Lactated Ringer's solution

Lactated Ringer's Solution

Lactated Ringer's solution (pronunciation: lak-tay-ted ring-erz so-loo-shun) is a type of intravenous fluid and electrolyte replenisher. It is used to replace fluids and electrolytes lost in patients with dehydration and metabolic acidosis, or to serve as a buffer when a patient has a low blood pH.

Etymology

The solution is named after Sidney Ringer, a British physician and physiologist who first formulated it in the late 19th century. The term "lactated" refers to the presence of lactate in the solution, which is metabolized in the liver to produce bicarbonate, helping to buffer acidic conditions in the body.

Composition

Lactated Ringer's solution is composed of sodium chloride, potassium chloride, calcium chloride, and sodium lactate. The concentrations of these components are designed to mimic those of the body's own fluids, making it an isotonic solution.

Uses

Lactated Ringer's solution is used in a variety of medical situations. It is commonly used in surgery to replace lost fluids and maintain proper hydration. It is also used in the treatment of burns, trauma, and shock due to its ability to quickly replenish lost fluids and electrolytes.
