Fat Emulsion (Fish Oil Based) – November 2018

Revision in the Administration field of the Fat Emulsion (Fish Oil Based) monograph in the Pediatric and Neonatal Lexi-Drugs database, available online and in mobile apps.

The monograph previously read:

Administration (only portion of field impacted is presented):

IV: Administer by IV infusion via peripheral line or central venous infusion using DEHP-free administration sets and lines. All fat emulsion infusions should be filtered whether part of an admixture or infused separately using a 1.2-micron in-line filter only (ISMP 2016). May be simultaneously infused with amino acid and dextrose mixtures by means of Y-connector located near infusion site (flow rates of each solution should be controlled separately by infusion pumps). When administered with dextrose and amino acids as an admixture, the choice of a central or peripheral infusion depends on the osmolarity of the final infusate (osmolarity ≥900 mOsm/L must be infused through a central vein). Use a vented infusion set when infused from the bottle, avoid multiple connections, do not connect multiple medications in series, and turn off pump before the bottle runs dry.

Rate: Initial rate of infusion should not exceed 0.5 mL/minute for the first 15 to 30 minutes; gradually increase until reaching the required rate after 30 minutes as tolerated. Do not exceed a rate of 1.5 mL/kg/hour. Infusion should be completed within 12 hours when using a Y-connector and within 24 hours when used as part of an admixture.
