Deaths due to intravascular fat accumulation in the lungs in preterm infants after infusion of intravenous fat emulsion have been reported in the medical literature . Autopsy findings included intravascular fat accumulation in the lungs. Preterm infants and low-birth-weight infants have poor clearance of intravenous lipid emulsion and increased free fatty acid plasma levels following lipid emulsion infusion . Use caution when treating premature and low birth weight infants with intravenous fat emulsion and strictly adhere to the recommended total daily dose and hourly infusion rates. Hourly infusion rate should be as slow as possible in each case and fat should not in any case exceed 1 g fat/kg in four hours.

Uses for fat emulsion

Tell your doctor right away if you or your child have the following symptoms: rapid, shallow breathing, trouble breathing, fast heartbeat, lightheadedness, dizziness, or fainting, nausea or vomiting, rash or itching skin, or a fever or chills.
Fat emulsion may increase your risk of developing infections. Avoid being near people who are sick or have infections while you or your child are receiving fat emulsion. Wash your hands often.
