A. Nutrition Assessment A nutrition risk indicator nutrition therapy • Nutritional risk screening [NRS 2002] • NUTRIC score • All patients admitted to the ICU for whom volitional intake is anticipated to be insufficient. • High nutrition risk identifies those patients most likely to benefit from early EN therapy. Tools, Components, Surrogate markers Nutrition assessment include: • evaluation of comorbid conditions • function of the gastrointestinal (GI) tract • and risk of aspiration • We suggest not using traditional nutrition ...
Background Feeding protocols are considered to be an effective strategy to maximize the benefits and minimize the risks of enteral nutrition in critically ill patients. Components of feeding protocols may include orders for Early initiation of enteral nutrition Use of motility agents Gastric residual volumes Head of the bed elevation Use of small bowel feeding tubes The benefits of such protocols would be: to standardize the delivery of EN to automate the provision of EN 1 What do Guidelines say ...
