Validation of the nutritrauma concept for the detection of potential harmful effects of medical nutritional treatment in critically ill patients in real life.

Introduction: medical nutritional treatment (MNT) can be complex and may be associated with potential metabolic complications, which has been recently described as nutritrauma. Objective: the aim of our work is to describe whether the application of the nutritrauma concept in real life is feasible and useful to detect the metabolic complications associated with the prescription of MNT. Material and methods: in this descriptive, prospective study at a single center we enrolled 30 consecutive critically ill patients in a 14-bed medical-surgical intensive care unit. The nutritrauma strategy implementation was based in four "M" steps: Metabolic screening, MNT prescription, biochemical Monitoring, and nutritional Management. Results: we analyzed 28 patients (mean age, 69.7 ± 11.3 years; APACHE II, 18.1 ± 8.1; SOFA, 7.5 ± 3.7; Nutric Score, modified, 4.3 ± 2.01, and mean BMI, 27.2 ± 3.8). The main cause of admission was sepsis (46.4 %). Length of ICU stay was 20.6 ± 15.1 days; 39.3 % of subjects died during their ICU stay. Enteral nutrition (82.1 %) was more frequent than parenteral nutrition (17.9 %). During nutritional monitoring, 54 specific laboratory determinations were made. Hyperglycemia was the most frequent metabolic alteration (83.3 % of measurements). Electrolyte disturbances included hypocalcemia (50 %), hypophosphatemia (29.6 %) and hypokalemia (27.8 %). The most frequent lipid profile abnormalities were hypocholesterolemia (64.8 %) and hypertriglyceridemia (27.8 %). Furthermore, nutritional prescription was modified for 53.6 % of patients: increased protein dosage (25 %), increased calorie dosage (21.4 %) and change to organ-specific diet (17.8 %). Conclusions: in conclusion, the application of the nutritrauma approach facilitates detection of metabolic complications and an evaluation of the appropriate prescription of MNT.
