Lactated Ringer's injection, also called Ringer's lactate, is a solution of balanced electrolytes, made up to be isotonic in water. It is most commonly administered intravenously, but is also given subcutaneously, principally in veterinary medicine.
As defined by the U.S. Food and Drug Administration, each 100 milliliters contains: Each 100 mL of Lactated Ringer's Injection USP contains:
- Sodium chloride 0.6 g
- Sodium lactate 0.31 g
- Potassium chloride 0.03 g
- Calcium chloride dihydrate USP 0.02 g
- Water for injection to make 100ml
The ideal pH is 6.2, with an acceptable range between 6.0 and 7.5. After dissolving the ingredients, the pH may be adjusted with hydrochloric acid or sodium hydroxide.
In general, it is more physiologic than normal saline, but should not be used in cases where the patient has an excess of one of the ions, especially potassium or lactate.
