18 gauge needles are used in medical procedures for their larger size and faster administration of medication or fluids compared to smaller gauge needles. They are typically larger than many commonly used sizes and can be used for a blood infusion or push of IV fluids when time is of the essence.
What is an 18g Needle Used For?
An 18 gauge needle is often used for:
- Blood Infusion: Larger gauge needles are necessary for infusing blood quickly and efficiently.
- Pushing IV Fluids: When there is a need to infuse large volumes of IV fluids quickly, an 18 gauge needle is more suitable.
- CT PE Testing: These needles are commonly used for CT Perfusion testing and other protocols that require a larger-gauged needle.
- Other Procedures: They may also be used for various other medical procedures where a larger gauge needle is preferred.

The Science Behind the Needle Size
The size of a needle is determined by its gauge, which is a letter assigned to the needle by the manufacturer. The higher the gauge number, the larger the needle will be. This system was established so that nurses and other medical professionals could easily distinguish between different sizes of needles and select the appropriate size for the procedure at hand.
The Need for Precision
Precise measurement and handling of medications and fluids is crucial in medical procedures. Needles come in different sizes, and the size of the needle should match the volume of the liquid being infused to avoid blockages or overflow. For example, a 10 µL syringe with a needle gauge of 18 would not be effective for infusing larger volumes of liquid.
The Role of Needles in IV Therapy
Intravenous therapy, or IV therapy, is a method of introducing medications and other fluids directly into a patient's bloodstream. Needles are a critical component of IV therapy, and choosing the right size needle can greatly impact the success of the therapy.
