anesthesia
"Had a colonoscopy on Wednesday and endoscopy on Friday. Propofol was used both times. I felt nothing at the injection site as it was being administered, went right out and woke up less groggy than I usually am every morning. No fear of having these procedures done again because the propofol kept me completely out. However, this morning, about 18 hours after the endoscopy, I began to have some trouble breathing. I don't have any known respiratory issues. When this didn't go away in a couple of hours I ended up in the quick care clinic. They didn't find anything. My oxygen saturation was 99% so I was actually breathing. Wondering if this is just a different respiratory manifestation/side effect of this medicine. I would still take it again."
