Abstract
Parenteral nutrition differs from enteral nutrition in two important aspects — other than the obvious one of delivery route. They are (1) the patient has little choice in the amount and type of nutrients he receives and (2) current formulations are biochemically devised diets. They have been designed to approximate to normal human dietary requirements as far as is compatible with limitations in the manufacturing process. Examples of the limitations are (1) the differential solubilities of amino acids seriously limit the amino-acid patterns that can be used; (2) the lipid emulsions used are pseudochylomicrons derived from semi-purified vegetable oils and (3) glucose is usually the major calorie source rather than the complex polysaccharides found in natural foodstuffs.
