Dextran 40 Sodium Chloride Injection

This product is a blood volume expander. After intravenous injection, it can increase plasma colloidal osmotic pressure, absorb extravascular water into the systemic circulation to increase blood volume, and increase and maintain blood pressure. Its blood volume expansion effect is weaker and shorter than that of dextran 70, but its effect on improving microcirculation is stronger than that of dextran 70. It can disaggregate already aggregated red blood cells and platelets, reduce blood viscosity, improve microcirculation, and prevent thrombosis. In addition, it also has an osmotic diuretic effect. This product has strong antigenicity. Since there are bacteria that produce this product in the normal intestine, some patients will have allergic reactions even after the first injection of this product. Mainly skin and mucous membrane allergic reactions.
