Malnutrition is defined by an energy supply deficit, protein, macro-molecules or
micro-nutrients, resulting from an imbalance between nutrient intakes and metabolic needs of
the body. It concerns 40 to 60% of patients upon entry into resuscitation and influences
their prognosis. Studies over the past decade have shown that nutritional deficiency
increases the morbidity and mortality in intensive care.
Several clinical and biological parameters were evaluated as markers of malnutrition,
including the ratio of urea / urine creatinine.
The report would identify patients in a state of malnutrition, to optimize their nutritional
This setting is easy to obtain in all patients by simple urine collection unlike other
clinical and biological criteria of resuscitation malnutrition assessment.
This ratio of urea / urien creatinine would optimize energy intake of critically ill
patients, for which nutritional management methods are widely debated.
