Volumetric control of continuous haemodialysis in multiple organ failure.

A system for precise volumetric control of continuous haemodialysis and its use in providing renal replacement treatment in the intensive care unit to 10 children with multiple organ failure are described. The system, termed slow efficient dialysis, provided effective clearance of urea, creatinine, potassium, and phosphate. It provided precise control of the volume of ultrafiltrate removed in a prospective manner ('dial up' fluid balance) to reduce haemodynamic instability and fluid management problems. The ease of use of this system for intensive care nurses meant that the system ran without the assistance of a second intensive care or renal nurse.
