Outcomes of dexmedetomidine sedation for drug-induced sleep ciné magnetic resonance imaging studies in pediatric obstructive sleep apnea patients.

Dexmedetomidine alone or along with ketamine provided acceptable sedation in majority of the patients with obstructive sleep apnea undergoing outpatient diagnostic sleep magnetic resonance imaging studies without significant respiratory adverse events regardless of the severity of sleep apnea. Sedation failure and unplanned admissions are rare, and routine planned admission may not be required for this patient population.
