[Acute respiratory distress syndrome. Nutritional and metabolic support].
The application of artificial nutritional treatment in critical patients, nowadays is a completely accepted fact. To a large degree this is due to the advances made in the understanding of the metabolic response shown by patients against a severe and persistent aggression. One of the entities which presents the highest mortality in critical patients, is the Acute Respiratory Distress Syndrome (ARDS), which one understands as the pulmonary response to different types of aggression. To understand the metabolic implications in the face of the development of this syndrome, would permit a better understanding of the need to treat these patients and to establish the nutritional standards which are most adequate to each different metabolic alteration. It would not only be important to understand the most effective method for calculating the caloric needs of these patients, but we shall also have to deepen our understanding of possible harmful effects of the different substrates, which undoubtedly could condition morbidity. This is why in this review we focus on the intimate pulmonary mechanism, both in healthy conditions as in those of disease, in order to extrapolate conclusions which are potentially applicable to patients suffering from an acute pulmonary lesion, as those suffering from ARDS: A main role shall be played the assessment of the administration of macronutrients in the form carbohydrates, lipids, and amino acid particles, due to the implications which each of these may have on the lesioned lung and its ventilatory capacity.
