Positive Airway Pressure on Pleural Effusion After Drainage

Not Applicable

Completed

• Conditions: Pleural Effusion

• Registration Number: NCT02246946
• Lead Sponsor: Universidade Cidade de Sao Paulo

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Duration of chest tube drainage	All patients will be followed for the duration of hospital stay, an expected average of 7 days of chest 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

Secondary Outcome Measures

Name	Time	Method
Length of hospital stay	All patients will be followed for the duration of hospital stay, an expected average of 10 days	The number of days in the hospital after chest drainage until discharge will be counted for each patient
Spirometry	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	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
Pulmonary complications	All patients will be followed for the duration of hospital stay, an expected average of 10 days	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%)
Peripheral Oxygen Saturation	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	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.
