This document discusses nutritional support for surgical patients. It begins by noting that malnutrition is common in 30% of surgical patients with GIT diseases and 60% of long-term hospital patients. Nutritional support aims to identify at-risk patients and ensure proper support. Assessment tools like MUST are described to screen patients. Enteral nutrition is preferred over parenteral when possible due to physiological advantages. Complications of both enteral and parenteral nutrition are outlined. The document emphasizes using enteral nutrition whenever the gut is available and reserving parenteral nutrition for clear contraindications to enteral feeding. A multidisciplinary team is ideal for optimizing nutritional care.
