- Brief Summary
The aim of this study is to evaluate the effects of the use of breathing exercises with inspiratory loading on respiratory muscle strength and endurance, lung volumes and capacities and thoracoabdominal mobility in patients after bariatric surgery.
It is believed that the use of inspiratory load may mitigate the negative effects of surgical trauma on respiratory muscle dysfunction, preserving respiratory muscle strength, lung volumes and diaphragm mobility, thus reducing the risk of pulmonary complications in the postoperative period.
- Detailed Description
This is a prospective, randomized and blinded study, where volunteers will be selected anthropometric measurements, assessment of lung volumes and capacities, through spirometry, thoracoabdominal mobility through the circumference, assessment of inspiratory muscle strength and endurance.
After these evaluations will be done by lottery randomization, where the volunteers will be divided into five groups. They are: control, incentive spirometry to flow, the volume incentive spirometry, Threshold ™, Power breathe ®, according to their resources to be performed during the postoperative period. Each appeal will be held in 6 sets of 15 repetitions, totaling seven sessions, two in the immediate postoperative period, and five on the first postoperative day. At the end of the intervention volunteers will be reassessed.

- Primary Outcome Measures
Name Time Method EVALUATION OF INSPIRATORY MUSCLE ENDURANCE Preoperatively and on the high hostitalar - On day 1 and day 3 The endurance test is performed using the Power breathe ® K3.
According to Basso and Costa (2012), this assessment divided into two tests:
* Test incremental: starting with 10 centimeters of water, the volunteer is instructed to breathe normally for two minutes, thereafter a further minute, the next two minutes of exercise load will be increased, and so on until the volunteer fails to reach the predetermined pressure for three consecutive breaths or present dyspnea and / or fatigue. The largest load that is sustained for at least one minute will be considered the value of sustained maximal inspiratory pressure (PImáxS).
* Test constant: is conducted PImáxS to 80%, which is obtained in the previous test, and determined the time limit (Tlim) run 30 minutes. The stopping criteria are the same as the incremental test.
- Secondary Outcome Measures
Name Time Method EVALUATION OF LUNG VOLUMES AND CAPACITIES Preoperatively and on the high hostitalar - On day 1 and day 3 Spirometry was carried out according to the guidelines of the American Thoracic Society (ATS) and European Respiratory Society (ERS) (2005). Three types of maneuver were used in order to evaluate the lung volumes and flows: Slow Vital Capacity (SVC), Forced Vital Capacity (FVC) and Maximum Voluntary Ventilation (MVV). The maneuvers were carried out until three acceptable and reproducible curves were obtained, not exceeding more than eight attempts. The values extracted from each maneuver were selected according to Pereira (2002), and the predicted values calculated using the equation proposed by Pereira et al. (1992) for Brazilians.
