What is it? Neurosonography is a complex name for a simple and harmless, but very important examination of a baby’s brain.
It is carried out on ultrasonic equipment, which appeared recently in Russia. Today, maternity hospitals, central children’s hospitals and many private diagnostic centers are equipped with such devices. The study takes place in 2 stages: first, the degree of maturity of the brain structures (convolutions, furrows, ventricles) is determined by one sensor, then a dopplerography is done with the help of another (vessels and blood flow are examined).
Signals emanating from the sensors enter the brain through the front fontanelle, located at the junction of the frontal and parietal bones; then they pass through its fabric. The image in 3D is displayed on the monitor, the specialist compares the parameters with the norms, identifies defects (hemorrhages, expansion of cavities, cysts) and gives a conclusion.
Ultrasound cannot pass through the bones of the skull, so after a year when the spring is closed, neurosonography is not done.
Why do you need? If there is evidence, the study will definitely be conducted in the maternity hospital in the first days or even the hours of the baby’s life. Neurosonography is prescribed in the following cases: if the pregnancy was accompanied by complications (severe toxemia, preeclampsia, chronic hypoxia, infections), if the baby was born earlier or later than expected, or suffered complications during childbirth (asphyxia, intrauterine infection).
The study will be conducted if the child weighs more or, on the contrary, less than the norm (2800 g), if his head has an unusual shape (asymmetrical, ovoid), as well as in the presence of neurological symptoms of central nervous system damage (reduced tone). In the absence of such indications, all children without exception are strongly recommended by doctors to undergo neurosonography for a month after discharge from the hospital.
Incredibly complex neurosonographic equipment is very easy to operate, and therefore the examination is almost always a problem.
The baby without a cap lies on a soft pillow, and sensors, smeared with a conductive gel, are alternately attached to its spring. It is important that the baby was at the same time calm.
Very well, when he sleeps and does not realize what is happening around. A sound sleep, according to ultrasound experts, contributes to a dense meal, so before the procedure, properly feed the crumbs.
The study itself will take 10–30 minutes, but it will also take time for the doctor to print the image and deliver the verdict. The only contraindication for monitoring is an increased body temperature, since on its background brain structures function in a different mode and look different.
