Usually a large bore needle is used in emergent situations, such as an 18-gauge or 16-gauge. The old standard was to use a catheter no smaller than a 20-gauge. Research shows that a 22-gauge needles will suffice without significant hemolysis (blood cell rupture). Remember that the bigger the gauge number, the smaller the diameter.
