I am working as a phlebotomist and donor processor at a plasma center at the moment, and just real quick, here is a great story of my first traumatizing experience.
I went out to the floor to do a set up and stick to help the phlebotomists the other day. (They were backed up.) I went out and did a great set up and stick, then someone asked me to do their stick, I went over and did it and he started flowing fantastically. I documented everything and set the chart down and his machine starts beeping, "No Flow." Beep....Beep. Ok, okay. I take the tape off the needle and push the needle in a little farther and he starts flowing fantastically again. I wait a second and then reach over to grab some new tape.
As I do so I accidentally pull the needle out of his arm and blood starts flowing everywhere! Holy cow! One hand has the needle and I'm holding it away from anyone, and my other is putting pressure on his arm. I can't reach the gauze pads or the machine, and I don't know what to do.
I call for help, and get it all taken care of and get a new needle and re-stick him in the other arm.
In the meantime blood has pooled all over the floor, my shoes, and is all over my lab coat.
Oops, sorry mister.
