Efeitos do treinamento muscular respiratório na força muscular respiratória e função pulmonar em doentes renais crônicos dialíticos

Abstract

Respiratory muscle training (RMT) has been inserted in the integral care for patients with chronic renal disease (CKD) who were submitted to hemodialysis (HD) aiming to improve their pulmonary and physical condition. The study evaluated the RMT effects on respiratory muscle strength (RMS) and lung function (LF) in individuals with CKD submitted to HD. A pilot and longitudinal study was performed with 16 patients with CKD submitted to HD. During the experiment, were measured: Maximum inspiratory pressure (MIP), maximal expiratory pressure (MEP), forced vital capacity (FVC) and forced expiratory volume in the first second (FEV1). In a period of 24 attendances, TMR with ThreshouldPEP was applied 2 during the HD session. The first 12 sessions were performed with initial 15cm / H2O loading, divided in 15min for inspiratory musculature and 15min for expiratory musculature. In the last 12 sessions, a 20cm / H2O loading was parted in 20 minutes for each type of musculature during 3 times weekly. In order to compare variables before and after the experiments, the "T" test Paired study was utilized, with p≤0.05; through SPSS, version 15.0. After training, a significant increase in FMR-MIP variables was noticed: (72.56 ± 21.19cm / H2O versus 105.24 ± 23.60cm / H2O, p = 0.016); MEP: (75.94 ± 19.28cm / H 2 O versus 104.38 ± 19.56cm / H 2 O; p = 0.001). Regarding PF, it showed a significant increase in FVC: (3.35 ± 1.10 versus 3.52 ± 1.05, p = 0.001); and FEV1: (2.49 ± 0.77 versus 2.81 ± 0.84, p = 0.001). For RMT can be inserted to treat chronic renal patients in HD, improving respiratory system function and alleviating respiratory compromise, a common issue in this population.
