Abstract
OBJECTIVES: Prevention and reduction of pain, anxiety, and fear during medical procedures is one of the most important factors that should be considered in pediatric emergencies. The aim of this study was to compare the efficacy of oral versus intranasal midazolam in sedation during radiologic imaging in the largest province of Iran, Kerman.
MATERIALS AND METHODS: Eighty children were enrolled in this single-blind clinical trial based on convenience sampling and were divided into two groups receiving 0.5 mg/kg midazolam in oral route administration and 0.2 mg/kg midazolam in intranasal route administration. Finally, 75 patients remained for evaluating medication acceptability, sedation level, onset time of sedation, additional sedative dose, adverse effects of sedation, and provider satisfaction.
RESULTS: Children in the intranasal group accepted medication more easily (89.8% vs. 36.9%; P≤ 0.001), while these children received a lower sedation dose, but the sedation level in both methods was similar (P = 0.72). Our findings showed that children in the intranasal sedation group had a faster onset of sedation compared to the oral group (17.94 ± 8.99 vs. 34.50 ± 11.45; P≤ 0.001). The frequency of midazolam side effects had no difference between the groups (29.7% vs. 15.8%; P = 0.15).
CONCLUSION: Intranasal midazolam with a lower sedation dose induces a faster onset and better acceptance. Intranasal midazolam can be used as an effective sedative method for pediatric patients, especially in emergency wards.
