Brief Summary: Abstract Background: Ketamine has been introduced as one of the most common drugs, administered to sedate children for different painful procedures in the emergency department (ED) but administration in higher dosage causes some severe complications. Thus, the aim of this study was to evaluate the effect of low-dose intravenous ketamine bolus versus conventional injection for reduction of upper and lower extremity fractures in children.Conditions
Materials and Methods: In this randomized clinical trial, 198 participants with upper and lower extremity fractures were enrolled. The participants were divided randomly into two groups. In the intervention group, ketamine 1% was administered rapidly at a dose of 0.5 mg / kg (within 5 seconds), and in the control group, ketamine 1.5 mg / kg was slowly injected for 30 to 60 seconds. Then outcomes such as sedation depth and complications were measured for every two minutes and satisfaction of participants and physicians were recorded.
Results: Results showed that the successful sedation rate in the low dose ketamine group was significantly lower, as compared to the control group (7% vs 100%) (p<0.001). Moreover, In terms of duration of drug effect and of recovery, the low dose ketamine group were significantly lower compared with the group receiving higher dosage of ketamine (p<0.05). Furthermore, the sedation depth based on Wisconsin Sedation Scale was significantly higher, in the low dose ketamine group compared to the other group. By evaluating different complications, we found that the rate of neurological (20.4 % vs 5%) and physiological (10.2% vs 2%) complications in the control group was significantly higher compared to the group receiving low-dose ketamine (p<0.05).
