Albuterol Dose-Response on Pulmonary Function Testing in Preterm Infants at Risk of Bronchopulmonary Dysplasia
In Brief
A Phase 4 clinical trial evaluating Varied albuterol dose response for Bronchopulmonary Dysplasia and Very Low Birth Weight. Completed, enrolled 14 participants across 1 site.
Detailed Summary
The purpose of this study is to help determine the best dose of inhaled albuterol sulfate in premature babies at risk of developing bronchopulmonary dysplasia (BPD). BPD is the chronic lung disease of prematurity and is associated with increased morbidity and mortality, longer hospital stays, and increased healthcare utilization. Albuterol is an inhaled medication frequently used in premature infants with chronic lung disease and in people with asthma. It is believed to be safe, but the optimal dose for infants is not clear. The investigators hypothesize that albuterol may help a subset of premature infants with lung disease, but they need to determine the best dose prior to doing research about how effective it is for chronic lung disease/BPD. Response to each of three doses of albuterol will be measure using pulmonary function tests.

Timeline
Interventions
Subjects will be evaluated in 3 sessions. The sessions will occur within a 7 day time span, beginning between 14 or more days from birth and at a corrected gestational age of 28w0d to 33w6d. In each session, pulmonary function tests (PFTs) will be performed prior to and 15 minutes after a dose of albuterol. The dose will be different in each session. In the first session, a sinlge dose of 180 micrograms (2 puffs) of albuterol sulfate via metered dose inhaler. The dose will be 270 micrograms in the second session and 360 micrograms in the third session. PFTs will be performed during quiet sleep while the baby is spontaneously breathing or while the baby is intubated and receiving mechanical ventilation. Resistance and compliance will be measured using the single breath occlusion technique.
