Inhaled Hypertonic Saline for Bronchiolitis (7HSinED)

November 12, 2015 updated by: Dr. Michael Flavin, Queen's University

7% Hypertonic Saline to Treat Bronchiolitis in the Emergency Department

Study Design: This randomized, double blind, controlled, multi-centre study will occur in the Emergency Department, hospital-based Urgent Care Centre or paediatric outpatient clinics (collectively "ED") of 3 General Hospitals in Ontario and 1 in British Columbia.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Children under age 2 years presenting for unscheduled care to the ED with a diagnosis of moderately severe bronchiolitis (as defined by inclusion/exclusion criteria below) will be approached for entry into the study. Recruitment will only occur when Research Assistants are on duty, is projected to include regular working hours Monday-Friday as a minimum and will continue until the calculated sample size has been obtained (anticipated 12 months). Initial routine assessment by the ED staff will identify potential subjects and Research Assistants will be notified to apply the inclusion/exclusion criteria and obtain informed consent if appropriate. Recruited subjects will be randomized to receive treatment in a double blind fashion with inhalation of nebulized study solution containing either 7% hypertonic saline (HS, study group) or 0.9% saline (NS, control group). Each dose of study solution will also contain a standard dose of bronchodilator (salbutamol, 0.15 mg/kg; 0.03 ml/kg of 0.5% salbutamol nebulizer solution) added by the ED staff. Each participant will remain on the same allocation throughout the protocol and receive 3 consecutive 4ml doses of the assigned study solution with salbutamol over a 1-hour period.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 weeks to 2 years (Child)

Accepts Healthy Volunteers

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The change in respiratory distress, as measured by the Respiratory Assessment Change Score (RACS),
Time Frame: 120 minutes after baseline pre-treatment
The response to treatment is determined by using the Respiratory Distress Assessment Instrument(RDAI) score and respiratory rate to calculate the Respiratory Assessment Change Score (RACS) i.e. RDAI score before minus RDAI score after treatment
120 minutes after baseline pre-treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
rates of admission to hospital
Time Frame: 7 days
7 days
length-of-stay of admitted patients
Time Frame: 28 days
28 days
rates of unscheduled return for respiratory illness to the ED
Time Frame: 14 days

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.

For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
