An acquaintance of mine with Down's syndrome, no less, couldn't do a gastroscopy to investigate a quality-of-life issue that was assumed to be benign, due to this. Boggles my mind, honestly.
General anesthesia might be over-used, but some healthcare systems go too far in the other direction too.
You can also go to other doctors in a socialized one, if their treatment (style) does not fit your cause.
Also, in my experience there's lots of choice in most socialized health care systems.
I had a gastroscopy in Austria, the Doctor asked me if I'd like a general anesthesia or rather a local, nerve blocker - mostly to avoid the gag reflex.
He said that it may not be as pleasant without the anesthesia, but I still opted for it and am really glad I did. While it really was not pleasant, I was up and going again in about half an hour.
It's just "how it's done". Just like the US has it's own unique methods that seem odd to Europe.
Don't it just turn on the chlorine tap on a neuron to open so that the voltage is now much lower and it will inhibit the signaling ???.
It is the natural mechanism of a neuron so I don't see what side effects there could be - it is like pulling a jumper wire from one pin to another pin on a board to get a voltage right.
Benzodiazepines are considerate anxiolytics whereas propofol would be considered moderate sedation. Neither of these require airway control (intubation) because people tend to keep breathing on their own and we really would much prefer that.
With general anesthesia, you cannot protect your airway whatsoever and will need some form of airway control via either endotracheal intubation or LMA.
The patient is aware, can breathe on their own, and can respond to basic commands, but is relaxed, with a much higher pain threshold, and has no memory of the event.
That sync with your experience, doc?
For the overwhelming majority of patients, you simply fall asleep, avoid discomfort, and then go on with your life. Weighing that against the risks of a traumatic or very painful wakeful experience is not trivial.
What I'm trying to argue is that "one step away from death" is a state we too-often in American medicine treat as hum-drum.
If you're having a medical procedure and the physician mentions general anesthesia, always ask if IV sedation works as an alternative.
