Topical Ketoprofen Versus Placebo in Children Presenting With Ankle Sprain to the Emergency Department: A Randomized Controlled Study.

Abstract

Despite the favorable data concerning topical agents use in outpatient clinics, they are not commonly in emergency departments (EDs). The present study aimed to compare the effect of 2.5% topical ketoprofen (gel form) to placebo in children presenting with ankle sprain to the ED. Children between 7 and 18 years old presenting with ankle sprain composed the study population. Study patients were randomized into 2 study arms: 2.5% ketoprofen gel and placebo administered in a 5-cm area locally. Pain improvements at 15 and 30 minutes were measured by visual analog scale. Median pain reductions at 15 minutes for ketoprofen and placebo groups were 27.5 (16-39) and 5 (4-10), respectively. Median changes in pain intensity at 30 minutes for ketoprofen and placebo gel groups were 48 (43-52) and 9 (6-16), respectively. When compared 2 arms for the pain improvement at 15 and 30 minutes, the differences between 2 study drugs were 20 (13-28) and 35 (29-41), respectively. There were 7 (12.7%) rescue drug needs in the placebo group and 1 (1.7%) in the ketoprofen group (difference, 10.9%; 95% confidence interval, -6% to 7%; P = 0.83). There were no adverse effects in either group. Ketoprofen gel is superior to placebo in ceasing pain in children presenting with ankle sprain to the ED with a high safety profile.
