Nutrition Ch 24
Nutrition & Severe Stress
Question | Answer |
---|---|
List some examples of severe stress | Burns, Infection, and Trauma |
What happens to the body during fasting? | Body conserve protein, the metabolic rate decreases, call adapt to using ketones for energy |
What happens to the body during stress? | Metabolic rate stays high and body break down protein for fuel |
Effect of malnutrition and severe stress | Unable to maintain a successful stress response and higher risk of death |
Chronic Malnutrition | Depleted fat stores and lean body mass, blood proteins & immune function are adequate |
Acute Malnutrition | Depleted lean body mass, blood proteins & immune function, but not fat stores |
Mixed Malnutrition | Lean body mass, blood proteins, immune function and fat stores are all depleted |
Nutrition Support during stress | Fluid & electrolytes are given by IV, progressive diet, and more calories are req. |
Progessive Diet | Slow change from clear liquids (Apple Juice) to full liquids (Milk), low fiber (Apple Sauce) to regular food |
What is the calories requirement if fever is involved with stress event? | 7% more for every degree (F) above normal |
2 dangers of deliverig nutrients thru the GI tract immediately after the stress period | Intestinal distention & perforation and Regurgitation into the lungs |
Refeeding Syndrome | Complications that are associated w/ reintroducing nutrients after stress event |
What are some examples of complications of refeeding syndrome? | Respiratory distress, Congestive heart failure, Convulsations and Coma |
Infections | Invation of pathogens, anemia usually develops b/c iron is sequestered and kidney don't replaces the iron in blood |
Nutrition needs in trauma and surgery | Good preoperation- decrease complications, NPO at least 8hrs- prevent vomiting/aspiration, and progressive diet |
Organ Transplantation | Requires precaution against food-borne illnesses b/c they are given immunosuppressive drugs |
1st Degree Burn | Damage the epidermis, usually redness and pain |
2nd Degree Burn | Epidermis and top part of dermis, usually blisters |
3rd Degree Burn | Epidermis, dermis and hypodermis are damage |
Burn Care | Need fluid, electrolytes, and albumin b/c they leak from area and protein req. is 2 to 3x RDA |
Protective mechanisms of the GI tract | Villi form a barrier, Goblet cells secrete mucus, Peyer's patches (lymph nodes), and IGA is secrete in mucus & saliva |
Factors that increase the chance of translocation | Reduce blood flow to intestine, parenteral nutrition, malnutrition, immunosuppresive drugs, and antibotics |
Enteral feeding | Deliverance of nutrient thru the GI tract |
Parenteral feeding | Deliverance of nutrient thru vein |
Glutamine | Most abundant amino acid, provide fuel for intestinal cells, required for synthesis of nucleotides, essential during stress event |
Short chain fatty acids | 2-4 C long, made by bacteria in GI, provide fuel to large intestine, stimulate intestinal cell growth & blood flow |
