Normal saline vs. half-normal saline
Normal saline (0.9% NaCl) has roughly the same salt concentration as blood, which makes it isotonic. It is the most widely used IV fluid in the world and the standard choice for hydration, flushing IV lines and carrying medications.
Half-normal saline (0.45% NaCl) contains half the salt and is hypotonic. It is used for more specific purposes and should be used as directed by a clinician.

A saline bag alone is not enough to start an IV. You will also need an administration set (tubing), an IV catheter, a saline flush and supplies to prep and secure the site. Our complete IV fluid kits include a saline bag plus all 11 other pieces in one box, or you can shop IV supplies individually. New to it? Read how to set up an IV bag at home.
