Lumbar Puncture Needle Method

Lumbar puncture needle refers to the lumbar puncture to extract cerebrospinal fluid for etiological examination. It is mainly used for diagnosis and treatment of diseases. Clinically, it is mainly applied to the diagnosis of encephalitis and meningitis.
If subarachnoid hemorrhage is considered, cerebrospinal fluid is extracted by lumbar puncture for drainage treatment, mainly for the treatment of disease. The fourth and fifth intervertebral Spaces of the lumbar spine were the first choice for lumbar puncture, and the third and fourth intervertebral Spaces of the lumbar spine could also be selected. If the fourth and fifth intervertebral Spaces of the lumbar spine are selected, the tip of the needle should be slightly inclined to the Angle between the head and the spine of about 45 degrees.
If the third and fourth intervertebral Spaces of the lumbar spine are selected, the needle should be inserted vertically. In the process of cerebrospinal fluid retention, the flow rate must be slow to prevent the occurrence of cerebral hernia caused by increased intracranial pressure in patients. At the same time, after the completion of lumbar puncture, the patient must be instructed to lie flat for 4-6 hours with the pillow removed.
