One of my consults this weekend was an unfortunate fellow in ICU who'd recently had heart surgery. For whatever reason they'd decided to leave his chest cavity open for a few days, in case they had to go back in urgently.
So I went in the room. As expected, the guy was sedated and intubated. I checked his pupils and reflexes, the usual neurology stuff.
Being curious, I couldn't help looking into his partially open chest cavity, where, under surgical-sterile plastic sheeting, I could see his heart beating.
A nurse in the room came over and offered me a Junior Mint.
