Mechanism of action

Hydroxyethyl starch (HES) is a synthetic colloid derived from amylopectin that remains in the intravascular space longer than crystalloid solutions, providing sustained plasma volume expansion. The 'balanced' formulation typically refers to a solution with electrolyte composition and pH designed to minimize metabolic acidosis and electrolyte disturbances compared to unbalanced HES products. It is used as a blood volume substitute in acute care settings to maintain hemodynamic stability and tissue perfusion.
