Trial summary

Croup affects 5% of children under 6 years of age, resulting in visits to hospital Emergency Departments, and in 1% of children, hospitalization. Traditionally, the first therapy offered is humidification which can liquify airway secretions and decrease airway swelling. Read more about this study

About this study

Official title: Efficacy of Optimal Versus 'Traditional' Delivery of Humidity in Children With Croup

Croup affects 5% of children under 6 years of age, resulting in visits to hospital Emergency Departments, and in 1% of children, hospitalization. Traditionally, the first therapy offered is humidification which can liquify airway secretions and decrease airway swelling. This study will compare the effectivenesss of 40% and 100% humidity through a specially designed machine called a nebulizer, with the usual humidity set-up (blown into the patient's face from a hose).

What is being measured

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

  1. changes in the croup score from baseline to 30 and 60 minutes

Secondary outcomes (3)
  1. steroid or epinephrine treatment at 60 minutes

  2. discharge rate at 60 minutes

  3. change in pulse, respiratory rate, and oxygen saturation at 60 minutes

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing nebulized humidity in people with Croup, run by The Hospital for Sick Children at 1 site in Canada.

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 2 inclusion and 8 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 2 Aug 2013. 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 Canada. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

changes in the croup score from baseline to 30 and 60 minutes. 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 NCT00230841, which also lists 1 linked publication.

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 2 Aug 2013.
