Electrolytes-Enriched Hemodiafiltration Solutions for Continuous Renal Replacement Therapy in Acute Kidney Injury: A Crossover Study.

ABSTRACT

AIMS: To evaluate the capability of an electrolytes-enriched solution to prevent metabolic disorders during continuous veno-venous hemodiafiltration (CVVHDF). METHODS: Serum biochemistry and clinical tolerance were compared during CVVHDF treatments with an electrolyte-enriched (Phoxilium) or standard solutions in 10 acute renal failure patients. RESULTS: As compared to standard fluids, serum potassium and phosphate levels were maintained in the normal range with Phoxilium without any supplementation but total serum calcium levels were significantly lower. Bicarbonatemia was slightly higher (24-26 vs. 21.5-24.5 mmol/l, p < 0.05) with conventional solutions and was associated with a significant increased level of pH (>7.44). Despite the absence of glucose in the Phoxilium solution, blood glucose levels and glucose supplementation were similar between treatments. Clinical tolerance and efficiency of CVVHDF sessions were comparable. CONCLUSION: Phoxilium effectively prevented hypophosphatemia and hypokalemia during CVVHDF. It was, however, associated with a slight metabolic acidosis and hypocalcemia compared with conventional solutions.
