I've had two ablation's myself. After the 2nd one I suffered a stroke. It had no lasting effects I'm aware of, but that's just luck.
Heightened stroke risk is a well know is a side of ablation's. In the week or two after they are done tend to spin off clots, and that's when mine happened. However, to put that risk into perspective, stroke is also a well known side effect of the thing ablation's treat - arrhythmias. Unlike the risk from ablation's, the risk caused by arrhythmias goes on for life, and goes up as they get worse over time - which they almost inevitably do.
In a general anesthesia you can't breath on your own so they stick a tube in your mouth. And it needs a special doctor (anesthesiologist) to perform the general anesthesia.
There was no anestesist (extra doc) present in the procedure, so I assumed it was no general anesthesia. But I dont know. Was it?
I don’t know the distinction between that and “general” anesthesia (they called this general), but I know there are different levels (and there was no need for breathing assistance at that level).
General anesthesia is a big deal both for the patient and for the doctors/hospital.
As an added bonus the doctor can show you anything they find on the screen and answer questions.
It wouldn't have occurred to me at all to ask them to put me under if there's a next time. And according to my SO, I'm rather pain intolerant.
If you're doing a biopsy I can imagine it's something else.
It was very obvious in term of decline, my father had trouble with doing some tasks on his computer (when he never did before having been an early adopter and programming some educational software for schools in the 80s), he no longer could concentrate enough when reading and became more extreme in his politics (he went from voting from the parti socialiste and being mostly center left to being very left wing). He also had less control over his emotions and would sometimes explode in a rage unlike anything he had before.
He himself felt diminished mentally and that greatly bothered him during the last years of his life.
On my side, I've refused general anaesthesia as much as I can because it scares me deeply. When I was a kid, I had an operation under general anaesthesia and I woke up with a very strong asthma attack, completely unable to breathe. Reading this, it does give argument towards my stance to asking for local anaesthesia as much as possible.
