[Deficiencies in trace elements during parenteral alimentation]

Abstract

During recent years, techniques of parenteral alimentation have seen the development of complications due to deficiencies in trace elements. The main deficiency states described involve iron, copper and zinc. In addition to these three trace elements, manganèse and cobalt are included in this study. The metabolism, physiological role, needs in parenteral alimentation and clinical and metabolic effects of possible deficiency are described for each of these elements.
