Introduction: The quality of interventions in children is largely dependent on their control. Hence, this study compared the sedative effects of subcutaneous (SC) and intravenous (IV) Midazolam in pediatric sedation induction. Methods: This randomized clinical trial was conducted on children aged 1-6 years presenting to emergency departments of Shahid Sadoughi and Shahid Rahnemoon Hospitals, Yazd, Iran. Participants were randomly assigned to IV or SC midazolam using a jet injector and success rate, degree of sedation, and satisfaction of parents and physician were compared between groups. Results: 60 cases with the mean age of 3.15±1.43 (1-6) years were randomly assigned to the SC (30 cases) or IV (30 cases) groups (56.7% female). SC and IV groups were similar regarding the mean age (p = 0.165) and sex (p = 0.121). Depth of sedation (p=0.900), control of child (p=0.711), in-charge physician’s satisfaction (p=0.467), successful sedation and need for rescue dose (p=0.519) were not different between groups. IV midazolam group had a significantly shorter recovery time (about 10 minutes; p=0.040) and SC midazolam group had a significantly higher level of parent satisfaction (p=0.001). Conclusion: The findings indicate no significant difference in depth of sedation, control of child, in-charge physician’s satisfaction, successful sedation (reaching stage 1 of sedation or higher), and need for rescue dose of SC and IV midazolam. Parents’ satisfaction was significantly greater with SC administration and IV injection had shorter recovery time.
