The Effect of Intranasal Dexmedetomidine Premedication in Children Undergoing Adenotonsillectomy Suffering From Recent Mild Upper Respiratory Tract Infection

The purpose of this study is to detect the efficacy of intranasal dexmedetomidine as a premedication to general anesthesia in pediatric patients with respiratory comorbidities undergoing adenotonsillectomy.

Inclusion Criteria:

1. Children with recent mild URI or asthma.
2. aged from 3 to 10 years
3. ASA Physical Status II,
4. undergoing adenotonsillectomy

Exclusion Criteria:

1. Parental refusal of participation
