Abstract BACKGROUND: This prospective, randomized, double-blind study was designed to evaluate the use of intranasally administered dexmedetomidine vs intranasal midazolam as a premedication in children undergoing complete dental rehabilitation. METHODS: Seventy-two children of American Society of Anesthesiology classification (ASA) physical status (I & II), aged 3-6 years, were randomly assigned to one of two equal groups. Group M received intranasal midazolam (0.2 mg·kg(-1)), and group D received intranasal dexmedetomidine (1 μg·kg(-1)). The patients' sedation status, mask acceptance, and hemodynamic parameters were recorded by an observer until anesthesia induction. Recovery conditions, postoperative pain, and postoperative agitation were also recorded. RESULTS: The median onset of sedation was significantly shorter in group M 15 (10-25) min than in group D 25 (20-40) min (P = 0.001). Compared with the children in group M, those in group D were significantly more sedated when they were separated from their parents (77.8\% vs 44.4\%, respectively) (P = 0.002). Satisfactory compliance with mask application was 58.3\% in group M vs 80.6\% in group D (P = 0.035). The incidences of postoperative agitation and shivering were significantly lower in Group D compared with group M. Thirteen children (36.1\%) in group M, showed signs of nasal irritation with teary eyes, and none of these signs was seen in the children in group D (P = 0.000). There were no incidences of bradycardia, hypotension, in either of the groups during study observation. CONCLUSION: Intranasal dexmedetomidine (1 μg·kg(-1)) is an effective and safe alternative for premedication in children; it resulted in superior sedation in comparison to 0.2 mg·kg(-1) intranasal midazolam. However, it has relatively prolonged onset of action. © 2013 John Wiley & Sons Ltd.
