Question
Hello.

There has been some press in the past few years (in the U.S.) about people being aware of their surroundings while under anesthesia. For example, they can hear what's being said and can feel the actual surgery. Since they are paralyzed, they can't give any signs of being aware.

My question is- how does this happen and how can it be prevented? I'll admit, I'm scheduled for surgery in 2 weeks, and I'm a little freaked out!!

Thank you in advance for your response.

This is something that we are spending a lot of time trying to prevent. In reality it effects only a small number of patients each year, however it is a serious issue and one that I have corresponded with many people about over the years on AllExperts.

Not every operation requires the patient to be given drugs that paralyse them. I therefore teach my trainees to avoid these drugs whenever possible. This means that if someone was aware they would be able to move and let us know.

There is no current device that is 'failsafe' in preventing this problem - though we are getting closer. The main problem is that everyone is different and metabolises and reacts to the drugs we use in slightly different ways. This means what is a reasonable dose for one person might not be enough for another or vice versa.

Finally let me say that most of the cases that do occur have some particular reason for the problem happening. Analysis of these is making anaesthesia safer.

I wish you all the best with your operation.
