Color Coded IV Needle Gauges - page 2

I need help remember what color corresponds to a particular needle gauge. My patient had a pink cathether but it didn't have a gauge size labeled. What are all the colors and sizes? Helpful... Read More

    Unfortunately 27 gauges are also gray but I seriously doubt anybody would confuse one with a 16!

    Hey, you can fit the orange 16g into the mnemonic because underneath the gray dirt is "orange" magma in the earth's mantle! I guess just go from the core of the earth all the way up to the sun, LOL!

    We don't use 16g or 24g, but I remember the others by thinking I'd turn green if somebody came at me with an 18g, twenty TWO rhymes with blue, and pink is just the other one LOL

    When my husband has triple bypass sx the anesthesiologist put in two 14g IVs. I almost died!! They looked like garden hoses!!
    OMG! If someone came at me with 14g I would run for the hills.

    Here is a guide:

    There is a color coding system for peripheral venous cannulae:

    22G Blue
    20G Pink
    18G Green
    17G White
    16G Grey
    (14G Brown)

    However, there is also a DIFFERENT color coding system for hypodermic needles, namely:

    27G (Outer diameter is 0.4 mm) Grey
    25G (Outer diameter is 0.5 mm) Orange
    23G (Outer diameter is 0.6 mm) Blue
    21G (Outer diameter is 0.8 mm) Green

    I hope this clarifies the issue.

    i think it vary based on the institution as well as the manufacturer, but at my hospital:
    [color="deepskyblue"]blue rhymes with 22g
    green rhymes with 18g
    pink - 20g (the other one lol)

    the only other one i've seen (and only once) is gray, which is 16g.
