Parenteral Nutrition in Critical Illness
In many patients with critical illness the standard approach to parenteral alimentation is not possible, for the limits of water, sugar and electrolyte tolerance are dependent on the underlying condition. Furthermore, the growth process in an unstressed infant allows incorporation of potassium, phosphate, water and nitrogen into newly formed cells so that smaller solute and water loads are presented for excretion. It is unreasonable to expect average anabolic requirement to apply in critical illness where growth is not occurring.
