Dextran 40, sold under the brand name LMD among others, is a type of fluid given by injection into a vein to expand blood volume.[2] Specifically it is used for shock such as that caused by bleeding or burns when blood transfusions are not quickly available.[2] However, it does not carry oxygen.[3]

Side effects may include volume overload, kidney problems, acidosis, allergic reactionss, and poor blood clotting.[2] It is not recommended in severe kidney failure, heart failure, or clotting disorders.[2] Use may interfere with certain blood tests.[2]

Dextran 40 came into medical use in 1961.[4] It is a glucose polymer with a typical molecular weight of 40 kDa.[1][4] It works by pulling fluid from the extravascular space into the blood vessels.[2] It is a non protein based colloid solution.[2][1]

Medical uses

Other uses may include as a starting fluid for extracorporeal circulation.[1] And to decrease the risk of blood clots during certain surgeries.[1]


In adults the first half liter may give given rapidly.[2] In children 5 to 10 mL/kg may be used.[2]
