Overview
In Korea, oral chloral hydrate is still widely used for pediatric procedural sedation. The primary objective of the study is to evaluate the effect of intranasal dexmedetomidine (2mcg/kg) and ketamine (3mg/kg) on the first-attempt success rate of pediatric procedural sedation. The hypothesis of this study is that the intranasal dexmedetomidine (2mcg/kg) and ketamine (3mg/kg) will improve the success rate of adequate pediatric procedural sedation (PSSS=1,2,3) within 15 minutes. This is a prospective, parallel-arm, single-blinded, multi-center, randomized controlled trial comparing the effect of intranasal dexmedetomidine (2mcg/kg) and ketamine (3mg/kg) with oral chloral hydrate (50mg/kg) in pediatric patients undergoing procedural sedation. Prior to the procedure, each patient will be randomized in the control arm (oral chloral hydrate) or study arm (intranasal dexmedetomidine and ketamine).
