Summary

This study evaluates sphenopalatine ganglion block (SPGB) for the treatment of postdural puncture headache (PDPH) in the emergency department (ED). Half of the patients will receive a true nerve block with lidocaine and bupivacaine. The other half will receive a placebo nerve block.

Conditions

  • Postdural Puncture Headache

Interventions

PROCEDURE

Sphenopalatine Ganglion Block

Subjects will be asked to blow out each nostril. They will then be laid supine with a small shoulder roll and intranasal phenylephrine 0.25% (RhinallⓇ) will be sprayed once into each nostril to preemptively minimize bleeding. SPGB will be performed by inserting long cotton tipped applicators saturated in 2% viscous lidocaine into nostril until properly seated in the posterior nasopharynx. These will be left in place for 10 minutes and then 1mL of 0.5% bupivacaine will be administered down the plastic hollow shaft of each applicator via an 18g angiocatheter. The applicators will remain in place for 10 more minutes and then be removed.

PROCEDURE

Placebo

Subjects will be asked to blow out each nostril. They will then be laid supine with a small shoulder roll and intranasal phenylephrine 0.25% (RhinallⓇ) will be sprayed once into each nostril to preemptively minimize bleeding. SPGB will be performed by inserting long cotton tipped applicators saturated in carboxymethylcellulose based lubricant (i.e. K-Y Jelly®) into nostril until properly seated in the posterior nasopharynx. These will be left in place for 10 minutes and then 1 mililiter of normal saline will be administered down the plastic hollow shaft of each applicator via an 18g angiocatheter. The applicators will remain in place for 10 more minutes and then be removed.
