Clinical experience with ketorolac in children

OBJECTIVE: To describe the use of parenteral ketorolac in a large population of children, focusing on dosing patterns, efficacy, and safety. DESIGN: Observational, prospective study conducted over a four-month period. SETTING: A 122-bed children's medical center located within an academic medical center hospital. PARTICIPANTS: Children receiving ketorolac during their hospitalization. MAIN OUTCOME PARAMETERS: Indications for treatment, dose, dosing interval, use of a loading dose, length of therapy, efficacy (subjective response and use of concomitant therapy), and adverse effects (bleeding, gastrointestinal ulceration or vomiting, and renal dysfunction). RESULTS: Of 112 children evaluated, 110 received ketorolac for analgesia, and 2 were given ketorolac as an antipyretic. The children ranged in age from 6 months to 19 years. Doses of 0.5 mg/kg q6h were used for most children (range 0.17-1.0). The average length of therapy was 3.4 days (range 1-12). The most frequent reason for discontinuing ketorolac therapy was a change to oral therapy. Therapy was discontinued because of a lack of efficacy in only 2 children. Adverse reactions were unusual, with only 2 patients having bleeding potentially associated with ketorolac use. CONCLUSIONS: Ketorolac appears to be a safe and effective therapy for children when given in appropriate doses for a limited duration.
