The effect of intradialytic food intake on the urea reduction ratio and single-pool Kt/V values in patients followed-up at a hemodialysis center*

Materials and methods: The study was designed as a quasiexperiment. Twenty-five patients were enrolled in this study. The patients' mean age was 56.5 ± 13.0 years and median time on HD was 63 months. In the first stage of the study, patients were given a standard meal after the first hour of the treatment. The same study group underwent HD without intradialytic food intake 1 week later. Predialysis and postdialysis blood samples for measurement of blood urea nitrogen levels were drawn at the HD sessions with and without food intake. The URR and spKt/V values were calculated. Descriptive statistics, the paired samples t-test, repeated measures analysis of variance, and power analysis were used for the analysis of data.
