Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Children were randomly allocated to one of the three groups to receive premedication either placbo (Group S), dexmedetomidine 1microg/kg (Group D1), or dexmedetomidine 2microg/kg (Group D2) in a double-blinded fashion according to random list generated by a computer. Allocation was concealed by the method of sealed opaque envelopes .
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Masking / blinding

Summary
Brief summary
Sevoflurane is widely employed for inhalational induction of general anaesthesia in children. There is increasing evidence that dexmedetomidine is an effective and safe sedative in children. Laryngeal mask airway is an useful device for pediatric anesthesia. The aim of the current study was to determine whether Intranasal dexmedetomidine premedication can reduce MAC of sevoflurane for an LMA insertion in children
