We don't have different colored caps, but here are my thoughts:
I think it would work if it were to be standardized, and make everyone use it. That way, you wouldn't have ppl saying red is "this",,,, no no red is "that", no blue is "this".... get the idea? Have everyone be on the same page.
BUT, what if you run out of red caps, then are forced to use a blue cap because you have to use something. This could be confusing (for some).
At my hospital, we use different color tape to color code the lines
. It is up to each nurse if she/he wants to color code, but it sure makes it easier when you have 6 drips going
. Ex: you put green tape on your pump with bicarb, label BICARB on the green tape on the pump, and then tape around the line (usually 2 places on the line and near the injection port). This way, everything is color coded and very easy to quickly see what is going where. OF COURSE, it is still the nurses responsibility to trace from the pt to the pump and verify what is in that line before she pushes anything.
I have worked where they color code the lines and where they do not. Color coding makes life a lot easier (but then again, I am a bit anal
and like stuff to be organized and I think this helps).
