What is Enteral nutrition (EN)
Tube feeding
-nutritionally balanced liquefied food or formula into the stomach, duodenum, or jejunum
Indications:
-anorexia
-orofacial fractures
-head/neck cancer
-neurologic
-psychiatric conditions
-extensive burns
-critical illness
-chemotherapy
-radiation therapy
Contraindications to enteral nutrition
-intentional obstruction
-ileus
-peritonitis
-bowel ischemia
-intractable vomiting and diarrhea
Enteral nutrition formulas and delivery options
-variety of formulas for patients with diabetes, liver, kidney, and lung disease
-concentrations from 1 to 2 cal/mL
-osmolarity, amount of protein, sodium, and fat vary
Delivery options:
-continuous infusion by pump
-cyclic feeding by pump
-intermittent by gravity
-intermittent bolus by syringe
Esophagastroduodenoscopy (EGD)
Visualize esophagus, stomach, duodenum
-detects inflammation, ulcerations, tumors, varices, or mallory-weiss tears
Before:
-NPO for 8 hrs
-explain that local anesthesia may be sprayed on throat
-verify signed consent
After:
-keep NPO after procedure until gag reflex returns
-gently tickle back of throat to test gag reflex
-use warm saline gargles for relief of sore throat
-check temp q15-30min for 1-2 hr
Colonoscopy
Examination of colon, biopsies and polyps removed; bowel prep before and observe for

Complications of a colonoscopy
-Abdominal cramps
-Rectal bleeding
-Perforation
(malaise, abdominal distention, tenesmus)
Nasogastric tube
Nutrition, medication and decompression; proper technique during use, verify placement
-bc of small diameter they are more easily clogged when feedings are thick and are
more difficult to use for checking residual volumes
They are particularly prone to obstruction when oral drugs have not been thoroughly
crushed and dissolved in water before administration
-Can be dislodged by vomiting or coughing
-Can be knotted/kinked in GI tract
NG tube management
Check Aspiration risk before inserting
Obtain x-ray to confirm tube placement
If intermittent delivery is used HOB should remain elevated 30-60 min after feedings
Check gastric residual volumes before each feeding and every 4 hours during the first
48 hrs
Mark exit site at time of initial x-ray and check tuber external length at regular intervals
Observe for negative pressure when attempting to withdraw fluid from feeding
Provide skin care around tube and assess daily (rinse with sterile water )
What are the main complications of tube feedings?
