Immunonutrients in Surgical
Patients
Benny Philippi
Introduction
1. Increased complexity of managing
nutritional support in surgical patients
(trauma, sepsis, critically ill)
2. Malnutrition is a common practice in
these patients
3. Understanding normal nutrition &
metabolic changes is essential for
surgeon

GENERAL
GOAL AND PRINCIPLES
Macronutrients:
1. Total Calories: 25 kcal/kg BW, in general 1 ml of
water/kcal (matching energy input with expenditure
remains controversial)
2. Glucose: 30 – 70% of total calories/day (2 – 5 g
glucose/kg BW/day)
3. Fat: 15 – 30% of total calories/day
4. Protein: 15 – 20% of the total calories/day (estimated
1.2 – 1.5 g/kg BW/day)
Micronutrients:
Potassium, Magnesium, Zinc, and Phosphate.
Route of Administration
Enteral route:
Preferred for NS, preserve gut integrity,
barrier, immune functions, and reduce
infection.
Early enteral nutrition (as soon as
possible after resuscitation) is preferred.
ENTERAL NUTRITION
1. In the early years EN focused predominantly
on delivering adequate calories and protein
2. As more was learned from altered
metabolism (renal, hepatic, diabetic, organ
dysfunction ) : New formulas emerged
 Specialized formulation
IMMUNE ENHANCE FORMULA /
IMMUNO-NUTRIENT
1. Contain spesific substrates aimed at cellular
target
2. Intended to enhance immune cellularity and
function  minimized inflammation
3. Potential to alter outcomes : infections
(morbidity)
HOW TO PRACTICE :
1. Which specific patients subgroups will
benefit from “ These formula “ compared
with standard formula
2. Therapeutic dose for that benefit ?
3. When should the intervention be initiated
for that benefit and for how long ?
NUTRITION IN CLINICAL
PRACTICE : EVIDENCE BASE
1. Critically ill patient / sepsis : These
patients were extremely heterogenous
 “ Varied in results “
2. Elective surgical gastrointestinal cancer
patients were more homogenous
Immunonutrients
• Greater effects
– Glutamine
– Arginine
– -3 Fatty Acids
• Lesser effects
– Nucleotides
– Vitamins A, C, E
– Zinc
– Taurine
Arginine:
• Conditionally essential AA (growth,
illness, metabolic stress)
• Exogenous source of arginine appears
necessary for optimal immune system
functioning (T lymphocyte)
• Improve N – balance
• “Modulate vascular flow patterns via
nitric oxide”
Glutamine:
• Conditionally essential AA:
– stress conditions
– fuel for rapidly replicating cells: immune cells, GI
mucosa cells

Understanding CD4 and CD8 cells
• CD4 cells and CD8 cells are types of
immune system white blood cells:
– CD4 cells (also called helper T-cells)
coordinate immune activity and direct other
immune cells
– CD8 killer T cells attack cancerous cells and
cells infected with viruses
– (CD8 suppressor T cells inhibit immune
activity once an invader is conquered)

Recommendations US Summit on Immuneenhancing enteral therapy 2001; benefits from
immunonutrition include:
1. Patients undergoing major elective
gastrointestinal (GI) surgery, especially
malnourished patients
2. Patients with blunt and penetrating torso
trauma
3. Malnourished patients undergoing surgery for
head and neck cancer
4. Patients with severe head injury
5. Burn patients
6. Ventilator – dependent non septic patients at
risk for infection
Practical Strategies
• Adequate IEF Nutrition content (glutamine,
arginine, ω-3 Fatty Acid) and volume (arginine > 12 g/L)
• Duration of giving IEF > 3 days ( 5 – 10
days)
• Nasogastric feeding (every 4 – 6 hours,
gastric residual  150 – 200 ml)
• Feeding goals: 25 kcal/kg BW,  800
ml.day
• NEO-MUNE Formula: 5 – 8 sachet/day
