Post Dural Puncture Headache

 
 
 
Bookmark

Overview

  • 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.
