ringer's solution

A nurse hangs a bag of Ringer's solution for an intravenous drip.

Definition

Noun: * A physiological saline solution: "Ringer's solution" is a sterile aqueous solution containing specific salts—primarily sodium chloride, potassium chloride, and calcium chloride—in proportions that make it isotonic with the fluids of animal tissues. It is used in medicine and biological research.

Usage
  • Medical Therapy: Used to correct dehydration and restore electrolyte balance, often administered intravenously.
    • The patient was given Ringer's solution to treat severe dehydration.
  • Laboratory Research: Serves as a physiological medium to keep tissues or organs alive and functional outside the body () during experiments.
    • The isolated frog heart continued to beat when perfused with Ringer's solution.
Advanced Usage
  • "Lactated Ringer's solution": A common variant that also contains sodium lactate, which the body metabolizes to bicarbonate, making it useful for treating acidosis.
    • Lactated Ringer's solution is often preferred for fluid resuscitation after blood loss.
Variants and Related Words
  • Ringer's lactate: Another name for Lactated Ringer's solution.
  • Physiological saline / Normal saline: A simpler, isotonic salt solution (typically 0.9% sodium chloride). While related and used for similar purposes, it lacks the potassium and calcium ions found in Ringer's solution.
  • Isotonic solution: The general category of solutions that have the same osmotic pressure as bodily fluids.
Synonyms
  • Balanced salt solution
  • Physiological salt solution
Notes on Meaning
  • The term is named after the British physiologist Sydney Ringer, who developed it.
  • It is a specific formulation, not a generic term for any intravenous fluid. Its key characteristic is being a balanced electrolyte solution that mimics the ionic composition of extracellular fluid.
