Evaluation of respiratory muscle strength and pulmonary function of patients with chronic kidney disease submitted to hemodialysis

Abstract

Objective: To assess respiratory muscle strength (RMS) and lung function (PF) in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). Methods: Cross-sectional study with 41 participants. Maximum inspiratory and expiratory pressures (MIP; MEP), Forced Vital Capacity (FVC) and forced expiratory volume in the first second (FEV1) were checked. Results: There is no significant difference between men and women in relation to the percentage of the predicted achieved for MIP, but there is in relation to MEP (p = 0.082; p = 0.003). As for PF, it was found that there is a significant difference between men and women, for both variables FVC and FEV1 (p = 0.034 and p = 0.024). Conclusion: Regarding RMS, patients with chronic kidney disease on hemodialysis have respiratory muscle weakness, and when compared by gender, men had reduced inspiratory muscle strength compared to predict. As for PF, women have values below normal standards compared to men.
