Pearls and fun nuggets

1. Lactated Ringer’s is often preferred over Normal Saline 👌  Ringer’s lactate solution has a lower rate of acidosis as compared with normal saline.[1][4]

2. Ringer’s saline solution was invented in the early 1880s 📜 It was invented by Sydney Ringer,[4] a British physician and physiologist. Ringer was studying the beating of an isolated frog heart outside of the body. He hoped to identify the substances in blood that would allow the isolated heart to beat normally for a time.[18]

3. It became “lactated” ringers In the 1930s ☝ the original Ringer’s saline solution was further modified by American pediatrician Alexis Hartmann for the purpose of treating acidosis. Hartmann added lactate, which mitigates changes in pH by acting as a buffer for acid. Thus the solution became known as “Ringer’s lactate solution” or “Hartmann’s solution”.[4][19]
