Overview
Brief Summary
The purpose of this study is to assess the effect of post-operative inspiratory muscle training on muscle strength and endurance in patients with obesity submitted to gastroplasty.
Detailed Description
Gastroplasties, like other major abdominal surgeries, induce mechanical changes in the lungs and decreases of the respiratory muscle strength in the post-operative periods. Depending on the occurrence of pre-existing disturbs, obese patients may exhibit severe declines of respiratory function after these surgeries. Post-operative respiratory physiotherapy is a valuable intervention, involving a set of techniques aimed to expand pulmonary volumes and to improve arterial oxygenation, leading to decreases on the development of atelectasis and pneumonias. It induces faster recovery of respiratory function and reduction of lung complications, what may be particularly important in high-risk patients like over-weighted subjects. There are scanty data about the role of respiratory muscle training in the post-operative period. This is particularly true regarding inspiratory muscle training of obese patients submitted to gastroplasties.

Outcomes
Primary Outcomes
Maximum static respiratory pressures
Time Frame: post-operative days 2, 7, 14, and 30
This measurement was made at mouth level by using a properly calibrated manovacuometer (GERAR ®, São Paulo, Brazil), with graduation ranging from 0 to ± 300 cmH2O, connected to a rigid plastic tube.
Inspiratory muscular endurance test
Time Frame: post-operative days 2, 7, 14, and 30.
This measurement was performed by using the Threshold® IMT device (Health Scan Products, USA), at 80% maximal inspiratory pressure, in sitting position.
Spirometric measurements
Time Frame: post-operative days 2, 7, 14, and 30.
Spirometry was performed according to norms of the American Thoracic Society (ATS) (1994)19 by using a previously calibrated spirometer (Respiradyne II Plus®, Sherwood Medical, St. Louis, USA).
Secondary Outcomes
- Maximum static respiratory pressures(post-operative days 2, 7, 14, and 30)
- Inspiratory muscular endurance test(post-operative days 2, 7, 14, and 30)
- Spirometric measurements(post-operative days 2, 7, 14, and 30.)
