Does Anesthesia take years off your life?

How does anesthesia knock you out so fast?

New research by Hudetz and his colleagues now suggests that anesthesia somehow disrupts information connections in the mind and perhaps inactivates two regions at the back of the brain. Here’s how it works: Think of each bit of information coming into the brain as the side of a die.

How likely is it to die under anesthesia?

The risk of dying in the operating theatre under anaesthetic is extremely small. For a healthy person having planned surgery, around 1 person may die for every 100,000 general anaesthetics given. Brain damage as a result of having an anaesthetic is so rare that the risk has not been put into numbers.

What are the odds of not waking up from anesthesia?

Is going under anesthesia like dying?

“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.

Should I be scared of general anesthesia?

While it’s normal to fear the unknown, it is also important to understand the facts—and the fact is that mortality rates associated with general anesthesia are quite low, particularly for cosmetic surgery procedures. Overall, general anesthesia is very safe, and most patients undergo anesthesia with no serious issues.
