| | Regional Anesthesia Scores a Knockout |
 | | In general anesthesia, patients are given a combination of gases and/or drugs in the veins that suppress the pain-sensing central nervous system, essentially putting them into a form of sleep and forgetfulness. |
 | | Regional anesthesia, on the other hand, involves injecting drugs -- either into the spine or into nerves that supply a region of the body such as the chest, abdomen, or pelvis and legs -- that block pain signals from reaching the brain. |
 | | Regional anesthesia may also allow patients to breathe more freely without pain, and cause less strain on the body overall, the authors suggest, although they acknowledge that their study did not have the statistical power to provide a definitive answer. |
