About this study
Official title: Bilevel Positive Airway Pressure (BPAP) for Severe Asthma Exacerbations: A Randomized Controlled Trial
The goal of this clinical trial is to assess the feasibility of early initiation of bilevel positive airway pressure (BPAP) in the emergency department (ED) for children with severe asthma exacerbations. It will also collect preliminary data on the safety and potential effectiveness of this approach.
The main questions it aims to answer are:
Read more
- Can eligible patients be successfully enrolled and complete study procedures across multiple sites?
- What safety events occur with early BPAP use in this population?
- How do clinical outcomes (such as symptom improvement and need for intensive care) compare between early BPAP and standard care?
Researchers will compare early initiation of BPAP plus standard asthma therapy to standard asthma therapy alone to determine whether early BPAP is a feasible and potentially beneficial treatment strategy.
Participants will 1) receive standard asthma therapy with or without early BPAP in the ED, 2) be monitored closely during the ED visit and hospitalization, and 3) have clinical data collected from routine care, including asthma severity scores, treatments, and outcomes.
The study will enroll approximately 36 participants (about 12 per site) across three sites over one year to inform a future multicenter randomized controlled trial.
Read the detailed description
Severe asthma exacerbations are a common reason for pediatric emergency department (ED) visits, hospital admissions, and pediatric intensive care unit (PICU) use. Although first-line therapies such as inhaled beta-agonists, anticholinergics, and systemic corticosteroids are well established, the optimal second-line treatment for children who remain in moderate to severe respiratory distress is unclear.
Bilevel positive airway pressure (BPAP) is a form of non-invasive positive pressure ventilation that may improve airway patency, reduce work of breathing, improve ventilation-perfusion matching, and enhance delivery of inhaled bronchodilator therapy. Prior pediatric studies suggest potential physiologic and clinical benefit, but available randomized trials have been small and have generally evaluated BPAP after PICU admission rather than early in the ED course. Therefore, the feasibility, safety, and potential clinical impact of early ED initiation of BPAP remain uncertain.
This multicenter, randomized, unblinded feasibility trial will enroll approximately 36 children across three sites. Participants will be children with severe asthma exacerbations who remain symptomatic after completion of standard first-line therapy and continue to require continuous albuterol. Patients will be randomized to receive either BPAP plus continuous albuterol or continuous albuterol alone during an approximately 2-hour intervention period. BPAP will be delivered using FDA-cleared devices, with mask interface and pressure settings managed according to routine clinical practice. After the intervention period, all further asthma treatment and respiratory support will be determined by the treating clinical team.
The primary purpose of this study is to assess feasibility of conducting a future definitive multicenter randomized trial. Feasibility domains include patient identification, consent and assent processes, timely randomization, BPAP initiation and adherence, completion of asthma severity assessments, and collection of clinical and safety data. Clinical outcomes, including asthma severity, duration of continuous albuterol, BPAP use, ED disposition, PICU and hospital admission, length of stay, and readmission, will be summarized descriptively. Safety monitoring will include adverse events potentially related to BPAP or continuous albuterol, including air leak syndrome, vomiting, aspiration, hypotension, skin breakdown, tachycardia, and tremor.
This feasibility trial is not powered to detect treatment efficacy. Results will be used to refine trial procedures, assess protocol adherence, estimate enrollment and data completion rates, and inform the design of a future multicenter randomized trial evaluating whether early ED initiation of BPAP reduces critical care resource use and improves outcomes in children with severe asthma exacerbations.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bilevel positive airway pressure ventilationDevice
This study involves non-invasive positive pressure ventilation (NIPPV) delivered as bilevel positive airway pressure (BPAP) in children aged 5-17 years presenting to the pediatric emergency department with severe asthma exacerbations. BPAP will be administered using FDA-cleared devices according to their intended use and standard clinical practice. Therapy will be delivered via an appropriately fitted nasal or face mask and managed by trained clinical staff. Ventilator settings will be adjusted at the discretion of the treating clinician, and continuous bronchodilator therapy may be delivered through the BPAP circuit per manufacturer recommendations or site practice.
| Study group | Role | What they receive |
|---|---|---|
| BPAP plus continuous albuterol | Experimental | Participants randomized to this arm will receive BPAP plus continuous albuterol administered via FDA-approved delivery systems according to routine clinical practice. BPAP will be delivered using an appropriately sized nasal or face mask and managed by trained respiratory therapists and/or nursing staff per standard care. Continuous albuterol will be administered through the BPAP circuit per manufacturer recommendations or site-specific practice. BPAP settings may be adjusted at the discretion of the treating clinician. Participants will remain on BPAP for approximately 2 hours or until continuous albuterol is discontinued, whichever occurs first. After the intervention period, continuation of BPAP will be at the treating clinical team's discretion. Receives: Device: Bilevel positive airway pressure ventilation |
| Continuous albuterol alone | No intervention | Participants randomized to this arm will receive continuous albuterol administered via FDA-approved delivery systems according to routine clinical practice. Non-invasive ventilation (including BPAP or CPAP) will not be initiated during the first approximately 2 hours after randomization unless clinically indicated; if initiated, the reason will be documented. All other aspects of care, including oxygen and adjunctive therapies, will be provided at the discretion of the treating clinical team per standard practice. After the intervention period, escalation of care, including initiation of BPAP or other respiratory support, will be determined by the treating clinician. |
