Transfusion preparation

摘要

The invention addresses the problem of providing a transfusion preparation, wherein: Maillard reactions due to reducing sugars and amino acids do not occur during storage; fat droplet size in the fat emulsion does not increase during storage; there is little danger of the patient developing hyperkalemia or experiencing vascular pain or phlebitis even when only one of the transfusion solutions is given; and multiple kinds of vitamins can be blended stably despite being a two-chambered container preparation. The invention provides a transfusion preparation having two chambers that are separated by a partition that can be opened, wherein: a first chamber transfusion solution containing a sugar and a fat emulsion is accommodated in a first chamber; a second chamber transfusion solution containing amino acids and electrolytes is accommodated in a second chamber; the first chamber transfusion solution contains substantially no potassium and has an osmotic pressure ratio of 2.0-3.0; for the second chamber transfusion solution, the potassium concentration is 40 mEq/L or less and the osmotic pressure ratio is 2.5-3.5; and the potassium concentration of the mixture of the first chamber transfusion solution with the second chamber transfusion solution when the partition is opened is 16 mEq/L or more.
