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.
Beside this, is a 16 or 18 gauge needle bigger?
18 Gauge: This size allows you to do most tasks that the 16 gauge can, but it large and more painful to the patient. This size is better for patients with smaller veins.
