Thank you all for your encouraging replies. I have managed to put in a few IVs recently, with around a 70% success rate. Not perfect, but much better than before. Why I "just couldn't" before I still can't figure out, and till this day I can't really identify what went wrong... or went right which bugs me. And yes indeed. 90% of my ICU patients have central lines, port-a-caths, you name it. Those that don't come up from emergency with 18G needles in them already nice and patent.
