Dec 21, 2021
Lumbar puncture is the abbreviation of lumbar puncture. A basic examination performed by doctors to check the nervous system (including brain, meninges, and spinal cord) for disease. The method is to let the sick child lie on his side, hold the legs with both hands and bend his head toward the chest. The purpose is to make the spine bend the most and expose the intervertebral space. After disinfecting the skin of the waist, the doctor holds a long slender waist needle and pierces it through the skin into the spinal cord cavity. If the operation is smooth, when the needle reaches the predetermined position, pull out the needle core. Normal children will be white and transparent. The fluid (that is, cerebrospinal fluid) flows out slowly. The doctor should measure the pressure of the cerebrospinal fluid or calculate the number of drops per minute of the cerebrospinal fluid. Generally, 3 vials (approximately 2-3 ml per bottle) are kept, and routine cerebrospinal fluid examinations, biochemical index examinations and bacterial cultures are sent to them. The results of the cerebrospinal fluid examinations are used to determine the disease. . Generally, when the meninges and spinal cord membranes are inflamed.
The cerebrospinal fluid is often cloudy, and white blood cells can be found under a microscope, and the protein qualitative test can be increased; in the case of a virus infection, the cerebrospinal fluid is often ground-glass-like, and the protein and cell number are increased; if there is a bacterial infection, the cerebrospinal fluid tends to be like rice soup with cells The number can reach hundreds or thousands, even with pus, and the amount of protein is greatly increased. However, to determine what kind of bacteria is causing it, it is necessary to find bacteria through cerebrospinal fluid smears or through bacterial culture to confirm the diagnosis.
