA concentration in venous blood will be too low to meet the testing requirements. If it exceeds 24 weeks and the test results are poor, induced abortion may be necessary, which can cause significant harm to the health of pregnant women. Therefore, pregnant women should pay attention to this.
