Early mobilization versus positive pressure in the postoperative period of elective abdominal surgery: A randomized clinical trial

Abdominal surgery causes pathophysiological transformations that can be characterized by recurrent episodes of post-surgical complications ranging from pulmonary complications to complications inherent to surgical incision. Pulmonary complications are the main causes of postoperative morbidity and mortality and can be minimized and/or avoided through physiotherapy. This study aims to verify whether there is superiority between early mobilizations versus positive pressure continues in the airways on clinical variables and pulmonary function in postoperative patients of elective abdominal surgery. The study is a subproject, quantitative, analytical, exploratory of the randomized clinical trial type. The study sample consists of 20 volunteer individuals who were subdivided into two groups, the patients were evaluated for maximum inspiratory strength, maximum expiratory and peripheral muscle strength, then underwent ambulation or positive pressure, and when discharged the patient was reevaluated. Early mobilization was superior to positive pressure since maximum inspiratory pressure had significant statistical differences only for in the ambulation group (p=0.007), maximum expiratory pressure and peripheral muscle strength no static differences were found (p = 0.910 and p = 0.853, respectively).
