  • 1. NUTRITION SUPPORTNoraishah Mohamed NorDept Nutrition ScIIUM
  • 2. INTRODUCTION
  • 3. CONDITIONS THAT REQUIRE SPECIALIZEDNUTRITION SUPPORT  Enteral —Impaired ingestion —Inability to consume adequate nutrition orally —Impaired digestion, absorption, metabolism —Severe wasting or depressed growth  Parenteral  Gastrointestinal incompetency (diminished intestinal fx)  Hypermetabolic state with poor enteral tolerance or accessibility  Supplement to EN
  • 4. CONDITIONS IN ENDiminished food intake  Preoperative malnutrition  Coma  Postoperative ileusHypercatabolic states  Polytrauma  Burn  Sepsis  Severe disease condition
  • 5.  Diminished digestion and absorption  Pyloric stenosis  Pancreatic disease  Biliary disease  Malabsorbtion syndrome  Short bowel syndrome  Radiation enteritis  Ulcerative colitis  Duodenal fistula Chronic disease  Chronic cardiac, hepatic, renal disease  Malignant disease
  • 6.  Changes in metabolic rate and nitrogen excretion with various types of physiologic stress
  • 7. INDICATIONS FOR ENTERAL NUTRITIONInadequate amount nutrients and/or calories ingested will lead to malnutrition- associated with an increased incident of:  Poor wound healing  Impaired immune response and response to trauma  Increased risk of sepsis  Altered gut structure/function causing malabsorption and spread of bacteria
  • 8. Ultimately malnutrition will lead to: Prolong recovery period Increased need for nursing care Increased risk of serious complications Prolong hospital stay Increased medical cost
  • 9. CONTRAINDICATIONS FOR EN Severe acute pancreatitis High output proximal fistula Inability to gain access Intractable vomiting or diarrhea Aggressive therapy not warranted Inadequate resuscitation or hypotension; hemodynamic instability Ileus Intestinal obstruction Severe G.I. Bleed Expected need less than 5-7 days if malnourished or 7-9 days if normally nourished
  • 10. ADVANTAGES - ENTERAL VS PN Preserves gut integrity Possibly decreases bacterial translocation Preserves immunological function of gut Reduces costs Fewer infectious complications in critically ill patients Safer and more cost effective in many settings
  • 11. ADVANTAGES - ENTERAL NUTRITION Intake easily/accurately monitored Provides nutrition when oral is not possible or adequate Supplies readily available Reduces risks associated with disease state
  • 12. DISADVANTAGES—ENTERAL NUTRITION GI, metabolic, and mechanical complications—tube migration; increased risk of bacterial contamination; tube obstruction; pneumothorax Costs more than oral diets (not necessarily) Less ―palatable/normal‖: patient/family resistance Labor-intensive assessment, administration, tube patency and site care, monitoring
  • 13. DISADVANTAGES - PN Gut mucosal athropy Overfeeding Hyperglycemia Increased risk of infectious complications Increased mortality in critically ill pt
  • 14. AIMS OF NUTRITIONAL SUPPORT Preserve lean body mass (protein) Increase protein synthesis Improve immune and muscle function More rapid recovery Shorten hospital stay Reduction of morbidity
  • 15. ROLES OF NUTRITION SUPPORT DIETITIAN Working with other health care professionals inc. pharmacist, nurse, clinician-to support, restore, maintain optimal nutritional health for individuals with potential or known alterations in nutritional status Assures optimal nutrition support though implementation of nutrition care process related to delivery of EN and PN support (Fuhrman et al 2001)
  • 16. Nutrition care process Individual nutritional status assessment Indentify nutritional diagnosis Implement appropriate interventions Monitor & reassess an individual’s response to the nutrition care deliveredEvaluate outcomes-incl. the need for transitional feeding care plan or termination of nutr. Support intervention (Lacey & Pritchett, 2003)
  • 17. ALGORITHM TO CHOOSE NUTRITIONAL SUPPORT Nutritional assessment of the patient Normally nourished but willNormally nourished malnourished develop malnutrition because of disease process if support withheld Normal feeding Nutritional support indicated
  • 18. DIFFERENT WAYS TO PROVIDE NUTRITIONSUPPORT Oral Enteral Parenteral Combined
  • 19. WHEN THE GUT WORKS – USE IT!
  • 20. SIGNS OF FUNCTIONING GIT The present of bowl sound Soft, non-tender abdomen Passage of fistulas/stool Intact appetite
  • 21. ENTERAL NUTRITION BY MOUTH Common sense  Adequate  Palatable  Varied  Nutritional complete  Provided at regular intervals, more frequentyly than regular meal times if necessary  Progressively increasing in heaviness and complexity
  • 22.  Cleanliness  In preparation and serving of food and utensils to prevent GIT infection Compassion  Ensuring the patient ingests the preferred food  Putting food in patient’s reach  Conducive eating environment  Involving dietitians in food selection and preparation
  • 23. ENTERAL NUTRITION BY TUBE Nutrition provided through the gastrointestinal tract via a tube, catheter, or stoma that delivers nutrients distal to the oral cavity Benefits of EN:  Help maintain gut mucosal physiology  May modulate immune response-prevent translocation of bacteria and toxins (maintain gut mucosal integrity)- IgA in EN (IgA prevent absorption of enteric antigents)-less risk for infection  Promote peristalsis  Safer: fewer complication  Lower cost-formula, delivery system and less patient care  Simpler system-care and self-administrator
  • 24. CLINICAL SETTING IN WHICH ENTERAL NUTRITIONSHOULD BE PART OF ROUTINE CARE PEM with inadequate oral intake of nutrients for the previous 5 days Oral intake <50 % of required needs for the previous 7- 10 days Severe dsyphagia due to strokes, brain tumors, head injuries, multiple sclerosis Major (>30 % of BSA), full thickness burns Short gut due to small bowel resection-enteral nutrition + parenteral nutrition to stimulate regeneration of the remaining intestine
  • 25.  Clinical conditions in which enteral nutrition usually may be helpful:  Major trauma with functional GIT + inadequate oral intake for 7-10 days  Radiation therapy for cancers of the lungs, head, neck and cervix, and lymphomas  Acute/chronic liver failure + severe anorexia + functioning GIT  Severe renal dysfunction (<5% of normal glomerular filtration) + anorexia + functioning GIT
  • 26.  Contraindications for enteral feeding:  Mechanical obstruction of GIT  Prolong ileus  Severe GI haemorrhage  Severe diarrhoea  Intractable vomiting  High-output GIT fistula (>500 ml/day)  Severe enterocolitis
  • 27. TUBE FEEDING ROUTES
  • 28. TRANSNASAL PASSAGE Transnasal passage of feeding into the stomach/intestine employed when possible  A surgical procedure can be avoided  Generally well tolerated when small-bore feeding tube are used  Disadvantages:  tube can be readily removed by disorientated/uncooperative px.  When larger, stiffer tube used-irritation to nasal passages, pharynx, esophagus & compromise gastroesophageal competency
  • 29.  Nasogastric  insertion & placement of the tube is easier. Nasogastric, esophagostomy, gastrostomy  feeding allow the digestive process to begin in the stomach-decreasing risk of dumping syndrome.  Disadvantage:  higher risk of aspiration-only gastroesophageal sphincter is operating to prevent reflux
  • 30.  Nasoduodenal, nasojejunal, jejunostomy:  Advantage:  Posed less risk of regurgitation-advantage of gastroesophageal sphinctar & pyloric sphincters  Disadvantages:  Higher risk of intolerance (nausea, vomiting, diarhea, cramps)-when feeding are not properly selected.  The bactericidal effect of HCL in the stomach is bypassed-need attention for sanitation to formula and equipment
  • 31. OSTOMIES Require surgical insertion. Indicated when insertion through transnasal is impossible or when long-term feeding is anticipated Advantages:  irritation caused by the feeding tube is eliminated  Ostomies are unobtrusive between feeding time
  • 32.  Jejunostomies:  Advantage:  permits early post operative feeding (unlike stomach & colon)-the small bowel is not affected by postoperative ileus.  Relatively safe, comfortable, potential for long-term use  Disadvantage:  Possibility of infection is high like other ostomy procedure
  • 33. EN ADMINISTRATION Administration of EN should be guided by:  Px’s age  Underlying disease  Enteral access device  Condition of GI
  • 34.  When the patient should be started with EN?  Eary initiation of EN is beneficial if px is hemodynamically stable  In ICU, when EN was initiated within 24-48 hrs of admission:  Lower rates of infection  Shorter hospital stay (Bar et a. 2004)
  • 35. METHODS OF DELIVERYBased on: Nutrient needs Feeding site Formula selection Current medical status3 methods of delivery: 1. Bolus feeding 2. Intermittent bolus feeding 3. Continuous feeding
  • 36.  Bolus feeding:  Administered using a syringe/feeding reservoir  Infused over a period of time  Tolerance is dependent on the functional ability of the gut  Generally, the px is fed a vol of 250-400ml of formula- 5-8x/day  Allow px greater freedom/movement between feeding times  Associated with high incidence of complications:  Nausea  Vomiting  Diarrhoea  Abdominal distension & cramps  Aspiration
  • 37.  Intermittent bolus feeding:  Administered by slow gravity drip  Each feeding is given over 30 min every 3-4 hrs  Tolerance is dependent in the functional ability of the gut  Initiation of feeding with 50 ml of isotonic formula (<30ml/min) every 3-4 hrs  Progression of feeding regime with additional 50 ml every 8-12 hrs as tolerated  Generally, prescribed vol of formula 250-400 ml infused over a 20-30 min period 5-8x/day  Allow px greater freedom/movement between feeding times.  Complications can be similar to bolus feeding
  • 38.  Continuous feeding  Utilised when bolus/intermittent feedings are not tolerate/in critical ill patients/small bowel feeding  Usually pump assisted  Associated with reduced incidence of high gastric residual, GER and aspiration  Restricts px movement
  • 39.  Continuous tube feeding i. Initiation of tube feeding range from 20-50ml/hr ii. Progression of tube feeding range from 10-20ml/hr every 8-24 hrs until the desired volume is attained iii. the strength can be increased as tolerated. iv. If feeding is not tolerated-reduce the rate & strength to previously tolerated level-gradually increase the rate & strength again v. Avoid altering rate & strength at the same time

  • 52. IMMUNE-ENHANCING FORMULAS Have added ―immune-enhancing‖ nutrients (arginine, glutamine, omega-3 fatty acids, nucleotides) Results of research have been mixed Multiplicity of active ingredients makes it difficult to control variables Meta-analysis suggests that they might be most beneficial in surgical patients Some evidence of harm in septic patients
  • 53. EVIDENCE- BASED Glutamine should be added to standard formula in:  Burn & trauma patients In Burns pt, the trace elements (Cu, Zn, Se) should be supplemented in higher dose For the trauma patient, it is not recommended to routinely use immune-enhancing EN, as its use is not associated with reduced mortality, reduced LOS, reduced infectious complications or fewer days on mechanical ventilation. Diet supplemented with arginine should not be used for critically ill pts.
  • 54. FORMULAS FOR IMPAIRED GI FX:INFANT/CHILDREN Protein Hydrolysate  Pregestimil  Alimentum Peptide/ Elemental  Neocate  Peptamen Jr.  Vivonex Pediatric  Neocate advance
  • 55. INITIATION OF FEEDING Choose full strength, isotonic formulas for initial feeding regimen. Initiation and advancement of enteral formula in pediatric patients is best done over several days in a hospital setting using a flexible nutrition plan.
  • 56. INITIATION OF FEEDING- PAEDIATRICContinuous feeding Generally children are started  isotonic formula at a rate of 1-2 mL/kg/h for smaller children  1mL/kg/h for larger children over 35-40 kg.  The rate is advanced based on tolerance by the child  the goal of providing 25% of the total calorie needs on day 1.Bolus feeding  2.5-5 mL/kg can be given 5-8 times per day with gradual increases in this volume to decrease the number of feedings to closer to 5 times daily.
  • 57. INITIATION OF FEEDING-CHILDREN Bolus feedings & gravity-controlled feedings  started with 25% of the goal volume divided into the desired number of daily feedings.  Formula volume may be increased by 25% per day as tolerated, divided equally between feedings Pump-assisted feedings  A full-strength, isotonic formula can be started at 1-2 mL/kg/h and advanced by 0.5-1 mL/kg/h every 6-24 hrs until the goal volume is achieved
  • 58. For preterm, critically ill, or malnourished children  Use pump  initial volume : 0.5-1 mL/kg/hour  Advancing to 10-20 ml/kg/day
  • 59. INITIATION OF FEEDING-ADULTS Bolus feedings & gravity-controlled feedings  full-strength formula  3-8 times per day  increases of 60-120 mL every 8-12 hours as tolerated up to the goal volume. Pump-assisted feedings  initiated at full strength at 10-40 mL/h and advanced to the goal rate in increments of 10-20 mL/h every 8-12 hours as tolerated
  • 60. PATIENT POSITIONING Elevatethe backrest to a minimum of 30º-45º, for all patients receiving EN unless a medical contraindication exists.  Eg.unstable supine, hemodynamic instability, prone position If necessary to lower the Head-to-bed (HOB) for a procedure or a medical contraindication, return the patient to HOB elevated position as soon as feasible.
  • 61. FLUSHES-PRACTICE RECOMMENDATIONS Flush feeding tubes with 30 mL of water every 4 hours during continuous feeding or before and after intermittent feedings in an adult patient flushthe feeding tube with 30 mL of water after residual volume measurements in an adult patient Flushing of feeding tubes in neonatal and pediatric patients should be accomplished with the lowest volume necessary to clear the tube
  • 62. MEDICATION ADMINISTRATION Do not add medication directly to an enteral feeding formula. Avoid mixing together medications intended for administration through an enteral feeding tube to reduce risks of:  physical and chemical incompatibilities,  tube obstruction  altered therapeutic drug responses Dilute medication appropriately prior to administration.
  • 63. REFEEDING SYNDROME Severefluid and electrolyte shifts and related metabolic complications in malnourished patients undergoing refeeding. These complications are often worsened by overfeeding or by use of aggressive repletion.
  • 64. PHYSIOLOGIC CHANGES OCCUR DURINGREFEEDING Intracellular mineral depletion  Hypophosphatemia  hypomagnesemia,  Hypokalemia  body fluid disturbances (―refeeding edema‖)  vitamin deficiencies (eg, thiamine) lifethreatening  cardiac arrythmias  respiratory arrest  Congestive heart failure
  • 65. CONSEQUENCES OF ELECTROLYTE ABNORMALITIESElectrolytes Consequence PO4 Acute ventilatory failure Arrythmias Confusion Congesive heart failure Lethargy, weakness Rhabdomyolysis K+ Arrythmias Cardiac arrest Constipation / ileus Polyuria / polydipsia Respiratory depression Weakness Mg2+ Anorexia Arrythmias Confusion Diarrhoea / constipation Weakness
  • 66. PATIENTS AT HIGH RISK OF REFEEDING Patients with any of the following:  BMI < 16 kg/m2  Unintentional weight loss >15% within the last 3-6 months  Very little or no nutrition for >10 days  Low levels of potassium, magnesium or phosphate prior to feeding
  • 67.  Patients with 2 or more of the following:  BMI < 18.5 kg/m2  Unintentional weight loss >10% within the last 3-6 months  Very little or no nutrition for >5 days  A history or alcohol abuse or some drugs including insulin, chemotherapy, antacids or diuretics
  • 68. MONITORING FOR REFEEDING SYNDROME Monitoring metabolic parameters prior to the initiation of EN feedings and periodically during EN therapy should be based on protocols Prevention of refeeding syndrome is of utmost importance Pxat high risk for refeeding syndrome and other metabolic complications should be followed closely, and depleted minerals and electrolytes should be replaced prior to initiating feedings.
  • 69.  Patientsat risk of developing refeeding syndrome should be identified, electrolyte abnormalities should be corrected prior to the initiation of nutrition support. Nutrition support should be initiated at approximately 25% of the estimated goal and advanced over 3-5 days to the goal rate. Serumelectrolytes and vital signs should be monitored carefully after nutrition support is started
  • 70. CHALLENGES IN NUTRITIONAL SUPPORT1. Caloric requirement not met  Under ordering by physician  Reduced delivery  Slow advancements2. Gut dysfunction  High residual volume (GRV)  Nausea  Vommiting  Absent of bowel sound  Diarrhea  Aspiration
  • 71. 3. Procedure and diagnostic test  require fasting4. Lack of enthusiasm, personal bias and individual practice
  • 72. THE RISK FACTORS FOR ASPIRATION Sedation supine patient positioning the presence and size of a nasogastric tube malposition of the feeding tube mechanical ventilation, vomiting bolus feeding delivery methods poor oral health nursing staffing level advanced patient age
  • 73. STRATEGIES TO OPTIMIZED DELIVERY& MINIMIZED RISK1. Use feeding protocol2. Motility agent (eg. Prokinetic)3. Small bowel vs gastric feeding4. Body position5. Nutrition support practice
  • 74. FEEDING PROTOCOLe.g.Prospective evaluation before and after evidence based protocol introduction of EN in surgical pt.. Within 24 – 48 hr  With the protocol: Inceased delivery of nutirents Shortened duration of mechanical ventilation Decrease mortality
  • 75. PROKINETIC AGENT: METOCLOPRAMIDE IVadministration of metoclopramide or erythromycin should be consider in pt with intolerance to EF  E.g with high gastric volume
  • 76. LEVELS OF GRVSeverity Definition TreatmentMild <200 ml •Return GRV •Continue feedingModerate 200 – 500 ml •1st episode continue •2nd episode start prokinetic agent • 3rd episode reduce EN by half • 4th episode: •Stop feeding •Place NJ tube •Start EN protocol againSevere > 500 ml •Stop gastric feeding •Place NJ tube •Start EN protocolRefer MNT pg 10 other assessment of tolerance
  • 77. SMALL BOWEL FEEDINGSmall bowel fed pt have improved energy delivery in some studiesDuodenal vs gastric feeding in ventilated blunt trauma pt  Improved tolerance ofEN and consequent faster achievement of desired calories Kortbreek JB J Trauma
  • 78.  Small bowel vs gastric feeding  Maybe associated with a reduction in pneumonia in critically ill pt  No different in mortality or ventilation days  Small bowel feeding improves cal & prot intake and is associated with less time taken to reach target rate of enteral nutrition.
  • 79. NUTRITION SUPPORT PRACTICESHow should pt be tube fed aftersurgery?  TF should be initiated within 24 hr after surgery  Sholud satrt with low flow rate (e.g 10 - 20 (max) ml/hr)due to limited intestinal tolerance  May take 5 – 7 days to reach the target intake  Not consider harmful
  • 80. NUTRITION SUPPORT PRACTICES DO NOT…………..:1. Assemble feeding system on the pt’s bed2. Top up fresh formula until the formula hanging in the feeding bag has finished3. Overfed patients:  High calorie density formula  1.3 kcal/ml  Perative  1.5 kcal/ml  Pulmocare  2.0 kcal/ml  nepro/enercal plus
  • 81. OPEN VS CLOSED SYSTEM Open System:  Product is decanted into a feeding bag  Allows modulars such as protein and fiber to be added to feeding formulas  Less waste in unstable patients (maybe)  Shortens hang time  Increases nursing time  Increased risk of contamination
  • 82.  Closed System or Ready to Hang:  Containers sterile until spiked for hanging  Can be used for continuous or bolus delivery  No flexibility in formula additives  Less nursing time  Increases safe hang time  Less risk of contamination  More expensive than canned formula
  • 83. Open System Closed System Hangtime 8 hours for  Hang time 24-48 hours decanted formula; 4 based on mfr hours for formula mixtures recommendations Feeding bag and  Y port can be used to tubing should be deliver additional fluid rinsed each time and modulars formula replenished  May result in less formula Contaminated waste as open system feedings are formula should be associated with pt discarded p 8 hours morbidity
