New Guidelines Recommend Nerve Blocks for Emergency Migraine Treatment

Major Update in Migraine Treatment Protocols
A significant update to the American Headache Society's treatment guidelines has emerged, recommending that patients hospitalized for severe migraines receive targeted occipital nerve blocks instead of intravenous (IV) opioids. This change is based on a comprehensive review of 26 clinical trials assessing 20 injectable treatments for migraines, published in *Headache: The Journal of Head and Face Pain*.
Mechanism of Action
The occipital nerve blocks target the occipital nerves located at the base of the skull, which transmit pain signals to the brain. Dr. Serena Orr, an associate professor of neurology at the University of Calgary, explained that anesthetizing these nerves not only numbs the back of the head but also dampens pain signals from other areas of the head. The guidelines suggest that this nerve block should be administered alongside IV prochlorperazine, a medication effective in treating nausea and vomiting associated with migraines.
Shift Away from Opioids
The new guidelines explicitly advise against the use of IV opioids and acetaminophen for migraine treatment in emergency rooms. Despite previous recommendations against opioids, their usage has persisted, although it has decreased from 54% of cases between 2007-2010 to 28% from 2015-2018. Dr. Jennifer Robblee, a headache specialist at Barrow Neurological Institute in Phoenix, emphasized that this update represents a major shift in emergency department migraine care, advocating for more effective non-opioid treatments to improve patient outcomes and reduce opioid reliance.
Implications for Emergency Care
Migraine accounts for approximately 25% of the 3.5 million headache-related cases treated in U.S. emergency rooms annually. However, only 37% of patients leave the hospital without headache pain following treatment, highlighting a critical need for improved management strategies. The introduction of nerve blocks could potentially enhance treatment efficacy in emergency settings.
Challenges in Implementation
Despite the promising evidence supporting the new guidelines, Dr. Orr cautioned that it may take time for these practices to be adopted widely in emergency rooms. The successful implementation of nerve blocks will require trained personnel and adequate supplies, necessitating procedural training and support.
Conclusion
The updated guidelines signify a pivotal change in the approach to treating migraines in emergency settings, advocating for nerve blocks as a primary treatment method. As healthcare providers work to integrate these recommendations, the focus will remain on improving patient care while minimizing the use of opioids in migraine management.
