Impact of flow incentive spirometry on the ventilatory muscle function of patients in the elevative abdominal surgery post-operative

The aim of this study was to demonstrate the effectiveness of inspiratory flow incentive on pulmonary function and peripheral muscle strength in postoperative patients after elective abdominal surgery. Methods: Data collection was performed in the immediate postoperative period, with maximal inspiratory (MIP) and expiratory (MEP) pressures using digital manovacuometry. as well as the dynamometer measurement. Results: Fifty patients were evaluated, with a mean age of 39.92 ± 15.12 years. Regarding respiratory muscle strength, it can be inferred that both the mean MIP undergoes a positive change (initial 40.96 ± 31.49 and final 52.10 ± 37.44) with (p ≤ 0.001) and PeMax the mean increase after the procedure (initial of 33.16 ± 22.56 and final of 38.22 ± 25.95), with a statistically significant difference between the means of reassessment and evaluation (p = 0.039). It was possible to infer that although the sample presented initial average of 24.76 ± 10.45 and final of 24.99 ± 13.48, resulting in an increase in dynamometry, this difference has no significant statistical correlation (p = 0.163). Conclusion: There was an increase in MIP and MEP after intervention with the flow incentive inspirometer, but no increase in peripheral muscle strength.
