Are you dead under anesthesia?

“It’s a reversible coma, but it’s nevertheless a coma,” says Emery Brown, a professor of anesthesiology at Harvard Medical School and coauthor of the paper. General anesthesia before major surgery dips brain activity (as measured by electroencephalogram, or EEG) down to levels akin to brain-stem death.

Some patients may be more resistant to the effects of anesthetics than others; factors such as younger age, obesity, tobacco smoking, or long-term use of certain drugs (alcohol, opiates, or amphetamines) may increase the anesthetic dose needed to produce unconsciousness but this is often used as an excuse for poor …

Does awake surgery hurt?

As it sounds, when people undergo awake brain surgery — also known as an awake craniotomy — they are awake, at least for part of it.
