  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Patients with documented history of OSA by polysomnography who require anesthesia for MRI sleep study or MRI brain imaging study.

About this study

Official title: 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.

Read the detailed description

Patients with OSA are at risk for airway obstruction (a condition that makes it difficult to breath) during sedation and anesthesia. Dexmedetomidine and propofol are safe and effective drugs regularly used by anesthesiologists. These drugs are used to put patients to sleep for operations and certain studies like MRI scans. However, there have been no studies describing the effects these drugs have on the upper airway of children, adolescents, and young adults with OSA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DexmedetomidineDrug

    Also called Precedex

    Once an IV is in place, atropine 10 mcg/kg will be given. Loading dose of dexmedetomidine 1 mcg/kg will be administered over 10 minutes followed by a continuous infusion of dexmedetomidine at rate of 1 mcg/kg/h using a syringe pump.

  • PropofolDrug

    Also called Diprivan

    Once an IV is in place, atropine 10 mcg/kg will be given. Loading dose of propofol 2 mg/kg will be administered over 2 minutes followed by a continuous infusion of propofol at rate of 100 mcg/kg/minute using a syringe pump.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cross Sectional Area of the Pharyngeal Airway

    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.

    Measured: during MRI within first 10 minutes of scanning

Secondary outcomes (4)
  1. Obstructive Index Until Recovery Room Discharge

    The Obstructive Index is a count of the obstructive apnea events per hour of sleep

    Measured: During MRI and until recovery room discharge - approximately 30-250 minutes

  2. Respiratory Disturbance Index

    The respiratory disturbance index is a count of respiratory disturbance events per hour of sleep.

    Measured: During MRI and until recovery room discharge - approximately 30-250 minutes

  3. Needed Artificial Airway

    This is the count of the number of patients who needed an artificial airway.

    Measured: During MRI and until recovery room discharge - approximately 30-250 minutes

  4. Room Air SpO2

    The patient's oxygen saturation on room air.

    Measured: During MRI and until recovery room discharge - approximately 30-250 minutes

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Feb 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cross Sectional Area of the Pharyngeal Airway (time frame: during MRI within first 10 minutes of scanning). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01344759, which also lists 33 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Aug 2018.
