Study Notes

Composition and Function of Intravenous Lipid Emulsions

Intravenous lipid emulsions resemble endogenous triglycerides in their composition.
They provide essential fatty acids, such as linoleic and alpha-linolenic acid, which cannot be produced by the human body.
Lipid emulsions are the most important source of essential fatty acids and provide energy to individuals receiving parenteral nutrition, accounting for 4 kcal/g.

Benefits of Intravenous Lipid Emulsions

Polyunsaturated fatty acids in lipid emulsions can improve the net effects of retrieved eggs and regulators in assisted reproduction cycles.
Lipid emulsions have been shown to ameliorate metabolic and immunologic disturbances associated with parenteral nutrition deficiency.
Volume control of IVFE infusion can be utilized effectively with concurrent parenteral replacement of dextrose and amino acids.

History of Intravenous Fat Emulsions

The initial administration of intravenous fat emulsion dates back to the early 1960s.
Significant advances in lipid emulsion technology were made in the 1950s to 1970s, including the preparation of smaller, more homogeneous lipid emulsion particles and the addition of emulsifying agents.

Clinical Evidence and Use

Parenteral nutrition with intravenous fat emulsion has been widely used since 1961 and has been a life-saving therapy.
Intravenous fat emulsion has been shown to reverse local anesthetic-induced cardiotoxicity and is used as a component of total parenteral nutrition (TPN).

Bioavailability and Metabolism

The effectiveness of EPA and DHA after intravenous administration depends on plasma concentrations and accumulation indices in different tissues.
Intravenous administration of fatty acids is more effective than oral administration due to faster administration and counteraction of hypoalbuminemia.
