Abstract

Introduction: Respiratory techniques are fundamental in the postoperative period of cardiac surgery in order to reduce postoperative complications. Objectives: The aim of this study was to compare two techniques of respiratory physiotherapy in mucociliary clearance, respiratory muscle strength and airway obstruction after cardiac surgery. Methods: Thirty-two patients undergoing coronary artery bypass grafting were assigned to the intermittent positive pressure group or to the deep breathing exercise group. The evaluations were composed of: respiratory muscle strength (maximal expiratory pressure and maximal inspiratory pressure), peak respiratory flow and mucociliary clearance (through the saccharine transit time test, expressed in minutes); And performed in three moments: preoperative and postoperative before and after the application of the techniques. Results: In the analysis of mucociliary transport, respiratory muscle strength and peak expiratory flow, the comparison between the moments before and after the application of the techniques did not present significant differences (mucociliary transport: p = 0.3844, Pimax p = 0.2244; = 0.4968; Peak flow p = 0.8383). In the individual analyzes of each group, significant differences were observed in the variables of respiratory muscle strength and peak expiratory flow (p <0.0001). Conclusion: There were no significant differences between the techniques, but were efficient in mucociliary clearance, muscle strength and peak expiratory flow when evaluated separately.
