HCG, progesterone, gestational sac, yolk sac, germ, fetal heart, self -sizes of pregnancy week, etc.
In the second trimester of pregnancy:
NT values, amniotic fluid, Tang sieve, large row of tertiary, placenta position, sugar resistance, several fetal development indicators: double top diameter, head circumference, abdominal circumference, and femoral length SD, etc.
(Some of the contents in the text are not written in the comments).
① It is a human chorionic gonadotropin, and it is a indicator of pregnancy.
② The HCG value during pregnancy will increase. If the embryo develops well, HCG will double the next day.
For example, today’s check value is 400, and it will turn to 800 the next day. If it is not very good, you must consider the possibility of ectopic pregnancy.
③ At the same time, it is also a indicator of monitoring of ectopic pregnancy
① progesterone is a hormone secreted by the luteal, which can only play a role on the basis of estrogen.
② During pregnancy, quantitative progesterone hormone levels are necessary conditions for maintaining pregnancy.
③ The value of progesterone in the early stages of pregnancy can be greater than 20ng/hm, which is ideal. If it is lower than 20, whether to protect the doctor to see what the doctor says.
① The gestational sac refers to a layer of membrane wrapped outside the germ, which has a protective effect on the germ.
② General blood HCG value is about 3000miu/ml, Yin Chao should be able to see the pregnancy sac.
It is a sign of early pregnancy capsules. Generally, early pregnancy, the uterine color ultrasound examination is only seen in the uterine cavity, and the yolk sac or fetal buds appear in the gestational sac to belong to the normal intrauterine pregnancy.
① Gel refers to the embryo before 8 weeks of pregnancy.
② HCG value can see the heart of the germ more than 50,000 or more.
① The frequency of heartbeat of the fetus at the fetus is an important criterion for reflecting the health of the fetus.
② General fetal heart beat 120-160 times per minute.
① The normal menstruation algorithm
The gestational week is calculated from the first day of the last menstruation.
② Some irregular menstruation, fertilized eggs Outlier in bed are late
Seeing the germ values (CM) on the B -ultrasound in the early pregnancy (CM) plus 6.5 is probably the range of pregnancy weeks. After that, the result obtained by 7 is used by 7 to get the number of days of pregnancy.
① The normal pregnancy cycle is 280 days, that is, 40 weeks.
② Every 7 days is a pregnancy week, that is, 40 weeks.
③ The pregnancy week is the fetal age of the fetus. Live -born babies born within 37 weeks of pregnancy are called premature babies; newborns born within 37 to 42 weeks of pregnancy are normal newborn students;The increase in fetal mortality in the ex -pregnancy pregnancy, at this time, the maternal should go to a regular medical institution in time.
① The calculation algorithm is:
In the last period of the number of menstruation, 9 or 3 minus 3, and the day plus 7.
② The due date is not the real production date, it is about the approximate time. The birth of the birth within two weeks before the due date is a normal range.
① Pregnancy is generally established to establish a health care manual for pregnant women.
② Usually record the results of the pregnant woman’s examination during pregnancy, the results of the pregnancy period and the condition of the body, and so on.
③ If you want to build files after pregnancy, it is best to prepare to produce in which hospital, which hospital is built in which hospital, and after the archives are under construction, you must go to the hospital for check -up.
We are regulations that can only be used as a local hospital to build files
① Refers to hypertension during pregnancy.
② High pressure greater than or equal to 140 mm Hg and low voltage greater than equal to 90 mm Hg
12. NT (need to make an appointment in advance)
① The baby is the first time that the baby has excluded deformities.
② It is the maximum thickness of the tissue effusion behind the baby’s neck.
③ The measurement time is 11 weeks of pregnancy +13 weeks +6 days.
① After more than ten weeks, the embryo has obvious amniotic fluid. Since then, the fetus has lived in amniotic fluid, and amniotic fluid has the effect of protecting, buffering, and moisturizing the fetus.
② Pregnant mothers have two amniotic fluid values when they do B time:
The depth of the amniotic fluid index and amniotic fluid.
③ amniotic fluid index
Cross the cross through the abdomen, and the abdomen part of the four areas. The total amount of the depth of the amniotic fluid in each area is the amniotic fluid index) normal value is 8–18cm.The amniotic fluid index exceeds 25cm, indicating too much amniotic fluid; the amniotic fluid index is less than 5cm, indicating that there is too little amniotic fluid.
④ Maximum depth of amniotic fluid
It is the maximum depth of vertical amniotic fluid area, and the normal value is 3–7cm.The maximum depth of amniotic fluid exceeds 7cm, prompting too much amniotic fluid; the maximum depth of the amniotic fluid is less than 3cm, and it is reminded that the amniotic fluid is too small.The baby lives in amniotic fluid, and the amount of amniotic fluid is closely related to the baby.
Therefore, pregnant mothers should not only pay attention to the baby’s fetal movement, but also pay attention to the results of amniotic fluid examination.Doctors will give guidance based on the condition of amniotic fluid.
① It is to screen the Donald syndrome suffering and screen the baby whether the baby is Donald (low energy)
② Tang Si is best done in 15-20 weeks. If you miss it, you need to do amniotic fluid puncture directly.
③ Need to take blood on an empty stomach
① The best examination time of B super large row is 20-24 weeks,
② Dragon abnormalities are the development of the tissue and organs of the baby through color Doppler ultrasound. It mainly exclude major deformities such as congenital heart disease, cleft lip, polygon, spine, and brainless children.
③ There are two -dimensional (black and white photos), three -dimensional (color Doppler ultrasound), and four -dimensional (more detailed color ultrasound) form. Checking the data is the same, but the baby’s photos are different.
① The widest length between the tire baby’s head, left and right sides, is also called "head large horizontal diameter".
② Generally, after May pregnancy, the double diameter of the fetal baby is basically consistent with the pregnancy month, that is, about 7 cm in July in pregnancy, and about 8 cm in August of pregnancy, so on.In full moon, the double top diameter should reach 9.3 cm or more.
③ The double -top diameter is usually used to determine the development of the baby’s baby and whether it can be delivered.If the double -top diameter is large, expectant mothers are best to go to the hospital to do a B -ultrasound to check if there is water in the baby’s brain.If you do n’t have to be careful, your baby is large, which will increase the difficulty of delivery. Pay attention to nutritional balance. Multi -activity can improve this situation.
④ If the double -top diameter is small, you should also go to the hospital for examination. If there is no abnormality, don’t worry too much. Pay attention to strengthening nutrition, eat more high -protein foods, and regularly do regular physical examination.
① It is calculated based on the double -top and horizontal diameter.Refers to the distance from the fetus to the back of the back brain, which can be represented by HC.
② The main purpose of measuring the head circumference is to determine the baby’s development.It has a close relationship with the double -top diameter. The double -top diameter is long, and the head circumference is large; the double -top diameter is short, and the head circumference is small.The data of the head circumference is normal, indicating that the baby’s baby is developing well and easy to give birth.
Refers to the length of the fetus’s belly for a week, and can be represented by AC.
The length of the fetal thigh bone can be represented by FL.
The length of the upper arm bone on the fetus can be represented by HL.
The distance from the nasal root of the fetus to the pillow bone can be represented by OFD.
① The placenta is attached to the front wall, back wall, and side wall of the uterus.
② front placenta
Refers to the placenta attached to the lower section of the uterine after 28 weeks of pregnancy, and even the lower edge of the placenta reaches or covers the inner mouth of the cervix. The location is lower than the tire first exposure. The front placenta is more dangerous.The phenomenon.However, as long as the placenta position is not lower than the fetal first exposure, the placenta is located in the front of the uterus, the rear wall, and the side wall.Pregnant mothers usually have to carefully observe their physical condition, and feel uncomfortable to go to the hospital for examination in time.Usually pay more attention to rest, do not overwork, diet light, and sufficient sleep.
① The palace high refers to the length between the upper edge of the lower abdomen to the upper edge of the upper edge to the bottom of the uterine.
② It is closely related to the development of the fetus, and the palace height must be measured at each time during prenatal examination.By measuring the palace height, you can estimate the weight of the fetus.
③ The palace high should be increased by 1 cm per week.After entering the third trimester, when the head of the fetus enters the pelvis, the rising rate of the palace height will slow down.
④ If there is no change in the palace high for 2 consecutive weeks, you should pay attention to it and go to the hospital for examination.(Moms and prospective dad can also measure the palace high at home. Specific mothers urinate first, and then lie on the bed, bend their legs, and the prospective father uses a soft ruler to help measure.)
① Umbilical artery S/D refers to the ratio of systolic blood pressure and diastolic blood pressure of fetal umbilical artery.It is usually used to understand the blood supply of the mother’s placenta.
② During normal pregnancy, the measured value should gradually decrease with the increase of the gestational week, indicating that with the increase of the gestational week, the blood flow resistance of the placenta gradually decreases, and the blood flow increases, thereby ensuring normal blood supply to the fetus.
③ S/d is less than 3. during the near -month pregnancy.
S/d about 3.5-5.5 at 24 weeks of pregnancy, generally no more than 5.5,
24-30 weeks s/d = 2.5-5.0, generally not more than 5;
30-36 weeks S/D = 2.5-4, generally no more than 4;
36-40 weeks s/d = 1.7-3, generally no more than 3,
The high S/D value can affect the blood supply and oxygen supply of the fetus.
③ If S/D is too high, it can be improved by sucking oxygen by proper exercise (combined with its own situation).
Represented the maturity of the placenta, and the placenta grading is a judgment of the placenta maturity.
① The placenta grading generally starts from the B -ultrasound report in the third trimester, divided into 4 levels.At 28 weeks of pregnancy, most of the placenta grading is 0-I; by about 36 weeks of pregnancy, the placenta level may be I-II; by about 40 weeks of pregnancy, the placenta level may be II-III.Each level represents different maturity of the placenta.
Level 0: Placenta is immature; level I: placenta is basically mature;
Class Ⅱ: mature placenta; level III: placenta maturity and aging.
