Regional anesthesia is an alternative to general anesthesia.
A patient may sometimes choose a particular form of anesthesia, however for certain types of operations medical considerations alone are taken into account.
Regional anesthesia is preferable in certain medical situations: respiratory deficiency, for elderly patients, or in cases of full-term pregnancy.
There are a variety of regional anaesthesias:
Spinal or epidural anesthesia which anesthetises the lower region of the body.
Peripheral nerve block anesthesia.
A nerve can be blocked at its trunk level, for example to anesthetise an entire leg.
A nerve can also be blocked at the level of one of its roots to anesthetise a specific part of the leg.
