Anaesthesia is the absence of pain sensation in either any or all parts of the body. In a general anaesthetic, consciousness is lost and you go to “sleep”. In a local or regional anaesthetic, only a part of your body goes numb e.g. arm or legs.
The drugs used in anaesthesia can affect other body functions, so you will be reassured to know your anaesthetist will be present throughout your entire operation to take care of you.
