Dextran 70 is a glucose polymer used medically as a colloid, injected intravenously, to increase the plasma volume in hypovolemia. The number comes from its average molecular weight of approximately 70,000. Dextrans, which principally have 1,6-glucosidic linkages, have molecular weights ranging from 20,000 to 200,000.
Dextran is similar in application to hydroxyethyl starch, but is more antigenic. Neither has oxygen-carrying capacity, or contributes to the ability of blood to coagulate.
It is cheaper than hydroxyethyl starch and albumin injection.
