How do I choose a needle for injection?

The optimal needle length to choose would be 25 mm. For the subcutaneous injection, the needle size should be 1/3 of the tissue, about 10 mm. The correct needle to choose is the 10 mm, to inject the right tissue, to get the right effect of the medicine and reduce the risk of injection site reactions.

What is needle gauge size?

Needle Gauge. The gauge refers to the inner measurement or opening of the needle. Needles are routinely available in a variety of gauge sizes, including 18, 21, 23, and 25 gauge, as shown in the image. The needle gauge becomes a consideration when the vein of the patient is narrow, fragile, or superficial.

Is an 18 or 20 gauge bigger?

The smallest gauge is typically considered something along the lines of a 22 gauge, which is very tiny. Gauges get larger with decreasing number (i.e. a size 00G is massive compared to a 20 gauge). with an 18 gauge. If you want it smaller, ask for a 20 or even 22 gauge when getting pierced.

What is a 16 gauge needle used for?

21-gauge needles are most commonly used for drawing blood for testing purposes, and 16- or 17-gauge needles are most commonly used for blood donation, as the resulting lower pressure is less harmful to red blood cells (it also allows more blood to be collected in a shorter time).

Why are needle gauges backwards?

Beyond international standards, another source of confusion is why wire gauge sizes appear to be backwards of what they should be—as the physical width of the gauge increases the numerical value assigned to it decreases. The explanation goes back to the original process of wire drawing.
