Cerebrospinal fluid (CSF) is found in the ventricles and subarachnoid space and is usually removed by lumbar puncture for examination.
Before lumbar puncture, the purpose of the procedure should be explained to the family and consent should be obtained. Then, a professional doctor will perform the procedure by lying on the side with the hands on the knees, anesthetizing the patient and using a puncture needle to puncture the cerebrospinal fluid specimen, and then perform relevant laboratory tests such as cerebrospinal fluid routine and cerebrospinal fluid biochemical tests, which will help to complete the diagnosis of the disease and formulate the diagnostic and treatment plan.
Lumbar puncture is an invasive procedure and should only be performed after evaluation by a physician. The concept of aseptic operation must be observed during the operation, and when the cerebrospinal fluid specimen is retained, too much of it should not be retained at one time to avoid the formation of cerebral hernia, and the patient should lie down for 6 hours after the operation with the pillows removed.
It is recommended that patients choose regular hospitals for lumbar puncture and cerebrospinal fluid examination, and actively cooperate with doctors for follow-up diagnosis and treatment.
