Summary

Obesity, due to excess fat in the thoracoabdominal region, can promote changes in respiratory function and lung function, leading to reduction in lung volume and capacity. Such dysfunctions are worsen after bariatric surgery to be associated with factors inherent to this procedure. The objective of this study was to evaluate and compare the effects of the application of bilevel positive airway pressure and exercises with inspiratory pressure with linear load in thoracoabdominal mobility, pulmonary function, inspiratory muscle strength, respiratory muscle strength and prevalence of pulmonary complications after bariatric surgery.

Detailed description

This is a clinical trial, randomized, blinded, in which 60 volunteers, after evaluation preoperatively, consisting of: cirtometry to measure thoracoabdominal mobility, spirometry for measures of lung function, nasal inspiratory pressure to inspiratory muscle strength and endurance incremental test for evaluation of respiratory muscle strength, were randomized and allocated into three groups, with 20 volunteers each. The interventions were performed in the immediate postoperative period and the first day after surgery. The first group, called the control group received care by Conventional Respiratory Physiotherapy (CRP), consisting of breathing exercises, incentive spirometer and ambulation. The second group, called Positive Pressure Group received two-level positive airway pressure for one hour, addition of CRP. The third group, called Load Inspiratory Group held exercises with inspiratory pressure with linear load, linked also to the CRP. Treatments were applied twice in the immediate postoperative period and shortly after returning to the ward and after 4 hours of the initial treatment and three times a day on the first day after surgery. On discharge, the second day after surgery, the volunteers performed chest x-ray and underwent the same evaluations performed preoperatively.

Conditions

• Inadequate or Impaired Respiratory Function

Interventions

Type	Name	Description
DEVICE	Bilevel positive airway pressure	The use of positive airway pressure airway seeking in 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
DEVICE	PowerBreathe	Exercises with inspiratory load has the aim to trainning inspiratory muscle in strength and endurance, thus, could help to prevent postoperative complications.
PROCEDURE	Conventional Respiratory Physiotherapy (CRP)	CRP consisted of diaphragmatic respiratory exercises, deep inhalation exercises, inhalations fragmented two to three times and respiratory exercises associated with shoulder flexion movements and extension of the upper limbs. One series of 10 repetitions was carried out for each exercise. Walking sessions and preventive exercises for deep vein thrombosis were carried out
