Evaluation on the Efficacy of Bronchodilator Nebulization Via High Flow Nasal Cannula

April 2, 2018 updated by: Jie Li, Rush University Medical Center
High-humidity nasal cannula (HFNC) has been shown to be effective in improving oxygenation and avoiding intubation in multiple randomized control trials, it is also suitable and feasible for long term use. Aerosol delivery via HFNC will minimize interruptions and improve patient compliance, bench study and radionuclide imaging study done in healthy volunteers demonstrated that aerosol can be effectively delivered using HFNC. This study aims to evaluate the efficacy of bronchodilator delivered via HFNC in chronic pulmonary obstructive disease or asthma patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Chronic obstructive pulmonary disease or asthma patients who have positive response in bronchodilator test will be consented and enrolled, patients come back for the second bronchodilator assessment within one to three days after the initial bronchodilator test. Albuterol with different concentration will be provided to the patients via HFNC, patients will be assessed by spirometry after each concentration until bronchodilator response is positive and does not improve after the next dose.

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.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Albuterol via High flow nasal cannula
Enrolled patients inhale bronchodilator (Albuterol Sulfate) with different concentration via High flow nasal cannula, prepared albuterol concentrations are 0.5mg, 1.0mg, 2.0mg and 4.0mg, patients will be assessed by spirometry after each concentration until bronchodilator response is positive and does not improve after the next dose.
Device: High flow nasal cannula
High flow nasal cannula is a soft and flexible nasal prongs with adjustable head strap fits over the patient's ears, it delivers a broad variety of gas flows directly into the nares without gas jetting.

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.
