Question
Why do newborns need a lumbar puncture to draw cerebrospinal fluid? Why is this test done?
Answer
Lumbar puncture, commonly referred to as a spinal tap, is a medical procedure that involves inserting a needle into the lumbar area to withdraw a small amount of cerebrospinal fluid. This test is primarily used to assist in diagnosing certain neurological disorders, such as meningitis, encephalitis, and sepsis. The spinal tap provides doctors with information about the nature and composition of the cerebrospinal fluid, which helps determine the cause and severity of the condition. In newborns, lumbar puncture may be used to check for specific diseases like neonatal meningitis or blood infections. Although this procedure carries some risks such as brain herniation, nerve damage, bleeding, or infection, these complications can usually be avoided under the strict operation and management of professional healthcare providers. If you have any concerns or questions about your newborn’s health, it is recommended that you consult with a professional doctor.
