Objectives
Calculate basic flow rates for enteral nutrition
considering interruption factors and fluid
needs.
 Calculate parenteral nutrition formulas,
including basic electrolyte considerations.
 Practice the nutrition care process for
enteral/parenteral cases, focusing on new
nutrition diagnosis and intervention
standardized language.

Critical Illness Guidelines 2012: Blood
Glucose Control

promote blood glucose control between 140 to
180 mg per dL in critically ill adult patients
 Tight blood glucose control (80 to 110 mg
per dL) and moderate control < 140 mg per
dL is not associated with
reduced hospital length of stay
Grade II (fair)
days on mechanical ventilation
Grade II (fair)

Critical Illness Guidelines 2012: Blood
Glucose Control
 Tight
blood glucose control (80 to 110 mg per dL)
is not associated with
 infectious complications in surgical (primarily
cardiac) patients
 Grade II (fair)
 cost of medical care
 Grade III (limited
 Tight blood glucose control (80 to 110 mg per dL)
increases risk of hypoglycemia
 Glucose level >180 mg per dL is associated with
increased mortality
 Grade II (fair)

Composition of Solution
3-in-1 Total nutrient admixture (TNA)
 2-in-1
 Lipids infused separately
 Favorable when patients have high protein or
minimal fluid needs and can maintain
euglycemia with addition of modest insulin
dose
 Must use laminar-airflow hood to decrease the
risk of contamination

 Osmolality
Maximum = 900 mOsm
(10 x g pro) + (6 x g CHO) + (.3 x ml fat)

Lipids: Administration
Slow and continuous 24-hour infusion can
improve hepatic reticuloendothelial function
 As opposed to short, < 10 hrs, infusion
 Usually infused over 12 hrs. if infused
separately

Calculation Rules for Lipid
Maximum lipid:
 60% of total kcal
 2.5 g/kg body weight
 2 – 4% of total kcal as linoleic acid to prevent
EFAD
 10% of total kcal as fat meets EFA
 Maximum of 30% lipid for septic patients
 May use > 30% with hyperglycemic or
pulmonary compromised patients
 Usually begin with 1 g lipid/kg/day
15

Calculation Rules for Lipid Cont’d
Intralipid 10%: 1.1 kcal/ml; 11 kcal/g
 Total volume of lipid x .1 = g fat
 Intralipid 20%: 2.0 kcal/ml; 10 kcal/g
 Total volume of lipid x .2 = g fat
 Intralipid 30%: 3.0 kcal/ml; 10 kcal/g
 Total volume of lipid x .3 = g fat

mechanically ventilated adult ICU patients

Calculate 3-in-1 solution/2200 mL



Pt weight @ 55 kg
 requires 2200 kcal; 93 g protein; 2200 ml fluid
Protein: 93 g x 4 kcal/g = 372 kcal
 2200 kcal – 372 kcal = 1828 kcal remaining for fat
& CHO
Lipid: use 1 g/kg/day to start
 55 g x 1 g/kg = 55 g fat
 55 g fat x 10 kcal/g = 550 kcal
 1828 kcal – 550 = 1278 kcal remaining for CHO
Calculate 3-in-1 solution/2000 mL

CHO: 1278 kcal

3.4 kcal/g dextrose
Check maximum CHO
 5 mg x 55 kg x (60 x 24 hr) =
 5 mg

Divide g of each substrate by total volume of
fluid. Multiply x 100 for percent.
 93 g protein x 100 = 4.2% AA

The ASPEN Adult Nutrition Support Core Curriculum, 2nd, 2012:248
Electrolytes: Initial Dose
Generally aim for the middle of the normal
range
 Individualize based on renal function, GI losses,
acid-base balance and medications
 Can use multiple-electrolytes or several single
entity electrolyte solutions
 Dependent on the compatibility of each
electrolyte with the other components in the PN
admixture

Electrolytes: Sodium

Generally use approximately equal amounts of
chloride and acetate (1:1 ratio)
Acetate and chloride also found in AA
solution
 In metabolic acidosis use maximum acetate
and minimum chloride
Acetate is metabolized as bicarbonate
 In metabolic alkalosis use maximum chloride
and minimum acetate
Electrolytes: Sodium
Sodium Goal: 1 – 2 mEq/kg
 Use 1.5 mEq/kg
 1.5 x 70 kg reference man = 105 mEq/day
 2 L (not including IVFE) so 105/2 = 53 mEq/l
Sodium Chloride: 53 mEq
Sodium Acetate: 53 mEq

Electrolytes: Potassium & Phosphorus




Potassium available in chloride, acetate, and phosphate
salts
K: maintenance @ 1 mEq/kg = 70 mEq
 2 L (not including IVFE) so 70/2 = 35 mEq/l
 If serum K is low correct with a separate infusion of K
Phosphorus available as the sodium or potassium salt
Phosphorus: 25 mmol/day
 25 mmol Potassium Phosphate (37 mEq K)
 Remainder of K as KCl: 33 mEq
Electrolytes: Calcium

Ca available as gluconate (preferred form) or
chloride salt
 Gluconate preferred b/c more stable in
solution
Less likely to dissociate and precipitate with
Phosphorus
dose within accepted solubility range and
amino acid pH and concentration
 standard dose: 12 mEq/day
Electrolytes: Magnesium
Mg available as sulfate or chloride salt
 Mg Sulfate is preferred form
 Mg 8 – 20 mEq/day

