Influence of Different Physical Therapy Resources Application After Abdominal Surgery
The aim of this study will be to investigate the effects of using physical therapy resources in the postoperative morbidly obese individuals undergoing gastroplasty.
It is believed that the application of these various features of physiotherapy after abdominal surgery may contribute differently in restoring lung function and prevention of pulmonary complications and can thus identify the resources that can contribute more effectively in post-operative bariatric surgery.

Detailed Description
The aim of this study will be to investigate the effects of using physical therapy resources in the postoperative morbidly obese individuals undergoing Roux-en-Y gastric by-pass with regard to: lung volumes and capacities, prevalence of atelectasis, thoracoabdominal mobility and evaluation of peak flow of cough, evaluated pre and post operative.
Individuals with BMI between 40 and 55 Kg/m², aged between 25 and 55 years, underwent the surgical procedure Roux-en-Y type gastric by-pass by laparotomy and normal preoperative pulmonary function will be included.
The volunteers will be divided into seven different groups, according to the treatment received during hospitalization after surgery:
G control: subjects treated with conventional physiotherapy according to the routine service of physiotherapy of the hospital; G Voldyne: subjects treated with incentive spirometry, Voldyne Model 5000® (Sherwood Medical, USA); G CPAP: subjects treated with "continuous positive airway pressure"; G EPAP: subjects treated with "expiratory positive airway pressure"; G IPPB: subjects treated with "intermittent positive pressure breathing"; G BIPAP: subjects treated with "bi-level positive airway pressure"; G BS: subjects treated with "breath stacking" (siliconized mask connected to a unidirectional valve allowing only inspiration).
The application of resources will be held twice a day in the immediate and in the first postoperative sessions in 6 sets of 15 reps or 30 continuous minutes, with an interval of 4 hours between sessions. The researcher will remain alongside the volunteers, following them and monitoring vital signs and respiratory comfort.

Arms and Interventions

Intervention / Treatment |
---|---|
No Intervention: Control
Individuals will be treated with conventional physiotherapy according to the routine service of physiotherapy of the hospital.
|
|
Experimental: Incentive spirometry (Voldyne®)
Individuals will be treated with incentive spirometry, Voldyne Model 5000® in the immediate and the first postoperative day, twice a day, in sessions of 6 sets of 15 repetitions each, with an interval of four hours between them.
|
The volume of incentive spirometry (Voldyne ®) is able to provide increased transpulmonary pressure gradient, which can prevent or reverse atelectasis.
|
Experimental: Continuous positive airway pressure
Individuals will be treated with flow generator(Whisperflow, Caradyne, Ireland)and valve PEEP type spring-loaded which remain 10 cmH2O, in the immediate and the first postoperative day, twice a day, in sessions 30 minutes each, with an interval of four hours between them.

The use of positive pressure airway seeking the prevention or treatment of hypoxic respiratory failure, improved arterial oxygenation, restoration or maintenance of lung volume reduction and atelectasis, decrease the work of breathing, decreased dyspnea index and increased residual volume.

Experimental: Expiratory Positive Airway Pressure
Subjects will be treated with oronasal mask affixed to the face, with the PEEP valve set at 10 cmH2O, in the immediate and the first postoperative day, twice a day, in sessions of 6 sets of 15 repetitions each, with an interval of four hours between them.

|
Experimental: Intermittent positive pressure breathing
Subjects will be treated with application of Müller Resuscitator (Engesp®) through a nozzle, using a pressure endotracheal 20-30 cmH2O, refering to 2-3 kgf/cm², adjusted throttle valve oxygen, according to the patient's comfort and the micronebulizer coupled only saline as the diluent.
The procedure will be performed in the immediate and the first postoperative day, twice a day, in sessions of 6 sets of 15 repetitions each, with an interval of four hours between them.

Experimental: Bi-level positive airway pressure
Individuals will be treated with positive pressure in the BiPAP mode (Bi-level positive airway pressure) in the immediate and the first postoperative day, twice a day, in sessions 30 minutes each, with an interval of four hours between them.

Experimental: Breath Stacking
Subjects will be treated with a siliconized mask connected to a unidirectional valve and adapted to the patient's face, allowing only the inspiration and the expiratory limb remains occluded, while the volunteer is instructed to perform successives inspiratory efforts, in the immediate and the first postoperative day, twice a day, in sessions of 6 sets of 15 repetitions each, with an interval of four hours between them.
|
The method allowed to obtain a maximum lung expansion with minimal patient compliance.

Time Frame |
---|---|---|
Pulmonary function
Time Frame: 2 days after surgery
|
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.

Prevalence of atelectasis
Time Frame: 2 days after surgery
|
The radiological report on the inspiration radiography, issued by the hospital radiologist, was used to analyze the presence of atelectasis.
|
2 days after surgery
|
Thoracoabdominal mobility
Time Frame: 2 days after surgery
|
The measurement of thoracoabdominal mobility was performed by using a tape scaled in centimeters.
In the standing position, the measurements were made at levels axillary, xiphoid and abdominal during rest, and at maximal inspiration and maximal expiration.
At each level, the measurements were performed three times.
It computed the highest value of inspiration and the lowest of expiration.
The absolute difference between these values was considered the thoracoabdominal mobility.

2 days after surgery
|
Peak cough flow
Time Frame: 2 days after surgery
|
The peak flow measured during a cough maneuver will be measured by the equipment Peak Flow ®.
For this, the volunteer will be instructed to place the mouthpiece between the lips of the equipment and play a cough with nostrils occluded nose clip.
The maneuver should be repeated three times and the best preoperative measures will be compared to the best postoperative measurement.
