Respiratory comorbidities are associated with an increased incidence of peri-operative respiratory adverse effects (PRAE).~Upper and lower respiratory infections, as well as asthma, are common in children who are scheduled for adenotonsillectomy. When compared to healthy children, children with respiratory ailments have a three-fold increase in PRAEs.
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.
