由于中链脂肪乳剂的结构、生化特征 ,具有氧化快而完全、较少依赖肉毒碱转运等优点 ,目前已普遍应用于临床营养支持。但是 ,临床上有关中链脂肪乳剂与传统的长链脂肪乳剂在各领域中应用的比较研究却较少 ,而且结果相差很大。本综述通过总结临床上有关中、长链脂肪乳剂的前瞻性随机对照研究资料 ,比较中、长链脂肪乳剂在临床上各种情况下的应用结果 Due to the structure and biochemical characteristics of medium-chain fat emulsion, it has the advantages of fast and complete oxidation and less reliance on carnitine transport, and has been widely used in clinical nutrition support. However, the comparative studies on the application of medium-chain fat emulsion and traditional long-chain fat emulsion in various fields are few in clinical practice, and the results vary greatly. This review summarizes the results of prospective randomized controlled clinical trials of medium and long-chain fat emulsions and compares the results of long-chain fat emulsions in various clinical situations
