IV fluids are specially formulated liquids that are injected into a vein to prevent or treat dehydration. They are used in people of all ages who are sick, injured, dehydrated from exercise or heat, or undergoing surgery. Intravenous rehydration is a simple, safe and common procedure with a low risk of complications.

What are the types of IV fluids?

There are different kinds of IV fluids. Your healthcare provider will decide which type is right for you, depending on why you need them.

Crystalloid solutions: These are the most common types of IV fluid. They contain small dissolved molecules that pass easily from the bloodstream into tissues and cells. Examples include normal saline, which is salt in water, and D5W, which is dextrose (sugar) in water. Another example is lactated Ringer’s, which contains sodium, chloride, potassium, calcium and lactate. It’s used for aggressive fluid replacement.

Colloids: These are large molecules that can’t easily pass through cell membranes and are more likely to stay in the blood vessels. Examples include albumin and hetastarch.

 Isotonic: Isotonic solutions are solutions having equal osmotic pressures.

 Hypotonic: Hypotonic solutions are solutions having lower osmotic pressures. 

Hypertonic: Hypertonic solutions are solutions having comparatively higher osmotic pressures.
