title: Assessing the efficacy of nutritional support.
abstract: This review outlines the conventional methods of assessing nutritional status and their limitations in the presence of acute trauma and sepsis. It also discusses the problems of attempting to improve or at least maintain nutritional status in the presence of an inflammatory stimulus. Most of the conventional markers of nutritional status are altered in trauma and sepsis with decreases in plasma protein concentrations and muscle strength, an apparent depression of immune function and an increase in extracellular fluid volume. It also appears to be impossible to improve nutritional status in the presence of a severe inflammatory stimulus, and the most one can hope for is to attenuate the rate of decline. The evidence for these observations is discussed.
