Interpretation of key items of early pregnancy and obstetric examination

In the first trimester Obstetric inspection item 1: Fetal neck translucency detection - fetal malformation screening (NT). Taken at 11-14 weeks of pregnancy, it refers to the accumulation of fluid in the subcutaneous tissue at the back of the fetus's neck. Studies over the past 10 years have found that increased NT thickness increases the likelihood of fetal abnormalities. When the measured value is less than 2.5mm, it is judged as normal.

Early pregnancy Item 2 of obstetric inspection: Rubella virus antibody. Rubella not only infects pregnant women, but can also cause vertical infection through the placenta and genitalia, leading to miscarriage, intrauterine growth disorders, and congenital malformations such as congenital cataracts, deafness, and heart disease. The detection of rubella virus-specific antibody IgM in the serum of pregnant women and the determination of rubella virus IgM antibody in the serum of pregnant women can help predict the pregnancy outcome and reduce the incidence of children with congenital rubella syndrome.

Early pregnancy Obstetric inspection item 3: Human immunodeficiency virus. AIDS, also known as acquired immunodeficiency syndrome, is a sexually transmitted disease caused by the human immunodeficiency virus (HIV). At present, the number of AIDS virus (HIV) carriers or AIDS (AIDS) patients in China is increasing, and the proportion of female infected persons is also increasing. Because 90% of HIV infections in infants and children are caused by mother-to-child transmission, HIV screening is very important.

Therefore, in order to prevent the occurrence of these diseases in time and ensure the healthy development of the baby, pregnant mothers must carry out early pregnancy inspections in time!
