Well, for what it's worth, EVERYONE has something that registers a mark on their own personal "Ick Stick"
For some, it's feces. Others, vomit, phlegm, "purulent drainage" (lol, won't use short term). Once you've smelled a GI bleed there's just NO losing that from your olfactory memory!
For me, it's ET suctioning. Seriously, I can clean or suction anyone's trach, I'm fine with that particular grossness. But have me stick a tube DOWN someone's throat from the MOUTH, and *I* am gagging.
First patient like that was a 96 year old contractured woman who had to have her secretions suctioned regularly. I'll NEVER EVER forget the look and feel of that thick, slimy, paperlike SHEET of sludge that peeled off the back of her throat and stuck fast to the end of the suction. My eyes were watering and (while I tried to hide it) I was quite literally gagging.
Thankfully, she was in no position to notice or recognize anything
I was doing or feeling.
Worse than the thick papery goop, though, was thick mucousy goop. Supposedly the more exposure, the less sensitivity. That's about the only way. Yay.
I had better stop now!
