Parenteral Nutrition in the Critically Ill Patient

Abstract

A 67-year-old woman with type 2 diabetes mellitus undergoes extensive bowel resection for mesenteric ischemia. Tube feedings are associated with adverse effects, and central venous parenteral nutrition is recommended. The appropriate use of parenteral nutrition is controversial, though in selected circumstances it can be beneficial. Control of hyperglycemia is essential. Overfeeding and the refeeding syndrome are potential adverse effects.
