Trial summary

Acute viral bronchiolitis is the first cause of respiratory distress in infant. Airway inflammation increases the respiratory system resistances and dynamic hyperinflation. This leads to an increase in the work of breathing. Read more about this study

About this study

Acute viral bronchiolitis is the first cause of respiratory distress in infant. Airway inflammation increases the respiratory system resistances and dynamic hyperinflation. This leads to an increase in the work of breathing. In Chronic obstructive pulmonary disease patients as in neonates, prone position (PP) improves lung function and decreases the end expiratory lung volume. The investigators hypothesized that in infants with severe bronchiolitis, prone position reduces the intrinsic Positive End Expiratory Pressure (PEEPi) and the work of breathing (WOB). The investigator designed a prospective randomized crossover study with 16 infants younger than six months who need ventilatory support by nasal continuous positive airway pressure (nCPAP) for severe acute viral bronchiolitis. Work of breathing (product time pressure) and PEEPi will be estimated using an esophageal pressure probe in prone and supine position.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Supine then Prone positionProcedure or surgery

    One hour in supine position with CPAP (+7 cmH2O) then 15 min in supine position in spontaneous ventilation (wash-out) and one hour in prone position with CPAP (+7 cmH2O)

  • Prone then supine positionProcedure or surgery

    One hour in prone position with CPAP (+7 cmH2O) then 15 min in supine position in spontaneous ventilation (wash out ) and one hour in supine position with CPAP (+7 cmH2O)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Work of breathing

    The primary outcome is the work of breathing (WOB) estimated by the mean on 100 breaths of the esophageal and trans-diaphragmatic Pressure-Time Product (PTP) at the end of the first hour.

    Measured: 60 min

Secondary outcomes (7)
  1. Intrinsic PEEP

    Mean on 10 breaths of the intrinsic positive end expiratory pressure in spontaneous ventilation

    Measured: 60 min

  2. Inspiratory:Expiratory Time Ratio

    Mean on 100 breaths of the Inspiratory:Expiratory Time Ratio

    Measured: 60 min

  3. Heart rate

    Evolution of the clinical and oxygenation parameter within the first hour in each position.

    Measured: 60 min

  4. Respiratory rate

    Evolution of the clinical and oxygenation parameters within the first hour in each position.

    Measured: 60 min

  5. SPO2

    Evolution of the clinical and oxygenation parameters within the first hour in each position.

    Measured: 60 min

  6. Transcutaneous CO2

    Evolution of the clinical and oxygenation parameters within the first hour in each position.

    Measured: 60 min

  7. EDIN score (neonatal pain and discomfort scale)

    Measured: 60 min

Questions about this trial

What is this clinical trial studying?

A study testing Supine then Prone position and Prone then supine position in people with Severe Bronchiolitis, run by Hospices Civils de Lyon at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Work of breathing (time frame: 60 min). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02602678, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2025.
