Clinical Nutrition Outline • Malnutrition - definition - types • Physiology - fasting - starvation - stress & trauma • Nutritional Assessment • Nutritional Support - timing - enteral vs. parenteral - calculations Clinical Nutrition Nutrition • intake of nutrients to provide energy for - performance of mechanical work - maintenance of organ/tissue function - heat production - maintenance of metabolic homeostasis • TEE (total energy expenditure) - REE or BEE (fasting resting or basal energy expenditure) ~ 70% (~1 kcal/kg/hr) - activity expenditure ~ 20% avg. but very variable - thermic effect of feeding ~ 10% (intake increases ...
