Dexmedetomidine and Propofol in Children With History of Obstructive Sleep Apnea
Effect of Increasing Depth of Dexmedetomidine and Propofol Anesthesia on Upper Airway Morphology in Children With History of Obstructive Sleep Apnea
The purpose of this research study is to examine the effects of two commonly used anesthetic drugs, dexmedetomidine and propofol, have on the shape and muscle tone of the upper airway in children, adolescents, and young adults with a history of obstructive sleep apnea (OSA) having an MRI scan.
The results of this study will help in making the best decisions regarding the anesthesia medications that are most appropriate for children, adolescents, and young adults with OSA during MRI studies.

Genders Eligible for Study
Description
Inclusion Criteria:
- Patients with documented history of OSA by polysomnography who require anesthesia for MRI sleep study or MRI brain imaging study.
- Subjects must be 12 months to 25 years of age (inclusive)
- Either the subject (if subject's age is 18-25) or the subject's legally authorized representative has given written informed consent to participate in the study
Exclusion Criteria:
- The subject has life-threatening medical conditions (American Society of Anesthesiologists Physical Status 4, 5 or 6). The American Society of Anesthesiologists (ASA) classification scale is a measure of physical status or how healthy the patient is. For our study, we will focus on children which are defined as ASA I, II or III which means a healthy child (ASA I), a child with a systemic disease that is mild and well controlled (ASA II) or a child with systemic disease that is severe and controlled (ASA III).
- The subject is allergic to or has a contraindication to propofol or dexmedetomidine.
- The subject has a tracheostomy or other mechanical airway device
- The subject is not scheduled to receive anesthesia-sedation care for the MRI
- The subject has a history or a family (parent or sibling) history of malignant hyperthermia.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cross Sectional Area of the Pharyngeal Airway
Time Frame: during MRI within first 10 minutes of scanning
|
The primary outcome measures will be the cross sectional area of the pharyngeal airway of the patients measured at two levels soft palate (nasopharyngeal) and base of the tongue (retroglossal).
Magnetic resonance images of the airway were obtained during low (1 mcg/kg/hr) and high (3 mcg/kg/hr) doses of DEX or low (100 mcg/kg/m) and high (200 mcg/kg/m) doses of Propofol.
All were administered through an intravenous (IV) catheter.
