Brief Summary
Post stroke pneumonia (PSP) is one of the common early complications of stroke. Post-stroke infections, in general, are associated with less favorable neurologic outcomes. Aspiration is one of the most feared complications of enteral nutrition and can lead to the occurrence of pneumonia. Severe stroke patients are at high risk for aspiration due to some factors such as the reduced level of consciousness, inability to protect the airway and so on. The purpose of this study is to explore the ideal nutrition support strategy for patient with acute severe stroke to help reduce the incidence of PSP and improve the prognosis.

Study Arms (2)
Full enteral feeding
ACTIVE COMPARATORPatients will receive full enteral feeding through nasogastric tube or nasointestinal tube.
Trophic enteral feeding combined with supplemental parenteral nutrition
EXPERIMENTALPatients will receive trophic enteral feeding combined with supplemental parenteral feeding.
Interventions
The caloric goal of the first day is one-third of caloric requirements, the second day is half of caloric requirements, the third day is 70-100% and sustained for 1 week. Patients will receive the trophic enteral feeding with a caloric target of 500kcal/d (20-35ml/h), and the remaining calories are supplemented by parenteral nutrition. Protein requirements are calculated at 1.2 to 1.5 g per kilogram of body weight per day.
The caloric goal of the first day is one-third of caloric requirements, the second day is half of caloric requirements, the third day is 70-100% and sustained for 1 week. Protein requirements are calculated at 1.2 to 1.5 g per kilogram of body weight per day. Enteral nutrition is given through nasogastric tube or nasointestinal tube.
