About this study

Official title: Efficacy of the Addition of Positive Airway Pressure to Conventional Chest Physiotherapy in the Time to Resolution of Pleural Effusion After Drainage

The purpose of this study is to determine if the addition of intermittent positive airway pressure breathing (specific lung expansion technique) to conventional chest physiotherapy chest drainage is effective to accelerate the reabsorption of pleural effusion and consequently decrease the duration of chest tube drainage and respiratory system impairment. These effects would decrease hospital stay lengths and the incidence of pulmonary complications.

What participants receive

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

  • Positive Airway PressureDevice

    To this group, Intermittent Positive Airway Pressure Breathing with 15 mmHg by Muller Reanimatior (Engemed, Brazil) device with a rubber facial mask will be provide

  • Conventional Chest PhysiotherapyOther

    To this group, routine physiotherapy exercises will be conducted plus Intermittent Positive Airway Pressure Breathing with 4 mmHg by Muller Reanimatior (Engemed, Brazil) device with a rubber facial mask will be provide

  • Control groupProcedure or surgery

    to this group, Airway Pressure Breathing with 4 mmHg by Muller Reanimatior (Engemed, Brazil) device with a rubber facial mask will be provide

Study groups in NCT02246946
Study groupRoleWhat they receive
Positive Airway Pressure groupExperimentalThe patients allocated to this group will undergo bronchial hygiene treatments administered with a high-frequency oscillator for 5 sets of 10 repetitions, lung expansion exercises using flow oriented incentive spirometry for 5 sets of 20 repetitions and walking for 100 meters (i.e., the same treatment that will be administered to the Conventional Chest Physiotherapy group). Additionally, this group will receive positive airway pressure breathing with 15 mmHg by a device via a rubber facial mask for 30 minutes in a sitting position.
Receives: Device: Positive Airway Pressure
Conventional Chest Physiotherapy groupActive comparatorIn the sitting position, the patients allocated to this group will undergo bronchial hygiene treatments administered with a high-frequency oscillator for 5 sets of 10 repetitions, lung expansion exercises using flow oriented incentive spirometry for 5 sets of 20 repetitions and positive airway pressure breathing with 4 mmHg via a rubber facial mask for 5 minutes in a sitting position. These patients will also walk for 100 meters. The use of positive pressure breathing with 4 mmHg has no therapeutic value, but will help keep the blinding of assessors by the presence of the equipment in the room and mark the patient's skin.
Receives: Other: Conventional Chest Physiotherapy
Control groupPlacebo comparatorThe patients allocated to this group will receive positive airway pressure breathing with 4 mmHg (without therapeutic value) via a rubber facial mask for 30 minutes in a sitting position. The use of positive pressure breathing with 4 mmHg has no therapeutic value, but will help keep the blinding of assessors by the presence of the complete kit of equipment in the room.
Receives: Procedure: Control group

What is being measured

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

  1. Duration of chest tube drainage

    The criteria for the removal the chest drain will an output of transudative fluid over 24h ≤ 200 ml and full lung expansion on chest radiography

    Measured: All patients will be followed for the duration of hospital stay, an expected average of 7 days of chest drainage

Secondary outcomes (4)
  1. Spirometry

    The blind assessor will use a portable spirometer according previously established implementation and acceptability criteria. The following variables will be considered: forced vital capacity, forced expiratory volume in the 1st second, and forced expiratory flow between 25% and 75% of the curve. The predictive values for the Brazilian population will be used

    Measured: On the 4th and 8th days after the beginning of the intervention protocol. Or on the day of hospital discharge if it occurs prior to the 8th day of protocol

  2. Peripheral Oxygen Saturation

    The patients will be required to breath room air (without supplemental oxygen) for at least 10 minutes prior to the assessments. The blind assessor will use a portable pulse oximeter.

    Measured: On the 4th and 8th days after the beginning of the intervention protocol. Or on the day of hospital discharge if it occurs prior to the 8th day of protocol

  3. Pulmonary complications

    The occurrence of the following complications will be monitored until the day of hospital discharge by a physician blinded to the intervention groups: pneumonia (chest radiography with pulmonary infiltrate associated with two of the following signs: purulent expectoration, temperature above 38.3°C and a greater than 25% increase in baseline leukocyte count with hyperthermia); atelectasis (RX associated with abnormal chest acute respiratory symptoms); and hypoxemia (peripheral oxygen saturation associated with respiratory symptoms below 85%)

    Measured: All patients will be followed for the duration of hospital stay, an expected average of 10 days

  4. Length of hospital stay

    The number of days in the hospital after chest drainage until discharge will be counted for each patient

    Measured: All patients will be followed for the duration of hospital stay, an expected average of 10 days

Questions about this trial

What is this clinical trial studying?

A study testing Positive Airway Pressure and Conventional Chest Physiotherapy in people with Pleural Effusion, run by Universidade Cidade de Sao Paulo at 1 site in Brazil.

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 1 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 18 Jan 2017. 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 Brazil. 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. Some participants in this study may receive a placebo. 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?

Duration of chest tube drainage (time frame: All patients will be followed for the duration of hospital stay, an expected average of 7 days of chest drainage). 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 NCT02246946, which also lists 2 linked publications.

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 18 Jan 2017.
