NCT02168387

Brief Summary

The purpose of this study is to evaluate whether a therapy that uses a machine called a continuous high frequency oscillator (CHFO) is more successful at removing mucus than medications that thin out the mucus.

Outcome Measures

Primary Outcomes (1)

  • Improvement of Atelectasis

    An atelectasis score (AS), as published by Deakins, et al. 2002, was assigned to each radiograph as follows: 0 Complete resolution of collapse 1. Partial collapse of 1 segment or lobe 2. Partial collapse of ≥ 2 segments or lobes 3. Complete collapse of 1 segment or lobe 4. Complete collapse of ≥ 2 segments or lobes In the event of inter-rater disagreement, the scores were averaged. Improvement was defined as any decrease in AS ≥ 0.5. Worsening was defined as an increase in AS ≥ 0.5 or escalation of respiratory support modality (i.e. high frequency ventilation).

    after 48 hours of therapy

Secondary Outcomes (2)

  • Change in Capnography (Vd/Vt)

    baseline and 48 hours

  • Change in Quantity and Quality of Suctioned Mucus

    baseline and 48 hours

Study Arms (2)

continuous high frequency oscillator (CHFO)

ACTIVE COMPARATOR

Subjects randomized to receive therapy with the CHFO will receive a 20 minute treatment every 6 hours for 48 hours.

Device: continuous high frequency oscillator (CHFO)

medication

ACTIVE COMPARATOR

Subjects randomized to receive the medications will receive acetylcysteine and dornase alfa, two medications frequently used in the treatment of atelectasis. The medications will alternate every 6 hours for 48 hours.

Drug: AcetylcysteineDrug: dornase alfa

Limitations and Caveats

Small sample size in a single center study. Children who were extubated prior to the end of the study were not accounted for, as this was not a primary endpoint.
