This can make the use of one more suitable than the other depending on the situation. Being isotonic means the fluids have the same osmotic pressure as blood.
Osmotic pressure is a measurement of the balance of solutes such as sodium, calcium, and chloride to solvents for example, water. Instead, the solution will increase the fluid volume in your body. This can be a beneficial effect to avoid fluid overload. The body metabolizes this component to something called bicarbonate. Also, normal saline has a higher chloride content.
This can sometimes cause renal vasoconstriction, affecting blood flow to the kidneys. Pharmacies instead mix normal saline with the following IV solutions:. The extra calcium could bind with the preservatives added to blood by blood banks for storage. This potentially increases the risk of blood clots. According to B. Some of the reasons why a person may get this IV solution include:.
It can therefore be used to wash out a wound. It can also be used during surgery to irrigate the bladder or a surgical site. This helps to wash away bacteria or make a surgical site easier to see. When the solution goes into the vein, it goes inside cells as well as outside. If a person with any of these conditions requires LR or saline, a medical professional will monitor them closely for signs of hypervolemia.
In previous years, some medical professionals expressed concern over using LR during blood transfusions. The reason for this concern was that some anticoagulant, or blood-thinning, medications contain citrate, while LR contains high levels of calcium.
Mixing citrate with calcium can cause blood clotting and obstruct an IV line. However, a person can receive anticoagulant medications and LR at the same time, as long as a medical professional delivers each treatment through a separate IV line. The other IV solution is saline. The two solutions differ in their chemical makeup and their effects on the body.
Unlike saline, LR has an alkalizing effect on the body. It also remains inside the body for a shorter period. LR is safe for most people. However, it can cause allergic reactions, such as discoloration, itchiness, and swelling at the injection site. People with certain medical conditions — such as congestive heart failure, liver failure, or chronic kidney disease — have an increased risk of swelling when receiving any type of IV fluid. Anyone who has any of these conditions will receive close monitoring to ensure that their fluid levels remain within the normal range.

If you've ever had surgery or been sick or injured enough to require hospitalization, there's a good chance you were given something called lactated Ringer's solution. This oddly-named fluid is delivered via IV intravenously, which means into a vein to treat dehydration, deliver medication, and restore fluid balance following an injury. Ringer's solution was developed in the lates by a British physician named Sydney Ringer for keeping organs hydrated during live animal research.
In the s, a physician named Alexis Hartmann modified Ringer's original formula by adding lactate, which he found lowered the risk of acidosis the abnormal buildup of acid in the blood. Other variations of Ringer's solution exist, such as one that includes acetate which may be better for people with liver disease since lactate tends to increase as the liver function decreases. It is more beneficial than saline solution in that it doesn't remain in the body for as long and so is less likely to cause fluid overload.
The addition of lactate reduces acidity as it is converted by the body into bicarbonate, a base element that helps regulate the body's pH balance. Acidosis commonly occurs when the liquid portion of the blood is too low—a condition called hypovolemia. Lactated Ringer's solution also is ideal for people with sepsis , kidney failure , or respiratory acidosis whose acid-base balance is characteristically thrown off.
Lactated Ringer's solution can also be used for non-intravenous purposes, such as flushing wounds and irrigating tissues during open surgery.
