What exactly is a lumbar puncture? Is there any danger?

Lumbar puncture does sound scary and often reminds parents of "pain" and "sequelae". When a doctor says a baby needs a lumbar puncture to test cerebrospinal fluid, many parents get nervous and feel like their sky is falling. Lumbar puncture, in which a needle is inserted into the subarachnoid space through a gap in the lumbar spine, is used to extract cerebrospinal fluid for testing. Some diseases also require injections of drugs. When the baby has a fever, showing extreme irritability, head (the baby will not use language, head is often caused by a headache) or poor mental state, or even lethargy, coma, accompanied by projectile vomiting, repeated convulsions, or consciousness is still not clear after convulsions, are signs of central nervous system infection. The doctor should carry out the relevant physical examination, when the baby's neck stiffness, positive pathological reflex or suspicious, will be recommended to do lumbar puncture test cerebrospinal fluid. One is to determine whether the baby has central nervous system infection, and two is to further identify bacterial infection or viral infection. If the baby has intracranial hemorrhage or intracranial tumor, although there will be similar symptoms of central nervous system infection, but there is no need to do lumbar puncture, and intracranial hemorrhage or lumbar puncture contraindications, identification is actually very simple, do a head CT can see very clearly. Therefore, before doing lumbar puncture, head CT should be done first to exclude the above two diseases. View the original post
