[Metabolic response to surgical stress and therapeutic perspectives].

Perioperative patients usually suffer from metabolic response. This metabolic state is usually the result of some blend of response to partial starvation and to injury or specific diseases. Metabolic response to starvation and acute injury is inbuilt response to ensure maximal survival with a limited food intake. Yet, progressive loss of body tissue may have lethal consequences. Enhanced recovery after surgery is an optimized strategy of perioperative treatment based on variations of meta bolic state. It can reduce damage and acute injury, as well as facilitating early recovery after major surgery.
