The present invention relates to an infusion preparation which is provided with a plurality of mutually-separated chambers so that glucose, an amino acid, an electrolyte and a fat emulsion are separately stored. The infusion preparation comprises: a first chamber filled with a first infusion fluid comprising dextrose monohydrate; a second chamber filled with a second infusion fluid comprising an amino acid and an electrolyte; and a third chamber filled with a third infusion fluid comprising a fat emulsion, lecithin and sodium oleate, wherein the separation of some or all of the first to third infusion fluids is released right before the infusion preparation is used so that the first to third infusion fluids are all mixed together. According to the present invention, an infusion preparation may be provided which comprises an optimal ratio of a saturated fatty acid, a monounsaturated fatty acid and a polyunsaturated fatty acid, by means of strengthening the amount of olive oil and fish oil.
