Mechanism of action

HES is a glucose polymer derivative that remains in the intravascular space longer than crystalloid solutions, providing sustained volume expansion and improved hemodynamic stability. It is used as a plasma volume expander in acute blood loss and perioperative settings to restore circulating blood volume and maintain tissue perfusion without the need for immediate blood transfusion.
