Does the lumbar puncture affect the body

Complications of lumbar puncture include cerebral herniation, impaired cardiopulmonary function, regional or referred pain, headache, bleeding, infection, subarachnoid epidermal cysts, and CSF leakage. The most common complication was headache, which occurred in 36.5% of patients within 48 hours after lumbar puncture. The headache is caused by CSF leakage from the puncture site at a rate that exceeds the rate of CSF production. The increased incidence of headache was associated with the thickness of the needle used. The most serious complication is herniation of the brain, which can occur if the pressure difference between the skull and the spinal cavity is large. This pressure difference can increase during lumbar puncture, leading to brain stem herniation. By taking a detailed history and conducting a neurological examination, physicians can identify patients at high risk of cerebral herniation. If the physician remains concerned about performing a lumbar puncture, CT may be helpful, but increased intracranial pressure may not always be detected by imaging. However, not all patients need CT because it can delay diagnosis and treatment. Patients with hemorrhagic diathesis are highly susceptible to bleeding, which can lead to compression of the spinal cord. There is no absolute standard for the relationship between the degree of coagulopathy and the risk of bleeding, so the physician must make a judgment based on the clinical situation. Subarachnoid epidermal cyst is caused by skin emboli entering the subarachnoid space. It can be avoided by using needle with needle core. Clinically, a successful lumbar puncture has no long-term adverse effects on the body, and lumbar puncture is of great significance for the diagnosis of intracranial diseases.
