The 20-gauge catheter is the most common all-purpose peripheral IV catheter. It is easy to access, has relatively low risk of complications, and can accommodate a variety of medications and fluids. While larger gauges (14 and 16) may be necessary for certain situations, they are more invasive and can cause more discomfort for the patient. A 24-gauge catheter may be too small for certain medications and may be difficult to use in patients with particularly fragile veins.
