What does nt mean? It is an important examination to check the thickness of transparent layer of fetal neck and screen Down syndrome and nt. Emma NT time is 1 1- 14 weeks. You can't do it if you miss it.
What does the S/D value of prenatal examination mean? With the progress of pregnancy, umbilical cord blood flow will increase steadily in diastolic period, and the ratio (S/D value) of the highest systolic blood flow velocity (S) to the lowest diastolic blood flow velocity (D) of fetal umbilical artery will decrease, thus reducing the resistance of fetal placental circulation and being beneficial to fetal development.
The research results for many years show that the S/D value of fetal umbilical artery is an ideal parameter for monitoring intrauterine conditions, and the method is simple and easy to calculate, which is more suitable for the fetus.
If D=0 or negative, umbilical artery resistance index (RI) can be used for analysis. The free segment of umbilical cord in amniotic fluid can also be measured by continuous Doppler or pulsed Doppler ultrasound under the condition of no fetal respiratory movement and stable frequency spectrum. Clinical analysis shows that the S/D value of fetal umbilical artery decreases with the increase of gestational age. In the second trimester, 3.0 is the police, such as S/D&; Ge3 0, the S/D value should be monitored after 32 weeks of pregnancy.
In the process of clinical application, before 30 weeks of pregnancy, a large number of documents were based on S/D&; Ge3.0 is the boundary,&; Ge3.0 is abnormal, suggesting that the umbilical blood flow resistance is increased, and < 3.0 is normal.
What does BPD mean on the B-ultrasound list of prenatal examination? It is the distance between the biparietal diameter of the fetus and the parietal bones on both sides.
What does the first prenatal examination nt0. 1 mean? NT examination is of great significance for improving the detection rate of abnormal fetus and guiding clinical treatment.
What does the Chinese Nt for prenatal examination mean? NT in NT examination is a translucent abbreviation, which refers to the transparent layer of fetal neck and the thickness of subcutaneous tissue effusion at the back of fetal neck. By examining the thickness of the zona pellucida in the fetal neck, we can diagnose chromosomal diseases in infants and find fetal abnormalities caused by various reasons, such as fetal spina bifida, fetal spina bulge, hydrocephalus, widening of lateral ventricle, widening of posterior cranial cistern and cardiac malformation. 10 week-13 week is the best time for examination, and it can't exceed 13+4 weeks, otherwise the transparent layer of fetal neck will become thick and unclear. Check up at the time recommended by the doctor. At this point, the fetus has not yet formed. It is best to do four-dimensional color Doppler ultrasound. I worked in Wenzhou Oriental Maternity Hospital, hoping to help you ~ ~
What does atl 18 ↓40 mean on the physical examination form? The average normal person's alt should be 0-40. 62 is high. It is necessary to check it again.
There are many reasons for the high alanine aminotransferase.
It may be caused by the outbreak of viral hepatitis. It depends on whether your friend is a virus carrier. I suggest you do a test for hepatitis B and hepatitis A virus infection. If your friend is in the stage of hepatitis, the possibility of being infected is not ruled out. I suggest you also check hepatitis B and hepatitis B.
If viral hepatitis, fatty liver or inflammation of extrahepatic organs are excluded, alt can also be increased, such as cholecystitis. This needs to be confirmed by other tests, but it leads to an increase in transaminase, which is not contagious. Just take some drugs to repair the liver at the same time.
In addition, before physical examination, strenuous exercise, or excessive fatigue, or eating sexual food, or some side effects of drugs, will cause an increase. Just have a good rest.
Abnormal liver function caused by elevated transaminase will not affect the interview, but if the physical examination will have an impact, I suggest you find out what the reason is as soon as possible.
Why does my 34-year-old birth certificate say that the fetus presents H first? What does this mean? It means that you are breech and the baby is below.
Fetal presentation is a very common medical term in obstetrics and gynecology. Fetal presentation is the first part to point out the fetus at birth. The most common part of fetal presentation is the head. Your checklist shows that the fetal heart is located at the lower right of the umbilical cord.
What does the reference value on the urine routine report mean? The values of those examination items of healthy people are all within that range (reference value).
