Uses of Lactated Ringer's

Updated February 25, 2011

Lactated Ringer’s is a sterile solution that is used to replace fluid lost by the body. It is commonly used for fluid resuscitation, meaning that the patient needs aggressive fluid replacement for their injury or illness. Lactated Ringer’s looks like water, but it contains additives including calcium, potassium, lactate, sodium and chloride.

Lactated Ringer’s is also known as LR, Ringer’s Lactate and Ringer’s.

Why Is it Called Lactated Ringer’s?

In the late 1800s. a physician named Sydney Ringer developed a solution that contained calcium, potassium, sodium and chloride in water. The solution was referred to as “Ringer’s,” after its inventor.

Years later, a physician named Alexis Hartmann determined that adding lactate to the solution made it more suitable for pediatric patients. With the addition of lactate, the solution became known as “Lactated Ringer’s.”

Why Is Lactated Ringer’s Used?

Lactated Ringer’s is typically used to replace lost fluid, blood, or both. Due to the sodium content, it is typically not used as an ongoing fluid replacement, but instead is frequently used when large volumes of fluid must be given, known as fluid resuscitation.

Severe burns, trauma, significant blood loss, and severe fluid loss (caused by dehydration, surgery or other problems) are just some of the cases in which Lactated Ringer's is given.

Small amounts of Lactated Ringer’s may be given as a maintenance IV, providing necessary fluids when a patient is unable to drink enough fluid to support their normal body functions.

How Is Lactated Ringer’s Given?

Lactated Ringer’s is given intravenously (through an IV), directly into the bloodstream.
