Presentation Transcript

  1. Care of Patients with Malnutrition and Obesity Alterations in Metabolism

  2. Nutrition Standards for Health Promotion and Maintenance • Dietary Guidelines for Americans • Food Guide Pyramid • Vegetarian Food Guide Pyramid • Cultural awareness • Geriatric considerations

  3. Food Guide Pyramid

  4. Nutritional Assessment • Initial nutritional screening • Anthropometric measurements • Body mass index • Skin-fold measurements

  5. Malnutrition • Protein-calorie malnutrition • Marasmus calorie malnutrition, in which body fat and protein are wasted, serum proteins are often preserved • Kwashiorkor • Marasmic-kwashiorkor

  6. Eating Disorders • Anorexia nervosa • Bulimia nervosa

  7. Patient-Centered Collaborative Care • Patient history • Clinical manifestations • Psychosocial assessment

  8. Laboratory Assessment • Hemoglobin • Hematocrit • Serum albumin, thyroxine-binding prealbumin and transferrin • Cholesterol • Total lymphocyte count

  9. Medical Nutritional Supplements

  10. Drug Therapy • Drugs to stimulate appetite—Periactin, Megace

  11. Total Enteral Nutrition (TEN) • Those patients who can eat but cannot maintain adequate nutrition by oral intake of food alone • Those patients who have permanent neuromuscular impairment and cannot swallow • Those patients who do not have permanent neuromuscular impairment but are critically ill and cannot eat because of their condition

  12. Methods of Administering Total Enteral Nutrition • Nasoenteric tube (NET) • Nasogastric tube (NG) • Nasoduodenal tube (NDT)

  13. Enterostomal Feeding Tubes • Gastrostomy • Percutaneous endoscopic gastrostomy (PEG) • Low-profile gastrostomy device (LPGD) • Jejunostomy

  14. Administration of Tube Feedings • Bolus feeding • Continuous feeding • Cyclic feeding

  15. Complications of Total Enteral Nutrition • Refeeding syndrome • Tube misplacement and dislodgement • Abdominal distention and nausea and vomiting • Fluid and electrolyte imbalances

  16. Parenteral Nutrition • Partial parenteral nutrition • Total parenteral nutrition

  17. Complications of Parenteral Nutrition • Fluid imbalances • Electrolyte imbalances

  18. Community-Based Care • Home care management • Health teaching • Health care resources

  19. Obesity • Overweight—increase in body weight for height compared with standard, or up to 10% greater than ideal body weight • Obesity—excess amount of body fat when compared with lean body mass, at least 20% above upper limit of normal range for ideal body weight • Morbid obesity—severe negative effect on health, usually more than 100% above ideal body weight

  20. CDC data

  21. Populations With High Rates of Overweight and Obesity • More than half of adults in the United States are estimated to be overweight or obese. • The proportion of adolescents from poor households who are overweight or obese is twice that of adolescents from middle- and high-income households. • Obesity is especially prevalent among women with lower incomes and is more common among African American and Mexican American women than among white women. • Among African Americans, the proportion of women who are obese is 80 percent higher than the proportion of men who are obese. • This gender difference also is seen among Mexican American women and men, but the percentage of white, non-Hispanic women and men who are obese is about the same.

  22. Common Complications of Obesity • Hypertension • Hyperlipidemia • CAD • Stroke • Peripheral arterial disease • Metabolic syndrome • Obstructive sleep apnea • Obesity hypoventilation syndrome

  23. CDC data

  24. Common Complications of Obesity (Cont’d) • Depression and other mental health problems • Urinary incontinence • Cholelithiasis • Gout • Chronic back pain • Early osteoarthritis • Decreased wound healing

  25. Etiology and Genetic Risk • Diet • Physical inactivity • Drug treatment • Familiar and genetic factors

  26. Patient-Centered Collaborative Care • Patient history • Clinical manifestations • Psychosocial assessment

  27. Obesity in children

  28. Nonsurgical Management • Diet programs • Nutrition therapy • Exercise program • Drug therapy—Meridia, Tenuate, Bontril, Xenical • Behavioral management • Complementary and alternative therapies—acupuncture, acupressure, ayurvedic therapy hypnosis

  29. Surgical Management • Liposuction • Bariatrics—branch of medicine that manages obesity and its related diseases: • Gastric restrictive • Malabsorption • Both • Preoperative care

  30. Operative Procedures • Gastric restriction

  31. Operative Procedures (Cont’d) • Malabsorption surgery • Gastric bypass

  32. Postoperative Care • Airway management • Pain management • Patient and staff safety • Care of NG tube • Assess for anastomotic leaks

  33. Special Considerations After Bariatric Surgery • Abdominal binder • Position • Monitor SaO2 • Sequential compression hose and/or heparin • Assess skin • Absorbent padding • Remove urinary catheter within 24 hours

  34. Special Considerations for Bariatric Surgery (Cont’d) • Assist patient out of bed • Ambulation as soon as possible • Monitor abdominal girth • 6 small feedings and prevent dehydration • Observe for signs of dumping syndrome
