IV Solutions
Now let's consider the types of fluids you will find in the IV bags. Some of these solutions may be found in either large or small IV bags.
First, there are saline solutions. These fluids contain a specific percentage of the electrolytes sodium (Na+) and chloride (Cl-). The common types of plain saline solutions are:
-
Sodium chloride 0.45%
- Sodium chloride 0.9%
Normal Saline and Half Normal Saline IV Bags |
We commonly refer to these solutions in several ways:
|
Some solutions contain fluid, electrolytes and some calories in the form of carbohydrates. The carbohydrate used is dextrose, which will be abbreviated as "D". Fluid types and the abbreviations used for each inlcude:
|
D5NS IV Bag |
D5W IV Bag |
There are also solutions which provide fluid replacement and some calories (dextrose) but no electrolytes (no Na or Cl).

Some solutions have more electrolytes than the simple saline solutions. The electrolytes potassium (K) and calcium (Ca) may be added. Two types of such solutions include:
- Ringer's solution, simply called "Ringer's"
- Lactated Ringer's solution, abbreviated LRS.
