To prevent essential fatty acid deficiency in PN, what is the minimum fat emulsion intake (long-chain fatty acids) per day for an adequately fed infant?

• A. 0.2-0.4 g/kg/day
• B. 0.5-1.0 g/kg/day
• C. 1.1-1.5 g/kg/day
• D. 1.8-2.0 g/kg/day

Answer: (B)

Essential fatty acids cannot be made by the body and must come from the fat component of parenteral nutrition. In infants, providing enough long-chain fatty acids daily is crucial to prevent essential fatty acid deficiency, which can impair skin integrity, growth, and immune function. The minimum fat emulsion intake for adequately fed infants is about 0.5 to 1.0 g per kg per day. This range ensures there are enough linoleic and alpha-linolenic acids to maintain normal skin barrier and physiological functions. Doses below this threshold raise the risk of EFAD, while higher fat amounts (1.1–1.5 g/kg/day or 1.8–2.0 g/kg/day) are used for growth and energy needs beyond preventing deficiency. For a practical sense, a 3 kg infant would receive roughly 1.5–3.0 g of fat per day, which translates to about 7.5–15 mL of a typical 20% lipid emulsion daily.
