What is a general anaesthetic?
A general anaesthetic is a combination of drugs that causes deep sleep. It is used for operations or medical procedures as it causes a loss of sensation and makes you unaware of what is happening to you.
How is general anaesthetic administered?
Most people are sent to sleep by injecting the drugs through a drip (small tube) into a vein. It takes about 30 seconds to work. For some people, it may be more appropriate to go to sleep by breathing an anaesthetic gas through a face mask. This also takes about 30 seconds to work.
Are there any alternatives to a general anaesthetic?
Other forms of anaesthetic include injections near the area of surgery (local anaesthesia) or injections of local anaesthetic near major nerves or the spinal cord (regional, epidural or spinal anaesthesia). Local anaesthetics will numb the area to be operated on but you will be awake or under sedation for the operation.
Is a general anaesthetic safe?
A general anaesthetic is safe for most people. Your anaesthetist may need to do some tests before the operation to assess how safe a general anaesthetic is for you. These may include an ECG, blood tests or lung-function tests.
What complications can happen?
- Sickness or feeling sick
- Sore throat
- Muscle and back pains
- Dental damage
- Loss or change of hearing
- Eye injury
- Nerve injury
- Heart attack
- Chest infection and other breathing problems
How will my anaesthetist know that I am really asleep?
The anaesthetist continuously monitors the amount of anaesthetic in your body and, above certain levels, nobody has ever been shown to be awake.
How soon will I recover?
A general anaesthetic can affect your judgement and reactions for the first 24 hours after you have woken up. If you are fit and maintain a healthy weight, you are more likely to do well after having a general anaesthetic.
