Cerebrospinal fluid testing in children is a test in which a lumbar puncture is performed in the quiet state of the child and a specimen is taken for the diagnosis and identification of various inflammatory brain conditions. Normally, the normal value of cerebrospinal fluid pressure in children is 0.39-0.98 kPa. If the cerebrospinal fluid pressure in children changes and appears to be abnormal, such as elevated or decreased, it indicates the presence of disease in the body, and it is recommended to find the cause and treat the cause as soon as possible. When the cerebrospinal fluid pressure in children is higher than the upper limit of normal, patients often experience headaches, vomiting and other symptoms of increased intracranial pressure. There are many causes of this condition, including intracranial infections such as encephalitis and meningitis, intracranial occupying lesions such as brain tumors and cerebral hemorrhage, and extracranial lesions such as hypertension, lead poisoning and uremia, all of which can lead to different degrees of increased cerebrospinal fluid volume and increased pressure. When a decrease in cerebrospinal fluid pressure occurs in children, clinical manifestations may include dehydration and weakness. This is mainly considered to be caused by obstruction of cerebrospinal fluid circulation or excessive loss of cerebrospinal fluid due to craniofacial injury and other causes. However, abnormal cerebrospinal fluid pressure in children is not necessarily caused by the above diseases. Testing of cerebrospinal fluid pressure is an auxiliary diagnostic tool and should be analyzed by a doctor through other tests combined with clinical manifestations.
