Abstract
To compare the pain relief, sedation, and common side effect profiles of ketorolac tromethamine and meperidine for the management of acute pain in the emergency department (ED). A prospective, double-blind, randomized clinical trial was conducted over a 12-month period using consecutive adult patients presenting to a university teaching hospital ED (annual census: 32,000), who required IM analgesia for acute pain. Adult patients with acute pain of various etiologies were randomly assigned to receive a single fixed IM dose of ketorolac (60 mg) or meperidine (100 mg). Ninety-three patients were enrolled in the study; 46 were randomized to meperidine and 47 to ketorolac. Using a visual analog scale, there was no difference in pain relief between the ketorolac and meperidine groups even after adjusting for baseline pain level. Ketorolac caused significantly (p < 0.005) less sedation than did meperidine at one hour. Rescue analgesia was required for seven of the 46 (15.2%) patients receiving meperidine and five of the 47 (10.6%) patients receiving ketorolac (p = NS). Seventeen of 45 (38%) patients receiving meperidine experienced side effects compared with eight of the 47 (17%) patients receiving ketorolac (p = 0.0452). When used to treat patients who had acute pain states, 60 mg of IM ketorolac produced analgesia similar to that produced by 100 mg of IM meperidine; however, the ketorolac produced fewer subjective side effects and less sedation than did the meperidine.Keywords
