Evaluation of intravenous ketorolac administered by bolus or infusion for treatment of postoperative pain. A double-blind, placebo-controlled, multicenter study.

Background: Ketorolac is a nonsteroidal analgesic that may provide postoperative analgesia without opioid-related side effects. This double-blind, randomized, multicenter study evaluated the analgesic efficacy and safety of intravenous ketorolac in 207 patients during the first 24 h after major surgery.

Methods: Subjects were assigned to receive one of three analgesic regimens: a ketorolac infusion, ketorolac boluses, or placebo.

Comparison of ketorolac and meperidine in patients with postoperative pain--impact on health care utilization.

A double-blind, randomized study was conducted to compare the effects of intramuscular ketorolac tromethamine and meperidine hydrochloride, and subsequent oral pain medication, on health care utilization and postoperative recovery. Following abdominal hysterectomy or cholecystectomy, 210 patients (aged 18 to 70 years; 189 women, 21 men) were randomly assigned to therapy and evaluated for efficacy, safety, nursing care requirements, functional independence, recovery milestones, and quality of life. The patients received 30 mg of ketorolac intramuscularly every 3 to 6 hours as needed, followed by 10 mg of ketorolac every 4 to 6 hours, or 100 mg of meperidine intramuscularly every 3 to 6 hours as needed, followed by acetaminophen/codeine (600 mg/60 mg) orally every 4 to 6 hours.
