Same here, and the veins in my hands stand out like cord wood. I guess procedure MUST be followed.I kept saying, in the politest tone of voice I could manage, "You know, I have good veins in my wrists," which I do, even dehydrated, and she kept ignoring me while I bit my tongue and didn't scream. Finally she looked up, saw my face, went white as a sheet, and said, "I'm going to go get an expert to do this." Sure enough, the charge nurse came in, took one look at my arms, and put the IV in my wrist. It was a great relief, both because it meant I could get hydrated again and because it meant they could put some Demerol in the IV (I was in the middle of an acute gall bladder attack at the time). And the invisibility of the veins in my elbows doesn't change with my weight; at this time I was 5'4" tall and weighed about 100 pounds soaking wet. I've never been able to understand why people prefer to take the pulse at the elbow; it's extremely difficult to find in my elbow, but actually visible in my wrist.
