(Unfortunately, it was completely unnecessary, but whatever, I'll take it...)
We had a middle-aged guy come in with severe scrotal swelling and pain--it was so bad that he couldn't walk or even close his legs. If anyone even came near him, he would start crying and screaming "please don't touch me! Please!" He was a diabetic and on dialysis. And unfortunately, there was a really specific smell coming from his area--probably Fournier's gangrene.
I gave him a ton of pain meds but nothing was even touching his pain, and we needed to do a CT of his pelvis to see how bad it was--and to examine him. So the docs decided to do a sort of conscious sedation with ketamine. I've used ketamine on kids with no problem, but sometimes adults have an "emergence reaction" when it's wearing off--they can hallucinate and get a little nutso, so they have to be watched very closely.
I got him to the CT scanner on a portable monitor, gave him the meds, and we got the scan. Everything went well (except for the fact that the CT and manual exam pretty much confirmed gangrene).
When he started to wake up, he was relatively calm; a little moaning, a little thrashing, but mostly ok. When he was a little more awake, he kept looking at me and saying, "Miss? I'm so sorry, I'm so sorry!" I would ask him what for and he would say, "I didn't do anything nasty to you did I? I'm so sorry! Tell me if I did! Tell me the truth! I'm sorry, I didn't mean it..." I kept reassuring him that all was well.
Hours later when he was pretty back to normal, I went in to see him and asked how he was feeling. He told me he didn't really like the drugs we gave him. "They gave me weird dreams," he said. "Really?" I said.
"Yes," he replied, blushing and averting his eyes. I wonder what he dreamed?
