Atomised intranasal dexmedetomidine versus oral melatonin in prevention of emergence delirium in children undergoing ophthalmic surgery with sevoflurane: A randomised double-blind study.

Background: Melatonin and dexmedetomidine have both been used as a premedication to decrease emergence delirium in children. The effectiveness of oral melatonin, compared with atomised intranasal dexmedetomidine, in this role is not well studied.

Objective: To study the efficacy of pre-operative atomised intranasal dexmedetomidine versus oral melatonin in children scheduled for ophthalmic surgery under sevoflurane.
