Critically ill patients experience metabolic changes that demand an adapted nutritional solution. Stressful medical events, such as surgery, trauma, infection and burn injury, can lead to hypermetabolism and net protein catabolism [1,2].
The enteral nutrition given to patients in this situation should aim to:
- Provide an adequate amount of specific dietary components to meet their increased and altered demands .
- Minimise the effect of catabolism associated with their metabolic response to stress .
