The choice of methods for assessing the metabolic status of a patient in the intensive care unit

Adequate nutritional support for critically ill patients has always been (and still remains) one of the main, complex and not fully resolved problems of modern intensive care, which, unfortunately, often remains without due attention. In everyday practice, in order to adequately correct nutritional deficiency, the resuscitator must, first of all, correctly assess the trophological status of the patient. Currently, there exists a large selection of nutrients and different methods for assessing metabolic status. The paper presents a critical analysis of existing methods for assessing the nutritional status and algorithms for the personalized choice of each of them in a specific clinical situation in critically ill patients.
