[Effect of fat emulsion (intralipid) on essential fatty acid deficiency during total parenteral nutrition in pediatric patients. Part 1. Experimental study].

Experimental studies were performed to confirm the effect of TPN with and without fat emulsion, Intralipid, on fat metabolism in weanling rats and puppies. Long-term fat-free TPN induced essential fatty acid (EFA) deficiency in weanling rats and the intravenous fat emulsion which accounted for 10% of the total caloric intake could prevent EFA deficiency. In the long-term TPN in growing puppies, fatfree TPN and induced EFA deficiency within two weeks, and Intralipid which accounted for 4% of the total caloric intake (2% as linoleate) satisfied the EFA requirement.
