What Is Lactated Ringer's Solution?

Lactated Ringer's solution is an isotonic intravenous solution, similar in composition to Hartmann's solution. Abbreviated as "LR" or "RL". Ringer's solution without lactic acid. The solution was invented by British physiologist Sydney Ringer.

Each liter of lactated Ringer's solution contains:

Used to treat blood loss caused by trauma, surgery, burns, etc., and to promote urine production in patients with renal failure. The acidosis produced in both cases is balanced by the metabolites of lactic acid in the liver.

Dosage is calculated from estimated fluid loss. When replenishing body fluids, the general dosage is 20-30 milliliters per kilogram of body weight per hour. In terms of electrolyte concentration, lactated Ringer's solution contains too much sodium and insufficient potassium, so it should not be used for long-term infusion, especially for children.

Lactic acid Ringer's solution is a liquid that is closer to the internal environment of amphibians. In experiments, it can be used to extend the frog heart's beating time in vitro and maintain the physiological activities of other amphibians in vitro.
