Hi doctors, can you tell me what is local anesthesia and general anesthesia?

Hi doctors, can you tell me what is local anesthesia and general anesthesia?

General = brain: Local anesthesia involves injecting numbing medication such as Lidocaine into the area to be numbed. The medication baths the nerves and blocks their ability to sense pain.

Is it advisable to pluck all 4 wisdom tooth all at once under local anesthesia! Is there any side effect after that? Please advice. Thanks

Others only want to go through the experience one time and opt to get it all done at once. The latter strategy makes more sense if IV sedation or general anesthesia is used but it is really up to you unless your particular medical or surgical considerations dictate otherwise. ...Read more

Why doesn't local anesthesia spread to the whole body?

Why doesn't local anesthesia spread to the whole body?

"Local" is why: "local" anesthesia does just that-a small dose of a numbing agent is injected near a nerve, that, when in a certain concentration, blocks impulses through that nerve. The result is numbness and weakness in the distribution of that nerve. This resolves as the local anesthetic is 'washed out" by blood and the localized concentration now will decrease-allowing the nerve to work again. ...Read more
