Had to have a gastroscopy today. I was going to tough it out without sedation (and be able to go home within 20 minutes of the procedure), but they sprayed my throat with some Xylocaine (lidocaine in the US) and it made me retch so hard I was doubled up (I think it was the bitterness of the spray).
So they dosed me with midazolam (versed). Needle went in and I woke up after about 30 minutes. Which is a bit weird, because when they going through the options beforehand they said that the sedation wouldn’t be like a general anaesthesia, I would be aware the whole time. I’ve had lots of general anaesthesias, with various agents (halothane, propofol etc), and on reflection it (the memory loss) feels very similar.
So my questions are:
Was I awake and aware during the procedure, and just failed to form memories or was I out?
Is this a typical experience with midozolam?
If I was out, what then is the difference between “sedation” and “general anaesthesia”?
