Brief Summary

This study aims to determine the efficacy of the sphenopalatine ganglion block in the treatment of post-dural puncture headache in post-partum women at the Brigham and Women's Hospital by measuring VAS scores at times between 0 and 24 hours after the block. We hypothesize that there will be at least a 50% reduction in VAS scores at 4 hours after performing the sphenopalatine block as compared to baseline VAS scores.

Outcome Measures

Primary Outcomes (1)

  • Change in VAS scores for headache at 4 hours after the sphenopalatine ganglion block.

    measured VAS for headache

    4 h post-intervention

Secondary Outcomes (4)

  • Time to first request of medication for symptom control after the sphenopalatine ganglion block,

    24 h

  • Need for blood patch

    24 h

  • Presence of nausea, neck pain, visual changes post-intervention

    periodic questioning over 24h

  • Symptomatic relief of headache after the block

    24 h

Interventions

The patient will be placed supine, with head in sniffing position. Two long cotton-tipped applicators will be soaked in 4% lidocaine for 30 seconds. An anesthesia provider, after visually inspecting each nostril for any sign of deformity or blockage, will perform the block. A cotton tipped applicator will be inserted into one nostril at an angle perpendicular to the face, and will be advanced to the back of the nasopharynx until resistance is met. The procedure will be repeated in the other nostril. If the patient experiences any pain or discomfort, the physician will stop and redirect the applicator. The applicators will be left in place for 10 minutes, and then removed by the anesthesia provider.
