Vitamin and trace element administration during continuous renal replacement therapy (CRRT) in the intensive care unit (ICU)

Administration of nutrients during critical illness is depicted in current guidelines, e.g. in the guidelines of the American Society for Parenteral and Enteral Nutrition (ASPEN) [1] or in the European Society for clinical Nutrition and Metabolism (ESPEN) [2]. Special recommendations for critically ill children requiring continuous renal replacement therapy (CRRT) also exist [3]. The prescription of micronutrients like vitamins and trace elements is of moderate evidence especially for renal dysfunction and during CRRT and solid data of adequate micronutrient administration during critical illness are lacking. The dynamic of critical illness should be kept in mind which can have a relevant impact for vitamin or trace element requirement.
