Stroke patients’ lumbar puncture
Normal cerebrospinal fluid is colorless, transparent, and watery, and the pressure measured during lateral decubitus positioning should be 70-80 mmHg. In patients with cerebral hemorrhage, cerebrospinal fluid pressure increases, often above 200 mmHg, and the cerebrospinal fluid is bloody. Microscopic examination reveals the presence of red blood cells, and the protein qualitative test is often weakly to moderately positive, with a mild to high increase in protein content. In patients with subarachnoid hemorrhage, pressure significantly increases, often above 300 mmHg, and the cerebrospinal fluid is also bloody.
The number of red blood cells in the microscope examination can reach 10-30 million/mm3, and the protein content mildly or moderately increases, with a mild to moderate positive protein qualitative test. In patients with cerebral thrombosis, the cerebrospinal fluid examination shows normal pressure, 90% of whom have colorless transparent fluid, and 10% have light yellow fluid. The microscopic examination is generally normal, occasionally with a small amount of red blood cells, and the protein qualitative test is often weakly positive.
Will sequelae be left after stroke patients’ lumbar puncture for CSF
Clinically, when lesions occur in brain tissue and meninges, such as cerebral hemorrhage, cerebral thrombosis, infection, tumor, trauma, and edema, they can cause changes in the nature, composition, and amount of cerebrospinal fluid. The changes of cerebrospinal fluid vary with the nature of the lesion. Therefore, the examination of cerebrospinal fluid is of great significance for the diagnosis and prognosis of central nervous system diseases.
Especially for bacterial meningitis, it has definite diagnostic significance. Whether the puncture site or the operation method, it is very safe to take cerebrospinal fluid through lumbar puncture. Taking out a small amount of cerebrospinal fluid for examination does no harm to the human body.
It is obviously unreasonable to argue that the examination of cerebrospinal fluid extraction will leave sequelae such as stupidity. The reason for this incorrect statement is that some diseases requiring cerebrospinal fluid examination, such as various meningitis, epidemic encephalitis B, poliomyelitis and other diseases, can cause some serious sequelae.
Even without cerebrospinal fluid examination, these sequelae will also occur.
Therefore, if there are stroke symptoms, suspected intracranial hemorrhage, coma, stroke, paralysis and other symptoms but the cause is unclear or the diagnosis of nervous system disease is unclear, we should listen to the opinions of the attending physician and make a clear diagnosis with the help of cerebrospinal fluid examination, especially in areas where modern diagnostic technology such as CT cannot be popularized, cerebrospinal fluid examination is a very important diagnostic means.
