Four dimensional color ultrasound baby has a big nose, what s going on?

Four-dimensional color ultrasound is to take a big picture of the baby's face to show you, which also leads to the baby's nose being slapped.

At 22 to 24 weeks of pregnancy, it is necessary to do four-dimensional color ultrasound to understand the current development of the fetus, and this examination has many items, and mothers can also take the opportunity to see the whole picture of the fetus. The baby's nose is large, as long as the proportion with other body structures is normal, there is generally no need to panic. In short, even if the fetus's nose is a little large at the time of the prenatal examination, it may just be a normal physiological manifestation, and when he gradually develops, the proportions of the whole body will become more and more harmonious.

Pregnant mothers should pay more attention to whether there is any abnormality in other data on the B-ultrasound list.

I think that although the four-dimensional view is relatively clear, it is still very different from the actual situation, it is not completely accurate, and the nose is only a general situation.

Four-dimensional color ultrasound is generally a dynamic image of the baby, sometimes in order to see the baby's facial development more clearly, it may be necessary to zoom in on the part, so the nose and mouth on the four-dimensional photo of the fetus are particularly large.

Female friends often have a certain understanding of the physical development of the fetus during pregnancy, but due to the different methods of examination items, and even the different locations of the examination, the results are often differentWhat's going on with a big nose for a four-dimensional color ultrasound baby

What is going on with the big nose of the baby doing four-dimensional color ultrasound The big nose of the baby is because some babies are thinner and look at the big nose, and so the baby is very small and not beautiful and ugly, and when it is four or five months old, the facial features will grow up, and it will become more and more beautiful.

24-28 weeks of pregnancy is the best time to take four-dimensional color ultrasound, because the fetus is about 24 weeks is the period of rapid development of the brain, the fetal structure has been formed during this period, the size of the fetus and the amniotic fluid are moderate, the activity space in the uterus is larger, the fetal bone echo impact is relatively small, and the image is relatively clear.

The best time to do 4D color ultrasound varies from person to person, and the results obtained from different needs of 4D color ultrasound will be different. Generally speaking, pregnancy can be divided into three stages: pre-pregnancy (January-March), second pregnancy (March-June), and third trimester (June-September).

In order to shoot the whole body of the fetus, you can choose to do four-dimensional color ultrasound in the first trimester at this time, when the fetus is still small, the whole body can be illuminated through the instrument, but it is not recommended to do four-dimensional color ultrasound in early pregnancy, so as not to have adverse effects on the fetus. In order to check the external defects of the fetus, you can choose to do four-dimensional color ultrasound in the second or third trimester of pregnancy, at this time, the fetal body has developed to a certain extent, and it is impossible to take a look at the whole body, but you can observe the shape of a certain part of the fetus.

How to look at the four-dimensional color ultrasound report 1. Look at the fetal head - see whether the outline of the single-fetal head of the four-dimensional color ultrasound report is complete, if it is defective or deformed, it is abnormal. No displacement of the midline and no hydrocephalus are normal. The measurement of the biparietal diameter of the fetal head is an indicator of gestational age and fetal maturity.

At 26 to 36 weeks of pregnancy, the double parietal diameter increased by an average of 0.22 cm per week. After 36 weeks of pregnancy, the rate of increase in the double parietal diameter gradually slowed down, increasing by only 0.1 centimeter per week. The biparietal diameter of a full-term fetus is between eight and ten centimeters.

The double parietal diameter can also ** the weight of the fetus. If the double parietal diameter reaches more than 8.5 centimeters, the fetus weighs more than 2,500 grams. Experts point out that if the diameter of the double top is between 9.1 and 10 centimeters, the newborn weighs between 3,276 and 3,925 grams, and the diameter of the double top is greater than 10 centimeters, and the newborn weighs more than 4 kilograms.

2. Look at the fetal heart - the fetal heart rate exists, strong is normal, weak There are two possibilities, one is that the fetus is sleeping, and the other is abnormal. The normal fetal heart rate is 120 to 160 beats per minute.

3. Look at the umbilical cord - under normal circumstances, the umbilical cord should float in the amniotic fluid, if you see the umbilical cord image in the fetal neck, it may be the umbilical cord around the neck.

4. Look at the length of the femur - refers to the length of the fetal thigh bone. Its normal value should be less than twenty to thirty mm different from the double parietal diameter value of the corresponding month of pregnancy.

Shooting angle issuesWhen the doctor does four-dimensional color ultrasound for the expectant mother, the most important thing is the simple and resistant deformity examination of the fetus, and will not deliberately choose the shooting angle, so the four-dimensional photo of the fetus is more like a "capture", sometimes the doctor chooses a little bit of the angle, which may cause the baby's nose and mouth to be large.

Caused by local magnificationFour-dimensional color ultrasound is generally a dynamic image of the baby, sometimes in order to see the baby's facial development more clearly, but also to zoom in on the part, which will also make the baby's four-dimensional photo on the nose and mouth appear particularly large.

VernixFour-dimensional color ultrasound is generally carried out at 6 months of pregnancy, at this time there will be a layer of vernix on the fetus, and the fetus will make the baby's ** look uneven, so when the doctor "captures", it will appear that the nose and mouth are big.

Health TipsIt does not mean that the nose and mouth are really so big after the baby is born, so pregnant mothers do not have to worry too much, as long as the test results are normal.

The main reason for the large nose of the baby in the four-dimensional ** is the angle of shooting, and the four-dimensional photo is more like a snapshot, and sometimes a little deviation will cause this phenomenon. The four-dimensional photo is only a vague influence of the baby, there is amniotic fluid in the womb, and there are limitations to the clarity of the photo, so the four-dimensional photo is used for deformity examination, and you can not choose the right angle to shoot. It won't affect the baby.

The first point, it is very likely that the child has inherited the genes of the parents, there must be a person with a big nose in the family, the second point, it is very likely to be caused by the baby's malformation and bleeding, pay attention to the third point, it is very likely that the imbalance of nutritional intake, the formation of the child's nose is very large, whether it has an impact depends on the final diagnosis of the doctor.

Babies are not born with a lack of fat, so it is normal for newborn babies** to be wrinkled.

The brain develops earlier than other organs in the body, so babies generally have larger heads than normal and return to normal proportions as they get older.

Case: Probably not!! It is said that it is all because of the amniotic fluid.
