Abstract    Parenteral nutrition is associated with mechanical, metabolic and infectious complications. Infections are not uncommon and are associated with refractory hyperglycemia caused by stress response. Hyperglycemia is one of the metabolism characteristics in critically ill patients. Patents performed enteral nutrition treatment have a relative low incidence of metabolic and infectious complications. One of the most important infectious complications is aspiration pneumonia. Risk factors that significantly correlated with pneumonia were low bed backrest, vomiting, gastric feedings, a Glasgow Coma Scale score <9, gastroesophageal reflux disease, high sedation level and the use of paralytic agents. Gastrointestinal complications are very common in enterally fed patients. The reasons causing gastrointestinal complications are complex, and medication should be based on different reasons.
