Answer

Isotonic Crystalloids

Isotonic sodium chloride (normal saline [NS]) and lactated Ringer (LR) are isotonic crystalloids, the standard intravenous (IV) fluids used for initial volume resuscitation. They expand the intravascular and interstitial fluid spaces. Typically, about 30% of administered isotonic fluid stays intravascular; therefore, large quantities may be required to maintain adequate circulating volume.

Both fluids are isotonic and have equivalent volume restorative properties. While some differences exist between metabolic changes observed with the administration of large quantities of either fluid, for practical purposes and in most situations, the differences are clinically irrelevant. No demonstrable difference in hemodynamic effect, morbidity, or mortality exists between resuscitation with either NS or LR.

Normal saline (NS, 0.9% NaCl)

NS restores interstitial and intravascular volume. It is used in initial volume resuscitation.

Lactated Ringer

LR restores interstitial and intravascular volume. It is used in initial volume resuscitation.
