The first NT examination is very important, early Tang screening depends on it, mainly on this value

Want a healthy baby, birth examination is very necessary, but for novice mothers, most of them are still “at a loss” for birth examination. Doctors can check what they want, and they don’t know what the specific use is. < p > < p > Yutong, the mother of the second child, is a bitter tear every time she talks about her birth examination. Because I am also working in the hospital, I know what NT examination means, and I attach great importance to it every time. But every time it’s been through ups and downs. < p > < p > in the year when I was pregnant with my eldest daughter, the value of NT examination was 3.1. I knew that this meant that the risk of fetus becoming “Down’s baby” was very high. At that time, I was very worried. < / P > < p > two weeks later, she made a more accurate non-invasive DNA, and the result was no problem. She was relieved. Only she knew how she had survived those two weeks. Later, she had a cesarean section and gave birth to a girl with a weight of more than 8 kg, and she was healthy all the time. < p > < p > when the baby is 6 years old, Yutong looks at it again and has a second child. At the time of NT check, I didn’t expect that the value was even higher, which was 4.7. < p > < p > after hearing this conclusion, she broke down and cried because she was worried about her baby’s health. Later, on the advice of experts, amniocentesis was performed at 18 weeks. < / P > < p > the examination was very frightening. The most painful thing was waiting for the examination results to come out. After waiting for more than ten days, she called the hospital a lot, but finally, she concluded that it was OK. < p > < p > for pregnant women under the age of 25, the prevalence rate of Taibao was only 0.5 ‰; when the age of pregnant mother was 35, the incidence increased to 3.3 ‰; when the age of pregnant mother was older than 44, the incidence rate was 25 ‰. < / P > < p > many pregnant mothers are confused when they hear the NT test. This test sounds very tall, but how do you feel if you don’t check it specifically, the results come out. < / P > < p > the full name of NT examination is neck transparency thickness, which is the maximum thickness value of transparent liquid at the back of Taibao neck during B-ultrasound examination. < / P > < p > through this value, we can calculate the prevalence rate of “Down’s baby” in Taibao with an accuracy of about 85%, which is an important examination for early Tang screening of Taibao. < / P > < p > however, the accuracy of NT is relatively low. If the value of NT is not very good during the examination of pregnant mother, you can choose to do painless DNA or amniotic fluid puncture for further confirmation. < / P > < p > in fact, the effusion at the back of fetal neck in NT examination is the cervical lymphatic vessels with a small amount of lymph accumulated before the establishment of fetal lymphatic system. < p > < p > by the time the fetus reaches 14 weeks of development, the lymphatic system has formed, and the effusion in the back of the neck will be consumed by the fetus in the process of development. < p > < p > therefore, Baoma, who does not want to miss the NT test of Taibao, must do this test before the 14th week of gestation. Once missed this period, tangshai will be in the second trimester of pregnancy. The best time for NT examination is 11-13 weeks + 6 days, which is OK. 11 weeks when the fetus is too small, scanning when the inspection is more difficult, so it is generally recommended to check at 12 weeks of gestation. < / P > < p > when Tangma’s best friend was doing NT, she tossed about three times because of Taibao’s disobedience. Later, Bao’s father got angry and gave a warning directly across his belly. Unexpectedly, she passed through this way for the fourth time. It’s a treasure of “bullying the soft and afraid of the hard”. < / P > < p > I’m a candy mom. I’m a learning and growing treasure mother. I’m focused on pregnancy and parenting.
