Abstract
Objective: To analyze the effects of high-flux hemodialysis (HFHD) on calcium and phosphorus metabolism and nutritional indicators in patients with chronic kidney disease (CKD). Methods: A total of 86 CKD patients diagnosed in our hospital’s Nephrology Department between January 2024 and December 2025 and undergoing HFHD were enrolled. Using a random number table, all patients were divided into a control group (n = 43, receiving conventional hemodialysis) and a study group (n = 43, receiving HFHD). SPSS 26.0 statistical software was used to compare calcium-phosphorus metabolism and nutritional indicators between the two groups. Results: After 6 months of treatment, the PTH level in the study group was significantly lower than that in the control group, while serum calcium and phosphorus levels were significantly higher (p < 0.05). The Alb and Hb levels in the study group were higher than those in the control group, but the difference was not statistically significant (p > 0.05). Conclusion: HFHD maintains calcium-phosphorus metabolism balance in CKD patients while significantly improving nutritional indicators.
