Lactated Ringer's solution

Ringer's lactate solution, also known as Ringer-Locke's solution, is a solution that is isotonic with blood. It is intended for intravenous administration in humans, but in veterinary use may also be given subcutaneously. Ringer's lactate solution is grouped with intravenous fluids known as "crystalloids", which include saline and dextrose solutions (compared to the "colloids" which contain larger molecules such as starch or gelatine).
