Indications and Clinical Use

SmofKabiven Electrolyte Free[Amino acids with electrolytes, dextrose and lipid injectable emulsion (5.1 % / 12.7 % / 3.8 %); w/v] is indicated for intravenous infusion into a central vein as parenteral nutrition for adult patients when oral or enteral nutrition is impossible, insufficient or contraindicated.

SmofKabiven Electrolyte Free are three-component products. Each component is located in a separate chamber. Before use, the seals between the chambers must be broken to mix the components.


SmofKabiven Electrolyte Free can be used in adults including geriatrics (see Warning and Precautions section).


SmofKabiven Electrolyte Free is contraindicated in patients with:

  • Hypersensitivity to fish-, egg-, soybean- or peanut protein or to any of the active ingredients or excipients
  • Severe hyperlipidemia
  • Severe liver insufficiency
  • Severe blood coagulation disorders
  • Congenital errors of amino acid metabolism
  • Severe renal insufficiency without access to hemofiltration or dialysis
  • Acute shock
  • Uncontrolled hyperglycemia
  • General contraindications to infusion therapy: acute pulmonary edema, hyperhydration, and decompensated cardiac insufficiency
  • Hemophagocytoic syndrome
  • Unstable conditions (e.g. severe post-traumatic conditions, uncompensated diabetes mellitus, acute myocardial infarction, stroke, embolism, metabolic acidosis, severe sepsis, hypotonic dehydration, and hyperosomolar coma)

Warnings and Precautions


The infusion must be stopped immediately if any signs or symptoms of allergic reactions (such as fever, shivering, sweating, headache, skin rashes, or dyspnea) develop.

SmofKabiven Electrolyte Free [Amino acids, dextrose and lipid injectable emulsion (5.1 % / 12.7 % / 3.8 %); w/v] should be infused with caution in conditions of impaired lipid metabolism, which may occur in patients with renal failure, diabetes mellitus, pancreatitis, impaired liver function, hypothyroidism, and sepsis.

To avoid risks associated with too rapid delivery, it is recommended to use a continuous and well-controlled infusion, if possible a volumetric pump.

The amount of individual electrolytes to be added is determined by the clinical condition of the patient and by frequent monitoring of serum levels.

Parenteral nutrition should be given with caution in metabolic acidosis, cellular hypoxia and increased serum osmolarity.

Parenteral nutrition infusion may be accompanied by increased urinary excretion of the trace elements, in particular copper and zinc. This should be considered in the dosing of trace elements, especially during long-term parenteral nutrition.

In malnourished patients, initiation of parenteral nutrition can precipitate fluid shifts resulting in pulmonary edema and congestive heart failure as well as a decrease in the serum concentration of potassium, phosphate, magnesium, and water soluble vitamins. These changes can occur within 24 to 48 hours. Therefore, careful and slow initiation of parenteral nutrition is recommended in this patient group, together with close monitoring and appropriate adjustments of fluid, electrolytes, minerals, and vitamins.

SmofKabiven Electrolyte Free must not be given simultaneously with transfusion blood in the same Y-on-site infusion set due to the risk of pseudoagglutination.

Since an increased risk of infection is associated with the use of any central vein, strict aseptic precautions should be taken to avoid any contamination during catheter insertion and manipulation.

Fat overload syndrome is a rare condition that has been reported with intravenous lipid formulations. A reduced or limited ability to metabolize the lipid contained in SmofKabiven accompanied by prolonged plasma clearance may result in a syndrome characterized by a sudden deterioration in the patient’s condition accompanied by fever, anemia, leukopenia, thrombocytopenia, coagulation disorders, hyperlipidemia, liver fatty infiltration (hepatomegaly), deteriorating liver function, and central nervous system manifestations (e.g. coma).

The cause of the fat overload syndrome is unclear. The syndrome is usually reversible when the infusion of the lipid emulsion is stopped. Although it has been most frequently observed when the recommended lipid dosage was exceeded, cases have also been described where the lipid formulation was administered according to instructions.


Fluid status should be closely monitored in patients with pulmonary edema or heart failure.

Endocrine and Metabolism

In patients with hyperglycemia, administration of exogenous insulin might be necessary SmofKabiven should be given with caution in conditions of impaired amino acid metabolism and of impaired lipid metabolism, which may occur in patients with renal failure, diabetes mellitus, pancreatitis, impaired liver function, hypothyroidism, and sepsis.


High levels of lipids in plasma may interfere with some laboratory blood tests, e.g. hemoglobin.


This intravenous emulsion contains soybean oil, fish oil and egg phospholipids which may rarely cause allergic reactions. Allergic cross reaction has been observed between soybean and peanut oil.

If a hypersensitivity reaction occurs (signs or symptoms of anaphylactic reaction such as fever, shivering, sweating, headache, skin rash, or dyspnoea) infusion of the emulsion must be stopped immediately and the appropriate treatment and supportive measures should be undertaken until the conditions have been resolved.


Use with caution in patients with renal insufficiency. Intake of electrolytes such as phosphate and potassium should be carefully controlled to prevent e.g. hyperphosphatemia and hyperkalemia.

Fluid and electrolyte status should be closely monitored in these patients.

Special Populations

Pregnant Women

There are no data available on exposure of SmofKabiven Electrolyte Free in pregnant women. There are no studies available on reproductive toxicity in animals. Parenteral nutrition may become necessary during pregnancy. Then SmofKabiven Electrolyte Free should only be given to pregnant women after physicians have carefully considered the potential risks and benefits.

Nursing Women

There are no data available on exposure of SmofKabiven Electrolyte Free in breast-feeding women. Parenteral nutrition may become necessary during lactation. SmofKabiven Electrolyte Free should only be given to breast-feeding women after physicians have carefully considered the potential risks and benefits.


No studies have been performed in the pediatric population.


Metabolism of SmofKabiven Electrolyte Free does not appear to be affected by advanced age.

Monitoring and Laboratory Tests

Fluid and electrolyte balance, serum osmolarity, serum triglycerides, acid/base balance, blood glucose (dextrose), liver and kidney function, blood count, including platelets, and coagulation parameters should be monitored throughout treatment. Daily monitoring is recommended during initiation of parenteral nutrition and until the patient and laboratory measurements are stable, followed by regular monitoring as required. Blood cell count and coagulation should be monitored when lipids are given for an extended period.

In patients with renal insufficiency, the phosphate and potassium intake should be carefully controlled to prevent hyperphosphatemia and hyperkalaemia.

Individual capacity to eliminate lipids should be monitored according to standard practice. This is generally done by checking serum triglyceride levels which should not exceed 4 mmol/L during infusion. An overdose may lead to fat overload syndrome, see Adverse Reactions.

The lipid content of SmofKabiven Electrolyte Free may interfere with certain laboratory measurements (e.g. bilirubin, lactate dehydrogenase, oxygen saturation, hemoglobin) if blood is sampled before lipids have been adequately cleared from the bloodstream. Lipids are cleared after a lipid-free interval of 5 to 6 hours in most patients.

In case these side effects occur during the infusion of SmofKabiven Electrolyte Free [Amino acids with electrolytes, dextrose and lipid injectable emulsion (5.1 % / 12.7 % / 3.8 %); w/v], the infusion should be stopped or, if necessary, continued at a reduced dosage.

Adverse Drug Reactions observed during administration of emulsion for intravenous nutrition in general, including SMOFlipid, and reported spontaneously from post-marketing experience are displayed in Table 4.

Drug Interactions

Drug-Drug Interactions

Some medicinal products, like insulin, may interfere with the body’s lipase system. This kind of interaction seems, however, to be of limited clinical importance.

Intravenous heparin infused in clinical doses and some non-steroidal anti-inflammatory drugs (NSAIDs) cause a transient increase in lipoprotein lipase release into the circulation. This may initially result in increased plasma lipolysis, followed by a transient decrease in triglyceride clearance.

Table 5 - Potential Drug-Drug Interactions
Proper name Ref Effect Clinical comment
Heparin, NSAIDs T A possible transient decrease in triglyceride clearance These findings are based on basic research and not reported as adverse events in clinical practice.
Insulin T May interfere with the body’s lipase system These findings are based on basic research and not reported as adverse events in clinical practice.
Coumarin derivatives T May decrease anticoagulant effect Soybean oil has a natural content of vitamin K1. However, the content is so low in SmofKabiven that it is not expected to impair the therapeutic effects of coumarin derivatives on coagulation.

Drug-Food Interactions

No SmofKabiven Electrolyte-food interaction studies have been performed.

Drug-Herb Interactions

No SmofKabiven Electrolyte-herb interactions studies have been performed.

Drug-Laboratory Interactions

High plasma levels of lipids may interfere with some laboratory blood tests, e.g. hemoglobin.

Dosage and Administration

Dosing Considerations

The patient’s ability to eliminate lipids as well as metabolize nitrogen and glucose, and the nutritional requirements should govern the dosage and infusion rate. The dose should be individualized with regard to the patient’s clinical condition and body weight (bw).

The nitrogen requirements for maintenance of body protein mass depend on the patient’s condition (e.g. nutritional state and degree of catabolic stress or anabolism).

The requirements are 0.6 - 0.9 g amino acids/kg bw/day (0.10 - 0.15 g nitrogen/kg bw/day) in the normal nutritional state or in conditions with mild catabolic stress. In patients with moderate to high metabolic stress with or without malnutrition, the requirements are in the range of 0.9 1.6 g amino acids/kg bw/day (0.15 - 0.25 g nitrogen/kg bw/day). In some very special conditions (e.g. burns or marked anabolism) the nitrogen need may be even higher.

Recommended Dose and Dosage Adjustment


The dosage range of 13 – 31 mL SmofKabiven Electrolyte Free/kg bw/day corresponds to 0.6 - 1.6 g amino acids/kg bw/day (0.10 - 0.25 g nitrogen/kg bw/day) and 14 - 35 kcal/kg bw/day of total energy (12-27 kcal/kg bw/day of non-protein energy). This covers the needs of the majority of patients. In obese patients the dose should be based on the estimated ideal weight.

Infusion Rate

The maximum infusion rate for dextrose (glucose) is 0.25 g/kg bw/h, for amino acid 0.10 g/kg bw/h, and for lipids 0.15 g/kg bw/h.

For SmofKabiven Electrolyte Free the infusion rate should not exceed 2.0 mL/kg bw/h providing 0.25 g dextrose (glucose), 0.10 g amino acids, and 0.08 g lipids/kg bw/h. The recommended infusion period is 14 - 24 hours.

Maximum Daily Dose

The recommended maximum daily dose of SmofKabiven Electrolyte Free is 35 mL/kg bw/day providing 1.8 g amino acids/kg bw/day (corresponding to 0.28 g nitrogen/kg bw/day), 4.5 g dextrose (glucose)/kg bw/day, 1.33 g lipids/kg bw/day and a total energy of 39 kcal/kg bw/day (corresponding to 31 kcal/kg bw/day of non-protein energy).

The four different package sizes of SmofKabiven Electrolyte Free are intended for patients with basal, moderately increased or high nutritional requirements. To provide total parenteral nutrition, trace elements, vitamins, and electrolytes should be added to SmofKabiven Electrolyte Free according to the patient’s individual requirements.


SmofKabiven Electrolyte Free[Amino acids with electrolytes, dextrose and lipid injectable emulsion (5.1 % / 12.7 % / 3.8 %); w/v] is intended for infusion into a central vein once the vertical and horizontal seals have been broken and compartments thoroughly mixed. (See Special Handling Instructions)

SmofKabiven Electrolyte Free may only be mixed with other medicinal products for which compatibility has been documented (see Special Handling Instructions).

Ceftriaxone must not be administered simultaneously with intravenous calcium containing solutions through the same infusion line (e.g. via Y-site) because of the risk of precipitation of ceftriaxone-calcium salt. If the same infusion line is used for sequential administration, the line must be thoroughly flushed with a compatible fluid between infusions.


If symptoms of overdose of lipids or amino acids occur, the infusion should be reduced or discontinued. There is no specific antidote for overdose. Emergency procedures should be general supportive measures, with particular attention to respiratory and cardiovascular systems. Close biochemical monitoring would be essential and specific abnormalities treated appropriately.

If hyperglycemia occurs, it should be treated according to the clinical situation either by appropriate insulin administration and/or adjustment of the infusion rate.

Additionally, overdose might cause fluid overload, electrolyte imbalances, and serum hyperosmolarity.

In rare serious cases, renal replacement therapy may be considered.

Action and Clinical Pharmacology

Mechanism of Action

The primary goal of parenteral nutrition is to provide adequate calories and protein to supply required nutrients and to prevent malnutrition with its associated complications when the patient is unable to receive adequate oral or enteral nutrition. SmofKabiven Electrolyte Free provides the three macronutrients: glucose (as dextrose), amino acids, and lipids consisting of saturated fatty acids especially MCT (medium-chain triglycerides), monounsaturated and polyunsaturated fatty acids (essential fatty acids).

Amino acids provide the basic substrates for protein synthesis in all tissues and are metabolic precursors and intermediates of numerous other molecules and biochemical pathways. Amino acids provided in excess of requirements are not stored but are used as metabolic fuel. The alpha amino group is removed and the remaining carbon skeleton is transformed into acetyl CoA, acetoacetyl CoA, pyruvate, alpha-ketoglutarate, succinate fumarate, or oxaloacetate.

An adequate supply of amino acids is required for protein synthesis and reduced protein breakdown, especially in metabolic situations with increased endogenous protein degradation, as in many acute or chronic catabolic diseases.

Dextrose (glucose) is the primary source of energy for cells. All body cells have the capacity to metabolize dextrose (glucose) into pyruvate (glycolysis), which may then be oxidized in mitochondria when present, or converted anaerobically to lactate. Channels for entrance of dextrose into body cells may be activated by insulin or, as in red blood cells, be independent from insulin. Dextrose can be stored in the liver as glycogen under the influence of insulin, and converted back as required.

Lipids should be an integral part of a parenteral nutrition regimen. Fatty acids are the most calorically dense form of energy available (9 kilocalories per gram vs approx. 4 kilocalories per gram glucose and amino acids). Fatty acids may be oxidized orincorporated in cell membranes and act as precursors for prostaglandins, leukotrienes, thromboxanes, other bioactive molecules as regulators of gene expression, and as modulators of hormonal functions. Fatty acids also have a role in the propagation of nerve impulses, and in absorption of fat soluble vitamins from the diet.

The two essential fatty acids (EFA) linoleic acid, an omega-6 polyunsaturated fatty acid (PUFA) and α-linolenic acid, an omega-3 polyunsaturated fatty acid, have to be provided intravenously if the gut is dysfunctional. Long-chain omega-3 fatty acids especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from fish oil contribute directly to higher levels of eicosanoids without the need of elongation from α-linolenic acid, showing beneficial effects on cell membranes and inflammatory processes.

Stored fat becomes the major fuel source once the carbohydrate store (glycogen) has been depleted. Long-chain fatty acids bypass portal circulation and are presented to the periphery and stored in adipose tissue until needed. Responding to a decrease in insulin levels, long-chain FAs are released and are used by muscle tissue for energy production.


The lipid emulsion of SmofKabiven Electrolyte Free is composed of SMOFlipid and has a particle size and biological properties similar to those of endogenous chylomicrons. The different constituents of SMOFlipid, i.e. soybean oil, medium-chain triglycerides, olive oil, and fish oil have their own pharmacodynamic properties. The energy content (9 kcal/g) is the same for all fatty acids.

Soybean oil has a high content of essential fatty acids (linoleic acid and alpha linolenic acid). The omega-6 fatty acid linoleic acid is the most abundant. The ratio of omega-6/omega-3 fatty acid in SMOFlipid 20% is approximately 2.5:1.

Medium-chain fatty acids are rapidly oxidized.

Olive oil mainly provides energy in the form of mono-unsaturated fatty acids, which are much less prone to peroxidation than the corresponding amount of poly-unsaturated fatty acids.

Fish oil is characterized by a high content of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). DHA is an important structural component of cell membranes, whereas EPA is a precursor of eicosanoids as prostaglandins, thromboxanes and leukotrienes, thereby modulating inflammation.

Vitamin E protects unsaturated fatty acids against lipid peroxidation.

The amino acids are utilized for tissue protein synthesis and any surplus is channeled to a number of metabolic pathways. Studies have shown a thermogenic effect of amino acid infusion.

Dextrose contributes to maintain or replete the normal nutritional status through provision of energy.


The ingredients of SmofKabiven Electrolyte Free (amino acids, with electrolytes, lipids, dextrose) are distributed, metabolized and eliminated in the same manner as if they had been administered individually. The bioavailability of intravenously infused substances such as SmofKabiven is 100%.

The individual triglycerides in SmofKabiven Electrolyte Free have different clearance rates. Clearance is fastest for medium chain triglycerides (MCT). Fish oil in a mixture with LCT has the same clearance rate as LCT alone.

The principal pharmacokinetic property of the infused amino acids and electrolytes is that the intravenously infused amino acids directly reach the systemic circulation.

Depending on the nutritional state, dextrose can be rapidly metabolized to carbon dioxide and water, stored in the liver and muscles as glycogen, or converted to fat in the adipose tissue.

Special Populations and Conditions

Pharmacokinetic data have not been obtained in special patient populations or conditions.


Exploratory studies with the lipid compound have been conducted but confirmatory pivotal studies have not been provided. No pediatric studies with SmofKabiven Electrolyte Free have been performed.


The metabolism of SmofKabiven Electrolyte Free does not appear to be affected in elderly.


There are no differences between the genders regarding the metabolism of SmofKabiven Electrolyte Free.

Hepatic Insufficiency

Overdosing of energy regardless of origin (glucose or lipids) may cause steatosis and result in further hepatic impairment.

Renal Insufficiency

As SmofKabiven Electrolyte Free add to circulatory volume, it is important to have an adequate renal function. In case of renal failure, it is recommended to have access to renal replacement therapy due to the risk of fluid overload.

Product Container

The container consists of a multi-chamber inner bag and an overwrap. The inner bag is partitioned into three chambers to keep the components separated until the bag is activated by the user. An oxygen absorber is placed between the inner bag and the overwrap. The inner bag is made of a multilayer polymer film that consists of poly(propylene-co-ethylene), synthetic rubber poly[styrene-block-(butylene-co-ethylene)] (SEBS) and synthetic rubber poly(styrene-block-isoprene) (SIS). The infusion and additive ports are made of polypropylene and synthetic rubber poly[styrene-block-(butylene-co-ethylene)] (SEBS) equipped with synthetic polyisoprene (latex-free) stoppers. The blind port, which is only used during manufacturing, is made of polypropylene equipped with a synthetic polyisoprene (latex-free) stopper.
