In order to improve the eugenics rate, pregnant mothers will regularly do relevant obstetric examinations during pregnancy, so what are the important obstetric examination items in the first and second trimesters of pregnancy?
First check-up: 6-8 weeks' gestation
The first gynecological routine examination and ultrasound examination during pregnancy are mainly to understand the genital tract and reproductive organs, determine the location of the fetal sac, determine the number of embryos, and exclude ectopic pregnancy.
Second obstetric check-up: 12 weeks of pregnancy is NT, fasting is recommended
The main items of the 12-week pregnancy examination are the establishment of a pregnancy health manual, the determination of the gestational age, and the estimation of the expected date of delivery. Evaluation of risk factors during pregnancy, blood pressure, body weight, blood routine, urine routine, blood group (ABO and Rh), fasting blood glucose, liver and kidney function, hepatitis B virus surface antigen, treponemal toxin, HIV screening, electrocardiogram, Doppler hearing fetal heart rate. NT screening can be done between 11-13 weeks and 6 days of pregnancy, mainly to check whether the thickness of the transparent layer of the fetal neck is normal, the normal range is within 3mm, but generally more than 2.5mm, the doctor will prompt the NT high value, and further chromosomal examination is needed to confirm the diagnosis.
Third check-up: 16-18 weeks of pregnancy is recommended on an empty stomach
In 16-18 weeks need to do the color ultrasound check again at the gestational week, in a certain number of weeks can do Tang sieve or non-invasive DNA test, generally recommended age over 35 years old to do non-invasive DNA, so the results are more accurate, because the false positive rate of Tang sieve is very high. There are many pregnant mothers who are doing Tang screening, the result is high risk, when doing noninvasive is low risk, in this process will be very worried, so older women can directly choose non-invasive DNA test.
Fourth check-up: 20 weeks' gestation
Obstetric examination items: blood pressure, weight, height of the uterine floor, abdominal circumference, Doppler hearing fetal heart, ultrasound fetal malformation screening (18-24 weeks), blood routine, urine routine.
Warm tips: Ultrasonography is mainly to see if there are major problems in the appearance and development of the fetus.
Fifth check-up: 24 weeks pregnant fasting is recommended
22-24 weeks is the most important number of weeks to screen fetal malformations, but also the best period for screening the fetal heart, pregnant mothers must not miss this large row of teratology examination, four-dimensional color ultrasound can see whether the fetus has malformations, such as: cleft lip and palate, nasal bone loss, short limbs, heart valve defects, etc. can be clearly displayed, but there are also some factors that affect the results of the examination.
Obstetric examination items: blood pressure, weight, height of the uterine floor, abdominal circumference, Doppler hearing fetal heart rate, gestational diabetes screening (oral glucose tolerance test), blood routine, urine routine.
Iberian Baomei warm tips: the obstetric examination in the first trimester is very important, not only can prevent related genetic diseases, improve eugenics rate, but also understand the physical condition of pregnant mothers and the development of the fetus, and can also be timely conditioned and treated when encountering problems.
