Sphenopalatine Block or Epidural Bloodpatch for Post Dural Puncture Headache: Randomized Controlled Trial
Sphenopalatine Block or Epidural Bloodpatch for Post Dural Puncture Headache: Randomized Controlled Trial
Introduction: Recently sphenopalatine block emerged as an alternative to epidural blood patch
 for post dural puncture headache but the investigators do not know if it has significant
 efficacy when compared to epidural blood patch. Method: randomized trial where patients will
 randomly receive either sphenopalatine block or epidural blood patch. Pain relief to no pain
 or low intensity pain will be the main outcome
Introduction: Recently sphenopalatine block emerged as an alternative to epidural blood patch
 for post dural puncture headache but the investigators do not know if it has significant
 efficacy when compared to epidural blood patch. Method: randomized clinical trial where
 patients with moderate to severe post dural puncture pain will randomly receive either
 sphenopalatine block or epidural blood patch. Pain relief to no pain or low intensity pain
 will be the main outcome. Pain recurrence, survival without pain and side effects (tinitus,
 low back pain, new dural puncture, sore throat) will be secondary outcomes.
Inclusion Criteria:

 -  Moderate to severe post dural puncture headache

 Exclusion Criteria:

 -  Procedure failures: new dural puncture on epidural blood patch trial, unable to find
 epidural space, intolerance to insertion of nasal swabs.

 -  Follow up loss
