BACKGROUND: Testing metabolic effects of a novel calcium-free, magnesium, phosphate and lactate containing solution (Lactocitrate) in combination with citrate anticoagulation. METHODS: Patients on CRRT (2,000 ml/h, blood flow (Qb) 100 ml/min, trisodium citrate (4% TSC)) with arterial lactate <3 mmol/l were included. At start, bicarbonate-buffered fluid was changed to Lactocitrate and the substitution of magnesium and phosphorus ceased. At 9 h the Qb was increased to 150 ml/min. At 18 h the CRRT dosage was increased to 3,000 ml/h. RESULTS: In 22 CVVHDF patients and another 23 on CVVH the pH, aHCO3 and Na (all p > 0.05) showed no significant changes regardless of the increased dosage of 4% TSC at 9 h (p < 0.001). Mgtot and phosphorus stabilised within normal range. Arterial lactate increased to 1.9 (1.6-2.6) mmol/l at 3,000 ml/h, p < 0.001). Citrate- and lactate-related energetic gains were up to 74 (61-86) kJ/h. CONCLUSIONS: The fluid performed well within ordinary CRRT dosage and Qb up to 150 ml/min. Lactate levels mildly increased and no magnesium and phosphorus replenishments were necessary.
