Why do newborns have a lumbar puncture to collect cerebrospinal fluid

Patient's question:

The child was just born and doesn't know what's wrong, there are always red spots on their body, and they are also spitting up milk. Why do newborns have a lumbar puncture to check cerebrospinal fluid

Doctor's answer:

A lumbar puncture is performed to better and more accurately diagnose diseases, such as encephalitis or sepsis. A lumbar puncture is the abbreviation for "lumbar puncture," primarily involving the extraction of cerebrospinal fluid through a puncture. Post-procedure complications may include herniation of the brain, nerve damage, bleeding, and infection. However, these risks can be largely avoided with strict operation and postoperative care. It's possible that the effects of cold medicine are still active, and there may still be eye discharge. You should encourage your child to drink plenty of plain water and monitor them for a week. If the eye discharge remains excessive, you can take them to the hospital for a check-up. Excessive eye discharge in children is a common phenomenon and there is no need to panic. The eyes are important organs, and I dare not recommend any eye drops casually. I also advise you not to use eye drops randomly.
