Can B-ultrasound hurt babies?
During the whole pregnancy, the routine prenatal examination will require three times of B-ultrasound examination, namely 18-30 weeks, 28-30 weeks and 37-40 weeks. The purpose of the first B-ultrasound is to know whether the fetus is singleton or multiple. The second B-ultrasound was an abnormal examination; The third B-ultrasound is an evaluation before delivery.
If B-ultrasound is done according to normal procedures and quantities, it will not have adverse effects on the fetus. But if you do B too early or too long every time, it is likely to endanger the health of the fetus. Therefore, when doing B-ultrasound, you should strictly follow the doctor's instructions, and don't do the examination at will.
Matters needing attention in B-ultrasound examination
1, don't do B-ultrasound casually.
Now many pregnant mothers want to know the sex of the fetus as soon as possible, or feel unwell, so they take the initiative to ask for B-ultrasound, which is wrong. Doing B-ultrasound at will seriously affects the health of pregnant women and fetuses.
2, B-ultrasound time should not be too long.
The time of each B-ultrasound should be controlled within 20 minutes, especially when pregnant women are sick and unwell, and the time of B-ultrasound should be shorter.
3, the operation process should be correct
Pregnant women must choose regular surgery in regular hospitals to do B-ultrasound. If the scanning probe stays in the same position for a long time, it may damage the brain development of the fetus.
4. Avoid flatulence food before B-ultrasound.
Pregnant women should be careful not to eat food that is easy to cause flatulence before doing B-ultrasound, otherwise it will affect the penetration ability of ultrasound and lead to the rejection of B-ultrasound images.
5. Know the situation first and then do B-ultrasound.
Pregnant women should know the relevant matters before doing B-ultrasound, such as whether it is necessary to hold their urine, otherwise it will affect the health of the fetus by delaying the examination or increasing the number of examinations.
6. Relax your mind
When doing B-ultrasound, pregnant women should try to relax and actively cooperate with doctors to avoid affecting the examination results. Therefore, it is safe for babies and pregnant women to have B-ultrasound examination at normal time and frequency. B-ultrasound can intuitively understand the development of the fetus, so that doctors can give correct advice and guidance.
Before doing B-ultrasound, pregnant mothers should know something about B-ultrasound and avoid eating food that is easy to cause flatulence. They need to relax under the guidance of a doctor and have a correct B-ultrasound examination. Never listen to the rumor that B-ultrasound affects the health of the fetus and refuse this examination, thus affecting the health monitoring of yourself and the fetus.
B-ultrasound is not everything.
Only some fetal developmental abnormalities can be detected, such as neural tube malformation, visceral eversion, congenital heart disease, polycystic kidney disease, limb malformation and so on. Moreover, due to the influence of fetal position, instrument or observer's experience, B-ultrasound examination is intermittent, not continuous, so some malformations may not be found accurately. For example, if the fetus puts his hand on his chest, his limbs overlap, or clenches his fist, some limb deformities may not be found at that time. Therefore, to ensure your baby's health, you should be fully prepared before pregnancy, stay away from harmful objects, exercise more, improve your body's disease resistance, and avoid bacterial and viral infections. These are prerequisites for the normal development of the fetus.
What can B-ultrasound detect?
B-ultrasound examination is a kind of ultrasonic examination, a non-surgical diagnostic examination, a new discipline and an indispensable diagnostic method in modern clinical medicine. In clinical application, B-ultrasound can clearly display various sectional images of various organs and surrounding organs. Because the image is full of three-dimensional sense and close to the real anatomical structure, the application of ultrasound can make a clear diagnosis at an early stage.
B-ultrasound can show the abnormal masses on the body surface, abdominal cavity and pelvic cavity, including their size, nature (solid, liquid and mixed), the source of the masses, the relationship with surrounding organs, and whether they are benign or malignant.
The location, size and nature of space-occupying lesions in some organs can be determined by B-ultrasound exploration, and their benign and malignant can be estimated. Clinically, it is often used to examine organs such as liver, spleen, gallbladder, pancreas, thyroid gland, breast, eyeball, uterus and ovary.
Through the understanding of the size, shape and internal structure changes of organs, we can evaluate whether organs have acute or chronic inflammation or degeneration. Such as acute and chronic hepatitis, liver cirrhosis, fatty liver and congestive splenomegaly.
Determine the location and size of bile duct stones, intrahepatic stones, pancreatic duct stones and urinary calculi.
For physiological or pathological hydrops, B-ultrasound can locate, quantify and characterize. For example, pleural effusion, ascites, pericardial effusion, tubal effusion, too much or too little amniotic fluid in pregnant uterus, etc.
Others, such as prostatic hypertrophy, environmental inspection, observation of fetal growth and development, presence or absence of congenital malformation, follicular monitoring of infertile women, etc. Can be determined by B-ultrasound.
