Lumbar Punctures

Post Dural Puncture Headache



    • Clinical Features

    • May occur hours or days after LP
    • Headache
    • Nausea / vomiting
    • Dizziness
    • Mechanism

    • Unknown, but thought to relate to reduced CSF pressure / compensatory venodilatation.
    • Prevention

    • Use an atraumatic needle rather than a cutting (bevelled) needle
    • Use the smallest bore needle possible
    • Reinsert the stylet prior to removing the needle
  • Several studies (Straus et al, Spriggs et al) suggest that bed rest post LP has no preventative effect on post-LP headache.
