About this study

Official title: Comparing Safety and Efficacy of Dexmedetomidine and Propofol in Patients Requiring Sedation for MRI Scanning

This is a prospective, open label randomized study. The purpose of this study is to compare propofol with dexmedetomidine for pediatric monitored anesthesia care for MRI, specifically identifying important patient demographics and looking at important outcomes including adverse events.

Read the detailed description

Patients will be randomized to either arm of the study. Throughout the sedation and recovery period, all study patients will have careful, routine documentation of hemodynamics (blood pressure, heart rate, plus oximeter, respiratory rate) as well as sedation depth. Patients will remain in recovery room until they have maintained discharge criteria for 30 minutes.

What participants receive

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

  • DexmedetomidineDrug

    Also called Precedex

    An initial bolus of 2 mcg/kg of dexmedetomidine will be administered over 10 minutes. This bolus can be repeated up to 2 times if sedation conditions are not achieved. Once successful sedation has been achieved, a 1.5 mcg/kg/hr infusion is initiated until the MRI is complete.

  • PropofolDrug

    Also called Diprivan

    An initial bolus of 1mg/kg of propofol will be administered over 1 minute. This bolus can be repeated up to 2 times if sedation conditions are not achieved. Once successful sedation has been achieved, a propofol infusion of 125 mcg/kg/min is initiated until the MRI is complete.

Study groups in NCT01152021
Study groupRoleWhat they receive
Dexmedetomidine GroupActive comparatorDexmedetomidine given as 2mcg/kg bolus over 10 minutes followed by 1.5mcg/kg/hr infusion for duration of scan. The bolus may be repeated up to 2 times at any time during the sedation in the event that adequate sedation conditions (minimum Ramsay Sedation Score of 4) are not achieved. In the event that dexmedetomidine is unable to achieve motionless conditions, after a total of 3 boluses, 0.5 mg/kg IV pentobarbital may be administered at q1 minute intervals up to a maximum of 2 mg/kg, per established protocol.
Receives: Drug: Dexmedetomidine
Propofol GroupActive comparatorPropofol bolus at an initial dose of 1 mg/kg over 1 minute then up to two additional 1 mg/kg boluses may be administered (total 3 mg/kg) - each over a one (1) minute interval, waiting 30 seconds after completion of each bolus to reassess sedation level. Once a minimum Ramsey Sedation Score 4 is achieved, an infusion at 125 mcg/kg/min is initiated. It may be titrated to 300 mcg/kg/min. If there is movement or awakening the patient may be rebolused with no more than 2 doses of Propofol at 1 mg/kg over 1 minute, in the same dosing manner as described above, waiting 30 seconds between doses. If adequate sedation is not achieved, 0.5 mg/kg IV pentobarbital may be administered at q1 minute intervals up to a maximum of 2 mg/kg.
Receives: Drug: Propofol

What is being measured

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

  1. Number of Adverse Events During the Sedation and Recovery Period

    Adverse events will be described by type, system involvement and level of severity.

    Measured: During sedation, recovery period and overnight, up to 24 hours

Secondary outcomes (1)
  1. Clinical Parameters (Sedation Scales, Hemodynamic Variables, Clinical Observations)

    Sedation scores, mean arterial blood pressures, clinical observations during sedation and recovery period

    Measured: During sedation, recovery and overnight, up to 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dexmedetomidine and Propofol in people with Safety and Efficacy of Sedation Medications, run by Boston Children's Hospital at 1 site in United States.

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 4 inclusion and 7 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: stopped early, as of the sponsor's last update on 21 May 2019. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 21 May 2019). 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?

Number of Adverse Events During the Sedation and Recovery Period (time frame: During sedation, recovery period and overnight, up to 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 21 May 2019.
