Perioperative Supplementation With Immunonutrition and Its Impact on Surgical Outcome and Pain in Oral Cavity or Mandibular Tumours

Enhanced Recovery after Surgery (ERAS). A series of components that combine to minimize stress and to facilitate the return of function have been described: these include preoperative preparation and medication, fluid balance, anesthesia and postoperative analgesia, pre- and postoperative nutrition, and mobilization.

Nutrition therapy is the provision of nutrition or nutrients either orally (regular diet, therapeutic diet, e.g. fortified food, oral nutritional supplements) or via enteral nutrition (EN) or parenteral nutrition (PN) to prevent or treat malnutrition.

Head and neck cancer surgery usually means surgery to treat cancer of the mouth, throat or larynx . The surgery is complicated and people often experience problems such as wound infections and wound breakdown, as well as infections such as pneumonia.

The use of a nutritional supplement enriched with Omega 3 fatty acids is associated with a greater preoperative weight loss, reduced postoperative pain and decreased postoperative levels of C reactive protein in patients undergoing Roux-en-Y gastric bypass.
