Sedation in pediatric imaging using intranasal midazolam.

Intranasal midazolam offers an attractive alternative for use as a sedative agent for medical imaging studies in children. Its convenient administration and rapid onset are significant advantages over intravenous and oral agents. Because of its short duration, it is effective only for short procedures and as an adjunct to other sedative agents. When younger children present with such requirements, a dose of 0.2 mg/kg has been safe and effective in our experience. We advocate its use with adherence to guidelines for sedation published by the American Academy of Pediatrics.
