Summary

The primary objective will be, in an open-label randomized trial, a comparison of emergency department (ED) length of stay (LOS) between children experiencing acute asthma treated with two different nebulizers. Secondary outcomes will include admission rates, hospital LOS, need for additional therapies, transfers to a higher level of care, side-effects, and unscheduled return visits

Detailed description

To our knowledge, no study has compared a breath-enhanced nebulizer to a standard jet nebulizer for the treatment of acute asthma in children. The goal of this study is to determine whether a rapid albuterol delivery pathway with a breath-enhanced nebulizer can reduce ED LOS, while maintaining admission rates, repeat visits, adjunctive therapies, and side-effects, when compared to a traditional asthma pathway with a standard jet nebulizer. The Salter® Nebutech® HDN® was chosen because its breath-enhanced design and bolus delivery system may deliver greater amounts of albuterol to the small airways, in a shorter period of time, when compared with standard jet nebulizers and other nebulizers in its class. The study site will be a large, urban pediatric emergency department (ED) with approximately 80,000 visits per year. The study protocol will be submitted to the hospital's Institutional Review Board (IRB) for approval. Children will be eligible for enrolment if they are between 3 and 18 years of age and present to the ED with an acute asthma exacerbation of at least moderate severity. The lower age cutoff was chosen because asthma diagnosis and beta agonist response can be unreliable in younger children. The upper age cutoff was chosen to include only pediatric patients, as this is a pediatric asthma study. Children must have a history of physician-diagnosed asthma as reported by the parent or guardian. Children will be enrolled when a research team member is available to obtain informed consent (convenience sample). Children will be excluded from enrollment if the initial pediatric asthma score (PAS) is \< 3, immediate resuscitation is required, they have a history of chronic lung disease or congenital heart disease, they have any neuromuscular disease, intrathoracic foreign body is suspected, they are or may be pregnant, they are currently breast feeding, they have received oral or parenteral steroids within the last week (inhaled steroids are allowed), or they have an allergy or other contraindication to one of the study medications. Potential subjects will be identified in triage and screened for enrolment if study personnel are available. If consented, the patient will be randomized to one of the two treatment arms. If there will be greater than a 15 minute delay in treatment due to the consent process, unit dose (2.5 mg) albuterol treatments will be given with a standard nebulizer up to 3 times as needed. That patient may still be enrolled provided he/she still meets inclusion/exclusion criteria.

Interventions

Type	Name	Description
DEVICE	Hudson RCI® nebulizer	After the first hour of treatment, patients in the standard arm will receive a repeat assessment, including all of the measurements collected at baseline as well as reported side effects. Those patients who score PAS 0-2 will then be discharged home, after an optional observation period, as per the pathway. Those who score PAS \> 2 will receive a second treatment. At the end of the second treatment patients will again be re-assessed, and repeat measurements obtained. At that time, depending on the patient's PAS score, he/she will be dispositioned to home, the floor, the pulmonary high acuity unit (PHAU), or the pediatric intensive care unit (PICU).
DEVICE	NebuTech® HDN® nebulizer	All treatments in the NebuTech® arm will be given at a standard dilution of 5 ml (diluted with normal saline to a total volume of 5 ml as per the manufacturer's recommendation). Patients in this arm will receive up to four treatments with parameters measured after each treatment, similar to the control arm. Patients who complete four treatments will then be dispositioned based on PAS score, similar to the control arm. Subjects may have started treatment prior to consent and may receives unit dose (2.5 mg) Albuterol/Proventil treatments will be given with a standard nebulizer up to 3 times as needed and may change over to study randomized device once consented to eith arm.
DRUG	Albuterol	Subjects may have started treatment prior to consent and may receives unit dose (2.5 mg) Albuterol/Proventil treatments will be given with a standard nebulizer up to 3 times as needed and may change over to study randomized device once consented to eith arm.
