Nutritional Support in Critically Ill Trauma Patients

Enteral nutrition should be initiated within 24 to 48 hours of injury, starting at a trophic rate and increasing to goal rate after hemodynamic stability is achieved. The modified Nutritional Risk in the Critically Ill score can help identify patients who will benefit most from aggressive and early nutritional intervention. In the first week of critical illness , the patient should receive only 70% to 80% of estimated calories and protein should be targeted to 1.5 to 2 g/kg. Parenteral nutrition can be provided safely without increased adverse events. Peri-operative (and intra-operative) feeding has been shown to be safe in selected patients.
