What Are Some Common Types of Intravenous Fluids?

One type of intravenous fluid is lactated Ringer's solution, according to Drugs.com. Blood and plasma volume expanders are other forms of intravenous fluids, states Boundless, Artificial blood is another common type of intravenous fluid, reports PubMed Central.

Ringer's solution is a sterile solution of sodium chloride, sodium lactate, potassium chloride and calcium chloride, says Drugs.com. It delivers water and electrolytes and reduces the acidity levels in the body. It is delivered as an airtight but flexible container with two ports. One port is attached to the intravenous delivery mechanism, while the other allows medication to be added to the container.

Volume expanders add fluid to a circulatory system that has been depleted due to blood loss, says Boundless. Though they don't take the place of blood cells, volume expanders help the remaining red blood cells deliver oxygen. Volume expanders can be crystalloid or colloid. Crystalloids contain mineral salts and other molecules that dissolve in water. Colloids have insoluble molecules such as hydroxyethyl starch or gelatin.

Blood products include red blood cells, whole blood, platelets, mononuclear cells and source leukocytes, says the Red Cross. Granulocytes are also delivered intravenously. These blood products can be frozen, washed, irradiated, antigen negative and produced especially for children.

Though artificial blood cannot really replace real blood, it is used to deliver oxygen to the cells and support the platelets in reducing blood loss, claims PubMed Central.
