In the 1930s, the original solution was further modified by American pediatrician Alexis Hartmann for the purpose of treating acidosis. Hartmann added lactate, which mitigates changes in pH by acting as a buffer for acid. Thus the solution became known as "Ringer's lactate solution" or "Hartmann's solution".
What happens to lactate in Hartmann's?
The lactate disappears into the cells (specifically, a good healthy liver can metabolise amazing amounts of it). Hartmanns is not particularly isoosmotic. Its osmolality (sans lactate) is 248, which is lower than that of the body fluids.
Does Hartmann's contain lactate?
Hartmann's solution contains lactate to generate alkalising HCO3- ions and thus, as an alkalising solution, it does not cause an acidosis. Indeed, it can aid in reducing the risk of acidosis with the administration of large volumes in such patients.
