Flashcards in Surgery Nutrition Deck (9)
What on physical exam may suggest malnutrition?
-increased susceptibility to infection
-poor wound healing
-increased frequency of decubitis ulcers
-overgrowth of bacteria in GI
-angular cheilosis (dry cracked lips)
-extremities: edema, muscle wastin g
-neuro: peripheral neuropathy
-ecchymosis, petechiae, pressure ulcers
-evidence of heart failure.
Lab evaluation of Nutrition
--serum albumin (less than 2.2g/dL = poor outcomes)
--serum transferrin (reflects Fe status)
T/F pts undergoing surgery have better outcomes if they are healthy, eat high protein and caloric diets.
True. if they are not and require surgery then they need parenteral nutrition. may benefit to have delayed surgery to get nutrition if severe malnutrition.
What is the difference between enteral and parenteral feedings?
Enteral = nutrition via intestinal route
Parenteral = nurtrition per IV solution
Benefits of enteral feeding?
Lead to more rapid of PO feedings
shorter hospital stays
Enteral nutrition consists of what?
How is enteral nutrition administered?
Calories, protein, electrolytes, vitamins, minerals, & fluid.
-NG or nasoenteric tube (less than 30d)
-nasojejunal tubes (used for those with impaired stomach motility, increased risk of aspiration) (also short term)
-PEG (used for extended period of time)
-percutaneous jejunostomy tubes
Complications of Tube feedings
Diarrhea (from meds, composition of feeding, infusion rate)
-what is this?
What: can follow rapid infusion of feeds via jejunal tubes or rapid gastric bolus feeds.
Sx: faintness, palpitations, diaphoresis, pallor, tachycardia, and hypoglycemia
Tx: slow rate of feeding or change formula to one with more complex carbs
