Efficacy of outpatient infusion therapy in pediatric patients with postconcussive headaches.

Purpose: To determine the relative efficacy of intravenous therapy for postconcussive headaches in a pediatric population, as compared to oral therapy.

Methods: Pediatric patients treated for postconcussive headaches at an outpatient infusion clinic from 2016 to 2018 were selected for inclusion in the study. Of the 95 patients who were treated in clinic, 53 patients were selected for a retrospective chart review. Clinic visits before and after infusions were reviewed to determine changes in headache score (HA), symptom severity score (SSS), and self-reported symptom relief. An age-matched and SSS-matched group served as a control. The control group received only oral therapy for their headaches. The infusion consisted of parenteral ketorolac, compazine, diphenhydramine, and a normal saline bolus (20 mg/kg).

Results: Following infusion therapy, overall mean HA and SSS scores were both reduced (p < 0.0001). Oral therapy demonstrated a similar mean overall reduction in HA and SS scores (p < 0.0001). While both groups achieved a reduction in HA and SS scores, there was not a statistically significant difference in reduction of symptoms scores between the oral and infusion groups.

Conclusion: Infusion therapy is as effective at reducing HA and SSS as established oral therapies. Infusion therapy may have a shorter time to headache abortion than oral therapy based on pharmacokinetics. Further, some physicians are unwilling to allow an athlete to return to play while taking suppressive medication. Future studies may show that an infusion could allow a more rapid return to play and resolution of symptoms.
