SummaryIntranasal dexmedetomidine has been used successfully for sedation in children. A mucosal atomisation device delivers an atomised solution to the nasal mucosa which facilitates rapid and effective delivery of medication to the systemic circulation. We compared intranasal delivery of dexmedetomidine in a dose of 3 lg.kg À1 by either atomiser or drops from a syringe in children < 3 years old undergoing transthoracic echocardiography. Two hundred and seventy-nine children were randomly assigned to one or other group. One hundred and thirty-seven children received dexmedetomidine by atomiser and 142 by drops. The successful sedation rate was 82.5% (95% CI 75.3-87.9%) and 84.5% (95% CI 77.7-89.5%) for atomiser and drops, respectively (p = 0.569). Sedation tended to be less successful in older children (p = 0.028, OR 0.949, 95% CI 0.916-0.983). There were no significant complications. We conclude that both modes of dexmedetomidine administration are equally effective, although increasing age of the child was associated with a decreased likelihood of successful sedation.
SummaryChloral hydrate is the most commonly used sedative for paediatric diagnostic procedures in China with a success rate of around 80%. Intranasal dexmedetomidine is used for rescue sedation in our centre. This prospective investigation evaluated 213 children aged one month to 10 years who were not adequately sedated following administration of chloral hydrate. Children were randomly assigned to receive rescue intranasal dexmedetomidine at 1 lg.kg À1 (group 1), 1.5 lg.kg À1 (group 2) or 2 lg.kg À1 (group 3). The sedation level was assessed every 10 min using a modified observer's assessment of alertness/sedation scale. Successful rescue sedation in groups 1, 2 and 3 were 56 (83.6%), 66 (89.2%) and 51 (96.2%), respectively. Increasing the rescue dose was associated with an increased success rate with an odds ratio of 4.12 (95% CI 1.13-14.98), p = 0.032. We conclude that intranasal dexmedetomidine is effective for sedation in children who do not respond to chloral hydrate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
