Nutritional support is defined as "the administration of nutrients for assimilation and utilization by a patient by means other than normal eating."[1]

Classification[edit]

Enteral nutrition[edit]

Enteral nutrition, which is defined as "nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes."[2]

Duodenal feeding may be more effective than gastric feeding.[3]

For critically ill patients who are intolerant of tube feeding, combining two prokinetic drugs, 200 mg of intravenous erythromycin twice daily with 10 mg of intravenous metoclopramide four times daily may be more effective than using either drug alone.[4]

For profit hospitals are more likely to use PEG tubes in nursing home patients.[5]

Parenteral nutrition[edit]

Parenteral nutrition, which is defined as "the administering of nutrients for assimilation and utilization by a patient who cannot maintain adequate nutrition by enteral feeding alone. Nutrients are administered by a route other than the alimentary canal (e.g., intravenously, subcutaneously)."[6] Parenteral nutrition is usually administered via a central venous catheter.

Nutrition assessment[edit]

Nutrition assessment is "valuation and measurement of nutritional variables in order to assess the level of nutrition or the nutritional status of the individual. Nutrition surveys may be used in making the assessment."[7] Prealbumin, which includes transthyretin, alpha-1-antitrypsin, transthyretin and orosomucoid, can help assessment because if its short half-life of 2 days.[8]

Effectiveness[edit]

In the absence of metabolic diseases such as medium-chain acyl-coenzyme A dehydrogenase deficiency, nutritional supplementation is not necessary if the patient is not eating for four days or less[9] and maybe also if duration is seven days or less.[10]

A randomized controlled trial found no difference between the NG tube and PEG tube in stroke patients.[10]

A randomized controlled trial found that among patients receiving enteral nutritional support in intensive care, adding parenteral nutritional support at day 8 was equivalent to starting within 48 hours.[11]
