no tourniquet
Don't tie your tourniquet too tight on patients with big ropes...you'll risk blowing the vein.
When you don't succeed the first time, try sometime different the second time...change arms, try a smaller cath, move the tourniquet higher or lower...
just a thought- when I was a student, I read an article about IV starts which recommended with elderly/frail people that a tourniquet NOT be used. I have had several successes this way. My most proud stick was a 97-yo teeny oncology pt, no tourniquet and it went in the first time. I have used this method on other pts also. My instructor was leery but it worked.
