Intranasal Fentanyl Versus Morphine in Fracture Reduction in a Pediatric Trauma Center

Abstract

Purpose: Pain management in orthopaedic manipulation in the emergency department (ED) is crucial to decrease fracture reduction performed in the operating room. This study compared intranasal fentanyl (INF) with oral morphine in time of care and effectiveness on pain during the reduction of bone fractures in a pediatric trauma center. Methods: A before-and-after INF implementation study was conducted in a pediatric ED with a trauma center on children with a confirmed displaced closed fracture on radiographs with reduction and casting performed in the ED. The time of care, time for sufficient analgesia, effectiveness on pain, and tolerance were compared between both analgesics in 3 consecutive phases. Results: 77 children were included: 31 children received oral morphine and 46 INF. The time of care was shorter in the INF group (150 [111 to 193] minutes versus 215 [155 to 240], P = 0.01) as the time for sufficient analgesia (10 [9 to 13] minutes versus 80 [53 to 119], P < 0.001) with a higher pain reduction after a dose of INF (3 [0 to 4] versus 6 [3 to 7], P < 0.001) and less dose requirement (P = 0.002). Although pain scores were similar at arrival in both groups (P = 0.15), the pain was significantly lower before and during the procedure in the INF group and equivalent after the procedure (2 [0 to 4] versus 3 [0 to 5], P = 0.02, 3 [1 to 5] versus 7 [3 to 9], P < 0.001, and 1 [0 to 2] in both groups, P = 0.87, respectively). Keeping pain levels low during the procedure in the INF group allowed the extension to lower limb fracture reductions (P = 0.04). No serious adverse events were reported. Conclusion: INF reduces the time to obtain sufficient analgesia and time of care, with good effectiveness maintained during the procedure in fracture reduction, allowing the extension to lower limb fractures. Thus, this rapid and efficient analgesia facilitates orthopaedic care in the pediatric ED that would otherwise require to be reduced in the operating room under general anesthesia.
