Preparing for Anaesthesia

Mr and Mrs Gas Home

PEOPLE WITH MEDICAL CONDITIONS

For patients with chronic medical conditions preparation for your anaesthetic and operation is essential. If you have any of the following conditions make contact with your anaesthetist as early as possible before your operation.

  1. Heart disease.
  2. Diabetes requiring insulin or tablets
  3. Lung disease such as severe asthma or emphysema.
  4. Kidney disease.
  5. Severe arthritis.
  6. Any other conditions that you see a specialist for.

 

Please submit your medical history early via our Online Adult Pre-Op Questionnaire.

Please  have the details of any specialist such as your cardiologist available when you contact your anaesthetist so that they can chase any reports or investigations you have had. We may even ask you to make an appointment to see them for a tune up before your operation.

If your medical conditions are significant and complex we may organise a consultation with you prior to your operation so that we can better assess your needs and better plan for your anaesthetic. This can generally be done at the hospital you will be going to or the surgeon’s rooms.

YOUR MEDICATIONS

In general you should continue all of your usual medications. Some exceptions to this are anti inflammatory meds, aspirin or blood thinners such as apixaban or clopidogrel. If you take any of these medications please discuss this with your surgeon as they will decide whether or not you should stop these medications.

If you are taking any herbal preparations, supplements or Chinese medicine  stop these 10 days prior to surgery. This is because some herbal preparations can cause significant bleeding during surgery or interact with anaesthetic drugs.

If you take medications for diabetes please contact us at least 5 days before the surgery for instructions.  

If you are taking a GLP-1 medication such as Ozempic or Mounjaro let us know in advance

If you are not sure about any of your medications please make contact with your anaesthetist.

PREVIOUS ANAESTHETICS

If you have had a previous anaesthetic and had any problems with it, please let us know as concerns can be often sorted out with a simple email or phone call. Anaesthetics are tailored to an individual and just because you had problems with one previously does not necessarily mean that we can’t alter your next anaesthetic to make it a better experience. Part of your anaesthetic consultation is to discuss this, as every anaesthetic is a prescription of specific medications that your anaesthetist selects as the safest for you.

SMOKING

Smoking and vaping cause many deleterious effects to your general health. It has been linked with an increased risk of heart disease, chronic lung disease, vascular disease, many forms of cancer, early aging and death. Smoking adversely affects your operation and anaesthetic in the following ways

  1. Carbon monoxide from your cigarettes decreases the ability of your blood to carry oxygen during your operation.
  2. Smoking and vaping increases your chances of having acute complications such as wheezing, coughing and respiratory distress.
  3. Smoking and vaping also places you at greater risk of developing post operative lung infections and pneumonia.
  4. You will commonly have a productive cough for several days after your operation.
  5. Smoking and vaping  decreases your body’s wound healing ability, for some forms of surgery such as breast reconstructive surgery it greatly increases the risk of having an unsuccessful reconstruction. This can be so significant that some surgeons may choose not to perform some sorts of reconstructions in patients who are currently smoking.
  6. Smoking increases the chance of post operative cardiovascular complications such as stroke and heart attack

 

Whilst ideally you should stop smoking 6 weeks prior to your operation, stopping at any time prior will be beneficial for your overall health and well being.

FASTING

Generally, you will be asked to fast from milk, solid foods, and other liquid food and drinks for 6 hours, though you can drink water freely until two hours before your surgery.

If you are taking GLP-1 injections or tablets such as Ozempic or Mounjaro, a specific and strict clear fluid fasting plan is used.

Please review the official ANZCA GLP-1 Agonist Patient Information Sheet for detailed guidelines.
