Description and Uses
Dextrans are glucose polymers produced by bacteria linked in
an α-1,6 chain and having an α-1,3 or α-1,4 branch about every fifth residue. The specific
positioning of the branching varies by the bacterium producing it. The molecular weights of these
chains generally are 40 or 70 kDa (dextran-40 and dextran-70, respectively), and the compounds
work via an osmotic gradient similar to the colloids and hypertonic crystalloid solutions.
Dextrans have a longer intravascular
residence time
than albumin, which limits interstitial edema. As with the crystalloids and other colloids, the dextrans
have no oxygen-carrying capacity. Furthermore, because they are bacterial products, the dextrans
have the potential to be potent antigens and induce anaphylaxis.
