You will need to fast for several hours before having a general anaesthetic. It is important that you follow the fasting instructions - otherwise you may not be treated on the day of your appointment
General anaesthetic is given by an anaesthetist.
What is an anaesthetist?
An anaesthetist is a doctor with specialist training who is responsible for giving you your anaesthetic and caring for you while you are drowsy or asleep. Anaesthetic drugs are injected into a vein, usually in the back of your hand, through a cannula (a very fine plastic tube).
The anaesthetist stays with you throughout your procedure to make sure you are safe and well. Once your treatment is finished the anaesthetic drugs wear off very quickly.
Where do I go to sleep?
You will go to sleep in the operating theatre and someone is with you at all times.
Where do I wake up?
After your treatment, you normally wake up or come around in the recovery area. Our specially trained staff look after you and when they are satisfied that you have recovered from your anaesthetic you can move from the recovery area. We will encourage you to be up and about as soon as possible after the treatment.
Are there any rules I must follow?
YES, and it is very important that you follow instructions or you may not be able to have the anaesthetic you planned. The most important rule is to stop eating and drinking for a period of time before a general anaesthetic.
Eating and drinking before a general anaesthetic or conscious sedation
6 hours before your appointment:
Stop eating. You must not have milk, fizzy drinks or juice. You must not suck sweets either.
6 to 2 hours before your appointment:
You can drink sips of clear liquids (only water, black tea and black coffee without sugar or milk). You can chew gum.
2 hours before your appointment:
Do not eat, drink or chew gum.
It is very important that you follow these instructions about eating and drinking. If you don’t, it may be unsafe for us to treat you and your procedure may be cancelled, or you may not be able to have the anaesthetic you wanted. You can eat and drink normally after your treatment.
What about alcohol?
Do not drink alcohol for 24 hours before your appointment time.
You must not drive yourself home after a general anaesthetic. If you intend to drive the anaesthetist may refuse to treat you. We recommend that you don't drive any vehicle for 24 hours. Driving during that time may mean prosecution under Section 4 of the Road Traffic Act 1988 relating to driving under the influence of drugs.
We strongly recommend that someone accompanies you home and stays with you for 24 hours after your treatment. This should be an adult who can look after you. You should not operate machinery for 24 hours after your general anaesthetic.
What about drugs and medication?
Any drugs can affect your reaction to the anaesthetic. If you are taking medication please tell us what you are taking and the last time you took it. If you are taking recreational drugs please be open and honest with us as they can also affect your anaesthetic. Anything you tell us is kept confidential.
