I decided to donate platelets for the first time. If you've never donated, it's usually a two arm process - one to remove the whole blood and another to replace the blood after the platelets have been spun out. So the tech - a nappy head - tries to put a needle in my left arm and after several sticks, finally succeeds (I had told her the veins on my left arm were deep & often collapsed but she went at it like a crack addict taking his first hit). She then moves to my right arm aaaand I sneeze, which moves the needle already inserted. Nappy decides I'm a "candidate" for the one arm procedure & moves me to another bed. One arm takes a little longer since you're now pulling and replacing from the same vein. I'm just about finished with the procedure and I tell the nappy head that my arm hurts. She looks and the arm is swollen - with blood. Apparently, when she put the needle in, she nicked the vein so that as the blood is recirculating back into the vein, it's actually leaking out. Nappy told me that a lot of blood had leaked out and the bruising "probably" was going to spread the length of my arm. An hour ago, my arm looked like this: It now looks like this: It's spread a little bit. There's still a lump right above the bend of my elbow, which nappy said is where the blood all pooled, so as that starts to break up, it's going to get worse. If I give platelets again, I want a white tech.
