Your nurse might give you a carbohydrate rich drink to have the evening before the operation. The drink gives you energy and can help you to recover more quickly.
Just before the operation you:
- stop eating for about 6 hours beforehand, but you can usually drink clear fluids up to 2 hours before the operation – your doctor or nurse will give you exact instructions about this
- change into a hospital gown
- take off jewellery – you can usually keep your wedding ring on
- take off any make up, including nail varnish
- remove contact lenses if you have them
- put on compression stockings (if you need them) – these help prevent blood clots
Your surgeon may use a marker pen to draw on your skin to show the area of the operation.
For some operations, you might need to have part of your body shaved. This is usually done when you are under anaesthetic in the operating room. Your nurse may do this on the ward.
Medicine to empty the bowel
Your surgeon might need your bowel to be completely empty before surgery. This usually means following a special diet for a few days and taking medicines to completely clear the bowel. Your team will give you instructions.
Medicine to relax
Occasionally, your nurse might give you a tablet or an injection to help you relax. This will be about an hour before you go to the operating theatre. This makes your mouth feel dry but you can rinse your mouth with water to keep it moist.
Your nurse and a porter take you to theatre on a trolley if you have had medicine to help you relax. Usually, you will walk down to the operating theatre (if you have not taken medicine to make you relax). Your nurse will go to the operating theatre with you.
Having an anaesthetic
You have an
All the doctors and nurses wear theatre gowns, hats and masks. This reduces your chance of getting an infection.
The anaesthetist puts a small tube into a vein in your arm (cannula) so that you can have any fluids and medicines you need during the operation.
There are different types of anaesthetics. You may have a:
- local anaesthetic – the anaesthetist injects anaesthetic to numb the part of your body being operated on
- regional anaesthetic – the anaesthetist numbs a large area or part of your body, for example, using an injection into your spine (epidural) to numb your lower body
- general anaesthetic – the anaesthetist gives you drugs that make you unconscious, so you aren't aware of anything during the operation
With local and regional anaesthetics, you may have a drug to help you relax as well as the injection to numb the area. You are awake during the operation but might feel sleepy. Your doctor may suggest a regional anaesthetic if you are not fit enough for a general anaesthetic.
You have a general anaesthetic as an injection of drugs into a vein in your arm. This makes you go into a deep sleep and when you wake up, the operation is over.
You might have a combination of anaesthetics for some types of surgery. For example, you might have a general anaesthetic and a regional anaesthetic (epidural) to help with pain relief after the operation.
