[Popular Science] A must-see for expectant mothers! Pregnancy ultrasound examination time and precautions

After pregnancy, expectant mothers are most concerned about: Is the fetus healthy? What does it look like? Is it developing normally? Ultrasound examination is the most common method for detecting malformation and fetal growth and development. It is usually carried out about 5 times during pregnancy. It is very important, but there are still some pregnant mothers who have misunderstandings about it. For example, they think that ultrasound has radiation, and four dimensions are better than two dimensions. The truth of these questions poke me here and read it, you will find that missing an ultrasound examination has such a great impact on the health of the fetus! Today, I will summarize the specific time and precautions of 5 ultrasound examinations during pregnancy for pregnant mothers and collect them quickly~ The moving picture is from SOOGIF

Pregnant 50 Days

Ultrasonic examination

About 50 days of pregnancy, mothers should undergo B-ultrasound examination. The fertilized egg implants in the womb or outside the womb. If there is no implantation in the normal uterine cavity, it is an ectopic pregnancy, in case of rupture, endangering the life of the mother and the fetus. If it is confirmed that it is in the womb and the fetal heartbeat can be seen again, then it can basically develop normally. The first child is an expectant mother who has a caesarean section, and it depends on whether it is implanted on the scar (scar pregnancy). A scarred pregnancy has a very dangerous prognosis, and some even lead to a hysterectomy.

Week 11-13+6

NT examination

It is recommended to do an NT examination from 11 weeks to 13+6 weeks of pregnancy to measure the thickness of the transparent layer of the baby's neck. NT thickening may be related to fetal chromosomal abnormalities, fetal cardiac structural abnormalities, congenital diaphragmatic hernia and other diseases, so this test is recommended for expectant mothers with high risk factors, such as advanced age, poor pregnancy history, or some comorbidities pregnant woman. Of course, not all babies with thickened NT have problems, so further screening is required. As an effective detection index, NT examination has been widely used in fetal screening during the first trimester.

22-26 weeks gestation

Three-dimensional ultrasonography

The best time to see the baby is at 22-26 weeks of pregnancy. The doctor will do a complete structural screening. The main purpose of this inspection is to check whether the fetus has major deformities. The intracranial structure, heart structure, gastric vesicle, kidneys, bladder, bowel, and long bones of the limbs are carefully examined. Many images of the baby are collected from head to toe, and carefully observe whether there are question. To do this examination well, you need the right time and place, the doctor has skills, the baby should cooperate, be able to move, do not sleep on his stomach, it is best to face the doctor. Sometimes the doctor thinks that the baby is not moving in the pregnant mother's belly, so the pregnant mother will go out for a walk and come back, waiting for the baby's whole body to turn around before looking at it, so this examination will take a long time, in order to check more accurate and complete.

28-32 weeks gestation

Growth measurement

During this period, the size of the fetus is mainly measured for growth, some malformations that may occur in the third trimester are screened, and the amount of amniotic fluid and the maturity of the placenta are also evaluated.

Prenatal ultrasound assessment

(term, before birth)

The purpose of this examination is to determine the fetal position, assess various fetal growth and development indicators and fetal bone weight. It should be emphasized that the detection rate of deformity screening at this time is already very high. Low, mainly to prepare for final production. The above are several inspections that expectant mothers should do during pregnancy. Of course, if the fetus has some other problems during pregnancy, follow up with the doctor's advice for dynamic observation.
