This study compared the effect of intranasal ketamine versus intranasal fentanyl on pain management in isolated traumatic patients. The study found that the visual analog scale (VAS) scores of patients in the intranasal ketamine group were significantly lower than those in the control group and the intranasal fentanyl group at 5 and 10 minutes after intervention, with an onset of action within 10 minutes. Intranasal ketamine can be proposed as an appropriate analgesic medication for patients with isolated limb injuries, with a slightly higher incidence rate and severity of adverse effects compared to the intranasal fentanyl group.
Background: Given the inadequate control of pain in patients with the trauma that refer to the emergency departments, the rapid onset of action of intranasal administration in pain management, and the avoidance of administering opioid medications, the present study aimed at evaluating the effect of intranasal ketamine versus intranasal fentanyl on pain management in isolated traumatic patients. Materials and Methods: The current study was performed on 125 patients that were divided into the following three groups: control group (n = 41), 1 mg/kg intranasal ketamine group (n = 40), and 1 mu g/kg intranasal fentanyl group (n = 44). Then pain scores, heart rate, respiratory rate, blood pressure, and oxygen saturation were recorded at baseline, 5, 10, 15, 30, and 40 min after the intervention. Results: Visual analog scale (VAS) scores of patients in the intranasal ketamine group 5 and 10 min after the intervention were 61.50 & PLUSMN; 20.45 and 55.00 & PLUSMN; 21.96, respectively. The mentioned scores were significantly lower than the VAS scores of patients in the control group with the mean of 72.44 & PLUSMN; 22.11 and 66.59 & PLUSMN; 24.25 and the VAS scores of patients in the intranasal fentanyl group with the mean of 71.59 & PLUSMN; 22.09 and 65.00 & PLUSMN; 22.87 at 5 and 10 min after the intervention, respectively (P < 0.05). Conclusion: Given the onset of action in < 10 min, intranasal ketamine can be proposed as an appropriate analgesic medication in pain reduction of patients with isolated limb injuries. Moreover, the incidence rate and severity of adverse effects were insignificantly higher in the intranasal ketamine group as compared with the intranasal fentanyl group.
