[Nutritional support in sepsis].
Although it is considered that metabolic and nutritional support must be part of the management of septic patients, it has not been conclusively shown that nutritional support will improve survival or complications from sepsis. Specific data on this issue are scarce since there are few studies that have investigated specialized nutritional support in septic patients. Thus, most of the recommendations are based on outcomes obtained in severely ill patients with different pathologies. It is assumed that nutritional support should be carried out through the enteral route whenever possible, as in other critically ill patients. The energetic waste in these patients is highly variable, although in general terms the hypermetabolic situation may be classified as moderate. An adjustment factor of 1.25-1.30 is recommended for the Harris-Benedict's equation to calculate the caloric intake. Septic patients should receive a hyperproteic intake. The amount of glucose administered should not exceed 70% of non-protein calories, and lipids intake should not exceed 40%. With regards to micronutrients, it is recommended to increase the supply of those with antioxidant properties (vitamin E, carotenes, vitamin C, selenium). There are data to consider that the use of diets enriched with pharmaco-nutrients (both with parenteral and enteral routes) may be beneficial in septic patients, although there is some controversy when interpreting the outcomes.
