A Randomized, Sham-controlled Trial of Greater Occipital Nerve Block as Second Line Therapy for ED Patients With Acute Migraine
Abstract
This is a randomized, sham-controlled study of greater occipital nerve block (GONB) using bupivacaine 0.5% for emergency department patients with acute migraine. Patients are only enrolled if they fail first line therapy with metoclopramide.
Conditions: Migraine.
Primary outcome: Number of Participants Who Achieve Freedom From Headache.
Enrollment: 28 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 28 participants or records.
