This randomized, double-blinded prospective study aims to determine the utility and efficacy of 3% hypertonic saline (HTS) to combat acute and long-term sequelae of TBI. We plan to enroll 74 participants, ages 8-17, who present to the pediatric Emergency Department with a mild TBI. The intervention group (n=37) will receive 5ml/kg of 3% hypertonic saline, and the control group (n=37) will receive 5ml/kg of 0.9% normal saline. There is a maximum volume of 500ml for both fluids. A standardized concussion inventory score will be used to assess the severity of symptoms pre-infusion, and post-infusion. Participants (or their parent/guardian) will be asked to complete two additional inventory scores one week and one month after the injury, of which they will be reimbursed for successful completion. Primary outcomes will be the efficacy of HTS in treating acute and chronic concussion symptomatology, and secondary outcomes will include unscheduled revisits to the ED.
