OBJECTIVE. To describe the use of an automatic fluid control system, Equaline, during high flux continuous hemofiltration. DESIGN. Prospective descriptive study. SETTING. General intensive care unit in a general hospital. PATIENTS. 15 consecutive patients suffering from septic shock, hypercatabolic with acute renal failure. INTERVENTION. Pump driven continuous veno-venous hemofiltration (PDCVVH) with high flux was performed. All pts were intubated, under mechanical ventilation and treated with vasoactive agents for hemodynamic instability. Fluid balance was achieved with an automatic fluid control system, Equaline, on daily basis according to clinical needs. MEASURES. Length of treatment, daily amount of ultrafiltrate and urea removal, urea and creatinine blood level before and after the treatment were registered. RESULTS. Age was 59.1 years, SAPS 17.2. Patients were treated for an average period of 9 days obtaining a daily ultrafiltrate production of 21.4 L. In all pts, though the high catabolism (daily nitrogen production > 30 g), there was a significant decrease of urea and creatinine concentration. CONCLUSION. Equaline system was able to maintain intravascular volume in the face of high ultrafiltration rate avoiding clinically important discrepancies between ultrafiltrate formation and fluid replacement. We conclude that PDCVVH management is greatly improved with use of such servo-controlled feedback system.
