Frequently Asked Questions
The information on this page is intended as a quick guide for people undergoing surgery with sedation or anaesthesia. The questions listed are examples only. They are useful reminders that are also contained, along with other information, in the Society’s brochure “Your Anaesthetic” which your Anaesthetist will talk to you about when you meet to discuss your surgery.
Please tell your Anaesthetist about your medical history and any problems that might affect your surgery. This will help the doctor when planning your surgery. This health information is private to you and your doctor.
The answers to frequently asked questions do not replace the independent medical advice of your anaesthetist or surgeon. Your doctor is trained to assess and manage your personal health and treatment.
This is very unlikely. In low risk surgery and anaesthesia the risk of waking during the operation is around 1 in 40 000.
Your Anaesthetist stays with you the whole time during the procedure and keeps giving you anaesthetic drugs until the Surgeon has finished the operation.
However, everyone needs different amounts of these drugs to ensure they are pain free and fully anaesthetized. Your Anaesthetist will be constantly assess you and tailor the anaesthetic to balance the risks to the type and length of operation.
Always tell your Anaesthetist about any vitamins, herbal remedies, homeopathic remedies or supplements you are taking, as many of these interact with conventional drugs and anaesthetics. As a rule of thumb do not take non-prescribed medications for the week before surgery unless they have been discussed with your Anaesthetist.
Different insurance policies have differing levels of cover. In generally only premium policies cover the entire costs of an operation. Usually there is a small difference between actual costs and those which are covered. You should discuss this with your anaesthetist and your insurance company.
Most anaesthesia drugs have no long-term adverse effects. Unless there is a serious complication there is little chance of permanent brain injury. However infrequently, serious complications can occur. Your anaesthetist will talk about the level of risk for you if you decide to have surgery.
No. You should try to organise your surgery to occur after any examination or other intellectual event. There is some evidence of temporary changes in memory and mental function.
In the elderly confusion is not uncommon although it is not usually permanent. For the elderly a change in environment and the events associated with surgery can result in confusion. Ideally, the elderly should get back to their own homes where familiarity will help reduce any confusion.
Not unless the procedure is under local anaesthesia. Postoperative pain or nausea and small but reversible changes in memory and mental function mean you must have someone with you. Try to arrange for a friend or family member to stay with you. Otherwise you are best to stay overnight in hospital.
In many private hospitals the hospital owns the anaesthesia machine and supplies the drugs that the anaesthetist uses to give your anaesthetic. An invoice for anaesthesia costs is to cover machine and drug costs.
The anaesthesia bill is usually a charge for the anaesthetist’s time and skill in the same manner as a surgeon’s bill. This will be based on time spent in the operating room, as well as preoperative and postoperative care and the risks associated with the procedure.
Yes there are four main types: general anaesthesia, regional anaesthesia, local anaesthesia and sedation/monitored care. You can see more about these under Your Anaesthetic.
Yes. Smoking is a major health hazard and can result in serious health issues. For anaesthesia it can result in an increased risk of breathing complications. Ideally you should stop six weeks prior to surgery.
Yes. You must inform your anaesthetist of any recreational drugs you take. These may result in some serious drug interactions which the anaesthetist needs to avoid. Drugs such as ‘P’ are a major risk and may result in fatal reactions. You should not take any recreational drugs for at least 1 week before surgery and must always inform your anaesthetist when they were last taken.
That will depend on the procedure and the nature of your cold. If you have chest symptoms, for example a productive cough, your procedure should be delayed. Similarly, if you have had muscle aches and pains associated with your cold surgery would be delayed. A runny nose or sore throat alone is not usually a reason to delay your surgery.
No. Anaesthesia is a drug-induced unconsciousness; it is not normal sleep. Under anaesthesia you will have no indication of the passing of time or awareness of any events.
No, bring your dentures with you. Generally anaesthetists prefer that you leave you dentures in place when they send you off to “sleep”. If required they will take them out.
If you have a partial plate the anaesthetist may prefer it to be left on your locker or with someone for safe keeping prior to your procedure. Please check with your anaesthetist.
Yes, children need to know what to expect and to know that they can trust their parents. Surprises cause distress and anxiety. You should let them know what is likely to happen throughout the procedure.
You should contact the hospital initially and they may advise you to come back or may be able to organise some medication for you.
If it is very bad you may need to get an ambulance to the hospital as it may be a complication of surgery. If you have had your procedure privately you should call your surgeon for advice.
