Regional Anesthetic Sphenopalatine Ganglion Block found Effective for Status Migraine

According to a recent study published in the "Headache" Journal, the Regional anesthetic suprazygomatic sphenopalatine ganglion (SPG) block shows promising results in providing immediate relief from Status Migraine (SM). In addition, the procedure is simple to perform and is associated with minimal risk.

SM is a condition in which the migraine attack lasts for more than 72 hours in patients with a previous migraine headache. Over the counter and abortive medications does not provide sufficient relief in this condition. SPG plays a vital role in developing both pain and the autonomic symptoms related to migraines. SPG block with transnasal lidocaine may provide moderate relief in migraine symptoms, but is not well tolerated. The investigators of the present study assumed that an SPG block using a suprazygomatic injection approach might present a safe and useful option to reduce pain and autonomic symptoms of SM.

The identification of patients for analysis was made as per the International Headache Society Criteria. A total of 68 women and 20 men who did not respond to two or more abortive drugs and had received a suprazygomatic SPG block were selected. The subjects were requested to rate their pain both before and 30 minutes after the suprazygomatic injection on the Likert scale (1 to 10).

A total of 252 administrations of suprazygomatic injections were received by 88 patients who failed to respond to other traditional medicines. A significant reduction of 67.2% (±26.6%) in pain severity with a median reduction of 5 points (IQR= −6 to −3) on the Likert scale (ranging from 1 to 10) was observed. Overall, patients experienced a considerable decrease in pain severity (P < .0001).
