AbstractGut malnutrition in patients with persistent hypermetabolism is hypothesized to be an important factor in postseptic multiple organ failure syndrome (MOFS). The hypothesis was made that enteral nutrition (EN) started at the onset of hypermetabolism could reduce the incidence of MOFS. Sixty-six patients with persistent hypermetabolism 4 to 6 days after onset of sepsis were prospectively randomized to receive either parenteral nutrition (PN) or enteral nutrition (EN) at 1.5 gm protein/kg/day and 30 nonprotein calories/kg/day; the EN and TPN were of the same composition. There was no reduction in either the incidence of MOFS or mortality attributable to the route of nutrition administration. The PN group tended to have better visceral protein support; the EN group had more gut complications. When analyzed, the type of formula given did have an effect on the nutritional outcome but not on the mortality rate. A formula with a nonprotein-calorie-to-nitrogen ratio of 100:1 was associated with more nitrogen retention, higher levels of visceral proteins, and better gut tolerance. The route of nutrition administration does not seem to affect the incidence of postseptic MOFS or mortality when hypermetabolism is already present and when commercially available nutritional formulas are used. The relationships among the route of nutrition, the type of enteral formula, and the disease process of hypermetabolism and MOFS appear to be complex and require much more investigation before the role of the gut and enteral nutrition can be defined.
