I had a colonoscopy last year, and I couldn’t believe how instant they knocked me out. I don’t know if they used Propofol, but they told me “OK were going to put you out” and like in the blink of an eye they said “OK your done” huh? What? You just said you were going to put me out” and they said “We just did it, your finished” It seemed so instant I thought they might have been pulling a scam on me
I know what you mean, it was the same way for me, a couple of years ago I had hip surgery and the last thing I remember was the anesthesiologist telling me that would put me under and wouldn’t feel a thing, I don’t remember her leaving, I don’t remember by wife leaving, the next thing I remember was waking up after what seemed like 5-10 minutes wondering when the surgery was going to happen only to be told, the surgery is over and everything is fine and the doctor would be there soon to check on me,
Same thing happened to me a few years ago. One moment I was wide awake and the next moment they said that they were finished. I couldn’t believe how fast it was.
