ECW, and particularly its interstitial component, expands easily with malnutrition, sepsis, and trauma and after aggressive intravenous fluid therapy. In this scenario, hypoalbuminemia is usually the result of both an increased capillary escape rate due to leaky endothelium and increased distribution volume; this can be worsened by artificial intravenous nutrition with sodium, water, and glucose. Monitoring ECW is essential during TPN. Short-term changes in weight and serum albumin concentration are helpful to control ECW volume and prevent ECW expansion. Tetrapolar bioimpedance analysis is a promising technique for accurate bedside measurement of changes in body fluid compartments.

UI MeSH Term Description Entries
D009748 Nutrition Disorders Disorders caused by nutritional imbalance, either overnutrition or undernutrition. Nutritional Disorders,Nutrition Disorder,Nutritional Disorder
D009752 Nutritional Status State of the body in relation to the consumption and utilization of nutrients. Nutrition Status,Status, Nutrition,Status, Nutritional
D010289 Parenteral Nutrition, Total The delivery of nutrients for assimilation and utilization by a patient whose sole source of nutrients is via solutions administered intravenously, subcutaneously, or by some other non-alimentary route. The basic components of TPN solutions are protein hydrolysates or free amino acid mixtures, monosaccharides, and electrolytes. Components are selected for their ability to reverse catabolism, promote anabolism, and build structural proteins.
