Here's mine:
I was working a night shift, which to this day I truly detest. When I got report, I found I had a patient in acute alcohol withdrawal (which in and of itself makes me furious, because there is no excuse for a hospitalized patient to suffer DT's if someone knows what they're doing, but I digress.)
Anyway, back to this unfortunate soul.
Because he was delusional and combative, he was restrained so he couldn't yank his IV out for the 10th time. They had also wrapped his IV site with kerlex as an added precaution...maybe if he couldn't find it he'd leave it alone. He was also being transfused with a couple of units of blood.
When I got there, he was nearly through the first unit, and I was to finish that and hang the next one. Well and good. Or so I thought. I started the second unit, but I had one hell of a time infusing it. I literally forced it in with the help of a pressure bag, and I am not kidding when I say it took a good 6 hours to get that blood in. Meanwhile, the patient was getting more and more agitated, which I attributed to his withdrawal.
Finally, mercifully, the blood was in so I opened up the saline to flush the line. But it wouldn't run. All of a sudden I realized, with absolute horror, what had happened.
I cut off the kerlex covering the IV site hoping against hope I was wrong, but alas, I wasn't. Yes indeed, I had infiltrated a unit of blood. I hadn't even bothered to check the site.
No wonder he was so agitated, it probably hurt like hell.
An hour later my manager showed up, and I told her what happened. She was probably the most easy going person I've ever known, and she told me not to worry about it.
I said "Listen to me, I infused an entire unit into his arm, go look at it." She did, and came out and told me to go home. I expected consequences, but never heard another word about it. But I am here to tell you I learned from that mistake.
