What is the maximum fat dose per kilogram of body weight in parenteral nutrition?

• A. No more than 1 g/kg
• B. No more than 0.5 g/kg
• C. No more than 2 g/kg
• D. No more than 1.5 g/kg

Answer: (A)

Providing fat in parenteral nutrition involves a balance between delivering essential fatty acids and energy without causing lipid overload. The practical upper limit for adults is about 1 g of fat per kilogram of body weight per day. Sticking to this ceiling helps prevent complications from excessive lipid administration, such as hypertriglyceridemia, fatty liver (hepatic steatosis), cholestasis, and impaired immune function. Doses lower than this may be insufficient to meet essential fatty acid requirements in some patients, while doses above it increase the risk of the lipid-related complications just mentioned. So, no more than 1 g/kg/day is the best guideline for maximum fat dosing.
