Abstract

Introduction: Pulmonary complications in postoperative of cardiac surgery may be related to respiratory muscle weakness. Objective: To assess whether the low values for maximal respiratory pressures can be predictors of postoperative pulmonary complication and or longer hospital stay in patients undergoing cardiac surgery. Methods: Fourteen patients undergoing cardiac surgery were evaluated in the preoperative and divided into two groups, A (patients with maximal respiratory pressures < 75% of the predicted values) and B (patients with respiratory muscle strength ≥ 75% of the predicted values). Results: Group B showed a lower number of hospital stay (p = 0.03). The incidence of pulmonary complications was 20% in group A. Conclusion: It was not possible to conclude, in the population studied, whether respiratory muscle strength was predictor of postoperative complication. However, patients with respiratory muscle weakness diagnosed previously to heart surgery tended to stay in hospital for a longer period of time.
