The effect of fluid education given to hemodialysis patients on interdialytic fluid intake and blood pressure

The research evaluated the effect of nutrition and fluid restriction training on interdialytic fluid intake and intradialytic hypotension in hemodialysis patients. The study sample, conducted with an experimental design, consisted of 71 patients (36 experimental and 35 control) who received dialysis treatment in a private dialysis centre affiliated with the Istanbul Provincial Health Directorate. Fluid Control Scale in Hemodialysis Patients (HHSÖ), Blood Pressure Control Form, Bioimpedance Analysis, Bioimpedance Analysis Compliance Form, Things to Consider Before Bioimpedance Analysis, and Nutrition Booklet for Dialysis Patients were used to collect the data. Parametric methods were used to analyze the data. Differences between the proportions of categorical variables in independent groups were analyzed with Chi-Square and Fisher's exact tests. The t-test was used to compare quantitative continuous data between two independent groups. A dependent group t-test was used to compare intra-group measurements. After randomization of the experimental and control groups, both groups were measured with the BCM (Fresenius Medical Care Body Composition Monitor) device. The experimental group was given face-to-face fluid restriction training in line with the Nutrition Booklet for Dialysis Patients. At the end of the second month, BCM was measured again in both groups. During the follow-up of the experimental group, training was repeated according to the needs of the patients. Biochemical values of the experimental and control groups were monitored every month throughout the study. As a result of the research, the control group's average age and status of receiving fluid restriction training from a dietitian were high (p<0.05), the experimental group's potassium measurement value was low, the HHSS total score, knowledge, behaviour and attitude subscale scores were high (p<0.05). It was found to be significant. There was no significant difference in intradialytic hypotension in the experimental and control groups. As a result, providing only fluid restriction training to hemodialysis patients does not reduce interdialytic fluid intake and intradialytic hypotension.
