Why do we use filter for TPN?

Central venous catheters (CVCs) and parenteral nutrition (TPN) are major risk factors. In-line filters in the intravenous (IV) administration sets prevent the infusion of particles, which may reduce infectious complications.

Why are lipids important in TPN?

Lipid provides two major advantages for total parenteral nutrition (TPN). First, it provides essential fatty acids, thus avoiding essential fatty acid deficiency, and secondly, it is a useful energy source, providing 9 kcal/g.

Does TPN require a filter?

The use of an in-line, 1.2-micron filter is recommended for the infusion of total parenteral nutrition (TPN), also known as 3-in-1 or all-in-one [AIO], and intravenous fat emulsions (IVFE) infused alone through a separate IV line.

Do you use a filter for lipids?

Filtering is required of some IV lipid products available on the market in the United States. For lipid injectable emulsion (Clinolipid; Baxter, Deerfield, IL) and IVFE Intralipid, a 1.2 micron or larger filter is required.

What is the difference between TPN and PPN?

The difference between TPN and PPN is that TPN is a long-term therapy by which patients are receiving nutrition despite having a high risk of infection. On the other hand, PPN is a supplement that is used when the patient has other sources of nutrition. The word TPN stands for Total parenteral nutrition.

Can TPN and lipids run together?

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. Agency policy may allow amino acids and lipid emulsions to be infused together above the filters.

Can you run lipids through a peripheral IV?

Due to their low osmolarity (20% lipid emulsions: 270–345 mosm/l; 350–410 mosm/kg), lipid emulsions can be infused via peripheral venous access if needed. The infusion of lipid emulsions presents no independent, clinically relevant risk of infection (IV).

What is a 0.22 micron filter used for?

The 0.22-micron filter is one of the smallest used in patient care, and removes bacteria. There are not currently filters that remove viruses. Not all intravenous medications should be administered through a filter, and others may require filters of a specific size.

Do you need to filter out TPN with lipids?

TPN requires a filter to stop any large particles or crystals from entering the patient. MVI, Trace, Insulin etc will not be filtered out. TPN with lipids should be filtered.

What kind of filter do you use for TPN?

If the TPN and lipids are mixed together ( also called a 3 in 1 preparation) then you use a 1.2 micron filter…if you run them separately use the .22 micron in-line or add-on filter for the TPN…..piggyback the Lipids distal to the filter….and yes lipids will eventually occlude the .22 micron filter.

Can You filter lipids with a 1.2 micron filter?

Lipids can not be filtered with this size filter and are piggybacked below the filter. When a total nutritent admixture or 3-in-1 solution is used, the lipids dictate that a 1.2 micron filter be used. There is a chance of the fat emulsion to crack when infused this way, posing a greater risk of fat emboli. This filter would stop this.

What is the purpose of a lipid filter?

You can also run the Lipids seperately and in that case no filter will be needed. I prefer to piggyback it so I have the other lumen (s) available to me. The purpose of the filter is to capture and trap particulate matter,air and bacteria. The micron size tells you the smallest size particle the filter will retain.
