Show Notes
Initial Approach to Diagnosing Migraines:
* Differentiating between primary headaches (migraine, tension-type, cluster) and secondary causes (e.g., subarachnoid hemorrhage).
* The importance of patient history and reevaluation after initial treatment.
* Recognizing the unique presentation of cluster headaches and their management implications.
Effective Acute Migraine Treatments:
* First-line treatments including anti-dopaminergic medications like metoclopramide (Reglan) and prochlorperazine (Compazine), and parenteral NSAIDs like ketorolac (Toradol).
* The limited role of triptans in the ED due to side effects and less efficacy compared to anti-dopaminergics.
* The use of nerve blocks (greater occipital nerve block and sphenopalatine ganglion block) as effective treatments without systemic side effects.
Treatments to Avoid or Use with Caution:
* Diphenhydramine (Benadryl): Studies show it does not prevent akathisia from anti-dopaminergics nor improve migraine outcomes.
* IV Fluids: Routine use is not supported unless the patient shows signs of dehydration.
* Magnesium: Conflicting evidence with some studies showing no benefit or even harm.
Managing Refractory Migraines:
* Second-line treatments including additional doses of metoclopramide combined with NSAIDs or dihydroergotamine (DHE).
* Considering opioids as a last resort when other treatments fail.
* The potential use of newer medications like lasmiditan and CGRP antagonists.
Preventing Recurrence of Migraines:
* Administering a single dose of dexamethasone (4 mg IV) to reduce the risk of headache recurrence after discharge.
* Prescribing NSAIDs or triptans upon discharge for outpatient management.
* Recognizing and addressing chronic migraine, and initiating preventive therapies like propranolol when appropriate.
Key Takeaways
* Differentiate Primary from Secondary Headaches and Reassess After Treatment:
* Use patient history and reevaluation post-treatment to distinguish migraines from more serious conditions, reducing unnecessary imaging and procedures.
* First-Line Treatments Are Effective:
* Anti-dopaminergic medications and NSAIDs are the mainstay of acute migraine treatment in the ED.
* Reserve opioids for cases unresponsive to multiple lines of treatment.
* Avoid Unnecessary Interventions:
* Diphenhydramine and routine IV fluids do not have proven benefits and can be excluded to streamline care.
* Utilize Nerve Blocks for Refractory Cases:
* Greater occipital nerve blocks and sphenopalatine ganglion blocks are ...
