Intranasal Dexmedetomidine VS Oral Chloral Hydrate for Rescue Sedation During Magnetic Resonance Imaging
A Phase 4 study testing chloral hydrate Group, low dose dexmedetomidine group and high dose dexmedetomidine group in people with Administration Related Reaction and Failed Moderate Sedation During Procedure, run by Guangzhou Women and Children's Medical Center at 2 sites in China.
Trial summary
The purpose of this investigation was to test the hypothesis that intranasal dexmedetomidine is as effective as second dose of oral chloral hydrate for rescue sedation in infant age between 1 and 6 months who were not adequately sedated following initial dose of chloral hydrate.

What is being measured
The primary outcome is the main question the study is designed to answer.
successful rescue sedation rate
Sedation status was evaluated by a attending anesthesiologists every 5-10 min with a 6-point sedation scale, which was modified from the Observer Assessment of Alertness and Sedation Scale (MOAA/S; Table 1).
successful sedation was defined as an MOAA/S of between 0 and 3
Measured: up to 1 hours after MRI scaning
Secondary outcomes (2)
sedation induction time
Successful sedation was defined as an MOAA/S of between 0 and 2, and sedation induction time was defined as the time from rescue drug administration to the onset of satisfactory sedation
0 Does not respond to a noxious stimulus
- Does not respond to mild prodding or shaking
- Responds only after mild prodding or shaking
- Responds only after name is called loudly orrepeatedly
- Lethargic response to name spoken in normal tone
- Appears asleep, but responds readily to namespoken in normal tone
- Appears alert and awake, responds readily to namespoken in normal tone
Measured: up to 30 min after rescue drug administration
Wake -up time
Children were classified as awake if the MOAA/S was between 4 and 6. Wake -up time was defined as the time from successful sedation until the time that the child awoke
Measured: up to 4 hours after rescue drug administration

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing chloral hydrate Group, low dose dexmedetomidine group and high dose dexmedetomidine group in people with Administration Related Reaction and Failed Moderate Sedation During Procedure, run by Guangzhou Women and Children's Medical Center at 2 sites in China.
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 1 inclusion and 1 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 12 May 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in China. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
successful rescue sedation rate (time frame: up to 1 hours after MRI scaning). 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 NCT02239445, which also lists 3 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 12 May 2015.
