General anaesthesia refers to a induced state of sleep with an absence of pain and sensation throughout the body. There are 3 key components to general anaesthesia:
- Muscle relaxation
- Pain relief
Your anaesthetist will meet you and place a plastic cannula in your arm. Medicine will be given through this cannula which will put you to sleep. Anaesthetic gases will then be administered to maintain this state of sleep. Your anaesthetic doctor will be with you throughout the operation, carefully assessing and monitoring your heart rate, blood pressure and breathing. At the end of the operation you will be gently woken in comfortable and relaxed state.
Your highly trained anesthetist will be with you every step of the way. Modern general anaesthesia is very very safe, however all operations and all anesthetic procedures have some risk associated with them. These risks depend upon many factors, including the type of surgery and your medical condition.
