Hi Mary.....re: the little device with a blue light that tells techs where the veins are. When I had my last stress test (nuclear) the techs in the scan room used one of those to locate my veins. I hate to be the bearer of bad news, but it didn't make any difference. Even I could see the veins with it....but apparently you can't tell if it is a GOOD vein....They had to stick me several times even with the light. And then, of course, when they took the iv out I bled all over their machinery due to the Coumadin (I did tell them I was on Coumadin!)
Hopefully they'll come up with something even better!
