Is anaesthesia safe? Modern anaesthesia has become a very safe procedure, considerably safer than travelling in your car. |

Types of anaesthesia and your choice When you need an operation there is often a choice of what sort of anaesthetic is needed to enable the surgeon to perform the operation. |
 |
Local anaesthesia This is the simplest form of anaesthesia. |
 |
A general anaesthetic General anaesthesia consists of three parts: narcosis, analgesia and muscle relaxation. |
 |
Conscious sedation This is a very light form of anaesthesia where the patient does not even lose consciousness. |
 |
Epidural and spinal anaesthesia Local anaesthetic applied to the space around the spinal cord (an epidural) or injected into the fluid surrounding the spinal cord (a spinal) will anaesthetise a large area of the lower body depending on how much is injected and where it is injected. |
