Introduction: This study was designed to assess the possible superiority of intravenous lidocaine to morphine for pain management. Methods: This was a randomized double blind controlled superiority trial, carried on in the emergency department (ED). Traumatic patients older than 18-year-old with the complaint of acute pain greater than 4 on a numeric rating scale (NRS) from 0 to 10 on their extremities were eligible. One group received IV lidocaine (1.5 mg/kg), and the other received IV morphine (0.1 mg/kg). Pain scores and adverse effects were assessed at 15, 30, 45 and 60 minutes and patients� satisfaction was evaluated two hours later. A minimum pain score reduction of 1.3 from baseline was considered clinically significant. Results: Fifty patients with the mean age of 31.28 ± 8.7 were enrolled (78 male). The demographic characteristics and pain scores of the two groups was similar. The on-arrival mean pain scores in two groups were, lidocaine: 7.9 ± 1.4 and morphine: 8.0 ± 1.4 (p = 0.57) and after 1 hour were, lidocaine: 2.28 ± 1.2 and morphine: 3.2 ± 1.7. Although the pain score decreased significantly in both group (p = 0.027), there were not any clinically and statistically significant difference between the two groups (p = 0.77). Patients� satisfaction with pain management in both groups were almost similar (p = 0.49). Conclusion: The reduction in pain score using IV lidocaine is not superior to IV morphine in adult ED patients with traumatic limb pain. © 2017 Elsevier Inc.
