Lingering: Genius Baby Sweetheart Mom

Di Chajie's Difficult Choice 【47】

If it is not a marriage of close relatives, B-ultrasound examination for ordinary pregnant women is an important means to find fetal malformations. Generally, B-ultrasound screening can be done at 18-20 weeks of pregnancy, because at this time the various organs of the fetus have developed and formed, and B-ultrasound can be used for screening. Deformities are easily seen.Such as digestive tract malformations, neural tube defects, such as anencephaly, spina bifida, etc.Using a clear-cut B-ultrasound machine, it can even diagnose small fetal limb deformities, such as cleft lip and palate deformities!

However, B-ultrasound is used to check for abnormalities, and dementia and other hidden diseases require other methods.

Of course, Yun Hanxiao had a color Doppler ultrasound at Situ's house, so the baby didn't have any deformities in appearance.Di Chajie also asked Yun Hanxiao to do a Tang's screening at Situ's house! !

Screening for Down's syndrome is a method of detecting the concentration of alpha-fetoprotein and chorionic gonadotropin in maternal serum by extracting serum from pregnant women, and combining the expected date of delivery, age, weight, and gestational week of the pregnant woman to calculate the number of children born with Down's syndrome. The detection method of the risk factor.The screening results were also normal at that time. [

However, Tang Screening is used to check for dementia, and the accuracy rate is only 70%-80%, and the accuracy rate of amniocentesis is more than 99%!But the former is less harmful to pregnant women.The latter is called intrusive inspection.

There are 3 different methods of invasive examination.The method of taking a small sample of villi from the placenta is called villus sampling.The method of taking a small amount of amniotic fluid from the uterine cavity for testing is called amniocentesis.The method of taking some fetal blood from the umbilical cord for testing is called a cordocentesis.If you are not careful, it may cause the fetus to slip.

Therefore, ordinary pregnant women do the first two things, and if they have doubts, they have to do the latter methods.

The female doctor's technique is very light and nimble, that kind of hand speed is a kind of talent, and it is also one of the reasons why Di Shajie must use this female doctor.She is indeed a genius at this, but she prefers to work with her brain rather than her hands.She likes forensic science, which is why she abandoned obstetrics and gynecology.
