Module IModule I

Enteral Nutrition• Definition—administration of

nutrients directly into the GI tract• Beneficial when oral feedings are

not possible, but the stomach or intestines are able to digest nutrients

• Preferred over parenteral nutrition

Evidence-Based Practice

• Indications– Impaired swallowing or gag reflex

usually related to a neurological process

– Nutritional deficit due to decreased food ingestion

– Inability to eat related to surgery, injury, or disease

Continued…• Complications

– Displacement of tube– Electrolyte imbalance– Hyperglycemia– Constipation – Diarrhea– Clogging of the tube– Vomiting– Pulmonary aspiration

Enteral Feeding• Types

– Nasogastric—a small tube that is passed through the nares into the stomach

– Nasointestinal—tungsten-weighted tube inserted through the nares to allow peristalsis to move the tube through the pyloric sphincter into the duodenum or jejunum

– Gastrostomy—surgically placed feeding tube inserted into the stomach in the LUQ of the abdomen

Insertion of a Nasogastric or Nasointestinal Tube

• Refer to Skill 30-1, pg 1014

Verifying Tube Placement

• X-ray after initial insertion• pH of aspirate• Air bolus auscultation • Aspiration of gastric contents or

feeding

NG Tube Irrigation• Refer to Skill 30-3, pg 1025

Types of NG Feedings

• Intermittent or Bolus

• Continuous drip

Equipment for Feeding• Clean gloves• 60cc syringe or feeding bag• Formula

Feeding Administration• Refer to Skill 30-4, pg 1028

Evaluation of Feeding• Measure residual per policy—notify

MD if >100cc• Monitor blood sugar levels per

policy• Intake and output every 8 hours• Monitor lab values—albumin,

prealbumin, protein, transferrin

Continued…• Daily weights• Assess respiratory status• Assess level of comfort• Assess abdomen—bowel sounds

Gastrostomy Feedings• Refer to Skill 30-5, pg 1036
