Lactic acid is a chemical compound that plays a role in several biochemical processes. It is a hydroxy carboxylic acid. It was first isolated in 1780 by the Swedish chemist Carl Wilhelm Scheele. In medicine, lactate is one of the main components of lactated Ringer's solution and Hartmann's solution. These intravenous fluids consist of sodium and potassium cations, with lactate and chloride anions, in solution with distilled water in concentration so as to be isotonic compared to human blood. It is most commonly used for fluid resuscitation after blood loss due to trauma, surgery, or a burn injury.
