Sepsis is a syndrome of life-threatening organ dysfunction caused by a dysregulated host response to infection.Acute catabolic response in critically ill patients struck by sepsis, manifested by massive protein breakdown in a short time.This pathology frequently leads to prolonged hospitalization and mechanical ventilation, increased mortality, and reduced quality of survival.It is uncertainty whether sepsis patients in ICU can benefit from high protein intake combined with early exercise. Even though the combination has been shown to be beneficial in other populations.In the present study, the investigator will evaluate the effects of a combination of high protein targets combined with early rehabilitation in sepsis patients in ICU.
