Why are fat emulsions given with TPN?

A lipid emulsion should usually be provided with PN to prevent depletion of essential fatty acids, lower the risk of hyperglycaemia, and prevent hepatic steatosis.

What is in lipid emulsion?

Commercial lipid emulsions in the United States are usually based on soybean oil or soybean and safflower oil. They also include egg yolk phospholipids, glycerin, and water. The presence of soybean and safflower oil means that these solutions are composed primarily of n-6 fatty acids.

What is the use of lipid emulsions?

TPN is not compatible with any other type of IV solution or medication and must be administered by itself. TPN must be administered using an EID (IV pump), and requires special IV filter tubing (see Figure 8.10) for the amino acids and lipid emulsion to reduce the risk of particles entering the patient.

How do you infuse fat emulsion?

How to use Fat Emulsion 20 % Intravenous. This product is given by injection into a vein as directed by your doctor. Before using, check this product visually for particles, oil, or discoloration. If any of these are present, do not use the liquid.

Why is the fat emulsion solution hung higher than the amino acid?

Because of the lower specific gravity, the fat emulsion solution must be hung higher than the amino acid and dextrose solutions to prevent the fat emulsion from backing up into the amino acid and dextrose line. Manufacturer does not recommend use of filters during administration, but 1.2-micron filters have been used.
