Abstract

Objective: The study was conducted to evaluate the status of blood magnesium and phosphorus disorders in patients undergoing continuous venovenous hemodialysis. Method: A Cross-sectional description study, data was collected on 29 patients undergoing CVVHDF at the Department of Intensive Care and Anti-Poisoning, Bach Mai Hospital from January 2025 to January 10, 2025. Results: A 29 patients study in which, the male/female ratio is 3/1, the average age is relatively high: 70.6 ± 11.0, the common age is 60 - 79 years old with 72.4%, the most common site of infection is the respiratory tract with 51.7%, the second is the digestive tract with 24.1%. More than half of the hospitalized patients were in shock with 55.1%, with 100% of patients receiving CVVHDF filtration. Magnesium concentration after dialysis (0.89±0.20 vs. 0.72±0.15 with p < 0.05), dialysis time, replacement fluid rate, dialysate rate, blood flow rate and comorbidity index were not correlated with the variation of Magnesium concentration after dialysis. Phosphorus concentration decreased after dialysis with 0.78 vs. 1.2 mmol/l, a significant difference with p < 0.05. Longer dialysis time had a higher decrease in Phosphorus concentration, other changes were not significant with p > 0.05. Conclusion: Magnesium concentration and Phosphorus concentration both tended to decrease after continuous venovenous hemodialysis, there was a correlation between the variation of Magnesium and Phosphorus concentration and dialysis time. Other factors such as gender and age did not affect the variation of Magnesium and Phosphorus concentration.
