Randomized Controlled Trial Comparative Study
A randomised comparison of two intranasal dexmedetomidine doses for premedication in children.
We compared sedation levels in children following administration of intranasal dexmedetomidine. One hundred and sixteen children aged between 1 and 8 years were enrolled in this prospective, randomised trial. Children were assigned to receive either intranasal dexmedetomidine 1 μg.kg(-1) (Group 1) or 2 μg.kg(-1) (Group 2). ⋯ Both doses produced a similar level of satisfactory sedation in children aged 1-4 years, whereas 2 μg.kg(-1) resulted in a higher proportion of satisfactory sedation in children aged 5-8 years. There were no adverse haemodynamic effects. We conclude that intranasal dexmedetomidine in a premedication dose of 2 μg.kg(-1) resulted in excellent sedation in children.
