在肠胃外营养中除以葡萄糖、果糖等糖类作为非蛋白能源外,尚可应用静脉注射用脂肪乳剂。脂肪乳剂与其他非蛋白能源相比,具有下列特点。 (1)脂肪含热量高,氧化1g脂肪提供9千卡热量,氧化1g葡萄糖或果糖仅提供4千卡热量。因此,在输入较少水份的情况下脂肪乳剂可供给较多的热量,对液体摄取量受限的肠胃外营养患 Divided in the parenteral nutrition glucose, fructose and other carbohydrates as a non-protein energy, still can be applied intravenous fat emulsion. Compared with other non-protein energy fat emulsion, has the following characteristics. (1) Fat has high calorie content and oxidizes 1 g of fat to provide 9 kcal, oxidizes 1 g of glucose or fructose provides only 4 kcal of calories. Thus, fat emulsions can provide more heat with less water being infused, parenteral nutrition with limited liquid intake
