- Abstract
Introduction: Patients undergoing abdominal surgery have a risk of pulmonary complications in the postoperative period, such as: decreased respiratory activity, altered ventilation / perfusion ratio, and increased respiratory muscle work, increasing hospital morbidity and mortality. Objective: To evaluate the impact of positive expiratory pressure on lung function in postoperative patients of elective abdominal surgeries. Methods: Characterized as an exploratory study of the type randomized clinical trial, composed of 40 patients randomized into two groups, the intervention group was submitted to a protocol of positive expiratory pressure in the respiratory tract with final expiratory positive pressure of 10 cmH2O and ambulation for 150 meters and the control group underwent walking for 150 meters and guidelines on the importance of deep inspiration every two hours, being evaluated in the immediate postoperative period and at the time of hospital discharge. Results: A homogeneous pattern could be observed between the groups studied. Statistical significance was observed in the intra-group analysis in the variables peripheral oxygen saturation (p <0.0001) and peak expiratory flow (p = 0.009) vital forcing (p <0.0001). In the analysis between groups, a statistical difference was observed in peripheral oxygen saturation (p = 0.010) and peak expiratory flow (p = 0.012). Conclusion: We concluded that the use of positive expiratory pressure in the postoperative period of abdominal surgeries had a positive impact on peripheral oxygen saturation and peak expiratory flow, demonstrating a significant benefit in the ventilatory and diffusional process in the studied group.
