Optimizing Nutritional Status of Patients Prior to Major Surgical Intervention

Abstract

In patients undergoing elective cardiovascular and thoracic surgery, malnutrition and the deterioration of nutritional status are associated with negative outcomes. Recognition of the contributory factors and the complications stemming from surgical stress is important for the prevention and management of these patients. We have reviewed the literature available and focused on the nutritional and metabolic aspects affecting surgical patients, with emphasis on the recommendations of enhanced recovery protocols. The implementation of enhanced recovery protocols and nutritional support guidelines focusing on the surgical patient as part of a multidisciplinary approach would improve the nutritional status of surgical patients at risk for negative outcomes.
