How to get prepared for the surgery ?

Preparation for your operation is very important as it reduces the likelihood of difficulties or complications with the anaesthetic.
1. Smoking
If you smoke, you may consider giving up for several
weeks before the operation. The longer you can give up
beforehand, the better.
2. Overweight
If you are very overweight, many of the risks of having
an anaesthetic are increased. Reducing your weight will
help.
3. Loose or broken tooth
If you have loose or broken teeth, or crowns
that are not secure, you may want to visit your dentist
for treatment. The anaesthetist may need to put a tube in
your throat to help you breathe, and if your teeth are not
secure, they may be damaged.
4. Long standing medical problem
If you have a long-standing medical problem such as
diabetes, asthma, hypertension, thyroid problems or
epilepsy, your GP should give you a checkup.
5. Nothing to eat or drink – fasting (‘Nil by mouth’)
The hospital should give you clear instructions about fasting.
It is important to follow these. If there is any food or liquid in
your stomach during your anaesthetic, it could come up into
the back of your throat and then go into your lungs.
This would cause choking, or serious damage to your lungs.
In emergencies where people have not had time to fast,
there are other techniques and drugs that allow anaesthesia
to be given which your anaesthetist will explain to you.
6. Your normal medicines
You should continue to take your normal medicines up to
and including the day of surgery, unless your anaesthetist or
surgeon has asked you not to. However, there are exceptions.
For example, if you take drugs to stop you getting blood clots
(anticoagulants), aspirin, drugs for diabetes or herbal
remedies, you will need specific instructions. If you are not
sure, your anaesthetist or surgeon will advise you.
