When I was in the hospital for my gall bladder a few years back, I learned there is a such thing as an "IV specialist" in this case a nurse who does almost exclusively that I guess. They had trouble with my veins due to dehydration plus they've always been small... so they called her and waited for her...
Whenever I have a blood draw (a1cs and other bloodwork) the phlebologists use "butterfly needles" due to my "weird" veins. The surgical center didn't have them for anything AFAIK... At least, I listened to the preop instructions (no eating or drinking before the operation due to anesthesia [oh, the stories that I've overheard about other patients, including one who takes/took the same diabetes medications as I do!])
I'm definitely wearing reading glasses when reading anything including on the computer screen, EVEN though I blow up the magnification.
