What are the contraindications for lumbar puncture?
Absolute contraindications for performing a LP include infected skin over the puncture site, increased intracranial pressure (ICP) from any space-occupying lesion (mass, abscess), and trauma or mass to lumbar vertebrae.
Why is raised ICP a contraindication for lumbar puncture?
Patients with increased ICP from mass lesions often display decreased levels of consciousness, focal neurological signs or papilledema on physical exam. Any of these findings make lumbar puncture contraindicated until further evaluation can be undertaken.
Is tethered cord contraindicated to lumbar puncture?
