Sphenopalatine Block or Epidural Bloodpatch for Post Dural Puncture Headache: Randomized Controlled Trial

Gabriel Guimaraes: 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:

• Diagnostic criteria for post dural puncture headache
• 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
