Lumbar puncture is contraindicated in raised ICP. So how do we get to know whether ICP raised without inserting needle?
On CT or MRI we can see large dilated ventricle - suggest ICP is raised
but is it recommended to go for ct / mri before LP
that I doubt, may be we can do it in suspected patient
Indication for imaging before lp- FAILS - P
Focal neurological deficits
Altered mental status
Immunodeficiency
Low GCS
Seizures
Papilloedema
Widened Pulse pressure
Projectile Vomiting
Bradycardia
Irregular respiration
Papilledmea
Always do ophthalmoscopy before LP, to rule out papilledema
