What to do if the baby does not cooperate with the four-dimensional

Many pregnant mothers actually need to undergo prenatal checkups when they are pregnant. Prenatal check-ups not only allow mothers to see the development of the fetus, but also allow them to know the fetus's developmental status in a timely manner. Many people think that prenatal check-ups are very simple, but in many cases, it is difficult if the baby does not cooperate. What should I do if my baby refuses to cooperate with the four-dimensional measurement during the prenatal checkup?

What should I do if my baby does not cooperate with 4D color Doppler ultrasound?

Generally, if you walk around for half an hour and then do it, it should be able to turn around. The reason for the lack of cooperation is that we can't see the baby's face to see if there is a cleft lip. The chance of this is very small. As long as other parts are normal, there should be no problem.

Four-dimensional color ultrasound is a type of ultrasound examination. In addition to the functions of general color ultrasound, it can also perform three-dimensional imaging of the fetal head and face, and can clearly show the conditions of the eyes, nose, mouth, jaw, etc. It can assist doctors in directly diagnosing congenital malformations of the fetus, including surface malformations, visceral malformations, and head and facial malformations, and can determine the exact position of the fetus in the uterus. In addition, four-dimensional color ultrasound adds time dimension parameters based on these functions, which can observe dynamic activity images of the fetus in real time.

Generally speaking, four-dimensional color ultrasound can reveal major malformations of the fetus, such as congenital heart disease, cleft lip and palate, hydrops fetus, polydactyly and external ear malformations. However, four-dimensional color ultrasound is not omnipotent. For example, it cannot detect deafness and cataracts in newborns.

Pregnant women should understand the importance of four-dimensional color ultrasound screening and undergo four-dimensional color ultrasound examination at the time prescribed by the doctor.

Generally speaking, the best time to take a four-dimensional color ultrasound is between 24 and 28 weeks of pregnancy, because the fetus's brain is developing rapidly around 24 weeks. The fetal structure has been formed at this time, the fetus is of moderate size and amniotic fluid, there is more room for movement in the uterus, the fetal bone echo is less affected, and the image is clearer.

Four-dimensional ultrasound has real-time dynamic effects based on three-dimensional ultrasound. Expectant fathers and mothers can witness the baby's movement, breathing, swallowing, yawning, sticking out the tongue and other physiological activities in the mother's belly through the screen, which is very intuitive.

Choosing the best time to do the four-dimensional color ultrasound examination, in addition to leaving precious imaging records for the child, its more important role is to rule out fetal abnormalities. Four-dimensional ultrasound examination can be performed at any stage of pregnancy, but the best time is 20-26 weeks of pregnancy. At this time, the main organs of the fetus have developed, the amount of amniotic fluid is appropriate, and the fetus has entered the abdominal cavity, which is convenient for screening of fetal malformations.

What does 4D color Doppler ultrasound check?

Four-dimensional color ultrasound is used to observe the growth and development of the fetus in utero, screen for fetal malformations, and provide an accurate scientific basis for the early diagnosis of congenital surface malformations and congenital heart diseases of the fetus.

1. Fetal facial deformities: such as cleft lip and palate; nervous system: anencephaly, hydrocephalus, microcephaly, spina bifida and meningocele.

2. Digestive system: umbilical enterocele, visceral exstrophy, intestinal atresia and megacolon, etc.

3. Urinary system: hydronephrosis, polycystic kidney disease, megacystis, and urethral obstruction.

4. Other deformities: short limbs, conjoined twins, cleft lip, four-chamber heart, polyhydramnios, oligohydramnios, etc.

Four-dimensional color ultrasound surface imaging is used in obstetric examinations. It can not only observe the growth process of the fetus, but also intuitively see the fetus's activities in the mother's body, such as breathing, movement, including large movements of the whole body, movements of limbs, and even the fetus's tiny swallowing movements. Doctors can also use four-dimensional color ultrasound to observe whether the fetus has good tension.
