Dexmedetomidine as a pediatric anesthetic premedication to reduce anxiety and to deter emergence delirium.

Presurgery anxiety in children may result in preoperative and postoperative complications. Emergence delirium (ED) is a mental disturbance common in children during recovery from general anesthesia. This study investigated the role of preoperative dexmedetomidine on parental separation anxiety and acceptance of wearing an anesthesia mask, and its effectiveness in reducing the incidence and severity of ED.
