Safety of intravenous ketorolac therapy in children and cost savings with a unit dosing system.

摘要

OBJECTIVE: To determine the incidence of side effects with the short-term use of intravenously administered ketorolac in children and the overall cost savings with a unit dosing system. STUDY DESIGN: We prospectively examined the incidence of complications arising from the intravenous administration of ketorolac to 1747 children (14,810 doses) during a 3-year, 3-month period and assessed cost savings resulting from dividing 60 mg syringes into 7.5, 15, 30, and 60 mg unit doses. Complications were recorded prospectively into a computerized database. Estimated drug costs to the pharmacy were calculated on the basis of the total numbers of each drug fraction administered, with allowance for 1O% wastage as a result of drug expiration. RESULTS: Side effects occurring with ketorolac administration were rare. Four patients (0.2%) had hypersensitivity reactions to the drug, two of them possibly on the basis of latex allergy. Two patients (O.1%) had renal complications but were subsequently found to have underlying causes that could account for their renal symptoms. One patient (0.05%) had massive gastrointestinal bleeding in the postoperative period. With fractionation of 60 mg syringes, total drug cost to the pharmacy was Dollars 34,786, rather than the Dollars 86,639 that would have been spent had a single syringe been used for each dose. CONCLUSION: Ketorolac proved safe for short-term intravenous use in children more than 1 year of age when patients with known contraindications to the use of non-steroidal antiinflammatory drugs were excluded. A considerable reduction in drug costs can be achieved with fractionation of premixed syringes into unit doses.
