Randomized Controlled Trial Comparative Study
Comparison of Two Different Intranasal Doses of Dexmedetomidine in Children for Magnetic Resonance Imaging Sedation.
Anaesthetic agents used for magnetic resonance imaging (MRI) in paediatric patients should cause few adverse effects and allow fast anaesthetic induction and recovery. The administration route is also important and should be minimally invasive. In this study, we aimed to compare two different doses of intranasal dexmedetomidine applied to children for MRI sedation. ⋯ Based on lower rescue anaesthetic requirements, sufficient sedation and parental separation scores in Group 2, intranasal dexmedetomidine 4 µg kg(-1) was more efficient than intranasal dexmedetomidine 3 µg kg(-1). The intranasal route may be an alternative noninvasive route to apply drugs for MRI sedation in paediatric patients. Trial registration ClinicalTrials.gov: NCT02299232.
