Effectiveness of Sphenopalatine Ganglion Block for Post-Dural Puncture Headache

Effectiveness of Sphenopalatine Ganglion Block for Post-Dural Puncture Headache; A Pilot Study

The objective of the study is to determine the effectiveness of Spheno-Palatine (SP) ganglion block to alleviate the pain of post-dural puncture headache (PDPH).

The primary objectives of the study are to study the effectiveness of SP ganglion block in relieving post-dural puncture headache in terms of :

1. Number of subjects who get relief of pain
2. The onset time to pain relief after application of block
3. The duration of pain relief
4. The incidence of recurrence of post-dural puncture headache

Secondary objectives are to:

1. Monitor any complications due to SP ganglion block
2. Measure patient satisfaction
3. Monitor any residual effects at 1 months after the SP block

Inclusion Criteria:

1. Complains of symptoms suggestive of post-dural puncture headache
2. Has a history of dural puncture (lumbar puncture or accidental dural puncture during epidural placement) within the previous 7 days
3. Fluent in written and spoken English

Exclusion Criteria:

1. Those with a known history of hypersensitivity to local anesthetics of the amide type or to other components of GLYDO
2. Those with any congenital or acquired, anatomical deformity of the nostril, which preclude performing the block
3. Those who refuse to consent to participate in the study
4. Patients who have had a failed epidural blood patch
5. Cognitive Impairment
6. Prisoner
