Abstract:

Study objective: We compare the efficacy and safety of sublingual buprenorphine versus intravenous morphine sulfate in emergency department adults with acute bone fracture. Methods: Enrolled patients received buprenorphine 0.4 mg sublingually or morphine 5 mg intravenously in this double-blind, double-dummy, randomized controlled trial. Patients graded their pain with a standard 11-point numeric rating scale before medication administration and 30 and 60 minutes after, and we recorded adverse reactions. Results: We analyzed 44 and 45 patients in the buprenorphine and morphine groups, respectively. Mean pain scores were similar at 30 minutes (5.0 versus 5.0; difference 0; 95% confidence interval -0.6 to 0.8) and at 60 minutes (2.2 versus 2.2; difference 0; 95% confidence interval -0.3 to 0.3). Adverse effects observed within 30 minutes were nausea (14% versus 12%), dizziness (14% versus 22%), and hypotension (4% versus 18%). Conclusion: For adults with acute fractures, buprenorphine 0.4 mg sublingually is as effective and safe as morphine 5 mg intravenously. [Ann Emerg Med. 2012;59:276-280.]
