Why Does Some Person Have Headache Also Want To Do Lumbar Puncture Needle

A lumbar puncture is a needle inserted between the patient's third and fourth lumbar vertebrae. 2-3 ml of CSF was extracted from the subarachnoid space for laboratory examination. The subarachnoid space is the space between the brain and the spinal cord and the surrounding skull and spinal canal. The subarachnoid space of the brain communicates with the spinal cord. The full amount of liquid is cerebrospinal fluid, about 150 ml in total. It is continuously produced and absorbed every day, and the circulation is endless. Cerebrospinal fluid is produced by blood circulation through the villous lining of the cerebral interior (called the choroid) and the capillary endothelial cells in the brain. Therefore, the brain and spinal cord lesions. Especially early inflammation * Abnormalities can be detected by examination of cerebrospinal fluid. Many diseases of the brain and spinal cord (inflammation, tumors, etc.) can affect the changes in the properties of the cerebrospinal fluid. For example, the number of white blood cells in the cerebrospinal fluid in patients with various types of meningitis increases to a small degree, resulting in different changes in their appearance. Among them, the number of epidemic spinal meningitis cells was the largest. The appearance of cerebrospinal fluid was cloudy and changed like rice soup. The levels of sugar and chloride in the cerebrospinal fluid of tuberculous meningitis and fungal meningitis were significantly reduced. The individual pathogens can be found in the smear. It can be seen that lumbar puncture examination of cerebrospinal fluid is irreplaceable for the diagnosis of certain brain and spinal cord lesions by any modern advanced examination.
