NSH ( Neurosonography ) of a newborn is a hardware examination of the brain using an ultrasound device. It is used for early diagnosis of possible disorders in the work of the brain and the detection of pathological changes in the nervous system. These kinds of pathologies are the result of incorrect management of labor or occur in the unfavorable course of pregnancy.
Features of the nervous system of newborns
In the structure of the nervous system of a newborn, some features are noted. So, after birth, more than 25% of brain neurons are developed. At the same time, about 66% of the total number of active people begin to act in the half-year, and in 12 months - 90% of all brain cells actively function. Apparently, the brain most actively develops in infancy, up to about 3 months.
Also, the skull of a baby can not yet be called a whole, dense cranium, because of the presence between the bones of so-called fontanelles . Their dimensions are permanently fixed by measurement at NSG.
When is the NSG conducted?
Indications for the NSG can be very diverse. However, most often this study is appointed if you suspect:
- bleeding;
- tumors;
- developmental defects;
- hydrocephalus;
- inflammatory processes.
Also, in the event of any kind of situations that may be the cause of the development of pathology, ultrasound of NSH in newborns is used for diagnosis. The advantage of this method is that it can detect even small, minor lesions, which in the future can affect the work of the brain.
How is the NSG conducted?
The NSH of the brain of a newborn child is a fairly simple procedure, before which no training is required. In this case, the process of examination is no different from ultrasound, the only thing that the organ being examined is the head. NSH in newborns, as well as in children up to a year, is usually performed through open fontanelles. For older children, such a study is carried out exclusively through the temporal bone and is called TKDG.
Safety research
As a result of numerous studies, incontrovertible evidence has been obtained that the NSA is absolutely safe for the baby procedure. Before its appearance such small crumbs of a detail a computer tomography, which is carried out exclusively with general anesthesia.
The duration of such a study rarely exceeds 15 minutes, and the result is ready immediately. The study itself can be carried out more than once without harm to the child, which allows you to monitor the pathology in the dynamics.
Explanation of results
The deciphering of the NSH conducted by the newborn is done exclusively by the doctor. This takes into account all the specifics of the development of a particular child, as well as how the delivery was, whether there were any complications, etc. Therefore, the results may differ,
Thus, the NSG does not require preliminary preparation of the baby and, as a rule, is appointed by the doctor with expressed or hidden signs of neurologic pathology. Mom does not need to worry about the appointment of this survey - it is absolutely painless and does not have a negative impact on the baby.
