8. Nutritional Assessment
ā¢ Body weight
ā¢ Body mass index
ā¢ Serum proteins:albumin, prealbumin,
transferrin
ā¢ Immune competence: lymphocytes
9. Nutritional Requirements
ā¢ 25 cal/kg/day
ā¢ carbohydrate ~70%
ā¢ Lipid 15-30%
ā¢ Protein 1.5-2.0g/kg/day. Not for calories
ā¢ Additional 50% to 100% for stress as in
ICU patients
11. Enteral Requirements
ā¢ Delivery into the GI tract by tube with
minimum risk of aspiration or patient effort
ā¢ Delivery of nutrients with minimal need for
digestion
ā¢ Control of rate to prevent osmotic diarrhea
12. Advantages of enteral nutrition
ā¢ Easier
ā¢ GI bacterial translocation
ā¢ Cheaper
ā¢ Fewer specific complications
13. Conclusions
ā¢ Nutrition is a powerful determinate of
patient outcome
ā¢ The proper provision of nutrition is a
component of basic patient care
