Description and Uses

Hetastarch, another nonproteinaceous colloid, is a complex mixture of ethoxylated amylopectins ranging in molecular weight from 10 to 1,000 kDa (average molecular weight, ~450 kDa). When infused as a 6% solution, hetastarch approximates the activity of human albumin. The larger molecular weights, however, increase its intravascular residence time as well as its plasma expansion effects relative to albumin.
Hetastarch is synthetically produced, so it is degraded more slowly and is less antigenic than other colloids. Despite these advantages, hetastarch is quite expensive and also has no oxygen-carrying capacity.
