Why Lactated Ringers in Pregnancy?

Lactated Ringer's is recommended by the American College of Surgeons as the initial fluid for resuscitation. Normal saline is a secondary choice because of the potential for hyperchloremic acidosis. *Also contains K⁺ (4 mEq); Ca²⁺ (3 mEq); and lactate (28 mEq), which is converted to HCO₃^-.

Why is lactated Ringer's used in labor and delivery?

When IV fluids are medically necessary, the type of solution and the amount infused should be determined on an individual basis (ACOG, 2017). Normal saline and Ringer's lactate are isotonic solutions, meaning that they allow water to flow freely at a cellular level, without causing cells to swell or shrink.

Which IV fluid is best for pregnancy?

Insert IV line and give fluids slowly (normal saline or Ringer's lactate) – 1 litre in 6-8 hours (3 ml/minute) B9.
