About this study

Official title: Effectiveness of Chest Physiotherapy in Infants Hospitalized With Acute Bronchiolitis SRV (+): a Randomized Controled Trial

The purpose of this research is to determine the effect of prolonged slow expiration techniques, provoked coughing and standard therapy compared to chest wall manual vibration and standard therapy in infants between 0 and 12 months old with confirmed diagnosis of acute bronchiolitis SRV (+). The effect will be measured on respiratory insufficiency and use of supplementary oxygen.

Read the detailed description

Bronchiolitis is the main cause of hospital admission for infants under 1 year old in Chile. Currently, approximately 4800 children are admitted to the hospital during the cold season, affecting the health services' effectiveness. The most frequent causal agent is the Respiratory Syncytial Virus (RSV). To date, there is no specific treatment for this disease and only support measures are recommended.

Chest physiotherapy is a support measure that improves the mucociliary clearance and reduces obstruction of the airways.

A clinical trial on the effect of prolonged slow expiration (PSE), chest wall vibrations, and provoked coughing as treatment for bronchiolitis in infants admitted to the hospital found that the subgroup with RSV required oxygen for 10 hours less than the control group. Gomes and Postiaux (2012) reported a 50% decrease on respiratory distress measured by the Wang score when PSE and suction were compared to traditional chest physiotherapy techniques in patients with bronchiolitis RSV(+).

Currently recommendations in Chile suggest chest physiotherapy for outpatients with bronchiolitis, but the guideline does not refer to the case of inpatients. It is proposed to carry out a randomized controlled trial in infants under one year old. The active group will receive standard therapy, PSE, and provoked coughing, while the control group will receive standard therapy and manual chest wall vibrations. The effectiveness of chest physiotherapy will be measured though a clinical score of respiratory distress, hours using supplementary oxygen, vital signs before and after the intervention in both groups during hospital stay. The main outcome is clinical severity score 48 hours after admission.

What participants receive

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

  • Prolonged slow expiration+provoked coughingOther

    Five cycles of prolonged slow expiration and provoked coughing, which will be repeated five times.

    During the prolonged slow expiration, the infant will be in supine while the therapist applies pressure at the same time on the rib cage and abdomen during spontaneous expiration. The pressure is applied slowly during two o three respiratory cycles, only during the final phase of expiration.

  • Manual chest wall vibrationOther

    Five cycles of manual chest wall vibrations during 20 seconds each, being repeated five times.

    The manual chest wall vibrations are oscillatory maneuvers applied on the thorax to improve mucociliary clearance of bronchial mucus and ease its removal.

  • Standard TherapyOther

    Standard therapy (ST): nasopharyngeal suction, oxygen therapy, fluids administration, 0.5% adrenaline nebulization, and chest physiotherapy.

Questions about this trial

What is this clinical trial studying?

A study testing Prolonged slow expiration+provoked coughing, Manual chest wall vibration and Standard Therapy in people with Bronchiolitis, Viral, run by Universidad del Desarrollo at 1 site in Chile.

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 3 inclusion and 6 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 26 Oct 2016. 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 Chile. 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?

Clinical score of respiratory distress (time frame: 48 hours after baseline measurement). 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 NCT02853838, 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 26 Oct 2016.
