Oral Dexmedetomidine Versus Midazolam as Anesthetic Premedication in Children Undergoing Congenital Heart Surgery.

Background: Premedication is required for reducing anxiety and child's struggling against mask acceptance on anesthesia in pediatric surgery for congenital heart disease. Midazolam has been widely used for this purpose, but because of its side effects, finding an effective replacement with less complication is necessary.

Objectives: In the present study, we compared the efficacy of oral midazolam versus dexmedetomidine in terms of anxiolysis and mask acceptance behavior.
