右旋糖酐(dextran)又名葡聚糖。它的制剂中有医疗价值的是:中分子右旋糖酐,其平均分子量((?))为7万;低分子右旋糖酐,(?)为4万;小分子右旋糖酐,(?)为2万;微分子右旋糖酐,其(?)在1万以下。国外临床主要用中、低分子右旋糖酐。目前临床上应用右旋糖酐制剂存在的主要问题是:低、小分子右旋糖酐,脉通液及通脉液等,各生产厂的命名及其所标示的平均分子量极不统一,因此常造成临床选择右旋糖酐制剂 Dextran is also called dextran. Its medical value in the preparation is: the molecular dextran, the average molecular weight (?)) Of 70,000; low molecular weight dextran, (?) Of 40,000; small molecule dextran, Dextran, its (?) In 10,000 or less. Foreign clinical main use of low molecular weight dextran. At present, the main problems existing in the clinical application of dextran preparations are: low and small molecules dextran, pulse-through fluid and Tongmai, etc., the name of the manufacturer and its marked average molecular weight is very uniform, it often results in the clinical selection of dextran formulations
