Sphenopalatine Ganglion Nerve Block for the Treatment of Migraine Headaches in the Pediatric Population
Abstract
BACKGROUND: Persistent headaches and migraines are common in pediatrics with various treatment options. The sphenopalatine ganglion (SPG) has been identified as communicating with the parasympathetic autonomic nervous system and pain receptors. In adults, SPG block is an established treatment but there is no published literature in pediatrics.
OBJECTIVES: The purpose of this study is to analyze the SPG block in pediatrics.
STUDY DESIGN: Retrospective, single-center study.
SETTING: This study was conducted at Phoenix Children's Hospital in Phoenix, Arizona.
METHODS: A comprehensive review of patient charts from 2015-2018 of all pediatric SPG blockades performed by interventional radiology were included in the analysis. Utilizing fluoroscopic guidance, a SphenoCath was inserted into each nostril and after confirming position, and 4% lidocaine injected. Pre- and postprocedural pain was assessed using the Visual Analog Scale (VAS). Immediate and acute complications were documented.
RESULTS: A total of 489 SPG blocks were performed in patients between ages 6 and 26 years who were diagnosed with migraine or status migrainosus. One hundred percent technical success was achieved with mean reduction of pain scores of 2.4, which was statistically significant (P < 0.0001). There were no immediate or acute complications.
LIMITATIONS: Results of this study were based on retrospective study. The use of VAS may be subjective, and the need of a prospective study may be necessary.…
How strong is the evidence?
Evidence Hub reads this as a cohort study, 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.
