Trick of the Trade: Sphenopalatine Ganglion Block for Treatment of Primary Headaches

It is thought that the autonomic nervous system is likely involved in migraines and other primary headache disorders given commonly associated symptoms such as nausea, lacrimation, emesis, and rhinorrhea. The sphenopalatine ganglion (SPG) is an extracranial parasympathetic ganglion with both sensory and autonomic fibers. It has therefore been hypothesized that blockade of the sphenopalatine ganglion may produce relief from primary headaches by modulating the autonomic fibers involved in headache disorders.1

While in our anecdotal experience with SPG blocks has been overall very positive, thus far there have been only a few small studies that have investigated it’s use in the Emergency Department. The currently available evidence has been mixed.

Tips for Interpreting the CSF Opening Pressure

Lumbar Puncture positioning. Creative Commons License - Blausen staffIn Emergency Medicine, we are like Goldilocks when it comes to many things: We don’t like a patient’s PaO2 to be too high or too low. We don’t like the bed too high or too low when we intubate. We get concerned when we see a potassium that is too high or too low. The Goldilocks principle is also true of opening pressures on a lumbar puncture (LP). This post will discuss what the opening pressure means, and a differential diagnosis for when it is too high or too low and even when it is in the normal range.

Lumbar Puncture on an Anticoagulated Patient in the Emergency Department: Is it safe?

lumbar punctureThe lumbar puncture (LP) procedure is commonly performed in the Emergency Department (ED). While minor complications of LP such as post-procedure headache or back pain occur somewhat regularly, significant complications such as post-procedural spinal hematomas, are rare.1 Despite their low incidence, these spinal hematomas are associated with a significant amount of morbidity for the patient and increased medicolegal risk for the provider.

Managing migraine headaches in complicated patients

migraineCase vignette: A 42-year-old female presents at 10 pm with a throbbing right frontal headache associated with nausea, vomiting, photophobia, and phonophobia. The headache is severe, rated as “10” on a 0 to 10 triage pain scale. The headache began gradually while the patient was at work at 2 pm. Since 2 pm, she has taken 2 tablets of naproxen 500 mg and 2 tablets of sumatriptan 100 mg without relief.

The patient has a diagnosis of migraine without aura. She reports 12 attacks per month. The headache is similar to her previous migraine headaches. She is forced to present to an Emergency Department (ED) on average 2 times per month for management of migraine refractory to oral therapy. She reports a history of dystonic reactions and akathisia after receiving IV dopamine antagonists during a previous ED visit. The physical exam is non-contributory including a normal neurological exam, normal visual fields and fundoscopic exam, and no signs of a head or face infection. When you are done evaluating her, the patient reports that she usually gets relief with 3 doses of hydromorphone 2 mg + diphenhydramine 50 mg IM, and asks that you administer her usual treatment. What do you do?

PEM Pearls: Migraine Treatment for Pediatric EM Patients

Her mother tells you that the around-the-clock ibuprofen has barely touched his 2-day headache.

After determining that your patient has no neurologic deficits and that this is most likely a primary headache, what can you do to break his symptoms?
