Exploring the Tall Tales of Nutrition in the ICULori A. Duesing, MSN, RN, CPNP-AC, APNP

Financial Disclosures

▪ None related to this topic

Objectives

▪ Explain the relationship between nutrition and improved outcomes in the critically ill patient

▪ Understand terminology of relevant gastroenterology disease processes

▪ Recognize situations in which nutrition should be utilized in the critically ill patient▪ Recognize situations in which nutrition should be utilized in the critically ill patient

#1 Myth: Starvation or Under-nutrition is Ok!

▪ Nutrition is essential for survival.

▪ Supports anabolism

▪ Ameliorates uncontrolled catabolism

▪ Maintains a competent immune systemMaintains a competent immune system

▪ Bottom line … nutrition if given at the right time by the right route, will improve patient outcomes

Calorie Intake to meet the needs of ICU patients remains unclearMeta analysis including 4 studies showed:• No significant difference in mortality between under- and full fed group• Subgroup analysis showed underfed group significantly lower mortality when fed >33.3% of

standard requirement in comparison to the full-fed group• No difference in mortality between underfed group fed <33.3% of standard caloric

requirements• LOS and LOICUS did not differ

Indirect calorimetry and predictive equations:• 2349 publications retried, with 18 studies included• Predictive equations underestimated and overestimated energy expenditure in

13-90% and 0-88%, respectively• 43% below and 66% above indirect calorimetry values observed

The latin phrase primum non nocere, translated to “first, do no harm” serves as a reminder to clinicians that good intentions may have harmful consequences. • Use of inaccurate predictive estimates for support of the critically ill• patient combined with aggressive therapy to achieve target nutrition intakes without

consideration of potential consequences of this therapy may have harmful consequences

• Each patient needs to be evaluated closely for signs and symptoms of overfeeding and feeding intolerance

Consensus

▪ Generalized belief that optimal calorie and protein intake are associated with improved patient outcomes

▪ Severity of illness is a variable = less sick patients tolerate EN

▪ Despite these limitations the Society of Critical Care Medicine American Society▪ Despite these limitations, the Society of Critical Care Medicine, American Society of Parenteral and Enteral Nutrition guidelines, and Canadian and European guidelines all recommend

▪ EN be initiated within 48 hours in the critically ill patient who is unable to maintain volitional intake.

▪ There is no known illness or disease that benefits from starvation

“Bowel rest”

▪ Popular in the 1970s for Crohn’s, colitis, acute and chronic pancreatitis, diverticulitis and a number of other GI disorders

▪ Why?

▪ Enteral nutrition (EN) enhances inflammation( )

▪ Removal the stimulus of luminal antigens and bowel function

▪ Contrary:

▪ Starvation does not inhibit bowel function

▪ Starvation decreases splanchnic blood flow resulting in profound structural and functional changes to the GI tract

The splanchnic circulation. Gelman S, Mushlin PS: Catecholamine induced changes in the splanchnic circulation affecting systemic hemodynamics. Anesthesiology 100:434–439, 2004.)

Characteristics of Splanchnic blood flow

▪ Regulates circulating blood volume and systemic blood pressure

▪ In acute hypovolemia, such as hemorrhage, splanchnic circulation is reduced to supply blood and oxygen to vital or essential organs = brain and heart.

▪ A key source of inflammatory mediators▪ A key source of inflammatory mediators

Regulators

Intrinsic

▪ Local metabolic & myogenic control

▪ Blood flow: Vasodilators/vasoconstrictors

Extrinsic

▪ Sympathetic innervations

▪ Increases vascular resistance to decrease blood flow

▪ Local reflexes

▪ Locally produced vasoactive substances

▪ Circulatory vasoactive substances

▪ Systemic hemodynamic changes

#2 Myth: Parenteral Nutrition is Safe!

▪ If the gut works, use it!

▪ Parenteral nutrition (PN) prevents progressive malnutrition in patients unable to feed enterally

▪ Widely accepted to use the GI tract as a preferred route in delivering nutritional▪ Widely accepted to use the GI tract as a preferred route in delivering nutritional support.

▪ Strongly recommended in critically ill and postoperative patients

▪ Although widely accepted, parenteral nutrition is still used in patients who can be fed enterally

Adverse effects of Parenteral Nutrition▪ Double hit if you are not feeding the gut and using PN

▪ Metabolic, immunologic, endocrine and infective complications associated with high glucose concentration and fat globules via the systemic venous system.

▪ PN bypasses the GI tract and liver

▪ EN stimulates enterohormones which are crucial in regulating gut function and metabolic pathways

▪ EN supplies the portal system supplying the liver with a rich source of nutrients and hormones

▪ Increased risk for GI mucosal atrophy, bacterial overgrowth and translocation, increased intestinal permeability

▪ PN is associated with impaired leukocyte chemotaxis, impaired phagocytosis, impaired bacterial and fungal killing and an attenuated inflammatory response

4696 abstracts with 406 articles included:• PNAC directly correlated with length of PN use• No decrease in the past 4 decades• Multidisciplinary teams to treat PNAC/IFALD show improved outcomes• Discussion regarding Omegavan and SMOF to improve outlines

26 Randomized trials of 2211 patients:• PN + oral and IV dextrose = no difference in mortality• PN alone = risk of mortality doubled

#3 Myth: EN is Contraindicated with Vasopressors!

▪ Hemodynamically unstable and/or require vasopressors = common in the ICU

▪ Vasopressors improve hemodynamics as they shunt blood from the gut to the central circulation

▪ Feeding during these times?▪ Feeding during these times?

▪ No, if limited oxygen delivery to the gut, why would you increase oxygen demand by feeding?

▪ Will cause bowel ischemia NCP• In animal models, mesenteric and renal blood flows improved with low dose

enteral nutrition while receiving low dose vasopressin• As vasopressin therapy increased, the benefit of enteral nutrition on mesenteric

perfusion was not maintained• To promote splanchnic perfusion with use of enteral nutrition, the authors

advocate for enteral nutrition ~6 hours post fluid resuscitation

3/6/2015

In endotoxic and septic shock models, enteral feeding improved• hepatic artery and portal vein blood flow• superior mesenteric artery blood flow• intestinal mucosal microcirculatory flow• hepatic microcirculatory flow• hepatic and intestinal tissue oxygenation, and • hepatic energy stores

Prospective study = 886 ICU mechanically ventilated pts• Optimal nutritional therapy associated with a decrease in 28-day

mortality by 50%• Only reaching energy targets is not associated with a reduction in

mortality.

• Multicenter retrospective study showed lower hospital mortality in patients enterally fed within 48 hours

• EN benefits greater in the sickest receiving multiple vasopressors• Early enteral nutrition vs. late enteral group: 22.5% vs 28.3%; P = 03; and 34.0% vs

44.0%; P < .001, respectively• Early feeding = within 48 hours of the start of mechanical ventilation• Late feeding = Later than 48 hours• Protein/energy needs not reviewed

#4 Myth: Early EN is not Important in Patients Receiving Mechanical Ventilation!

▪ The commencement of enteral nutrition is typically delayed in mechanical ventilated patients

▪ Likely cause? Not a current priority and may be pushed to the back burner

▪ Older guidelines support mechanically ventilated patients go 1 weeks without▪ Older guidelines support mechanically ventilated patients go 1 weeks without nutrition.

▪ Mechanical ventilation is a predictor for failure to provide enteral nutrition

• Early EN within 2 days of admission associated with a significant reduction of ICU and hospital morality

• The implementation of an evidenced-based nutritional management protocol significantly shortened the duration of mechanical ventilation

• EN was associated with reduced risk of death

#5 Myth: EN is Contraindicated with High Gastric Residual Volume!

▪ Many monitor gastric residual volume (GRV)

▪ Enteral nutrition is stopped with elevated GRVs

▪ High GRVs do not necessarily predict aspiration

▪ Low GRVs do not necessarily predict aspiration will not occur

▪ Interrupting EN with GRV 100-200mls not shown to decrease prevalence of aspiration

Speculation for GRVs

May have arisen from beliefs:

▪ #1 the stomach is a container of finite size

▪ #2 when input exceeds output over time, the stomach will “overflow”

▪ #3 overflow into … the esophagus which equals aspiration

▪ If we have knowledge of gastric contents at any given time through GRV we will predict risk of overflow and ultimately prevent aspiration

Implications to the theory of High GRVs

▪ GRVs accurately reflect the total volume in the stomach

▪ Formula retained in the stomach will alert the clinician to delayed gastric emptying equaling impending intolerance

▪ Stop the feeding to prevent vomiting or aspiration from occurring▪ Stop the feeding to prevent vomiting or aspiration from occurring

Implications of low GRVs

▪ Presumed to indicate low intra-gastric volume

▪ The formula is being emptied appropriately

▪ Risk for aspiration with a low GRV expected to be minimal, so the patient is tolerating enteral feedingstolerating enteral feedings

Flaws to rationale

▪ Total salivary and gastric secretion = output up to 1500mls salivary and 3000mls gastric secretions

▪ Aspiration of oropharyngeal secretions

▪ Some degree of aspiration may occur normally in normal healthy individuals

▪ Patient populations vary with regard to risk for aspiration pneumonia, specifically risk for aspiration of gastric contents.

▪ Must consider the specific patient:

▪ Communicative patients with functional GI tract = no benefit

▪ Uncommunicative patients with potential for impaired GI tracts = might benefit

▪ Patients with inability to handle oral secretions = no benefit

Do residual volumes impede nutritional support?

▪ GRVs may lead to clogging of feeding tubes = acid mixed with intact proteins in the tube clotting the formula

▪ Low GRVs may give clinicians false sense of security

▪ Institutional threshold values of GRVs guide the clinician to withhold nutrition▪ Institutional threshold values of GRVs guide the clinician to withhold nutrition

• Randomized ICU ventilated patients

• #1 GRV >200ml

• #2 GRV >400mls• Aspiration prevalence was similar between groups

Tests to evaluate for aspiration

▪ Videofluorographic swallow study = “gold standard” modified barium swallow test looking at 3 phases of swallowing (oral, pharyngeal and esophageal phases)

▪ Fiberoptic Endoscopic Evaluation of Swallowing (FEES)

▪ Scintigraphy▪ Scintigraphy

McClave, et al recommends:

• High-risk patient populations should be identified by their disease process, not solely by GRV

• Trauma, head injury, sedated, altered mental status

• Pertinent physical findings suggesting ileus

• Abdominal distention, nausea, vomiting, or overt aspiration or regurgitationg p g g

• Clinicians should not depend on GRVs to distinguish high risk from low risk

• Obvious trend of increasing GRVs should prompt a clinical pathway or algorithm

• Rather than automatic cessation of enteral feeding, consider:

• Prokinetic agent, depending on age

• Reducing sedation

• Sepsis

• Elevate head of bed

#6 Myth: Post-pyloric Feeding Reduces the Risk of Aspiration!

▪ Many clinicians believe critically ill patients should receive post-pyloric feedings.

▪ Undoubtedly, some ICU patients would not tolerate early gastric feeding due to delayed gastric emptying

▪ Underlying co-morbidities

▪ Medications

▪ Electrolyte disturbances, hyperglycemia

▪ Surgery

▪ Shock

▪ No consensus for routine use of post-pyloric feeding and associated decrease aspiration risk

Meta-analysis. • Unable to demonstrate a clinical benefit from post-pyloric versus gastric tube feeding in a

mixed group of critically ill patients, including medical, neurosurgical, and trauma ICU patients.

• The incidences of pneumonia, ICU LOS, and mortality were similar between groups.

Now what, gastric feeding has failed?

▪ Gastric feeding intolerance

▪ Abdominal distension

▪ regurgitation

Timed trial of prokinetics▪ Timed trial of prokinetics

▪ Then, place post-pyloric feeding tube

▪ Known gastric dysmotility and ECMO = post-pyloric feeding

#7 Myth: EN is Contraindicated in Patients Without Bowel Sounds and/or a Postoperative Ileus!

▪ 1905, first clinician to suggest the relationship between bowel sounds and bowel function

▪ Part of the standard physical exam

▪ After abdominal surgery the auscultation of bowel sounds leads to feeding▪ After abdominal surgery, the auscultation of bowel sounds leads to feeding

• Bowel sounds require the swallowing of air and gastric emptying• Small bowel myoelectric activity returned immediately after surgery.• On average, took 2.4 days for the return of auscultated bowel sounds

#8 Myth: EN is Contraindicated Following GI Surgery!

▪ The period of post-operative ileus is believed to last for 3-5 days

▪ Treated with nasogastric tube to low intermittent suction, intravenous fluids, parenteral nutrition

3/6/2015

• Systematic review and meta-analysis of randomised controlled trials comparing any type of enteral feeding started within 24 hours after surgery with nil by mouth management in elective gastrointestinal surgery

• 837 patients, 11 studies• No clear advantage to keeping patients nil by mouth after elective gastrointestinal

resection

Enteral feeding post surgery

▪ Aggressive enteral nutrition does not come without risk

▪ Gastrointestinal intolerance:

▪ Abdominal distention

H t i▪ Hypotension

▪ Shock

▪ Small bowel ischemia or necrosis

▪ High mortality rate

• Before and after episodes of hypotension, the benefits of enteral nutrition warrant a fairly aggressive approach

• The risk:benefit ratio rises steeply during the period of hypotension• Feeds may be continued during this period, as long as there is close clinical monitoring

and a high index of suspicion is maintained for any signs of GI intolerance and the possibility of early mucosal ischemic injury

#9 Myth: EN is Contraindicated in Patients with an Open Abdomen!

▪ NPO or PN

▪ Assumption that enteral nutrition be held due to bowel wall edema and bowel dysfunction

Retrospective review = 78 patients

Early enteral nutrition in the open abdomen was associated with (1)earlier primary abdominal closure(2)lower fistula rate(3)lower hospital charges by $50,000

Retrospective study of 37 pts with ACS:

Enteral feeding was never started in 12 patients; 4 died within 48 hours of admission 7 required vasoactive agents until their death and 1 developed anadmission, 7 required vasoactive agents until their death, and 1 developed an enterocutaneous fistula requiring parenteral nutrition. Enteral feeding was initiated in the remaining 25 patients: 13 had feeds started within 24 hours of abdominal closure; 5 were fed with open abdomens; and 7 had a delay because of vasopressors (n = 2), multiple trips to the operating room (n = 2), paralytics (n = 2), and increased intra-abdominal pressures (n = 1). Once advanced, enteral feeding was tolerated in 23 (92%) of the 25 patients with attainment of goal feeds in a mean of 3.1 +/- 1 days.

#10 Myth: EN is Contraindicated in Patients with Pancreatitis!

▪ In 1991, it was believed in acute severe pancreatitis, total parenteral nutrition be initiated to allow rest of the pancreas and provide nutrient deficits and energy caused by the inflammatory process.

What is pancreatitis?▪ Acute pancreatitis is sudden inflammation of the pancreas that may be mild or life threatening but usually subsides.

▪ Gallstones and alcohol abuse are the main causes of acute pancreatitis

▪ Heredity

▪ Medication

▪ Virus

▪ Cystic fibrosis diagnosis with increased risk▪ Cystic fibrosis diagnosis with increased risk

▪ Severe abdominal pain is the predominant symptom

▪ Whether mild or severe, acute pancreatitis usually requires hospitalization

▪ Gallstones and constant, heavy alcohol abuse account for almost 80% of hospital admissions for acute pancreatitis

▪ Women, ~1½ times that of men caused by gallstones

▪ Normally, the pancreas secretes pancreatic fluid through the pancreatic duct to the duodenum

▪ This pancreatic fluid contains inactive digestive enzymes and inhibitors that inactivate any enzymes that become

activated on the way to the duodenum

▪ Blockage of the pancreatic duct by a gallstone stuck in the sphincter of Oddi stops the flow of pancreatic fluid.

▪ Causing activated enzymes to accumulate in the pancreas, overwhelm the inhibitors, which begin to digest the cells of

the pancreas, causing severe inflammation

N t iti l t h ld b i d ti th ti i t ti th t• Nutritional support should be viewed as an active therapeutic intervention that improves the outcome of patients with acute pancreatitis

• Enteral nutrition should begin within 24 h after admission following the initial period of volume resuscitation and control of nausea and pain

• Patients with mild acute pancreatitis should be started on a low-fat oral diet • In patients with severe acute pancreatitis, enteral nutrition may be provided by

the gastric or jejunal route

Six randomized controlled studies with 263 participants• Enteral nutrition was associated with a significantly lower incidence of infections

(relative risk 0.45; 95% confidence interval 0.26 to 0.78, P = 0.004)• Reduced surgical interventions to control pancreatitis (0.48, 0.22 to 1.0, P =

0.05) Reduced length of hospital stay (mean reduction 2.9 days, 1.6 days to 4.3 days, P < 0.001).

• There were no significant differences in mortality (relative risk 0.66, 0.32 to 1.37, P = 0.3) or non-infectious complications (0.61, 0.31 to 1.22, P = 0.16) between the two groups of patients.

Conclusions Enteral nutrition should be the preferred route of nutritional support in patients with acute pancreatitis.

#11 Patients Must be Fed Semi-recumbent at 45 Degrees!

▪ In 1999, Drakulovic, et al in their randomized controlled study found:

▪ 39 intubated patients in semi-recumbent

▪ 47 intubated patients in supine

▪ Risk for pneumonia was highest in EN fed patients in supineRisk for pneumonia was highest in EN fed patients in supine

▪ Standard nursing care of the intubated patient for the head of bed to be elevated 45 degrees – especially if receiving enteral nutrition

▪ Centers for Disease Controls and Prevention, the Agency of Healthcare Research and Quality and the Institute for Healthcare Improvement all suggest elevating the head of bed to reduce reflux and pneumonia

3/6/2015

Semirecumbent versus supine or near supine

▪ Van Nieuwenhoven, et al (2006) randomized 112 intubated patients = 45 degrees was not achieved 85% of the time

▪ The non-supine patients were repositioned more frequently than supine

▪ No difference in ventilator associated pneumonia

▪ Grap, et al (2005) reported a mean backrest elevation of 21.7 degrees without association to pneumonia

▪ Rose et al (2010) of 2112 backrest elevation measurements in 371 patients in 32 ICUs▪ Rose, et al (2010) of 2112 backrest elevation measurements in 371 patients in 32 ICUs.

▪ 45 degrees = recorded in 5.3% of instances

▪ 30-45 degrees = recorded 22.3% of instances

▪ Nursing a patient semirecumbent at 45 degrees is not feasiable

▪ Attempts may not reduce ventilator associated pneumonia

▪ 45 degree positioning = patient slides down, sacral pressure, uncomfortable for patient

▪ Supine at 0 degrees probably increases the risk of pneumonia; however, no strong evidence that elevation of the head of the bed to 10-30 degrees will increase the risk for pneumonia

Conclusion

▪ Myths delay and limit optimal enteral nutrition

▪ Few exceptions prohibit enteral nutrition = GI bleed requiring endoscopy, surgical problem that must be repaired or planned extubation where oral feeding is likely to be resumed

▪ Early EN is feasible and improves outcomes of critically ill patients

▪ Patients who are about to die or are deceased

The New Opportunities for Verification ofThe New Opportunities for Verification of Enteral Tube Location (NOVEL) Project Update

Lori A. Duesing, MSN, RN, CPNP-AC, APNPDivision of Pediatric Gastroenterology and Nutrition, Medical College of Wisconsin

Objectives:

▪ Discuss NG/OG/post-pyloric tube placement verification in pediatrics

▪ Discuss the NOVEL project mission

▪ Discuss research findings

▪ Discuss future direction

Background

▪ In 2012, a safety alert was distributed by the Child Health Patient Safety Organization recommending the immediate discontinuation of the auscultation method for NG tube placement verification

▪ 1.3-2.4% of NG tube in over 2,000 insertion were located outside of the t i t ti l t tgastrointestinal tract.

▪ 20% of those tubes led to pulmonary complications

▪ Abdominal film is current gold standard

Background continued

▪ In addition to this alert, the American Association of Critical Care Nurses (AACN) issued a practice alert3 and the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) implemented practice recommendations4 to address the risks and potential complications associated with misplaced NG tubes.

▪ American Association of Critical Care Nurses (AACN). AACN Practice Alert: Verification of Feeding Tube Placement (blindly inserted): American Association of Critical Care Nurses; 2010.

▪ Bankhead R, Boullata J, Brantley S, et al. A.S.P.E.N Enteral Nutrition Practice Recommendations. JPEN J Parenter Enteral Nutr. 2009;33(2):122 - 167.

Background continued

▪ Common in hospital and home settings

▪ Used for enteral nutrition, fluids and medication administration

▪ Broad discrepancies regarding verification of placement = lack of literature

▪ Pediatrics more complex than adults: size of patient in relationship to size of tube, goal to minimize exposure to radiation

▪ X-ray is the gold standard, followed by pH

▪ NG tube misplacement can cause serious neurological harm or death

▪ Nurses are primary health care providers who insert NG tubes in the hospital and home settings

Ponder these questions

▪ How many of you have known of or been associated with an adverse outcome?

▪ Do you think NG tube misplacements is under-reported?

▪ What role does quality and safety have in relationship to placement?

▪ Should we be concerned just from this one story?

American Society for Parenteral and Enteral Nutrition (ASPEN)

▪ A literature review revealed very few pediatric studies to guide our practice

▪ ASPEN formed a task force to address this issue

▪ Invited participation from stakeholder organizations

From a nurse“…I placed the NG like I had done hundreds of times in the past, with no complications and checked placement with air bolus and started the feed. The patient ended up coding on the floor and being sent to our PICU where she was intubated and started on ECMO. The moment that the patient went into respiratory distress, my whole life changed. I had not missed a day of work in seven years and went to my nurse manager and told her I needed to leave and could no longer be a nurse, and that I would not be back to work…”from invited commentary in NCP June,2014

Importance of enteral nutritionImportance of enteral nutrition

Atrophy has been observed in the small intestine deprived of nutrient contact either by bypassing the small intestine surgically or by using parenteral nutritionparenteral nutrition

Intravenous feeding following small-bowel resection results in slight mucosal atrophy, whereas enteral nutrition stimulates mucosal hyperplasia

Enteral nutritionEnteral nutrition

Enteral nutrition is also important for stimulating regeneration of the mucosa The combination of parenteral and enteral nutrition is

superior to parenteral nutrition in stimulating intestinal i i f i i h d di hregeneration in a group of patients with protracted diarrhea

of infancy

A more rapid resolution of malabsorption and diarrhea following enteral nutrition alone versus parenteral nutrition in the same disorder has also been observed

Enteral nutrition is also important in maintaining mucosal mass in SBS

Patients then develop large-volume fluid and electrolyte secretions once the ileus resolves, and gastric fluid and ostomy losses may be high Because these losses vary significantly with time, placing the

patient on a standard parenteral nutrition solution is optimal fl d l h b l d b d h

Excessive fluid losses can then be replaced based on the electrolyte content of these secretions as determined in the laboratory

These secretions can be replaced every few hours using a separate fluid and electrolyte solution

Losses tend to be high in sodium and solutions with at least 80 - 100 mEq/L of sodium are needed to maintain fluid and electrolyte homeostasis

The first stage of therapy is the time to replete any nutritional deficiency states that may have

When fluid and electrolyte losses have decreased, a continuous enteral infusion is initiated

Elemental diets are s ally sed

Managing a patient with SBSManaging a patient with SBSFurther managementFurther management

Elemental diets are usually used Some people use a lower concentration of formula

and advance the concentration prior to advancing the rate (this prevents overloading the patient)

Others start at optimal concentrations and advance the rate as tolerated

Continuous enteral infusion is gradually advanced based on the absence of the following: A marked increase in stool loss by more than 50%

In patients with an intact colon, a decrease in stool pH below 5.5 is frequently indicative of carbohydrate malabsorption

Further advancement of enteral feedings is likely to result in a significant increase in osmotic diarrhea in such patients

The use of continuous enteral infusion is advantageous Feedings are frequently better tolerated Emesis is reduced Carrier proteins are continuously saturated and intestinal

function is optimized The increased enteral calories try to increase the functional

workload of the small intestine, resulting in additional stimulation of intestinal adaptation

Administration of extra calories through the enteral route reduces the need for parenteral nutrition and its complications

The appropriate solids to give initially to patients with short-bowel syndrome are a matter of controversy

Tradition has suggested high-carbohydrate diets

Managing a patient with SBSManaging a patient with SBSFurther managementFurther management

Tradition has suggested high carbohydrate diets

These are hyperosmolar and may increase fluid losses

Meat may be the best initial solid Feeding fats or proteins results in less fluid loss

Fat is also a good trophic agent to the small intestine

Enteral formulasEnteral formulas Patients with SBS are given elemental diets

These are diets that contain amino acids rather than peptides However, most protein is absorbed in the form of di- and

tripeptides, so the concept of an elemental diet is extended in pediatrics to partially elemental formulas - extensive protein hydrolysateshydrolysates

Carbohydrates are usually present from one or more sources, including partially hydrolyzed starch and disaccharides such as sucrose

A mixture of medium- and long-chain fats is included Adult elemental formulas are usually inappropriate in pediatrics

deficient in vitamins, minerals, and essential fatty acids tend to be high in carbohydrate content

Alimentum and Pregestimil relatively high in fat content, reducing the osmotic load in the

small intestine Both contain substantial amounts of long-chain fats, important

for their trophic effect

Enteral formulasEnteral formulas

p In older infants and toddlers, fiber-supplemented complex formulas

may be instituted as they produce a firmer stool fiber, through its effect on SCFA production, may play a role in

adaptation Newer ‘amino-acid’ formulas do not confer any absorption

advantage

As parenteral nutrition is decreased and enteral nutrition is increased, intermittent parenteral nutrition can be used.

The patient is given the parenteral portion of his nutrition over an 8 to 16 hour period each day

for the greater part of the 24-hour day, but soon the interval “off ” parenteral nutrition can gradually be increased as the patient’s tolerance of enteral calories increases

Caloric changes are gradually increased, based on the child’s growth needs, to ensure that the child parallels the 50th percentile for both height and weight
