The objective of this study was to compare the efficacy of 3 doses of intranasal ketamine (INK) for sedation of children from 1 to 7 years old requiring laceration repair.Methods
This was a randomized, prospective, double-blind trial of children requiring sedation for laceration repair. Patients with simple lacerations were randomized by age to receive 3, 6, or 9 mg/kg INK. Adequacy and efficacy of sedation were measured with the Ramsay sedation score and the Observational Scale of Behavioral Distress–Revised. Serum ketamine and norketamine levels were drawn during the procedure. Sedation duration and adverse events were recorded.Results
Of the 12 patients enrolled, 3 patients achieved adequate sedation, all at the 9-mg/kg dose. The study was suspended at that time as per predetermined criteria.Conclusions
Nine milligrams of INK per kilogram produced a significantly higher proportion of successful sedations than the 3- and 6-mg/kg doses.
