Effect of Regional Anesthetic Sphenopalatine Ganglion Block on Self‐Reported Pain in Status Migrainosus patients
Key Take-Away: 

The Sphenopalatine Ganglion (SPG), the cluster of nerve cells connected to the trigeminal nerve, the main nerve participating in headache pain disorders. Regional anaesthetic suprazygomatic SPG block is a simple and effective approach for quick relief of Status migrainosus (SM) with minimal risk.

ABSTRACT: 
Background: 

Status migrainosus (SM) is commonly known as a debilitating migraine attack lasting more than 72 hours in patients previously known to suffer from a migraine headache.

Methods: 

Through a retrospective records review, we identified patients with a well‐established diagnosis of a migraine, as per the International Headache Society criteria.

Patients selected for study inclusion were diagnosed with SM who had failed to respond to 2 or more abortive medications and received a suprazygomatic SPG block. Patients rated their pain on a 1–10 Likert scale, both before and 30 minutes after the injection.

Results: 

Eighty‐eight consecutive patients comprising 20 men and 68 women received a total of 252 suprazygomatic SPG block procedures in the outpatient headache clinic after traditional medications were not successful to abort their SM.

At 30 minutes after the injections, there was a 67.2% (±26.6%) reduction in pain severity with a median decrease of 5 points (IQR= −6 to −3) on the Likert scale (ranging from 1 to 10). All in all, the patients experienced a statistically significant reduction in pain severity (P < .0001).
 

 

Conclusion: 

The SPG is known to play an important part in the pathophysiology of facial pain and the trigeminal autonomic cephalalgias, although its exact role in the generation and maintenance of a migraine headache remains unclear. Regional anaesthetic suprazygomatic SPG block is potentially useful for immediate relief of SM. We believe the method is simple to perform and has minimal risk.
