About this 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:

1. Can eligible patients be successfully enrolled and complete study procedures across multiple sites? 2. What safety events occur with early BPAP use in this population? 3. 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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

5 to 17 years of age (inclusive) presenting to the ED with an asthma exacerbation.

Demonstrate moderate-severe asthma exacerbation at triage (i.e., receive an institutional asthma score equivalent to moderate-severe asthma exacerbation or a Pediatric Respiratory Assessment Measure (PRAM) score of 6 or above).

Disqualifiers

Prior participation in the study.

Use of BPAP at any time within approximately 12 hours for this acute asthma exacerbation, including in prehospital, ED, or inpatient settings, prior to randomization.

Receipt of continuous albuterol for over 150 minutes prior to being approached for consent.

If a blood gas is obtained, PaCO2 greater than 60 mmHg on the most recent blood gas prior to being approached for consent.

Design model

Parallel

Treatments tested in this trial

  • Bilevel positive airway pressure ventilation

    Device

    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.

Treatment groups

36 Participants
are divided into 2 treatment groups
Group A: BPAP plus continuous albuterolExperimental treatment 1 intervention
Group B: Continuous albuterol aloneNo intervention 0 interventions

Trial outcomes

Primary outcomes

1

Number of eligible patients who consent

Proportion of approached, eligible patients who provide consent.

Time frame
From screening through randomization, up to 2 hours
2

Proportion of participants who adhere to the BPAP protocol among all those assigned to the BPAP arm

Proportion of participants in the intervention arm who receive \> 1 hour \& 45 minutes of BPAP during the planned 2-hour intervention period without unplanned interruption (\> 15 consecutive minutes), unless weaned off continuous albuterol.

Time frame
From randomization through end of 2-hour intervention

Secondary outcomes

1

Potential efficacy outcome: Change in Pediatric Respiratory Assessment Measure (PRAM) score

Change in Pediatric Respiratory Assessment Measure (PRAM) score from the pre-intervention to post-intervention assessment. The PRAM score ranges from 0 to 12, with higher scores indicating greater acute asthma exacerbation severity. Scores are categorized as mild (0-3), moderate (4-7), and severe (8-12).

Time frame
Pre-intervention to end of intervention, approximately 3 hours total
2

Potential efficacy outcome: Duration of continuous albuterol use

Duration of continuous albuterol therapy

Time frame
From randomization through hospital discharge beyond the intervention period, up to 120 hours.
3

Potential efficacy outcome: Duration of BPAP use

Duration of BPAP use

Time frame
From randomization through hospital discharge beyond the intervention period, up to 120 hours
4

Potential efficacy outcome: PICU admission

Proportion of participants requiring admissions to the pediatric intensive care unit during the index ED visit

Time frame
Disposition determined 2 hours after completion of the intervention period
