[Criteria for pharmacologic quality in artificial nutritional support applied in Peru].

This is a report on the metabolic consequences derived from widely using a parenteral nutrition scheme in Peru. That scheme was in disagreement with internationally accepted principles. Its lack of capacity to achieve anabolism is demonstrated. Enteral and parenteral nutrition schemes that clearly achieve anabolism are shown as well as the notorious contrast with the parenteral nutrition scheme referred to previously. These facts set up the basis of the Formulary of Nutritional Support Units of Instituto Peruano de Seguridad Social.
