Iv fat emulsion infusion9/26/2023 The etiology of PNALD is multifactorial however, intravenously administered phytosterols (plant sterols) contained in plant-derived lipid emulsions, including Intralipid, have been associated with development of PNALD. Parenteral nutrition-associated liver disease (PNALD), also referred to as intestinal failure- associated liver disease (IFALD), can present as cholestasis or hepatic steatosis, and may progress to steatohepatitis with fibrosis and cirrhosis (possibly leading to chronic hepatic failure). Risk of Parenteral Nutrition-Associated Liver Disease Parenteral Nutrition-Associated Liver Disease and Other Hepatobiliary Disorders The lipemia must clear between daily infusions. The infant's ability to eliminate the infused fat from the circulation must be carefully monitored (such as serum triglycerides and/or plasma free fatty acid levels). Premature and small for gestational age infants have poor clearance of intravenous fat emulsion and increased free fatty acid plasma levels following fat emulsion infusion therefore, serious consideration must be given to administration of less than the maximum recommended doses in these patients in order to decrease the likelihood of intravenous fat overload. Strict adherence to the recommended total daily dose is mandatory hourly infusion rate should be as slow as possible in each case and should not in any case exceed 1 g fat/kg in four hours. Treatment of premature and low birth weight infants with intravenous fat emulsion must be based upon careful benefit-risk assessment. The container is overwrapped to provide protection from the physical environment and to provide an additional moisture barrier when necessary.ĭeaths in preterm infants after infusion of intravenous fat emulsion have been reported in the medical literature 2.Īutopsy findings included intravascular fat accumulation in the lungs. The container-emulsion unit is a closed system and is not dependent upon entry of external air during administration. This product is not made with natural rubber latex. The container is nontoxic and biologically inert. The container does not contain DEHP (di(2-ethylhexyl) phthalate) or PVC. It contains no plasticizers and exhibits virtually no leachables. The film is polypropylene based comprising three co-extruded layers. The primary plastic container (Biofine TM) is made from multilayered film specifically designed for parenteral nutrition drug products. The phospholipids present contribute 47 milligrams or approximately 1.5 mmol of phosphorus per 100 mL of the emulsion. The total caloric value, including fat, phospholipid and glycerin, is 2.0 kcal per mL of Intralipid 20%. Intralipid 20% (A 20% Intravenous Fat Emulsion) has an osmolality of approximately 350 mOsmol/kg water (which represents 260 mOsmoL/L of emulsion) and contains emulsified fat particles of approximately 0.5micron size. Glycerin is chemically designated C 3H 8O 3 and is a clear colorless, hygroscopic syrupy liquid. R 3 is primarily either the choline or ethanolamine ester of phosphoric acid. These phospholipids have the following general structure:Ĭontain saturated and unsaturated fatty acids that abound in neutral fats. Purified egg phosphatides are a mixture of naturally occurring phospholipids which are isolated from the egg yolk. These fatty acids have the following chemical and structural formulas: The major component fatty acids are linoleic acid (44-62%), oleic acid (19-30%), palmitic acid (7-14%), α-linolenic acid (4-11%) and stearic acid (1.4-5.5%) 1. Where are saturated and unsaturated fatty acid residues.
