Why do newborns have lumbar puncture to test cerebrospinal fluid

Patient's question:

No

Doctor's answer:

A lumbar puncture is performed to better and more accurately diagnose diseases, such as meningitis or sepsis. A lumbar puncture is the abbreviation for "lumbar puncture," primarily involving the puncture to extract cerebrospinal fluid. 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.
