Modified epidural needle applicator for nasal Sphenopalatine ganglion nerve block

摘要

Excruciating headache can follow the administration of spinal anesthesia. Typically, it worsens with sitting upright, improves with reclining and is accompanied by neck stiffness, tinnitus, photophobia or nausea. Transnasal sphenopalatine ganglion block has been traditionally used to treat chronic conditions such as migraine, cluster headache, trigeminal neuralgia, and atypical facial pain. Sphenopalatine ganglion block for the treatment of postdural puncture headache (PDPH) has been reported to be safe and effective (1-3).
