RESUMEN
Objective To observe the effect of different doses of fat emulsion on blood lipid and liver function in critically ill premature infants. Methods 40 babies were randomly divided into 4 groups,receiving fat emulsion 0,1,2,3 g?kg~(-1)?d~(-1) for 5 days respectively. The blood levels of cholesterol and triglyceride and the serum biochemical indexes relative to liver functions were measured before and after the period of 5 days. Results Blood lipid and serum ?-GT levels did not change remarkably in 1 or 2 g?kg~(-1)?d~(-1) group, but increased significantly in 3 g?kg~(-1)?d~(-1) group. Serum bilirubin levels decreased in all groups, but it was significantly higher in the group of 3 g?kg~(-1) ?d~(-1) than the others. Conclusion It is suggested that the blood lipid level would increase with 3g?kg~(-1)?d~(-1) of fat emulsion used in critically ill premature infants and that the use of fat emulsion would retard the falling of serum bilirubin level when used in newborn infants with byperbilirubinemia.
