P1477EFFECT OF INTRADIALYTIC EXERCISE IN A MEXICAN MAINTENANCE HEMODIALYSIS POPULATION

Abstract

Abstract Background and Aims The use of intradialytic exercise has been associated with improved clearance, oxygen consumption, quality of life, and physical performance. The aim of this study was to describe the association between of intradialytic exercise and some outcomes in a Mexican maintenance hemodialysis (HD) population. Method Observational comparative study that included 84 maintenance HD patients from one HD center in Mexico City. The population was grouped according to the intradialytic exercise local record. The aerobic intradialytic exercise protocol includes cycling for 30-45 min during the first 2 hours of the HD according to each patient’s ability. A retrospective registry of clinical and biochemical parameters was realized. Also, the hemodynamic parameters of the last six HD sessions for each patient was included. Data analysis was carried out through descriptive and inferential statistics. Results Of the total population, 45.2% were men (n= 38) and the mean age was 53.6 + 17 years. Fifty one percent (n= 43) had diabetes mellitus (DM), which resulted more prevalent in the subgroup of patients without intradialytic exercise (p=0.03) No differences between groups were present in age, history of previous peritoneal dialysis or kidney transplant. The rest of baseline data are shown in Table 1. The subgroup of patients who underwent intradialytic exercise presented higher levels of serum albumin (p=0.03) and lower levels of parathormone (p=0.03). A total of 504 HD sessions were analysed and intradialytic exercise was performed in 64.3% (n=324). Patients in the intradialytic exercise program presented high levels of systolic and diastolic blood pressure (graphic 1). Intradialytic hypotension occurred in 5.2% (n=26) and no differences are shown between groups (p=0.78). No mayor side effects were reported. Conclusion The intradialytic exercise could improve nutritional and bone-mineral status markers. The patients in an intradialytic exercise program presented higher levels of blood pressure.
