Nutrition in Acute Renal Failure: Treatment Made Possible by Continuous Arteriovenous Hemofiltration (CAVH)
Continuous AV hemofiltration provides an exciting new approach to acute renal failure because of its simplicity and ability to handle large volume of fluids and electrolytes, but primarily because of the possibility of providing full nutritional support for renal failure patients. It is possible to feed patients using dialysis as a renal support system to be sure, but the hypermetabolic effects of hemodialysis, and other limitations of this technique have resulted in limiting protein and energy supply to critically ill patients with renal failure. With the advent of continuous arteriovenous hemofiltration (CAVH), full nutritional support is now possible, and several groups are just beginning to explore the effects of the feeding (and conversely the effects of our current treatment— starvation) in acute renal failure (1).
