Trace Elements in Critically Ill Patients
Mohamed Abdraboh Abdel-aziz;
Abstract
Nutritional support of intensive care patients is important, and aims to prevent the development of malnutrition. Malnutrition in these patients is under-recognized and under-treated problem. It has been shown to be strongly linked to increased length of stay in hospital, morbidity and mortality.
A careful balance of macronutrients (protein, lipid and carbohydrate) provides the energy requirements whilst micronutrients (vitamins, electrolytes and trace elements) are required in small amounts to maintain health but not to provide energy.
Nutritional assessment in critically ill patients may be difficult however many methods as anthropometric measurements, biochemical tests (including albumin and other plasma protein levels) and subjective global assessment shown to be reproducible and correlates with mortality in a variety of cases.
Nutritional delivery may be enteral or parentral. Each has its indications, advantages and complications. The ideal route and timing differs according to each case.
Trace elements as a component of nutrition may be subdivided into essential, possibly essential and nonessential.
Because of the presence of trace elements in very small amounts in human body (0.01% or less of the total body weight) and the absence
