Good luck suing the surgeon. Look at all the botched MM surgeries - I can think of 5 on this forum alone. Results so bad that it could not have possibly been him.
Look at the massive volume of surgeries that these big name clinics do. Even your local bum surgeon typically operates like it's an assembly line: one after the other on the same day. It's mostly wisdom teeth and implants, but hey, even he has to take a piss, have a break. What do you think the interns are there for? Merely to hand him instruments?
A dental nurse who works for max facs told me that once the patient is under, all the pleasantries fly out the window - your head is a football. Not out of malice - it's a business and time is money. You really have no idea what goes on once you're under.
This is very scary.
To prevent actions like this happening and to protect each party I think there should be cameras set to the OR and where ever the patient is while they are under anestesia and passed out.
I have friends who have a camera at their home that are attached to wifi. Through that they can observe things through their phone that go around in their house while they are gone. They can also talk with the person who are there. It quite cheap system even the camera quality is quite good. Less than 50€.
Now when something has gone terribly wrong the doctors never take responsibility of their doings and blame many times that the patient is crazy. I think any good facility should set up a video surveillance like this, thus they show they have nothing to hide and they show that if something wrong happens they can always double check that who did what around the patient while they were drugged out. I can not think any reason why would someone argue against this sort of surveillance. Then there would be no need for blaming eg. the malpractice victim who has all ready hard time coping that they are troll and crazy when they only try to tell online the truth about the horrors they went through in some place.
I think 50€ is not a big investment for the safety that should be the number 1 priority at any facility.
