Blown vein in blood draw


So I actually have quite a bit of experience with blood draws but today was a first for me. I blew someone's vein while drawing blood! This happened after I already had vacutainer full of blood.

i pulled out needle when I saw lump and applied pressure for a while. I sent away blood to lab. I am wondering whether this would affect results at all?

im wondering if there are any tricks to avoid this? I'm thinking I left tourniquet on too long on his little veins.

It happens to everyone. No worries. It sounds as if you handled it well.

Happened to me for the first time recently after hundreds of blood draws. Shouldn't effect the results since you had already collected the sample.

It happens. I blew someone's vein the other day, but at least I got the blood-she was a very difficult draw!

Sometimes it might cause hemolysis if any of the blood went into the vacutainer after the "blow." This will cause a falsely elevated K+. But the lab is good at detecting that and will order a recollect.
