Abstract

Dietary salt intake is the primary reason of weight gain between two dialysis for the hemodialysed patient population. Osmotic polydipsia which develops secondarily to salt intake, is accompanied by fluid intake. Increase in blood pressure secondarily to hypervolemia, is associated with cardiovascular mortality. Thus it is important to know the amount of dietary salt intake of hemodialysis patients. In this study, it is intended to calculate amount of sodium intake in hemodialysis patients by means of nutrition survey method. Furthermore, this calculated sodium intake was compared with the sodium intake which was calculated by conventional methods. For this purpose 20 anuric patients, who take place in chronic hemodialysis program and undergo hemodialysis three times a week, were included in the study. The patients with a comorbidity which may affect the serum sodium level, were excluded from the study. Patients? dietary intake from the exit to the following entry of dialysis was self-written to nutrition survey form. Body weights of patients were measured and their blood samples were taken to measure serum sodium at the exit of and before the following entry into the dialysis. Sodium amount which is obtained by patient dietary survey method is called as ?dietary sodium?, while sodium amount which is calculated by serum sodium samples and total body fluid at entry and exit of dialysis is called as ?calculated sodium?. At the end of the study, it was found that dietary sodium amount is higher than the calculated sodium amount for hemodialysis patients, however this difference was not statistically significant (p=0.804). It was observed in correlation analysis that there isn?t a correlation between dietary sodium and calculated sodium and between dietary sodium and weight changes. In addition, it was found that there is a strong correlation between calculated sodium and weight changes. In our study, poor correlation of dietary sodium with calculated sodium and weight changes can be explained by non-osmotic sodium. However, further studies with larger patient populations are required.
