Contraindications To Lumbar Puncture

A lumbar puncture is a procedure that involving drawing out cerebrospinal fluid, fondly known as CSF. For example, it can be used to check CSF for immune cells and glucose levels in suspected meningitis.

Lumbar puncture is considered an invasive procedure. But even with that aside, it’s not appropriate for everyone. That is, it does not suit all patients.

Contraindications to lumbar puncture are:

  • Skin infection at the lumbar puncture site
  • Uncorrected coagulopathy
  • Increased intracranial pressure
  • Trauma to the spinal cord
